摘　　要：为了改进柴油机技术、提升柴油机性能,首先对某新型涡轮增压柴油机进行总体设计,进行热力和外特性计算及主要零部件设计,得到柴油机的基本结构参数。随后分别进行曲轴和连杆设计,并根据计算结果进行零件强度和刚度校核。校核结果表明设计符合要求,该新型涡轮增压柴油机的热效率更高,扭矩和功率与非增压柴油机相比都有所提高。In order to improve the technologies and performance of diesel engine, it presents the overall design of a new turbocharged diesel engine, calculates the thermal dynamics and external characteristics, obtains basic structure parameters. Then it designs the crankshaft and the connecting rod, analyzes the strength and stiffness of these parts. The result meets the requirement. This new turbocharged engine performs better than a non-turbocharged one in thermal efficiency, torque and power.
