宝马新型四缸和六缸燃油分层直喷式汽油机

Stratified charge and direct injection 4-and 6-cylinder new gasoline engine of BMW

本文介绍的高精度喷油的新型发动机将作为重要的批量生产的机型投入应用。它们将对CO_2排放的进一步减少做出明显的贡献,同时还提供了宝马典型的动力性。它们所达到的油耗指标明显地低于燃油经济性也是相当不错的Valvetronic发动机,因而在这个功率级别的传统汽油机竞争场中占据着顶级地位。

This paper introduced that a new engine with high precision injection will put into operation as an important volume production model. It will make an obvious contribution for further reducing CO2 emission. Meanwhile it provided typical dynamic performance of BMW. Its fuel consumption is remarkably lower than the Valvetronic engine, which has considerable fuel economy. Therefore, the new gasoline engine ranked the top in the same power category of competition of traditional gasoline engine.
