Abstract

In this experimental study, different octane number fuels, which are selling nowadays, are tested in a spark ignition engine. In the tests, 95, 97 and 100 octane gasoline fuels were used. The experiments were performed at full load and different engine speeds between 1500-4500 1/min with 500 1/min intervals. A four cylinder, four stroke spark ignition engine having 8,8 compression ratio was used in the tests. Engine performance and exhaust emission variations were obtained using higher octane number fuels and different throttle positions without modification of the engine. The results were showed that maximum performance characteristics were obtained with 95 octane number standard fuels. In addition to this, CO and HC emissions were increased and $NO _x$ emissions were decreased when higher octane number fuels are used

Özet

Yapılan bu deneysel çalışmada piyasada satılan değişik oktan sayılı benzinler buji ile ateşlemeli bir motorda test edildi. Testlerde 95-97-100 oktanlı benzinler kullanıldı. Deneyler tam yükte ve 1500-4500 1/min arasında 500’er devir aralıklarla 4 silindirli, 4 stroklu ve 8,8 sıkıştırma oranlı buji ateşlemeli bir motor üzerinde gerçekleştirildi. Motorun teknik özelliklerinde değiştirme yapılmadan, günümüz taşıtlarda kullanıldığı gibi, motorun ihtiyaç duyduğundan daha yüksek oktanlı benzinler kullanılarak ve farklı gaz kelebeği açıklıklarındaki motor performans ve emisyon değişimleri bulundu. Deneyler sonunda motorun standart yakıtı olan 95 oktanlı benzinin en iyi performans değerlerine sahip olduðu tespit edildi. Ayrıca aynı motorda yüksek oktanlı benzinlerin kullanılması durumunda, CO ve HC emisyonları artar iken, $NO _x$ emisyonlarının da azaldığı belirlendi.
