摘　　要：整车动力性和经济性是一对相互矛盾的整车性能,如何在获得足够动力性的同时,能有最好的燃油经济性是整车匹配中需要解决的问题。随着汽车发动机电子燃油喷射技术的发展,为整车的动力性、经济性匹配提供了良好的条件,使整车匹配中可以根据设计要求,在一定范围内,通过调整发动机外特性和变速箱速比,使整车动力性和经济性达到最优。Vehicle power and economy is one conflicting vehicle performance. It is a problem that getting enough power and the best fuel economy at the same time to be solved in the vehicle matching. With the development of the automotive engine electronic fuel injection technology, good conditions for the vehicle＇s power, economy have become available and match the vehicle matching the design requirements, making the optimal vehicle power and economy by adjusting the engine outside characteristics and variable speed box speed ratio within a certain range.

关 键 词：整车动力性 经济性 整车匹配
