2-13 冷起动阀和温度时间开关 综上所述得知,在发动机冷起动的过程中,补充空气调节器使补充空气通道全开,供给发动机所需的空气量;同时暖机调节器使其控制压力在最低位置,使燃油计量分配器向发动机供给较多的油量,以保证发动机的低温起动和起动后能以快怠速迅速暖机,从而改善发动机的冷起动性能。但是,在严寒地区的低温条件下起动时,由于燃油的雾 2-13 Cold Start Valve and Temperature Time Switch As mentioned above, during the cold start of the engine, the supplementary air regulator fully opens the supplementary air passage to supply the air volume required by the engine. At the same time, the warm-up regulator The control pressure in the lowest position, so that the fuel metering dispenser to the engine to provide more fuel to ensure that the engine cold start and start quickly warm-fast idle speed, thereby improving the engine’s cold start performance. However, due to the fog of fuel when starting at low temperatures in cold regions
