Car engine does not catch fire 5, car engine does not catch fire

Hello! If you can't catch fire, you check it out.

1. Check the valve clearance, if it is not right, you need to adjust it, if your car is DHOC, you have some annoyance. Valve gaskets are not easy to find.

2. Check the spark plug to see if the model is correct and whether the electrode gap is in between. Observing the combustion condition at the same time helps to judge the adjustment of the carburetor. It is highly recommended to choose high-quality imported spark plugs with correct calorific value and beware of counterfeiting.

3. Measure the compression ratio, if there is no cylinder pressure gauge, cover the spark plug hole with a thin piece of paper, if the paper piece is sucked more violently when starting, even if it is okay. If you pay attention to it, you can install a homemade air valve on the spark plug hole and use a pump to check for air leakage.

4. Oil circuit inspection. It is better to remove the fuel tank and use a container to force the oil to be fed, because there is a possibility that the negative pressure tank switch will fail. In addition, look at the interface glue between the carburetor and the engine for air leakage.

Generally speaking, gasoline vehicles can ignite as long as there is oil, electricity, and cylinder pressure.

According to what you said, it is likely that the oil supply system is faulty, find a master and let him see.

After returning and replacing one, there is fire, electricity, and cylinder pressure after installation] That is the oil circuit problem! The electronic oil pump is broken!

Summary. Hello Honored for your problem: The reason why your car won't catch fire could be an electrical or electronic fault in the first place. Blown fuses, short circuits of high-voltage coils, short circuits of low-voltage circuits, falling off of the center ignition wire, leakage of the distributor head, and damage to the spark plug will cause failure to ignite.

Hello Orange Ash, the reason why your problem car does not catch fire may first of all be imitation rental circuit or electronic failure. Fuse blowing, high-voltage coil short circuit, low-voltage circuit short circuit, center ignition wire falling off, distributor leakage, spark plug damage round belt, etc. will cause no ignition.

At first, it was also a line problem.

Hello, if you can't catch fire, it's generally a problem with the line.

There are also oil circuit failures. The stalling caused by the oil circuit trembling obstacle often has the symptoms of engine weakness, and the refueling pedal is pure and pure. The parts that may occur in the oil circuit failure are: oil pump failure, oil circuit failure, oil filter blockage, and nozzle damage.

The battery also needs to be checked.

Reason 1 may be that there is a problem with the oil supply system of the automobile engine, such as the oil circuit is blocked due to low pressure, the oil supply pipe of the engine is loose and leaking, the technical condition of the injector is not good, and the timing angle of the injector is wrong. 2 It is possible that the starting device of the engine is faulty, such as the power supply of the engine starting or the contact of the electromagnetic switch, the clutch of the engine of the Tambu car is slipped, etc. 3. The cylinder gasket of the cylinder in the automobile engine is damaged, resulting in cylinder leakage, and the engine cylinder is not tightly closed and leaking, which will lead to insufficient pressure in the engine cylinder, which will affect the start of the automobile engine.

4. The filter element of the air filter in the cylinder of the automobile engine is blocked, resulting in insufficient side flutter of the air intake of the cylinder. It will also be difficult to set the car engine on fire.

Reasons why the car engine does not catch fire: battery failure, spark plug problems, oil circuit or fuel injector failure, cylinder pressure problems, throttle carbon deposits, etc.

1. The car can't catch fire, the first thing that comes to mind is that the battery is out of power, you can press the horn to see if there is any sound, if it is silent, the battery is indeed out of power, or the battery power may be too low.

2. If the engine speed is normal, check the spark plug ignition device, the spark plug is like the heart in the human body, the heart failure person can not live, the spark plug has a problem, and the vehicle can not start;

3. The spark plug spark is normal, check the oil circuit and fuel injector, if it is like some vehicles that have been very old for a long time, the line may be aging, and the oil circuit or fuel injector will fail to start;

If the oil circuit is normal, check the cylinder pressure, if the cylinder is flooded, even if there is no problem with the engine itself, it will not be able to run if it is noisy, so it can discharge too much gasoline first;

There are several reasons why the engine does not ignite:1. The battery is insufficient, or there is no power, for the diagnosis of such faults that the engine cannot start, the battery should be tested first. It is necessary to find out whether the engine does not start because the battery is insufficient, and the battery needs to be charged if it is insufficient.

2. Engine starting system failure. In the case of faults such as engine failure to start, the first thing to do is to check the circuitry in the engine starting system. From the perspective of the most basic composition, the circuit of the starting system generally includes the following basic parts, that is, the battery, the starting motor and the cable connecting these parts.

Of course, in addition, the ignition switch is not simplified, the starter relay or solenoid coil, and the vehicle anti-theft system are also important parts of the starting system. If the starting system is damaged, you need to go to the 4S shop for repair.

3. Engine ignition system failure. In early ignition systems, the ignition coil could be easily removed and a spark detector could be used to detect whether the spark was normal. Ignition system failures can be used to clean up deposits or replace spark plugs.

The above are the reasons why the engine does not ignite, you can check the air call one by one.

There are many times in life that the car does not catch fire, what is the reason, the rabbit takes you to understand the reason, generally the car does not catch fire and do not need to worry, sometimes it may be a problem during operation, the most common is that the steering wheel is locked.

The engine and battery voltage are not enough, the cylinder pressure is not enough, the oil explosion pressure is not enough, there is a problem with the ignition module, and the anti-theft is locked.

There are many reasons, first look at oil and electricity.

There are many reasons! The battery is dead!
