日本轿车制造企业希望进一步提高汽油机引擎的效率和功率,以使常规动力的汽车能够与电动车和环保动力车竞争。预计在2017年末,日本马自达公司将为其现有的发动机增加可变排量装置和中度混合动力系统。可变排量技术就是根据汽车动力的需求,实时决定发动机的有效排量,这种技术将被应用于马自达CX-5运动型多用途车等安装了较大引擎的车型。中度混合动力系统是采用一个小型的电动机辅助汽油机
Japanese car manufacturers hope to further improve the efficiency and power of gasoline engines so that conventional power cars can compete with electric cars and eco-cars. It is estimated that in the end of 2017, Japan’s Mazda will add variable displacement units and medium-sized hybrid systems to its existing engines. Variable displacement technology is based on the demand for automotive power, real-time decision of the engine’s effective displacement, this technology will be applied to the Mazda CX-5 sport utility vehicles and other larger engines installed models. The moderate hybrid system uses a small motor-assisted gasoline engine
