4000系列柴油机共轨式喷油系统首次成批应用在此功率等级柴油机上,它采用了一种全新发展的技术。此喷油系统是与德国发动机和涡轮机联合股份公司(MTU)共同开发的。利用这种新型喷油系统成功地克服了常规喷油系统的先天缺陷。从而有可能自由选定万有特性中的喷油正时、喷油量和喷油压力。另外,液力操纵的喷油嘴针阀关闭机构可实现喷油的迅速结束。用较少的代价就可实现预喷射。 4000 series diesel common rail injection system for the first time in batches for this power grade diesel engine, which uses a newly developed technology. The fuel injection system was developed with the German joint venture engine and turbine company (MTU). The new injection system successfully overcomes the inherent shortcomings of conventional injection systems. It is therefore possible to freely select the injection timing, fuel injection amount, and injection pressure in the all-inclusive characteristics. In addition, the hydraulically operated injector needle shut-off mechanism allows for rapid end of injection. Pre-injection can be achieved with less cost.
