Abstract
In this study, the optimum advances for parameters such as specific fuel
consumption, 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 loads
and λ = 1 condition. The optimum ignition advance is based on the value at which the maximum
torque is obtained. Thus, the effect of ignition advance was investigated on Wankel engine. As a
result, it is observed that ignition advance has a significant effect on emissions, in-cylinder pressure
and fuel consumption in Wankel engine.

Abstract
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.
