In this study were investigated that the effect onperformance and emissions of spark ignition engine by used n-propanol andiso-propanol alcohol. In experiments were used B100(100% gasoline), 20 n-pro(80% gasoline+20% n-propanol) and 20 iso-pro (80% gasoline+20% iso-propanol)fuel blends. Experiments was performed that engine full throttle in theposition and six different engine speed (1500-4000 d/min). According toperformance results, was not observed that significant a change on enginemoment and engine power with add iso-propanol alcohol. But specific fuelconsumption was increase that 2.23% rate with using iso propanol alcohol.According to the emissions results, HC and CO emissions were reduced with addalcohol about %10.52 and % 4.41 respectively. On the other hand, NOXand CO2 emission increased about %17.38 and %15.24 respectively.

Bu çalışmada buji ateşlemeli bir motorda n-propanolve izo-propanol alkolleri kullanımının motor performans ve emisyonlarına etkisiincelenmiştir. Deneyler de B100 (%100 benzin) 20 n-pro (%80 benzin+%20n-propanol) ve 20 izo-pro (%80 benzin+%20 izo-propanol) yakıt karışımlarıkullanılmıştır. Deneyler motor tam gaz konumunda, altı farklı motor devrinde(yükünde) (1500-4000d/dk) yapılmıştır. Performans sonuçlarına göre,izo-propanol alkolü ilavesi ile motor momentinde ve motor gücünde önemli birdeğişiklik görülmemiştir. Fakat özgül yakıt tüketimi izo-propanol alkolkullanılmasıyla %2,23 oranında artmıştır. Emisyon sonuçlarına göre, HC ve COemisyonları alkol ilavesi ile birlikte sırası ile yaklaşık %10,52 ve % 4,41azalmıştır. Öte yandan CO2 ve NOX emisyonları sırası ileyaklaşık %17,38 ve %15,24 oranındaartmıştır.
