Evaluation of exhaust gas recirculation techniques on a high-speed direct injection diesel engine using first law analysis

Abstract:

The effects of different EGR strategies on engine efficiency and the resulting energy flows at two speed/load conditions (1500 rpm/6.8 bar nIMEP and 1750 rpm/13.5 bar nIMEP) were studied using a first law analysis approach. The EGR strategies tested were: cooled high-pressure EGR (baseline), the application of EGR with the swirl flap closed and the use of EGR under constant λ conditions. The closed swirl flap EGR strategy reduced brake efficiency under high load conditions and increased heat ...
