Abstract

Diesel engine emissions can be improved by adding organic oxygenated compounds to the No. 2 diesel fuel. In this study, effects of 10 % and 15 % (in volume) ethanol addition to Diesel No. 2 on exhaust emissions from an indirect injection turbocharged diesel engine running at different engine speeds and loads were investigated. Experimental results showed that the ethanol addition reduced CO, soot and $SO_2$ emissions, although it caused some increase in $NO_x$ emission and some power, reductions due to lower heating value of ethanol. Improvements on emissions were more significant at full load rather than at partial loads.

Özet

Organik oksijenli bileşiklerin Dizel No.2 yakıtı ile karıştırılarak kullanılması ile dizel motor emisyonlarında olumlu iyileşmeler olmaktadır. Bu çalışmada Dizel No.2 yakıtına %10 ve %15 hacimsel oranlarında etanol karıştırılarak farklı motor dönme sayılarında ve yüklerinde çalışan bir ön yanma odalı turbo dizel motorun egzoz emisyonları incelenmistir. Deney sonuçları etanol ilavesinin, $NO_x$ emisyonunda artma ve ısıl değerinin düşük olmasından dolayı da bir miktar motor gücünde düşmeye sebep olduğunu göstermesine rağmen, CO, is ve $SO_2$ emisyonlarında azalma sağladığını-göstermektedir. Emisyonlardaki iyileşme tam yükte, kısmi yüklere nisbeten daha çok dikkate değer bir seviyededir.
