A strategy based on motion planning is proposed for airpath control of turbocharged diesel engines equipped with exhaust gas recirculation. The objective is to manage the air and burned gas masses in the cylinder. The model considered uses simple balance equations for the intake manifold. The fully actuated dynamics are easily inverted, yielding straightforward open-loop control laws. This appr...
In the present study, a computational fluid dynamics (CFD) method have been utilized to investigate the effects of exhaust gas recirculation (EGR) and initial charge pressure by means of using a supercharger on the emissions and performance of a SI engine. This engine is fueled separately by gasoline and two potential alternative fuels, hydrogen and ethanol. The results of simulation are compar...
Nitrogen oxides (NOx) contribute to a wide range of environmental effects including the formation of acid rain and destroy ozone layer. In-cylinder high temperature flame and high oxygen concentration are the parameters which affect the NOx emissions. The EGR system is a very effective way for reducing NOx emission from a diesel engine (via reduction of these parameters), particularly at the...
