소형디젤엔진용 전자식 EGR밸브 개발과 차량적용에 관한 연구

Global demands related to vehicle emission from environmental protection organizations and governments have been increasing, resulting in the introduction of more severe emission regulation. In order to analyze the characteristics of Electric EGR valve, the EGR simulator was designed to control the now rate, pressure difference and temperature of EGR route and now rate of heat exchanger. In this paper shows the research of engine performance during EGR for the application of Electric EGR to SMART car and engine. It was installed a 3-cylinder turbo-charger light duty diesel engine with an electric EGR valve.
