用油流法和激光多普勒技术，对直喷式柴油机紊流型燃烧室内的宏观壁面流谱和 燃烧室内紊流强度进行了观测研究；分析论证了紊流型燃烧室比普通ω型燃烧室具有 更强的紊流强度．
By using the oil flow method and laser Doppler technique, the macroscopic wall flow spectrum and the turbulent intensity in the combustion chamber of a direct injection diesel engine turbulent combustion chamber were observed and analyzed. The turbulent combustion chamber was analyzed and compared with the ordinary ω type combustion Room has a stronger turbulence intensity.
