【Abstract】 The pilot injection is realized in medium pressure common rail electronic diesel injection system on the basis of injector structure modification. A model for hydraulic calculation is built and the injection characteristics of the common-rail system are simulated. The experiment proves the correctness of numeral simulations.更多还原
