산소과급 대형디젤기관에서 고압루트방식 Cooled-EGR정용에 따른 성능 및 배출가스 특성에 관한 실험적 연구

This research was carried on an 8100cc turbo-charged heavy duty diesel in the application of a cooled-EGR. Exhaust and intake manifold were modified and an electronically controlled EGR was installed in order to investigate engine performance and exhausted emission characteristics. High pressure route was designed in the compact form on the purpose of practicability in this cooled-EGR system. which constitutes a venturi tube to maintain pressure difference between exhaust manifold and compressor. an EGR cooler. an EGR valve and a solenoid valve.
