Abstract
Diesel-powered vehicles need to cope with diversified fuel quality and environment of use to achieve sales expansion in the world. Therefore, the total engine management system which integrates three technologies- the injection system components provided with fuel-robust structure, the control system which underpins them to assure optimum combustion, and the aftertreatment system which is capable of offering high conversion ratio under diversified cruise conditions and environments as well as controlling lowered fuel efficiency- has been developed by authors.
