近年来，由于直喷式柴油机的油耗低，所以在小轿车上的装用量已经迅速增加起来。另一方面，排气排放控制也已经一年一年地严格起来。各发动机制造商不得不开发降低排气排放物（如ＮＯＸ、颗粒物及黑烟）的喷射系统新技术。我们已经开发出一种使用电控高压喷油泵的新发动机。这种新的排量４２Ｌ直喷式柴油机，可以实现大幅度降低排气排放和高功率。符合用户和社会的期望 In recent years, due to the low fuel consumption of direct injection diesel engines, the installed capacity on the cars has rapidly increased. On the other hand, exhaust emission control has also been rigorous year by year. Engine manufacturers have had to develop new injection system technologies that reduce emissions (such as NOx, particulates and black smoke). We have developed a new engine that uses an electronically controlled high pressure injection pump. This new displacement 4  2L direct injection diesel engine, can achieve a substantial reduction of exhaust emissions and high power. Meet the user and the community’s expectations
