摘　　要：为研究燃烧室形状对柴油机燃烧和排放性能的影响,应用大型通用CFD软件STAR-CD程序对3种不同形状的燃烧室内燃烧过程进行了多维数值模拟计算,研究了不同的燃烧室形状对缸内气流运动以及缸内燃烧温度和排放的影响,并通过实验验证了计算模型的正确性。In order to study the effects of combustion chamber shape on combustion and emission characteristics in a diesel engine, large universal CFD software STAR-CD is used to simulate the combustion processes in three types of combustion chambers of diesel engines. The effects of combustion chamber shape on in-cylinder air motion, temperature field and exhaust emissions are researched. Through compared with experimental resuits, calculation models are proved to be of validity.
