Abstract :
In this paper, the energy flow characteristics of turbo charging system were studied on a gasoline direct injection engine. Based on engine dyno tests, various kinds of intake and exhaust parameters were measured under mapping characteristics, and then the maps of turbo charging system energy flows were acquired by combining energy balance equations. On this basis, the exhaust energy recovery efficiency and energy flow characteristics of turbo charging system were analyzed. Exhaust energy recovery efficiency of turbo charging system mainly depends on the pressure ratio of intake gas, in the whole gasoline engine operating conditions area, exhaust energy recovery efficiency of turbocharger is between 2.5% and 7.5%, and the larger value appears in gasoline engine high load operating conditions.
