The EFI vehicle corrects the fuel injection quantity according to the intake temperature and water temperature, so the fuel injection quantity is large when the cold vehicle starts, and the engine returns to normal state when it reaches the normal working temperature.

Because of the low temperature, the atomization of oil-gas mixture is not as uniform as that at high temperature, and the fuel injection ratio is relatively high.
