About common rail injector system
Common Rail technology refers to a closed-loop system composed of high-pressure oil pump, pressure sensor and electronic control unit (ECU) that completely separates the generation of injection pressure and the injection process from each other. It is a high-pressure oil pump to deliver high-pressure fuel to the public oil supply pipe, through the oil pressure in the public oil supply pipe to achieve precise control, so that the pressure of the high-pressure oil pipe and the engine speed five off, can greatly reduce the diesel engine oil supply pressure with the engine speed change degree. The high-pressure common rail injection system is mainly composed of low-pressure fuel supply system, high-pressure fuel supply system, fuel injection system and electronic control management system.
The common rail system refers to a closed-loop system composed of high-pressure oil pump, pressure sensor and electronic control unit (ECU), which completely separates the generation of injection pressure and the injection process from each other, which is completely different from the previous diesel injection system driven by camshafts. It is a high-pressure oil pump to deliver high-pressure fuel to the oil rail, through the oil pressure in the rail to achieve precise control, so that the high-pressure oil pipe pressure is independent of the engine speed, can greatly reduce the degree of diesel engine oil supply pressure with the engine speed change.
The diesel high-pressure common rail injection system consists of a hydraulic system and an electronic control system. Among them, the hydraulic system is divided into low-pressure hydraulic system and high-pressure hydraulic system. The low-pressure hydraulic system includes a fuel tank, a fuel transfer pump, a fuel filter and a low-pressure oil line; The high-pressure hydraulic system includes high-pressure pump, high-pressure oil rail, injector and high-pressure oil pipe; Electronic Diesel Control (EDC) includes sensors, Electronic Control Unit (ECU), actuators (including injectors with solenoid valves, pressure control valves, glow plug control units, booster pressure regulators, exhaust gas circulation regulators, throttle valves, etc.) and wiring harnesses.
