【Abstract】 This paper analyzes the deficiencies of accumulator type common-rail injection system. By improving the injector structure, the new-style of hydraulically intensified common-rail injection system realizes pilot injection and ideal injection rate model. After establishing the calculation model and through the numeral simulations, the injection characteristics of the common-rail injection system have been investigated. The experiment investigations prove that the numeral simulations are accurate. The new type of hydraulically intensified common-rail injection system can satisfy the requirements of future engines.更多还原
