Application of Model Based Control to the Mass Production Diesel Engine Using Dual EGR System

Abstract

In global warming issue, reduction of Carbon dioxide (CO₂) emission is needed for passenger vehicle. Our company developed a new generation 1.6L diesel engine as a part of technologies for high driving performance and good fuel economy. The dual Exhaust Gas Recirculation (EGR) system for achieving both good fuel economy and low emission are introduced in addition to our previous diesel engine, and met Euro5 emission regulation, and achieved 14.5 % reduction of CO₂ emission (94 g/km in NEDC mode). In this paper, the model based control for the dual EGR system using an intake throttle will be described.
