Hot cars in Fista don't burn well.

It's not necessarily the reason that hot cars don't strike easily. Most new cars have too little or no clearance when the valve is cold, which leads to the tight valve closure in hot state and is not easy to strike a fire.

Reason: 1, because there are too many carbon deposits in the throttle, idle motor, air intake and combustion chamber.

2. There is a slight leakage from the fuel nozzle, which causes the fuel to leak into the combustion chamber for a period of time after the vehicle is turned off, which leads to the excessive mixture when starting again, and finally leads to the difficulty in starting.

3. The activated carbon canister is damaged.

The correct way to warm up the car should be to go on the road 30 seconds after starting to 1 minute. But don't drive at high speed at this time, keep low speed, and the engine speed should not exceed 3000~3500 rpm. Generally keep 2000 rpm. Otherwise, the severe wear and tear suffered by the engine and gearbox is irreparable. After the engine temperature rises to the normal working temperature, the "personal habit" driving mode can be restored.
