Abstract	The research article presented here mainly focuses on the influence of pre and post-injection (split in to three injections) technique that was used to improve the ethanol fuel combustion in compression ignition mode (CI), with and without zirconia surface coating. Combustion simulation results and experimental results were investigated and compared with different experimental conditions. This research was used (95% Ethanol +5% water) as a fuel in a four stroke single cylinder variable compression ratio (VCR) engine. The VCR engine was used to optimize compression ratio (28.8:1) and conducted various experiments. Performance and exhaust emissions of NOx, CO and HC were compared with ethanol fuel split injection mode, single injection mode and diesel fuel mode. Brake thermal efficiency of pre and post injection mode was better than direct injection (DI) ethanol mode. The VCR engine operating with ethanol fuel split injection mode showed peak brake thermal efficiency (BTE) of 29%, which is nearly operating range in the baseline diesel engine. Ethanol fuel was mixed with 3% castorene R40 (lubrication oil) oil by volume due to fully soluble in alcohol fuels. It was used both air and liquid cooled engines running on methanol and ethanol fuel. Pre and post ethanol injection mode was 54.4 % reduction of Oxides of nitrogen (NOx) compared with single injection mode of operation. In comparison of diesel mode operation with zirconia coating was 3.8% increased than without coating.
