Abstract

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 smoke or
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 the smoke and PM
emissions.
