The Chevrolet Lechi hot car does not catch fire, and it can catch fire after half an hour of cooling

1. Cause analysis:

Many of the reasons why you can't ignite are caused by improper operation, such as running out of oil, running out of electricity, and having the wrong gear, and these situations are quite common.

1.Out of gas. I went out to rescue a car before, but the fuel gauge showed that it was below the red line, so naturally it could not catch fire.

2.The battery is dead. It may be due to the loss of power caused by the headlights not turned off for a long time or the battery life expires, and it is generally recommended to replace the battery in time after three years.

In addition, the installation of xenon headlights, high-power audio, etc. are also the causes of vehicle circuit failures. The situation of the vehicle without power is easy to check, just press the horn to know.

3.The gear is wrong. When the automatic transmission car starts, the gear must be placed on the P or N gear, if it is placed on the R or D gear, it will not ignite. There are also some manual transmission cars that will not catch fire if you don't step on the clutch.

Second, what to do and how to solve the reason why the car cannot catch fire.

Reasons for vehicle use: improper oil, no antifreeze, excessive carbon deposit.

In addition to the reasons for improper human operation, there may also be motor failure, or oil pump oil supply, fuel injector problems, sensor failure, etc., encountering these more complex situations, need to be dealt with by professionals. However, pay more attention to the following items when using a car to avoid these complex situations.

1. Oil problem. When I was repairing a car, I found that there was water and mud in the fuel tank after dismantling it, and it was impossible to use such oil to keep the car from breaking. Therefore, it is reminded that you must go to a regular gas station to refuel, and you can bring a gauze wrapped in the muzzle of the gas gun to filter impurities.

2. No antifreeze added. Some car owners add water or inferior antifreeze to the car, resulting in a particularly cold winter, causing the entire waterway to be frozen, the engine to be frozen and cracked, resulting in the car water pump can not operate, can not catch fire, and injure other parts of the engine.

3. Too much carbon accumulation in the vehicle will also cause the vehicle to not catch fire, and the solution is to reduce the carbon deposit by running at high speed frequently. In addition, there is a small trick for not ignition, before starting the ignition, first screw the key to the ON switch, and then turn it back, and then turn on the strat switch to ignition, let the computer run to calculate the water temperature and the appropriate air intake, and the ignition will be smoother.

Hello check the oil pressure, ignition coil, spark plug,

There are five main reasons why the hot car cannot catch fire: 1. The injector is dripping. 2. The solenoid valve of the carbon canister is damaged and the fuel quality is damaged. 4. Inlet air temperature sensor. 5. Engine carbon deposits.

1. Injector dripping. It is normal for the injector to inject fuel, but if there is a drip, it is an additional fuel supply, so the more serious the injector drip, the thicker the mixture, which will cause the hot car to start poorly. 2. The solenoid valve of the carbon canister is damaged.

If the carbon canister has been replenishing oil and gas to the inlet tract, it will cause the mixed Chunkai to be too concentrated, resulting in difficulty in starting. 3. Fuel quality. If the fuel itself is easy to volatilize, it is easy to form a higher evaporation pressure in the oil rail, and when this pressure is greater than the pressure of the fuel supply system, it will form air resistance, resulting in too thin oil vapor from the fuel injector, which will lead to difficulty in starting.

4. Inlet air temperature sensor. Inlet air temperature sensors are similar to water temperature sensors in that they both correct the amount of fuel injected, but the difference is that if the water temperature sensor fails, it will make it difficult to start cold. A faulty intake air temperature sensor can make it difficult to start a hot car.

5. Engine carbon deposits. Engine carbon deposition is already a big problem, carbon deposition has a strong adsorption effect on the old oil of the steam strip, if the intake valve, the valve and the piston and other carbon deposits, it is easy to adsorb some fuel, resulting in the mixture is too thin, which affects the start, this situation will also appear in the cold car start.

Of course, in addition to these common factors, there are many reasons why the hot car is not good to start, and it is not a car owner who can solve it, if the hot car is not good to start, it is recommended that the owner go to a professional repair shop or 4S shop for maintenance.

1. Your inability to hit the phenomenon may be mainly caused by excessive carbon deposits in the idle motor, air intake tract, intake valve and combustion chamber.

2. Because of the excessive carbon deposition and dirt in the air intake, the cross-sectional area of the air passage changes, resulting in the mixture being too thick or too thin, making the combustion abnormal or the engine shaking or even unable to start after starting. Or because there is a problem with the fuel injector, there is leakage or too much carbon, resulting in the mixture being too thin during start-up, which makes it difficult to start.

3. If the carbon canister or carbon canister solenoid valve fails, it will also cause it to be difficult to start.

Reasons: 1. Because of excessive carbon accumulation in the throttle, idle motor, intake duct and combustion chamber.

2. There is a slight leakage phenomenon in the fuel injector, which causes the fuel to leak into the combustion chamber for a period of time after the vehicle is turned off, resulting in the mixture being too thick when starting again, and finally causing it to be difficult to start.

3. The activated carbon tank is damaged.

It is recommended to check the water temperature sensor, if the water temperature sensor signal is not good, it will cause the phenomenon that the cold car is not easy to start. Secondly, it is necessary to check the carbon deposits in the air intake system, if the vehicle is driving at low speed or low temperature for a long time, and when driving for a short distance, there will be some colloidal carbon deposits in the valve seat and throttle accessories, so it will also cause the phenomenon that it is not easy to start.

It is normal for the car to be ignited twice in Dongzhou Zen for a long time.

You can do a tour of pure maintenance, which can be better miracles.
