近年来,直喷柴油机由于其良好的燃油经济性,在轿车方面的应用迅速增加:另一方面,由于废气排放法规的日趋严格,发动机制造商不得不开发喷油系统新技术,以减少NO_x、颗粒物及黑烟等的废气排放。我们开发了配有新型电控高压喷油泵的柴油机,这种4.2L直喷柴油机可以大大减少废气排放和提高动力性能,满足用户及社会的要求。
In recent years, direct injection diesel engines have rapidly increased their use in cars because of their good fuel economy. On the other hand, as exhaust emission regulations become more stringent, engine manufacturers have to develop new fuel injection system technologies to reduce NO x, Particulate matter and black smoke emission. We have developed a diesel engine with a new electronically controlled high-pressure injection pump. This 4.2L direct injection diesel engine can greatly reduce emissions and improve power performance to meet the needs of users and society.
