Temperature sensor for the 4th generation LPG reducer digitronic

Among car enthusiasts and specialists, discussions often arise on the topic of optimal fuel consumption in the form of gasoline or gas. As practice shows, gas-cylinder equipment is more economical during operation. However, its installation requires capital investment. In the Russian Federation, Digitronic equipment is in demand. It is the Digitronic HBO that will be discussed in our article today.

About the Digitronic brand

In 2004, the engineering and management staff of GAZPART 95 began developing the foundation for a new brand. The idea was to use a wide range of high-quality components from various manufacturers. According to the technical specifications of Digitronic specialists, work is being carried out to manufacture equipment at the Italian plant AEB (Alternative Fuel Electronics). However, there are components from other countries. For example, from the Polish company STAG. And this is one of the Digitronic policy lines, in which there are no restrictions in the selection of a high-quality assortment.

In many respects, gas cylinder equipment of this brand can be considered universal, because it can be installed on different car models. It is important that these products are applicable to trucks and passenger vehicles.

BRC

One of the most famous Italian brands of HBO manufacturers. All components are produced at the same factory and adjusted to each other. HBO BRC is a high-quality product that will last a long time. But like all high-quality equipment, equipment from this manufacturer cannot be cheap.

The advantages include:

  • High quality products;

Multivalve

Gas systems of any type must be equipped with shut-off valves. For cars, a multivalve is used, which combines up to ten functions, in addition to shut-off. The device includes several elements: actuator, shut-off, control and safety. Multivalves can also be divided into two types: without a safety valve with a volume limitation for equipped cylinders and with a valve.

Device functions:

  • Possibility of manually shutting off the fuel supply;
  • Availability of gas supply speed control;
  • Blocking the loss of the gas mixture in the event of a disconnection from the filling column;
  • Emergency gas release in case of cylinder depressurization;
  • Fuel level sensor.

Other elements

The Digitronic company supplies gearboxes, injection racks, pressure gauges, filters and peripherals to the Russian market.

There are seven types of gas reducers in the product catalog. This is the main element in the car's gas system. It serves to reduce the pressure of the gas mixture to a level at which it can be supplied to the engine. They differ in the type of gas mixture used (propane or methane) and the power of the engine for which they are designed. Methane gearboxes AT-12 and AT-12HP are designed for engines with power up to 250 and up to 400 horsepower, respectively.

Methane reducer

Maximum power for propane gearboxes is up to 300 horsepower DIGITRONIC PALLADIO. At the same time, their selection is extensive and allows you to choose a model for the most popular engines with low power. Thus, the DIGITRONIC ALASKA gas reducer is designed for cars with an engine up to 120 horsepower. All samples have a built-in liquid phase filter. This eliminates the need to install an additional valve. An advantage of the DIGITRONIC ANTARTIC SUPER gearbox is that it can be completely disassembled, making it easier to repair in the event of a malfunction. In addition, its gaskets are made of material that is resistant to aggressive environments. This gearbox is designed for engines up to 240 horsepower.

Gas filters are presented in four modifications with similar characteristics. Their connection diagram is the same. They can operate at temperatures from -20 to +120 at a pressure of 450 kPa. This element is installed between the pressure sensor and the reducer and serves to purify the gas mixture from foreign impurities. It is important due to the varying quality of gas sold on the Russian market, which can cause problems.

Digital connection diagram

A gas filter reduces the possibility of their occurrence to a minimum.

An extensive selection allows you to choose a part for almost any car.

Twelve types of hoses are produced under this brand. They are intended for both gas mixtures and other vehicle systems (gasoline, antifreeze, vacuum). Their diameter is from 5 to 16 mm, operating temperature is from -25 to +125. The equipment is certified according to international standards.

Digitronic kits

The company supplies both individual components and kits for engines with different numbers of cylinders.

A comprehensive solution involves the selection of each element, which affects the efficiency and stability of the entire system as a whole. The set of gas equipment includes:

  • Switch between gas mixture and gasoline (Gas-gasoline button);
  • Cylindrical or toroidal gas cylinder with a volume of forty liters or more;
  • An electromagnetic valve with a filter, designed to remove impurities from the fuel mixture and performing a shut-off function;
  • A ventilation box, which includes shut-off valves and valves, the purpose of which is to reduce the risk of an emergency in the event of a gas leak;
  • Reducer - an evaporator through which liquefied gas passes into the gaseous phase;
  • Valves for gasoline and gas are electromagnetic type to stop the supply of fuel to the combustion chamber.

Mounted injector rails, gearbox temperature sensors and an electronics kit can also be supplied.

Controller Features and Functionality

The production of an electronic control unit for gas systems is established in Polsky, whose products have long proven themselves in the gas equipment market.

The device was developed on a 32-bit high-performance processor, has a compact design, assembled in a sealed plastic case, convenient for installation.

According to the manufacturer's plant, the electronic control unit for gas equipment of the 4th generation digitronic maxi two, compared to its predecessor (maxi-1 (also discontinued digitronic four maxi)), has increased quality and reliability, proven by numerous tests. In addition, for a moderate cost, the average price for the original Maxi-2 electronics kit, which includes a map sensor, a gas/gasoline button, and a wiring harness, is 7,150 rubles.

Also, based on reviews from car owners, we can conclude that no global problems arise during the operation of a gas system with a maxi-2 controller.

The causes of malfunctions are usually:

  1. poor installation
  2. non-compliance with the service interval (TO)
  3. The supplied controller is not the original one.

Digitronic control unit MAXI 2

For four cylinder engines, Digitronic has developed the MAXI 2 control unit. This line is designed to reduce installation and calibration time.

The basis of the unit is a thirty-two-bit processor with the possibility of upgrading. Such a unit can be quickly installed thanks to a small number of wires and a sealed compact housing. Calibration is carried out through functions located on two panels, which eliminates the problem of switching between tabs. There is a separate button with a buzzer, which is connected using three wires.

The software capabilities of the unit include displaying engine operating parameters on an oscilloscope, a gasoline injection time map in 2D format, functions for correcting gas pressure and temperature with corresponding maps, heating gas injectors, setting the maximum load on the gas mixture, changing the time for opening and closing injectors, as well as the flow through them, and much more.

The MAXI 2 unit is compatible with almost forty manufacturers of gas injectors, including AEB, Hana, Valtek, Rail, Matrix. Functional and software characteristics have made Digitronic MAXI 2 one of the most popular on the Russian market.

Reasons for malfunction of the gas temperature sensor

Any, even very good equipment can break. HBO temperature sensors are considered durable devices. They break extremely rarely. The gas ECU that controls the operation of the injectors gives a signal that is adjusted by several main factors:

  • pressure arising in the nozzle rail itself;
  • heating antifreeze;
  • gas temperature.

If any of the listed components fails, the LPG ceases to function normally. The coordinated operation of all equipment components is disrupted. The probable causes of a malfunction of the gas temperature sensor are:

  1. If there is voltage on the device, but its signal does not reach the ECU. Consequently, contact between these devices has disappeared. To find the location of the breakdown, it is necessary to diagnose the connecting wires.
  2. There is no tension at all. There may be no power supply. If, after applying current, the sensor is still silent, it means that it is completely broken. To determine the unavailability of power, a “ring” is made of all suitable cables, the pressure sensor, as well as the temperature sensor itself.

After eliminating the malfunction, the functionality of the device is fully restored. If, after eliminating breaks in the electrical system, the device still does not function, replace it.

If an electronic component receives incorrect information from a temperature sensor, this is rarely due to a breakdown of the device. Most often, the cause of such a breakdown is caused by incorrect adjustment of the product.

To correct the situation, you will need to first diagnose the system. For this operation you will need:

  • connecting wires;
  • software;
  • computer.

When setting up the system, it is necessary to take into account the modification of the gas equipment and the model of the car on which it is mounted. Such an operation cannot be performed without experience and special knowledge.

Digitronic control unit IQ series

This line is intended for engines with a number of cylinders other than four. Each IQ block model is installed for its own number of cylinders. The functions of the IQ block include:

  • Automatic closing of the solenoid valve if the temperature at the gearbox drops below 10ºC;
  • Correction of the volume of injected gas;
  • Indication of target OBD corrections depending on engine speed with a map;
  • Fuel level emulator (for cars whose gasoline indicator drops when switching to gas fuel);
  • Correction of the volume of injected gasoline along with gas;
  • An oscilloscope showing the operation of gas and gasoline injectors, as well as engine speed;
  • Flow calibration on gas injectors;
  • Open Loop adaptation for closed and open loop.

Depending on the specific interface version and block model, the set of functions may differ. The electronic control unit system has been carefully designed down to the smallest detail, minimizing the adjustment of gas equipment after installation.

Step-by-step instructions for setting up gas equipment

The vehicle must first be warmed up to operating level. Then remove the load (heating, air conditioning, air conditioning, etc.) from the engine so that the car remains idling. Before entering the parameters menu, you need to connect to the gas equipment using a special cord. If necessary, the software must be updated to the latest firmware version. Algorithm for setting up Digitronic gas equipment using special software:

  1. Set the basic parameters of the car (number of cylinders, engine type, etc.), and in the “GAS Controller Settings” tab select the type of injectors, temperature sensors, etc.
  2. In the calibration section it is required to indicate the operating and emergency gas pressure. Calibration setup is done automatically using the ISA-2 adaptation tool. It must be carried out on a warm internal combustion engine (internal combustion engine).
  3. When the procedure is completed, the system prompts you to take a ride to set up the gas map. While driving, a map consisting of multi-colored cells will be displayed on the laptop monitor. It is necessary that the maximum number of them turn black.
  4. After receiving sufficient information on the use of gasoline fuel, you should switch to gas and continue driving.

Filling out each card usually requires driving several kilometers. The curve of the petrol and gas maps should be as close as possible. If they do not match, you need to adjust the coefficient:

  1. Place a mark on the orange curved line at the point where the two graphs diverge.
  2. Place a point on the orange curve at the convergence of the blue and green lines.
  3. Select the area of ​​greatest deviation of the gas and gasoline curves. This point must be clamped and moved so as to minimize misalignment.
  4. Make another trip by car to generate new maps. If they do not match again, you need to try the whole procedure again.

The coincidence of the map graphs is not a 100% guarantee of the correct fuel mixture. After the initial setup, you need to drive the car for some time to observe the “behavior” of the curve. If necessary, additional steps must be taken to obtain the best result.

Selecting the right gas mixture

To determine the optimal fuel characteristics, it is necessary:

  1. Start the car and warm up the gas fuel and gearbox to operating condition.
  2. Switch the vehicle to gasoline and let the engine run for about 10 minutes. Observe in the program how the injection time changes. It is recommended to additionally monitor the fuel trim and lambda.
  3. Switch the car to gas and check how the fuel injection timing changes. An increase indicates a poor gas mixture, so the electronic control unit tries to enrich it. It is necessary to ensure that the injection does not change when switching from gasoline to gas. To do this, you need to move the orange curve up or down until the desired result is achieved.

A deviation of 10% is allowed. The software allows you to adjust other parameters in order to more accurately configure the operation of gas equipment. It is not easy to set the correct characteristics on your own, so it is better to contact a specialist who will optimize the operation of a car on a gas fuel system.

specializes in installation and maintenance of gas equipment in St. Petersburg. Experienced craftsmen will quickly and accurately adjust gas equipment to obtain optimal performance.
