Experimental and CFD Analysis of Combustion in Diesel Engine for Various Ethanol-Diesel Blends

Diesel engines are used widely around the globe as power plants for various purposes due to their excellent drivability and economy. But they are also the major contributors of air pollutants such as CO, NOx, PM and other harmful compounds. At the same time the global fuel crises and increase in fuel prices have led us to the need of developing an alternate fuel that would give a solution to these problems. For about a decade researches and investigations were conducted on the use of ethanol-diesel blend as a fuel in diesel engines. Many proposals were made and few are commercially implemented. Many of the results comes to a conclusion that ethanol-diesel blend could solve the problems mentioned above. The aim of this project is to find the optimum ethanol-diesel blend that suits the diesel engines presently available in the market and could be used without much modification in the engine. With the help of various methods to find fuel properties, performance test on diesel engine for various fuel blends and software analysis the optimum blend is found out. The blend of fuel found out as the result of this project could be the fuel that drives the future
