Is it normal for Cruze engine to be hot for a while?

It may be the following reasons that the hot car is not easy to catch fire after flameout: 1, the injector drips water; 2. The carbon canister solenoid valve is damaged; 3. Poor fuel quality; 4. The air temperature sensor is damaged; 5. Engine carbon deposit.

Details are as follows:

1, syringe dripping

It is normal for the fuel injector to inject fuel, but it leaks excess fuel, so the more serious the leakage, the thicker the mixture will be, which makes it difficult to start the hot car.

2. The carbon canister solenoid valve is damaged.

The fuel atomization of the hot car itself is normal, and there is no need to replenish oil and gas. If the carbon tank constantly replenishes oil and gas to the air inlet, the mixture will be too rich, which will make it difficult to start.

3. Poor fuel quality

After the hot car turned off for a period of time, the temperature in the engine compartment was still quite high. If the fuel itself is volatile, it is easy to form a higher evaporation pressure in the fuel rail. When this pressure is greater than the pressure of the oil supply system, air resistance will be formed, which will cause the oil vapor sprayed by the oil nozzle to be too thin and difficult to start.

4. The air temperature sensor is damaged

The air temperature sensor is similar to the water temperature sensor, and its function is to correct the fuel injection quantity, but the difference is that if the water temperature sensor fails, it will lead to difficult cold start; The failure of the temperature sensor will make it difficult to start the hot car.

5, engine carbon deposition

The problem of engine carbon deposition has a long history, and carbon deposition has a strong adsorption effect on gasoline. If there is a large amount of carbon deposit on the intake valve, throttle valve and piston, it is easy to absorb part of the fuel, which will lead to the mixture being too thin, thus affecting the start-up. This will also happen when the cold car starts.
