Ignition module is better for VAZ 2110 injector 8 valves

Ignition module

As mentioned above, the “ten” has 4 engine types: 16 and 8 valve internal combustion engines, as well as with a volume of 1.5 and 1.6 liters. This will lead to differences in the ignition modules. Depending on the installed engine with a certain volume, its own ignition module will be installed.

Differences

The main differences between the modules will be the size and mounting holes. In a 1.5 liter internal combustion engine, the ignition module is larger in size in contrast to the 1.6 liter engine. The cost of the modules depends on the manufacturers, but it should be noted that the MZ from a 1.5 liter engine is always more expensive than a 1.6 liter one.

16 valve MZ

In a 16-valve internal combustion engine, the ignition module is installed on the valve cover near the oil filler neck.

8 valve MZ

The MZ on an 8-valve engine is installed on the front of the cylinder block between the dipstick and the breather.

Priora, 2170-2173

The Lada Priora is equipped with the same ignition coils as the Kalina. The coil is marked 2112-3705010-12. Just as in the case of Kalina, Priora is equipped only with injection engines, so carburetor ignition coils or “bobbins” cannot be installed on the car.

To summarize, it is worth saying that when choosing an ignition coil for a car, it is necessary to take into account the marking of the part, its compatibility with a particular model of the domestic automobile industry. Despite the high interchangeability, attention is also paid to the overall dimensions of the part and the type of fastening in the engine compartment of the car. You can purchase coils or ignition modules for domestic “classics”, “Samara” and “Sputniks” in our online store with a few clicks of a computer mouse.

VAZ 2110 was born back in 1996. The first models were produced with an 8-valve carburetor engine. Then the carburetor was replaced by an injector and even a 16-valve engine, which was first installed on the VAZ 2112.

Accordingly, with the advent of the injection system, many different electronic sensors appeared in the car, such as the ignition module.

In this article we will talk about the ignition modules for the VAZ 2110-12, namely its symptoms of malfunction, checking, cost and do-it-yourself replacement.

Device

The ignition module has a common structure regardless of engine size. Inside the switch there are two high-voltage coils and an electronic circuit with many keys.

The coils are designed to switch high voltage and supply it to the spark plug to form a reliable spark in the combustion chamber of the engine.

The ignition module produces a spark in pairs, that is, each of the coils located inside the module is responsible for generating a spark on two cylinders: the first-fourth, the second-third.

Symptoms of a problem

Based on some signs, it can be determined that the culprit of a malfunctioning internal combustion engine is the MZ. Below is a small list of symptoms indicating failure of the MH.

• Failure of two cylinders at once, namely 1-4 or 2-3;
• Increased fuel consumption;
• Detonation at idle speed;
• The engine does not develop power;
• Difficult starting on a hot internal combustion engine;

These signs indicate a malfunction in the ignition system. These signs also apply to other possible breakdowns: spark plugs, wires and even injectors, but first of all you need to pay attention to the MH.

Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

Conclusion

Does it make sense to use such an improved car ignition system?

Module check

After signs similar to failure of the ignition module appear, it must be checked before buying a new one, since its cost is not cheap.

There are three ways to check: substitution, visual inspection and a multimeter.

Substitution

The best and easiest way to check the MZ is to install another known good one from another exactly the same car. After which it will immediately become clear what the matter is and whether the Ministry of Health is to blame for this problem.

Visual inspection

It is necessary to inspect the module for chips, cracks, etc. There should be no damage to it. There should be no moisture or rust on the contact part.

Multimeter

Testing with a multimeter is carried out using the results of voltage and resistance measurements. This will help identify the cause of the failure of the module or its control circuit.

Step by step check

• Remove the power supply from the module. On the multimeter we set the DC voltage measurement limit to 20V. We turn on the ignition on the car and connect the multimeter contact on one side to the power block (namely to connector 15), and on the other side to the engine housing. The voltage between pin 15 and the motor housing must be at least 11-12V. Otherwise, the power supply circuit of the MH is faulty, or the battery is discharged.

• Next, we check the resistance on the VAZ 2110 ignition module itself. We set the multimeter to the resistance measurement parameter, namely 200 Ohms. We connect the multimeter probes to the high-voltage terminals of the MZ: 1-4, 2-3. The resistance of these coils, with a working MC, should be within 5 ohms.

• Then the resistance at the MC input is checked. One multimeter probe is connected to the central contact and the resistance is measured first on the leftmost contact and then on the rightmost one. The resistance should be in the 5 ohm range.

Replacement

Replacement is quite simple and effortless. To replace, you will need a ratchet with an extension and a 10mm socket.

Replacement process

• We remove the negative mark from the battery, since the work is carried out on the electrical equipment of the car. This will avoid an unintentional short circuit in the vehicle's network.

• We remove the high-voltage wires from the MZ and the power connector.

• We unscrew the nuts securing the MZ and dismantle it.

Pay attention to the order in which the wires are connected. Do not confuse them, otherwise the car engine will not start. Cylinder numbering starts from the timing mechanism from left to right. Connect the wires as it is written on the Ministry of Health.

Cost and article

The table below shows the cost of the VAZ 2110 ignition module depending on the manufacturer and VAZ engine size.

Original or analogue?

There are more than 10 different manufacturers of ignition coils on the market. Depending on this, the price for IKZ can vary significantly. For example, good imported ignition coils for VAZ engines can now be found for 1500-1800 rubles. Cheaper Russian analogues will be 2 times cheaper.

It is worth considering that a fake part will have a significantly shorter service life than the original part. For example, according to reviews from owners, after installing Chinese ignition coils, the “cylinder misfires” error almost immediately appeared and the engine began to tune up. After 500-1000 km, the ignition coils completely failed.

We check the ignition module on the injection VAZ-2110 8 valves with our own hands

At different times, different engines were installed on the VAZ-2110 car, both carburetor and injection. However, regardless of the type of power system and the number of valves (8 or 16), all engines are assembled on the unit base of the old engine 21083 and 21093. The most progressive of these engines is the 16-valve 1.6-liter VAZ 21124 engine with a power of 89 horsepower. Today we will touch on the ignition module for 8-valve engines 2111 and 21114 (1.6 l), check its performance and find a suitable replacement for the failed module.

Version of the module on the 8-valve VAZ-2110

The top ten was equipped with two 8-valve engines of different sizes - 1.5 (2111) and 1.6 liters (21114). The ignition modules for these engines are different.

• The one and a half liter engine has a module with article number 2112-3705010,
• and the 1600 cc is equipped with module 2111-3705010.

A module for a 1.5 liter engine costs about 1500-2100, and the second one is 500 rubles cheaper.

Which is better?

SOATE devices manufactured in Stary Oskol have proven themselves to be the most reliable ignition modules.

Module structure

The module consists of two ignition coils and two high-voltage switch switches.

Inside the module there is a board with radio components and ignition coils filled with compound.

The coil generates a high voltage pulse, and it is a simple transformer with two windings, primary (induction voltage about 500 V) and secondary (induction voltage at least 20 kV). All this is assembled in a single housing, on which there is a connector for signal wires (from the engine control unit) and four terminals for high-voltage wires.

Schematic diagram of the module.

The module operates on the principle of an idle spark - it distributes sparks in pairs to cylinders 1-4 and 2-3 according to impulses transmitted from the ECU.
