The emission norms becoming very stringent and the price of the fuel shooting its height, there is a need for reducing the emissions and to improve the performance of the engine. In CI engine, the combustion is heterogeneous and the time allowed for mixing of fuel with air in particular oxygen is very less so there is partial mixing of the fuel which makes the mixture rich at certain places leading to the formation of particulate matter and very leaner at some places leading to formation of NOx. Some research outcomes shows that oxygenate when mixed in the fuel prior to combustion can improve the performance and also reduces the emissions. In this research the DEE is mixed with Diesel for 5% and 10%, and the combustion and emission characteristics are analysed. The result shows promising characteristics in performance improvement and Emission reduction.
