摘 要：Medium and heavy duty commercial vehicles are playing important roles to support the present nation building and logistics in ***,emissions regulations as stringent as those for passenger cars are going to be implemented *** meet the regulations,it will be necessary to use complicated aftertreatment systems,which can cause disadvantages for the system including increased cost and reduced fuel *** such an environment,DENSO,under the development policy Diesel Revolution,has been developing attractive engine management systems with an aim of simplifying the total engine management system and improve fuel efficiency,which is the exact opposite to the general *** accomplish this,DENSO worked to build a highly-sophisticated injection system which is capable of improving spray quality and controlling variation in injection quantity,which is an important factor,under the concept of minimizing engine-out emissions to reduce requirement for aftertreatment *** injection pressure and adding system control to reduce variation,has enabled the DENSO engine management system to respond to Green ＆ Eco which will be introduced in global scale in the future.
