When the temperature rises, the misfire and unsteady combustion decrease.The low temperature causes ignition delay increase. 提高冷却液温度对于消除起动过程首循环燃烧状态的不稳定性具有较明显的作用。
The fans are controlled either with a thermostatic switch or by the engine computer, and they turn on when the temperature of the coolant goes above a set point. 风扇要么由恒温开关控制，要么由发动机芯片控制，当冷却液温度高于设定值时，风扇开。
