综合介绍了近几年来大功率直喷式柴油机技术发展现状 ,研究了这些新技术对缸内紊流的作用与影响 ,并根据缸内紊流的产生及其特性指出 ,大功率直喷式柴油机应以高压喷射为主 ,利用适当的缸内紊流运动并结合合理的燃烧室结构是获得优越性能的关键。 This paper introduces the development of high power direct injection diesel engine technology in recent years, and studies the function and influence of these new technologies on the cylinder turbulence. According to the generation of turbulence in the cylinder and its characteristics, Should be based on high-pressure jet, the use of appropriate turbulent in-cylinder movement combined with a reasonable structure of the combustion chamber is the key to superior performance.
