Abstract: The application of exhaust gas turbocharged technology improves the intake efficiency and power performance of electronic control gasoline engine, at the same time, it forces the relevant system of engine to make necessary changes in structure and function. In this paper, the differences of structure and function between natural aspirated engine and turbocharged engine in intake, exhaust, cooling, lubrication, PCV, EGR, EVAP and other relative systems are described, thus, it provides necessary guidance for the maintenance and repair of electronic control gasoline engine.
