OPTIMIZATION OF FUEL INJECTION PARAMETERS FOR ENHANCED COMBUSTION AND PERFORMANCE ANALYSIS OF VCR ENGINE USING DUAL BIOFUEL BLENDS AND ADDITIVES

Abstract

The increasing use of Automobiles has led to a rise in fuel consumption and emissions, particularly in developing countries. To mitigate emissions from diesel engines and enhance performance, biofuel blends with advanced biofuels offer a promising solution. This research examines the functionality and emissions of a diesel engine using Biobutanol (Advanced Bio-alcohol) blended with Dimethyl Carbonate (DMC) and Diethyl Ether (DEE) as oxygenated additives. The research focuses on comparing biodiesel Characteristics of biofuel blends with conventional diesel fuel while varying the compression ratio in a Variable Compression ratio Engine (VCR). The aim to optimize fuel pressure strategies for increased Engine performance, lower emissions, and better combustion efficiency. The fuel blends were prepared by combining Diesel with biobutanol and dimethyl carbonate with varying amounts like B10D90 which indicates Biobutanol with Dimethyl Carbonate 10% Biodiesel and 90% diesel were created, as were B20,D80, additionally, these mixtures are dosed with and B30D70 and B30D80 diethyl ether in percentages (5%, 7.5% and 10%) additive is to be used to improve the Cetane number of the fuel to lower the oxides of nitrogen emission. The Performance metrics such Brake power, Specific fuel Consumption and Brake thermal Efficiency were Calculated. Emissions from Smoke CO2 , CO and NOx have been Assessed.
