Effects of ignition advance on combustion, fuel consumption and emission at 13b wankel engine

Abstract

In this study, the optimum advances for parameters such as specific fuelconsumption, emissions were investigated in ignition advances below 100 EA and above 100 EA.Cylinder pressure was measured for calculating the heat release rate. 13B MSP (Multi Side Port)single rotor and port fuel injection Wankel engine was used in the experiments. In this context,single rotor Wankel test engine was operated at 2000, 3000 and 4000 rpm engine speed, part loadsand λ = 1 condition. The optimum ignition advance is based on the value at which the maximumtorque is obtained. Thus, the effect of ignition advance was investigated on Wankel engine. As aresult, it is observed that ignition advance has a significant effect on emissions, in-cylinder pressureand fuel consumption in Wankel engine.
