Tigers in Jiangling can't catch fire. The computer reported high rail pressure. As soon as it catches fire, it will turn off when it is refueled.

Hello, dear, there are the following reasons, battery problems. If this is the reason, the owner can judge whether the horn is ringing, the horn sound is obviously weaker than usual, or it is not ringing, so that the battery can be judged to be insufficient.

2. The oil-gas mixing ratio is not allowed. It exists in open-loop and closed-loop control. If the automobile computer makes a mistake, it will make a mistake in controlling the oil-gas mixing and ignition time through the actuator, thus reducing the power output of the automobile, causing jitter and causing the automobile to catch fire.

3. The power supply voltage of the ignition system is unstable. The reason is that the injector is too dirty and the carbon canister solenoid valve is damaged.

4. The fuel injector is leaking. The fuel injection of the injector is normal, but the oil dripping is extra fuel, so the more serious the oil dripping from the injector, the thicker the mixture will be, which makes it difficult to start the hot car.

5. Engine carbon deposit. 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.

6. 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.
