| Abstract: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 researched. To improve the adaption of engine to different back pressure, the turbocharger system was re-matched and redesigned in two different ways, which are discussed. |
