What does car hot start mean?
1 Answers
Car hot start refers to restarting the engine after it has been turned off, while the engine temperature is still within the normal operating range, and the oil on the engine's friction surfaces has not yet drained away, with the oil film still present. The precautions for car hot start are: 1. Conduct a thorough inspection before hot starting, including checks on window glass, body assembly, tires, and the trunk; 2. Regularly clean the battery and replenish the battery electrolyte. The reasons for difficulty in car hot start are: 1. High engine temperature, where residual heat continues to warm the fuel lines, increasing fuel pressure in the fuel pipes; 2. Fuel system pressure loss, causing severe gasoline evaporation; 3. Carbon buildup in the throttle or low battery voltage.
