2. Warm up the car at idle speed at 65,438+05 minutes in the morning is not only harmful to the engine but also pollutes the environment, unless it is clearly stipulated in the user manual (for example, the diesel version of Great Wall Motor Haval clearly requires that the warm-up time is 2 minutes, but it is not required to watch C50). Generally, EFI engines are designed for cold cars with high idle speed, and the speed is generally 65,438+0,200 seconds or more. Generally, it is recommended that the hot car be preheated in situ for no more than 2 minutes, and the hot car process can be automatically completed after driving for 3 kilometers.
