Abstract

After most CO₂ is removed from exhaust gas by aqueous KOH in the CO₂ absorber, the exhaust gas is re-circulated and mixed with a fresh oxygen charge to constitute a CCDE (closed cycle diesel engine) system. This study then improved the combustion and emissions of the diesel engine in the CCDE system using diesel fuel as main fuel with ethanol or gasoline of various energy share ratios inducted into the inlet port. Isothermal lines and velocity distributions in the engine cylinder from the numerical results are used to explain the measured emission results from the diesel engine in the CCDE system with port-inducted fuel. The CCDE system effectively decreases smoke, NO_x, and CO₂ before the CO₂ absorber using port-inducting ethanol or gasoline. In addition, the experimental results are consistent with the numerical results for the operating engine.
