Ordinary diesel engine camshaft is driven by means

Ordinary diesel engine camshaft is driven by means of high-pressure pump diesel fuel delivered to each cylinder chamber. This approach to oil changes with the engine speed changes, the optimum amount of oil can not do all kinds of speed. And now more and more widely used in electronic control common rail diesel injection system can better solve this problem. Common rail injection fuel system from the high-pressure pump, public automatic fuel dispenser supply tubing, fuel injectors, electronic control unit (ECU) and a number of pipeline pressure sensors, the system each injector through their high-pressure tubing and public supply tube connected to the public for the pipeline for injector has played the role of hydraulic accumulator. When working, high-pressure pump to the high pressure fuel delivery to the public for the pipeline, high pressure pumps, pressure sensors and ECU composed of closed-loop operation.
