Toyota Prius hybrid vehicles as the worlds first mass production, has experienced the first generation, second generation and three generation of development. As one of the source engine based on inheriting the traditional engine structure and control of the advanced,using a new type of combustion chamber structure, high expansion ratio Atkinson, VVT-i system and new technology to reduce the engine speed, the power performance, fuel has high economic and emission clean. In this paper, through the analysis of the new Prius engine technol
