Buji Ateşlemeli Motorlarda Kullanılan n-Propanol ve izo-Propanol/Benzin Yakıt Karışımlarının Performans ve Emisyonlara Etkisi

Bu çalışmada buji ateşlemeli bir motorda n-propanol ve izo-propanol alkolleri kullanımının motor performans veemisyonlarına etkisi incelenmiştir. Deneylerde B100 (%100 benzin) 20 n-pro (%80 benzin+%20 n-propanol) ve20 izo-pro (%80 benzin+%20 izo-propanol) yakıt karışımları kullanılmıştır. Deneyler motor tam gaz konumunda,altı farklı motor devrinde (yükünde) (1500-4000 d/dk) yapılmıştır. Performans sonuçlarına göre, izo-propanolalkolü ilavesi ile motor momentinde ve motor gücünde önemli bir değişiklik görülmemiştir. Fakat özgül yakıttüketimi izo-propanol alkol kullanılmasıyla %2,23 oranında artmıştır. Emisyon sonuçlarına göre, HC ve COemisyonları alkol ilavesi ile birlikte sırası ile yaklaşık %10,52 ve %4,41 azalmıştır. Öte yandan CO2 ve NOXemisyonları sırası ile yaklaşık %17,38 ve %15,24 oranında artmıştır.

The Effect on Performance and Emissions the Spark Ignition Engines of n-propanol and iso-propanol/Gasoline Fuel Blends

In this study, the effect of the usage of n-propanol and iso-propanol alcohols in a spark ignition engine on engine performance and emissions is investigated. Fuel mixtures of B100 (100% gasoline), 20 n-pro (80% gasoline + 20% n-propanol) and 20 iso-pro (80% gasoline + 20% iso-propanol) are used in the experiments. The tests are carried out at six different engine speeds (1500-4000 d/min) in full-throttle position. The results show that the addition of iso-propanol alcohol resulted in a 2.23% increase in the specific fuel consumption without significant changes in motor momentum and power. In the emission results, it is determined that HC and CO emissions decreased by 10.42% and 4.41% respectively while CO2 and NOx emissions increased by 17.38% and 15.24% respectively
