Glad to welcome you again, friends! In our country, everyone knows that if a man drives a domestic classic, then he knows the mechanics exactly, and no breakdowns matter! It doesn't matter if the car drives or won't start, we will find the reason and repair the car!
Let’s simulate a situation: on a frosty winter day it’s early morning, and the temperature outside is 20 degrees below zero or even higher. When you finally opened the frozen door and sat down in the cabin, you realized that the car would not start. While you are pondering the possible cause, an experienced person will remember how to light the spark plugs in your home since the cause is obvious. If you were a driver from the USSR, you would probably have time to work, but the chance not to be late is also yours! Don't miss out, read on!
Auto parts and service stations
Many owners of vehicles, especially those belonging to the domestic automobile industry, often experience in winter that the spark plugs turn black or acquire a dark tint. In this case, a logical question arises: what needs to be done to solve the problem? The answer in this case is simple - clean the components. It is worth noting that cleaning can be done on your own. Let's try to figure out how to clean spark plugs from carbon deposits. In addition, this material will discuss the reasons for this situation.
Features of cleaning spark plugs at home
Cleaning spark plugs at home is a fairly common cleaning method. In this situation, it is necessary to remember that the insulator included in the structure can simply be damaged or scratched by careless movement . Of course, allowing such a situation to arise is highly discouraged. Otherwise, problems with the formation of carbon deposits on the surface will worsen. That is why the cleaning process using sandpaper or any other devices is unacceptable. The ideal option as a tool for restoring the structure of candles is to use a brush. However, it must be made of steel wire. A regular toothbrush may also work.
Speaking about how to clean spark plugs from carbon deposits, we cannot help but talk about the use of sandblasting equipment. It should be noted that this method of cleaning is widely used at many vehicle service stations. The process of removing carbon deposits from the surface is carried out through the use of various types of sand, as well as the use of blowing through compressed air. It is generally accepted that this method is one of the most effective and allows you to return the component to normal, working condition. At a very reasonable price, this method allows you to restore the part as quickly as possible.
When talking about how to clean spark plugs, we cannot fail to mention sand. Thus, a separate category of “craftsmen” inserted the part into the chuck of an electric drill and turned it on, having previously placed it in a container with sand. Of course, the method may seem very strange. Moreover, this method of cleaning spark plugs from carbon deposits is effective. Having certain qualifications and experience in this matter, the method will not differ from where sandblasting equipment is used.
How to clean spark plugs at home using heat
If you are thinking about how to clean spark plugs from carbon deposits, then you can use a fairly common method that involves thermal exposure. This option involves burning the component. As a rule, this method is used if new spark plugs were filled during a “cold” start. It’s a pity to throw away such components and, as a result, people decide to carry out the drying process. It should be noted that in this case there are several main methods. Among them are:
- Calcination using a soldering iron.
- Calcination using a gas-type stove.
The method is not particularly complicated. At the same time, car owners who have used it recommend not calcining the spark plugs too much.
Chemical cleaning method
It is also possible to revive spark plugs using chemical-based products. This method allows you to remove carbon deposits from these components as quickly and without problems as possible. In order to perform this procedure, you should buy a simple detergent or liquid that is designed to clean carburetors. You can also clean spark plugs with vinegar.
A cleaning procedure using a rust remover is also permitted. To use this method, you need to unscrew the part and apply a layer of several millimeters to their surface. Next, you need to wait half an hour and clean the surface by rinsing with water. It may seem very funny, but the cleaning process is also carried out with the help of Coca-Cola. There are rumors that orthophosphoric acid, which is included in many drinks, can most effectively cope with the carbon deposits that have appeared on these components.
Speaking about cleaning with vinegar, first of all it should be said that this method is quite old. In this case, it is necessary to place the candles in a container where vinegar has previously been poured. The components must be kept in this container for one hour.
You can also clean spark plugs at home using ammonium acetate . Initially, candles must be subjected to a degreasing procedure. Next, they need to be washed using gasoline fuel. At the final stage of this type of procedure, the drying process is carried out. It is necessary to immerse the candles in a 20% acetate solution. They should stay in it for about thirty minutes. In this case, the temperature should be at least 90 degrees. When carrying out the cleaning process, you must make sure that the room is well ventilated. The fact is that the fumes emitted by acetic acid negatively affect the human body due to the fact that they are poisonous.
It should be noted that spark plug restoration can be carried out in other ways. At the same time, a fairly large number of them are difficult to implement. That is why their use is recommended for those people who have work experience.
How to check spark plug operation
Of course, as soon as cleaning the spark plugs with your own hands has been done, it is necessary to carry out a procedure that involves checking their functionality. It should be noted that in this case you need to install the components back and try to start the car engine. If you understand how to properly clean spark plugs, then there will be no problems with this procedure. Please note that the car should function without any problems.
How to Restore Spark Plugs Reliably
Situations when a person does not have the opportunity to independently perform work of this type are not so rare. That is why if you are not sure of the correctness of performing the procedure yourself, it is recommended to contact specialists who are competent in this matter. It is worth saying that they will not only be able to tell you how to perform the procedure for cleaning spark plugs, but will also help you complete this work. Note that this approach provides an additional guarantee that after cleaning from carbon deposits, the parts will remain operational.
If, after performing the cleaning procedure, the problem has not been solved, then the only way out of this situation is to purchase new parts that need to be installed. You can do this yourself. Also, the procedure will take no more than a few minutes in a specialized service center. In general, you need to understand that if the spark plugs have been subjected to a restoration procedure, sooner or later they will need to be replaced.
Conclusion
If all vehicle systems are functioning correctly and the quality of the fuel used is high, then the spark plugs need to be cleaned. As soon as their operational period is completed, they must be replaced with new ones. At the end of the operational period, proper cleaning of the spark plugs will no longer help solve the problem.
the candles were flooded during cold weather , then the only correct way to solve the situation is also to clean the component. You do not need to remove the part to do this. It is enough to start the vehicle engine and let the engine run at sufficiently high speeds. By approaching the issue of servicing your car correctly, you will not have any significant problems with it.
Cleaning spark plugs at home is a fairly common cleaning method, but you need to be careful not to damage the insulator.
How not to clean spark plugs: don't be fooled by nonsense!
Regular readers know that the vast majority of articles on this resource are honest copy-paste of each other. And so, once again scrolling through the feed, I came across a note from one “top” autoblogger about cleaning spark plugs. Or maybe not just one - I repeat, the guys stupidly “lick” each other’s articles, sometimes even practically without changing the title. And I, as a person writing exclusively from the perspective of my own (very rich) practical experience, and not mindlessly rewriting jaundiced Internet notes, I really want to warn you
.
A widely known method of chemical
cleaning the electrodes and the lower surface of the insulator of spark plugs with high mileage. It consists of placing the lower part of the part in a jar with a rust converter, a cleaner for cooking stoves and other powerful compounds. And then, after a couple of hours, you take out the spark plug, wipe it with a cloth - and beauty! Like new. And everything would be fine, but...
How does carbon deposits come off the spark plug electrodes?
Due to the acid, my friends. And those who have already conducted various kinds of experiments know very well - neither solvent, nor kerosene, nor other nephras ( petroleum solvent
) this soot is not taken at all. Why? Right. There's no acid there. It is this that neutralizes all the blackness that has accumulated on the spark plug over months and years.
In general, are you sure that the candle itself is to blame for this. But if everything is much more decent with you, then why clean anything at all?
The carbon deposits are gone, the spark plug is clean - profit.
Nope. Although it has become clean, strictly speaking, you have ruined it. The fact is that the central electrode has long been covered with a thin layer of alloying compounds: yttrium, iridium and other fancy words. For what? Since this element is the most thermally loaded
(approximately 600-800 degrees operating temperature). And it is this kind of spraying that is designed to partially protect the electrode from melting, and at the same time minimize the effect of “sticking” of combustion products to the metal. Very rough, it can be compared to the Teflon coating on frying pans.
So, under the influence of acid, this microlayer comes off along with carbon deposits. After which the electrode loses its original properties
. A given heat resistance, the ability to form an electric arc in a calculated manner and that very carbon deposits that you were fighting against.
Even in citric acid it sizzles beautifully, the dirt falls off wonderfully, but... But the actual performance characteristics after such a procedure only became worse.
How to clean correctly?
Yes, strictly speaking, no way. Well, this is not a part to bother with servicing. On a working modern engine, spark plugs can easily last 60 thousand kilometers or more (as intended). These are not words of advertising, this is, again, personal practice. And if at every oil change you unscrew the spark plugs and see that they are all coated with dirt and carbon deposits, then this is a reason to think about the condition of your car’s engine, and not about how bad the spark plugs are and how to clean them as quickly as possible.
But if it really itches, then you can clean it. But it’s long and tedious (but without damaging the details). This is the old-fashioned method of heating over a stove with periodic back-and-forth movements with a stiff toothbrush. It takes a long time, is ineffective, and you cannot achieve beautiful “factory” cleanliness, as is the case with acid. But it is relatively safe for the spark plug itself. But whether such a game is worth your candle is up to you to decide.
Cleaning spark plugs with harsh abrasive treatment is especially prohibited.
I hope it will be useful to someone!
Clean spark plugs and less bad advice to everyone!
Causes of malfunctions
Spark plugs and malfunctions are associated with the appearance of:
- Wear, usually of the side electrode.
- Crack in the insulator body.
- Melting of both electrodes.
- Erosion – thinning of the side element.
- Carbon deposits.
Wear
Failure to replace spark plugs in a timely manner leads to distortion of the gap and, as a result, sparking with the consequences of poor starting of the car. Wear of the side electrode is caused by additives contained in gasoline. The result is missed sparks and engine detonation. Products are subject to replacement.
Cracked spark plug body and insulator
Even unnoticeable cracks or visually visible chips or chips on the body of the insulator are considered reasons for replacement.
When using spark plugs with cracks, current leaks through the insulator to the spark plug body
Defects appear as a result of:
- wear and tear (natural).
- Detonation due to early ignition angle.
- Low octane fuels.
- Low quality insulator.
- Incorrectly set gap.
A defective spark plug insulator causes current leakage. This fact leads to a decrease in the spark discharge between the electrodes. And this is already a difficult engine start, low throttle response, jolts when moving from a stop, unstable idle speed.
Reflow
Melting of electrodes is a manifestation of serious overheating
The appearance of rough, porous soot. Occurs due to thermal load, low octane gasoline, early ignition cycle. Defects in the distributor (distributor) or valves cannot be excluded. Mixture formation and ignition are checked, spark plugs are changed.
Erosion
Signs of erosion appear on the electrodes of spark plugs that have exhausted their service life.
Caused by oxidation and incorrect gap setting. Erosion will dominate the interaction of lead in gasoline. This presence creates a chemical reaction with, for example, nickel electrode material.
Layering
A pronounced brown-yellow, thick layer of plaque is evidence of the presence of additives (ethyl) in the fuel.
Being a current conductor, carbon deposits lead to distortion of spark formation (at high loads). Since it is useless to remove such deposits, there is a need for replacement.
How to calcinate spark plugs - the best ways
Author:
Maxim Markov
Glad to welcome you again, friends! In our country, everyone knows that if a person drives a domestic classic, then he definitely understands mechanics, any breakdown will not matter to him! It doesn’t matter at all whether the car stalls or simply won’t start, the reason will be found and the car will be repaired!
Let's simulate the situation, early in the morning of a frosty winter day, outside it is 20 degrees below zero, or even more. Finally opening the frozen door and sitting in the cabin, you realize that the car refuses to start. While you are speculating about the possible reason, an experienced person would already remember how to calcinate spark plugs at home, because the reason is obvious. If a driver from the USSR were in your place, he would definitely be on time for work, although you also have a chance not to be late! Don't miss it, read on!
Car requirements
If a vehicle has scored less than 100 penalty points, then it is recognized as a classic vehicle, and the new GOST will be applied to it. If you deviate from the original, points are deducted; if they are consistent, they will be awarded. If a car owner has scored 120 penalty points, then if a major criticism is eliminated by 25-30 points, he will undergo an examination. After passing such an examination and receiving less than 100 points, the car can become a full-fledged participant in road traffic.
The requirements for vintage cars are simpler, and they will be dealt with by their own experts. Replacing the engine would be a serious violation. But if the car owner returns the previous unit to its place, then he can undergo an examination and receive a passport for a classic vehicle.
Of great importance in determining the requirements is Section 7 of the said GOST “Technical requirements for classic vehicles for permission to drive on public roads and verification methods”: it specifies the requirements for the car’s brakes, steering, wheels, lighting, etc. Classic status vehicle for a car that has accumulated less than 100 penalty points is issued for a period of up to 5 years
Classic vehicle status for a car that has accumulated less than 100 penalty points is issued for up to 5 years.
All existing methods
So, what would be the first actions of an ordinary Soviet driver in such a situation? In fact, calcining spark plugs is a whole complex of absolutely not complicated, but still actions. First of all, you need to establish which spark plug is at fault; to do this, you will have to unscrew all four and inspect them for moisture, carbon deposits and octane aroma.
The heating value of spark plugs can be increased only by “general cleaning” on the electrodes. You need to clean the device as much as possible, but simply “wiping dust” will not be enough! Believe me, gasoline and carbon deposits are not so easy to remove without special preparation!
Although, on the other hand, you can’t guess here: sometimes ordinary scraping with a knife can help, and sometimes calcination turns out to be useless.
From my own experience I can say that in the absence of a spare set of spark plugs, this is the only option to make the car drive again.
Calcination by fire
Most often, drivers resort to the method of hot cleaning the spark plug. To do this, you need to burn the part by any means; forgetting about safety is not recommended! The procedure itself looks simpler, simpler: grab the candle with pliers and hold it on the flame until the gasoline stops burning out.
Note: calcination ends the moment the candle stops emitting smoke.
As for the source of fire, it could be anything! While at home, for example, you can do everything in the kitchen on gas, of course, while your spouse is not looking). If this is not an option for you, I recommend using a regular gasoline burner; you will agree that it is a necessary thing in any garage! When “trouble” takes you by surprise on the road, you need to use your wits. Light a fire, a rag soaked in gasoline, or even a candle!
Many car enthusiasts often do not know how to properly complete calcination. Is it possible to artificially cool an iridium or any other spark plug? As a result, instead of resurrecting the candle, they finish it off. Without a doubt, porcelain is a durable material, in our case even fire-resistant, but it does not tolerate temperature changes very well and can easily crack. Take your time, leave the parts for 10-15 minutes and they will cool naturally!
When you have succeeded in heating the candles, do not rush to put them in place! Wipe each candle thoroughly, using a knife if necessary. And only after that you can screw them back in, put on the caps of the wires and finally start the car! Now you have definitely managed to raise the heat value of the spark plugs, a table of these values is available, available here.
other methods
No matter how good it is to heat spark plugs with fire, you need to keep in mind that this is not the only effective method. Let's briefly consider all the currently known options.
- Cleaning with a sandblasting machine is the most effective method of all existing ones; of course, calcination at home will not work, only at a service station, by the way, the price is tolerable!
- Manual sand cleaning - some people still manage to achieve the sandblasting effect in their garage, but this will require good skill in working with a drill in reverse.
- Chemical cleaning - use anything, rust remover, Silit, Fairy, vinegar, acetone, phosphoric acid and even Coca-Cola or Sprite.
- Ultrasonic cleaning - this method is used mainly to clean injectors, and sometimes also spark plugs.
Self-cleaning of SZ
There are quite a few ways to perform high-quality cleaning of spark plugs in a garage and completely restore all the working qualities of the elements.
Physical
Quite often, motorists resort to simple mechanical cleaning using sandpaper (zero) or a stiff brush. The spark plugs are removed and the electrodes are simply mechanically cleaned. But this method is only permissible if urgent cleaning is required, for example, on the road. In all other cases, such cleaning will do more harm. Hard materials leave scratches on the spark plugs, which will cause carbon deposits to settle on them more quickly. When cleaning the electrodes in this way, the protective coating can be damaged, and the spark will stop striking in the right place. This is especially true for iridium ignition elements.
Sandblasting
This method can only be used in a car service center, or provided that the motorist has such a device in his garage. The “sandblast” itself, of course, can be bought, but its cost is approximately 6 thousand, and many motorists would prefer to simply buy a new set of ignition elements. True, there are craftsmen who can assemble a sandblasting machine themselves. The device operates using compressed air and a small amount of sand. A dirty candle is inserted into a special hole and air and sand are supplied under high pressure. It is advisable to rotate the candle, and the sand will be able to remove almost any deposits. If necessary, before starting cleaning, it is recommended to bend the electrodes a little and after completing the procedure, adjust the broken gap.
Thermal
If for some reason the candles have been flooded, then it would be most advisable to use the thermal method to clean them. It involves drying the elements using fire. This can be done using a gas torch, blowtorch or on a gas stove. Heat the candle until red and then use a soft copper brush to remove any remaining carbon deposits.
Chemical
The most common and, perhaps, the most effective method of cleaning SZ is the method using chemicals. Before any chemical cleaning method, candles should be thoroughly degreased, which will allow the chemically active substances to start working faster. For this purpose you can use:
Household chemicals. These can be products for removing rust and lime deposits. Some people recommend using vinegar or acetone. A good effect can be observed when using simple Silit. The candles are placed in the selected solution for about half an hour. Then they are further cleaned using an old toothbrush or a hard paint brush. After finishing cleaning, the SZ should be rinsed as thoroughly as possible with clean water. Next they are wiped with a cloth and dried well. "Coca-Cola", "Sprite" or "Fanta". These drinks contain phosphoric acid, which can also make it easier to remove carbon deposits. The cleaning procedure is similar to the previous option. Ammonium acetate 20%. Candles are placed in this solution and heated to approximately 90 degrees. Then the candles are cleaned with a brush, washed and dried.
It is worth noting that the use of this cleaning option requires a well-ventilated area, otherwise this procedure can be harmful to health.
Ultrasonic
This procedure is most often possible only in a car service center. SZ are placed in a special liquid, and ultrasound is directed at them. The cleaning result is usually very good, but, unfortunately, quite expensive - sometimes it’s easier to buy a new set of car spark plugs.
Conclusion
No matter how effective your method of heating candles is, you must understand that this is an extreme measure, it is better not to let it get to that point. I advise you to buy spare ones in advance! Marking spark plugs is something that will help you purchase a truly suitable model, knowing the code of standard spark plugs for your car; you can easily select an analogue in any car store. I am very glad that you finally know how to calcinate spark plugs really correctly and effectively! I am sure that such knowledge will definitely be useful to you, and then remember me). See you in the next publications.
Troubleshooting
To understand whether they are filled with gasoline or not, whether there is carbon deposits on them or not, you need to do a small and very simple procedure. To do this, prepare only two tools: a special spark plug wrench and pliers.
- Turn on the ignition and unscrew the spark plugs. All modern cars typically come with one per cylinder, meaning there are exactly as many of them as there are cylinders in your car's engine.
- Disconnect the unscrewed spark plug from the wires and unscrew one after the other.
- Inspect them all for moisture, carbon deposits and a strong smell of gasoline. If everything listed is present on them, then they need to either be replaced with new ones or cleaned by calcination, which is what we are going to do.

You can heat it on the stove, but you can’t heat it,
It seems clear, but... What is calcination?
You can, of course, warm them up and dry them on the stove.
to calcinate means to heat to the maximum.
No replacement for displacement!
Soak them in silite, but not for long, for half an hour maximum. nuclear chemistry, then the candle will shine. then dry it on gas
but all this is from the evil one, IMHO, if there is nothing to do. I have so much fun with candles from a walk-behind tractor, it has a moped engine
German "Meriva"
Each car has a spark plug tightening torque indicated in its passport data. Opel Meriva uses a spark from a gap of 1.1 mm. Replacement is made with a 16 mm wrench. To gain access, remove the plastic cover, remove the connectors and unscrew the 2 bolts.
The first step is to remove the coil block along with the spark plugs. Carry out an external inspection for the presence of soot and chips. To tighten it, it is better to use a spark plug wrench with a rubber insert. You will also need sprockets for dismantling decorative elements in the engine compartment. For installation, reverse manipulations are carried out, the tightening torque is 25 Nm.
The spark plugs must be crimped with a certain force to the gasket thickness specified by the manufacturer. Ideally, it should be equal to 1.7 mm. But inexperienced repairmen manually turn it up to 1.2 mm, when the risk of damaging the ceramic inserts increases.
Conical spark plugs are more fragile and require torques with a low error of ±2 Nm. Therefore, it is better to buy an original torque wrench. Cheap tools are usually disposable. Good spark plugs also cost a lot compared to the cost of a key.
Household chemicals
If you want to clean your spark plugs yourself, but prefer safer methods that are just as effective, try simple household chemicals.
Regarding the question of whether VD40 can be used to clean spark plugs, I will say this. It will help as an aid for pre-soaking. But it doesn’t work well as a stand-alone carbon deposit cleaner. It is better to use other methods.
As for household chemicals, products designed to remove rust or limescale work well. In fact, this is any product aimed at cleaning and cleaning plumbing fixtures. You just need to soak the candles in this product for a while, and then carefully brush them with a toothbrush. The result depends on many components, including the components used in household chemicals. When finished, be sure to rinse the candles with clean water and dry completely.
It is difficult to say exactly what the result will be. Therefore, I suggest leaving reviews for those who have tried different household products and can speak from personal experience about their effectiveness.
Home chemistry laboratory
Separately, I would like to consider several products that have shown themselves to be good. They really make it possible to quickly and effectively rid spark plugs of accumulated carbon deposits.
You just need to work with them extremely carefully, observing safety precautions.
- dimexide;
- acetic acid with soda;
- hydroperit.
Now let's go through them separately.
In practice, chemical cleaning gives almost the best result possible for doing it at home. Yes, it is optimal to contact a specialized service, where they will clean the spark plugs on a special stand or even on an ultrasonic unit. The last option is the most effective, but also the most expensive. Therefore, only those who are willing to spend that kind of money on restoring several worn-out spark plugs of an automobile ignition system resort to it.
It is worth recalling that malfunctions and clogged spark plugs can lead to a number of consequences. These are situations when the car starts and immediately stalls, or so-called engine detonation occurs. Even if your car just simply won’t start, the spark plugs are one of the first to be checked.
Use of dimexide
Dimexide is able to cope with light and complex types of spark plug contamination. Even if the soot is serious, there is a high probability that the situation will be corrected with dimexide.
Dimexide is a pharmaceutical product intended primarily for treating the skin on the face. But in fact, the composition can corrode many components, including carbon deposits and scale. Using the product is extremely simple. You need to take a small plastic cup, pour 50 ml of the product into it, put it inside the candle and leave for several hours. After which the candles are taken out and cleaned with a simple toothbrush. All that remains is to rinse with clean water and dry.
Efficient, effective and quite simple. I recommend trying it.
Acetic acid and soda
Here you need to use acid (70%) and not table vinegar, since the effectiveness of the latter is extremely low.
The essence is approximately the same as in the previous version. You need to pour a small amount of acetic acid into the candles and leave for at least 30 minutes. But you shouldn’t keep it for more than 3 hours.
When the candles are infused in acid, gradually add literally 1 teaspoon of soda. A chemical reaction will begin. After this, take a toothbrush, treat the candles, rinse and dry.
Hydroperite
This product is sold in pharmacies, presented in tablet form.
Now take a glass. Better made of glass. Fill up to half of the water so that the candles are well immersed. Place 3-4 tablets of hydroperite into this water. Cleaning with hydroperite will occur gradually. Place the glass on a window or in a warm place. You can safely leave it for about a day. Only after a while will an active reaction begin in the form of seething and boiling.
Take out the spark plugs, go over them with a brush or blow with compressed air. Dry and return to place. Check the remanufactured spark plugs for functionality.
Always keep a set of spare spark plugs with you. It’s not for nothing that they are included in a motorist’s kit, even if it’s not mandatory.

Calcination on fire
Having removed the gasoline-filled candles, the simplest action would be to calcinate them on the open fire of any gas stove.
It’s really simple and convenient if you grab each one with pliers and hold it over the flame for a while until the smoke stops emanating from the burning of the gasoline that got there. Therefore, if the car is located near the house, and gas is used at home, then run home to heat the stove on the fire. If the car is parked far from the apartment (house), then you need to keep, for example, an ordinary alcohol burner in the garage, on the flame of which you can ignite candles in the same way. Of course, you can get an open fire, so necessary for calcination, in any other way, but you should be extremely careful with such things in garages or parking lots. There is no question of fires, but no one bothers you to soak some rags in gasoline and step aside to set them on fire.
After wetting, quickly leave the dangerous area and set fire to these rags, and then in the same way, holding one piece at a time with pliers, heat them over the flame. Under no circumstances should you artificially cool a candle. The fact is that its porcelain part, although made of durable and fire-resistant material (porcelain), may still not withstand sudden temperature changes and will easily crack, becoming unusable. This means that after calcination, you simply leave it alone for 10-15 minutes until it cools down naturally.
What gap should I set on spark plugs for gas and gasoline?
Often, after installing gas equipment on a car, the internal combustion engine begins to throttle, failures appear and gas consumption is higher than expected. These phenomena can occur for various reasons, one of the options is misfires due to an increased gap in the standard spark plugs, due to burning of the electrodes when operating on gasoline. Moreover, when switching to gasoline, everything returns to normal. The problem is solved by reducing the distance between the electrodes or replacing the elements.
A correctly adjusted spark plug gap for gas combustion directly affects the completeness of combustion, the efficiency of ignition of the fuel mixture and the stable operation of the engine, so for gas the size is set in the range of 0.7-0.9 mm. But this parameter is very individual and is selected depending on a number of factors:
- type of ignition system used;
- engine model and characteristics;
- conditions and mode of operation of a car with gas equipment.
For more frequent driving on the gas mixture, gaps of 0.7 mm are suitable and vice versa.
