摘要
建立了某涡轮增压柴油机一维工作过程模型并经试验验证;用该模型研究了排气背压的升高对涡轮增压柴油机输出功率的影响,并通过增压系统的重新匹配和设计改造,探讨了两种改善发动机环境背压适应性的方案。
A 1-D calculation model for studying the working process of a certain turbocharged engine was established and verified by tests. The influence of high exhaust back pressure on the engine power was re- searched. To improve the adaption of engine to different back pressure, the turboeharger system was re- matched and redesigned in two different ways, which are discussed.
