New Advanced Technology to Improve Urban Environment

Gasoline direct injection (GDI) engines have become the development direction and goal of the engine technology. The engine with gasoline direct injection technology has become the main automotive manufacturers preferred power sets, and gasoline direct injection technology was applied to many cars a few years ago. In order to adapt to the development of new dynamic platform needs, in this paper, based on GDI engine, the design of the automatic stop system can control piston stop-position by consuming the surplus kinetic energy of GDI engine. This system does not need to add other components and only use the existing accessories of engine.
