13B Wankel Motorunda Ateşleme Avansının Yanma, Yakıt Tüketimi ve Emisyona Etkileri

Bu çalışmada, optimum avans, 10 derece EMA altı ve 10 derece EMA üstü avanslarda özgül yakıt tüketimi, emisyonlar, silindir içi basınç ve ısı salımı oranları gibi parametreler incelenmiştir. Motor olarak deneyde 13B-MSP tek rotorlu ve manifolda püskürtmeli bir Wankel motor kullanılmıştır. Bu kapsamda, tek rotorlu Wankel deney motoru 2000, 3000 ve 4000 dev/dak motor hızında, kısmi yüklerde ve λ=1 koşulunda çalıştırılmıştır. Optimum ateşleme avansı maksimum momentin elde edildiği değer baz alınmıştır. Böylece, ateşleme avansının Wankel motordaki etkisi incelenmiştir. Sonuç olarak ateşleme avansının Wankel motorda emisyonlar, silindir içi basınç ve yakıt tüketimi üzerinde büyük bir etkiye sahip olduğu gözlenmiştir.

EFFECTS OF IGNITION ADVANCE ON COMBUSTION, FUEL CONSUMPTION AND EMISSION AT 13B WANKEL ENGINE

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.
