This study was compiled from the results of various researches performed on using diethyl ether as a fuel or fuel additive in diesel engines. Three different techniques are used the reduction of the harmful exhaust emissions of diesel engines. The first technique for the reduction of harmful emissions is improved the combustion by modification of engine design and fuel injection system, but this process is expensive and time consuming. The second technique is the using various exhaust gas devices like catalytic converter and diesel particulate filter. However, the use of these devices affects negatively diesel engine performance. The final technique to reduce emissions and also improve diesel engine performance is the use of various alternative fuels or fuel additives. The major pollutants of diesel engines are oxide of nitrogen (NOx) and particulate matter (PM). It is very difficult to reduce NOx and PM simultaneously in practice. The most researches declare that the best way to reduce is the use of various alternative fuels i.e. natural gas, biogas, biodiesel or using the additives with alternative fuels or conventional diesel fuel. Therefore, it is very important that the results of various studies on alternative fuels or fuel additives are evaluated together to practice applications. Especially, this study focus on the use diethyl ether in diesel engines as fuel or fuel additive in various diesel engine fuels. This review study investigates the effects of diethyl ether addition on injection and combustion characteristics.

Abstract: In this study, the effects of compression ratio on performance, fuel consumption and exhaust emissions of a diesel engine have been investigated experimentally. Experimental study was performed by a four strokes, single cylinder, variable compression ratio and direct injection diesel engine. In the experiments, Euro-diesel fuel was used and measurement was completed for three different compression ratios (r =15, 16, 17) and under five different load conditions with 25% increment between 0–100% by operating the experimental engine at 1500 rpm stable speed. Performance parameters such as power, torque, brake thermal efficiency and specific fuel consumption were determined by using measured values. Additionally, carbon monoxide (CO), hydrocarbons (HC), nitric oxides (NOx) and carbon dioxide (CO2) emissions were measured by using the exhaust gas analyzer. The results of the study show that increments in compression ratio affect positively the engine performance and fuel consumption. Additionally, the emissions except for nitric oxides decrease when the compression ratio is increased.
Özet: Bu çalışmada sıkıştırma oranının bir dizel motorun performansına, yakıt tüketimine ve egzoz emisyonlarına etkileri deneysel olarak incelenmiştir. Deneysel çalışma dört zamanlı, tek silindirli, değişken sıkıştırma oranlı ve direkt püskürtmeli bir dizel motoru kullanılarak yapılmıştır. Deneylerde Euro-dizel yakıtı kullanılmış ve deney motoru 1500 d/dk sabit devir sayısında çalıştırılarak üç farklı sıkıştırma oranında (r =15, 16, 17) ve %0–100 arasında %25 artırımla beş farklı yükleme durumunda ölçümler yapılmıştır. Ölçülen değerlerden yararlanılarak efektif güç, döndürme momenti, efektif verim ve özgül yakıt tüketimi gibi performans parametreleri hesaplanmıştır. Ayrıca, deneylerde egzoz gazı analiz cihazı kullanılarak karbon monoksit (CO), hidrokarbonlar (HC), azot oksitler (NOx) ve karbondioksit (CO2) emisyonları ölçülmüştür. Çalışma sonuçları sıkıştırma oranının artırılmasının motor performansını ve yakıt tüketimini olumlu yönde etkilediğini göstermiştir. Ayrıca, sıkıştırma oranı artırıldığında azot oksitler dışındaki egzoz emisyonları da azalma meydana gelmiştir.
