Engines have been used in various fields and its field of application is still increasing with the passage of time. With the increased usage of the engines, fuel required is higher and so the demand of petroleum fuels is increased. Alternate fuels have been used to fulfill the demand of fuel. Moreover the very low emissions norms have led to the experimentation and analysis to attain preferred operating parameters of the engines run with these alternate fuels. Analysis of operating parameters to suit these alternate fuels have been in study to improve the performance and also emission reduction of engines. Ethanol, a renewable fuel which is widely available from the agricultural wastes has been in study to be used as a fuel in conventional engines in many countries. This experiment’s objective is to analyse the working of a single cylinder diesel engine using Ethanol blend with different injection pressure and compression ratio. The engine is run with both Diesel and also Ethanol blend at various selected parameters. The engine operation involves different percentage of Ethanol as 10%, 20%, 30%, 40% and also 50% ethanol and observations carried out for the same. The injection pressure used is 205, 230, 255 & 270bar with compression ratio as 17.5, 18.5 & 19.5 CR. Ethanol with low density & higher heat of vaporization needs low injection pressure & higher compression ratio for efficient working. Also the emissions using Ethanol fuel are much lower as the ethanol fuel has no aromatic chain that causes soot formation and reduced NOx emission. 10% Ethanol adaption at 230bar IP & 19.5CR provides the highest efficiency and also optimized emission like NOx, HC and CO.
