摘要

Demand for diesel-powered passenger cars has risen in the European market compared with gasoline-powered cars. However, exhaust emission regulations are being progressively tightened to protect the global environment, with EURO4 regulations taking effect in 2006. Nissan Motor Company has developed a new 2.2-L direct-injection (DI) diesel engine complying with EUEO4 regulations for the European SUV market. This paper describes the developed technologies, the basic combustion system, DPF system and control technologies, including cooperativing control between a VNT and EGR, and highly accurate lambda control.
