卡特D10R型推土机采用3412E型高压共轨式柴油机,柴油机HEUI型喷油器的喷油正时和喷射压力由柴油机控制器(ECM)根据柴油机曲轴转角、柴油机温度、涡轮增压器输出压力、负荷等进行控制。当活塞接近上止点时,控制器(ECM)向喷油器电磁阀发出控制信号,电磁阀将喷油器喷油孔打开,开始喷油。喷油器的喷射压力由高压机油泵输至高压机油共轨管的压力控制,该压
Carter D10R bulldozer with 3412E high-pressure common rail diesel engine, diesel engine HEUI injector injection timing and injection pressure by the diesel engine controller (ECM) based on the crankshaft angle of the diesel engine, the temperature of the diesel engine, turbocharger output pressure, load Such as control. When the piston approaches TDC, the controller (ECM) sends a control signal to the injector solenoid valve, which opens the injector orifice and begins to inject fuel. The injection pressure of the injector is controlled by the pressure of the high-pressure oil pump to the high-pressure oil common rail. The pressure
