What is the cause of multi-cylinder fire

1. [Pacific Automobile Network ] Causes of multi-cylinder fire failure: ignition system such as spark plug, high-voltage line, ignition coil; fuel system; gasoline, gasoline pressure, fuel injector, etc.; engine system; valve or cylinder carbonization, low engine cylinder pressure, poor valve sealing, etc.

2. Electrical circuit aging, leakage, etc., intermittent ignition failure; ignition coil or spark plug failure, poor ignition or poor conduction; in terms of lines, loose, broken skin and iron, etc. Man-made operation reasons, such as carelessness or mistakes during maintenance: faults caused by touching, loose plugs, etc.

3. Today, the editor is here to explain the relevant knowledge about "what is the reason for the fire of the multi-cylinder".

4. It is caused by a variety of reasons: the electrical lines of the vehicle are aging and the problem of leakage. There was an indirect failure in the ignition system of the engine. The ignition coil is damaged. The spark plug is damaged. After this problem occurs, the motor vehicle cannot drive, which will seriously affect the power output of the vehicle.

5. The causes of engine lack of cylinder fire can be divided into two categories: one: electronic control system failure, such as missing sensor signal or signal misalignation, control signal error or no signal output, spark plug or ignition coil damage leading to inability to ignition, fuel injector not inject oil and line failure, etc.

6. The reasons for the multi-cylinder fire of the engine are as follows: in terms of electrical wiring.Electrical circuit aging, leakage, etc., intermittent ignition failure. Ignition coil or spark plug failure, poor ignition or poor conduction. In terms of the line, loose, broken skin and iron, etc. In terms of oil routes.

Engine multi-cylinder fire?

The so-called engine failure refers to the engineOne or several cylinders do not work or do insufficient work, which is what we usually call "engine lack of cylinder". After the engine fire failure, there will be serious shaking, the engine power will be insufficient, the car will be weak to accelerate, and the fuel consumption will increase.

Partial fire failure means that the mixed gas does not burn completely in the cylinder; while complete failure means that the mixed gas does not burn in the cylinder.

Cylinder pulling is the phenomenon that the piston and piston ring are forcibly pulled out of obvious grooves and scratches during the process of engine operation due to poor lubrication or too small cooperation gap. Generally, excessive water temperature, poor oil lubrication, mismatching parts and other reasons will cause the engine to pull the cylinder.

It should be that the compression pressure is insufficient, and the metal has a characteristic when it is cool: thermal expansion and cold contraction. When the cylinder shrinks coldly, the gap between the piston and the cylinder liner is large, so the compression force is insufficient.When the car is started when it is cold, if it is difficult to start, it can be said that the compression is insufficient.

Chang'an Star multi-cylinder fire 3-cylinder 4-cylinder fire

I Electronic control system failure, such as missing sensor signal or misalignified, control signal error or no signal output, spark plug or point The fire coil is damaged and cannot be ignited, the fuel injector does not inject oil, and the line fails, etc.

Electrical circuit aging, leakage, etc., intermittent ignition failure; ignition coil or spark plug failure, poor ignition or poor conduction; in terms of lines, looseness, broken skin and iron, etc.; man-made operation reasons, such as carelessness or mistakes during maintenance: faults caused by touch, loose plug-in parts, etc.

Hello, clean the fuel injector and replace the spark plug [If there is a problem with the car, ask the car master.4S store professional technician, 10 minutes to solve.

The new Chang'an Star CHG gas fault three-cylinder fire. It is recommended to check whether there is a problem with the spark plug and ignition cylinder line of the car. The three-cylinder fire is mostly caused by such problems.

For the specific causes and elimination methods of multi-cylinder fire in automobile engines, please refer to the following analysis: The reasons for multi-cylinder fire in general automobile engines are as follows: ignition failure, need to check the ignition coil and high-pressure line. The ignition coil can't be repaired. If it is broken, it can only be replaced.

The fuel injector is damaged, and the fuel injector of three or four cylinders does not inject fuel or injects less fuel, resulting in the inability of the three or four cylinders to burn, and naturally there will be a fire. Replacing the fuel injector can be repaired.

EngineThe fault light is on, showing that the engine has a multi-cylinder fire

1. The specific situation analysis is as follows; sensor problems; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car If the engine data cannot be accurately obtained, the engine fault light will turn on at this time.

2. The engine fault light and three-cylinder fire failure caused by private refueling may be caused by the use of inappropriate fuel or additives.

3. I. Failure of the electronic control system, such as the sensor signal is missing or the signal is misalignified, the control signal is wrong or there is no signal output, the spark plug or ignition coil is damaged and the inability to ignite, the fuel injector does not inject oil and the line failure, etc.

4. For the specific causes and elimination methods of multi-cylinder fire of automobile engines, please refer to the following analysis: The reasons for multi-cylinder fire of general automobile engines are as follows: ignition failure, need to check the ignition coil and high-pressure line. The ignition coil can't be repaired. If it is broken, it can only be replaced.

What's wrong with the Skoda Mingrui 1.2t computer detection of 2/3 cylinder fire?

Reasons for reference only: sensor damage, poor contact or signal interruption; poor engine maintenance; poor quality of fuel and oil; insufficient combustion of mixed gas; spark plug failure, ignition coil failure; fuel pump failure, oil line blockage; air conditioning filter blockage.

Aging of electrical wiring, leakage, etc., intermittent ignition failure;Ignition coil or spark plug failure, poor ignition or poor conduction; in terms of lines, loose, broken skin and iron, etc. Man-made operation reasons, such as carelessness or mistakes during maintenance: faults caused by touching, loose plugs, etc.

The so-called engine fire refers to one or more cylinders of the engine that do not work or do insufficient work, which is what we usually call "engine cylinder deficiency". After the engine fire failure, there will be serious shaking, the engine power will be insufficient, the car will be weak to accelerate, and the fuel consumption will increase.

Use a car computer to detect, show what's going on with multi-cylinder fire

I Electronic control system failure, such as missing sensor signal or misaligned signal, control signal error orNo signal output, the spark plug or ignition coil is damaged and the ignition cannot be ignited, the fuel injector does not inject fuel, and the line fails, etc.

The specific analysis is as follows; sensor problem; the sensors mentioned here include water temperature, crankshaft position, air flow, intake temperature, oxygen sensor, etc. When these sensors are damaged, poor contact or the signal is interrupted, the ECU of the car cannot accurately obtain the engine data, and at this time it will Cause the engine fault light to turn on.

Circuit failure: spark plugs, cylinder wires, ignition coils, etc. are damaged, and it is easy to have missing cylinders.
