Abstract: Abstract This study investigates the possible impact of rapeseed methyl ester (RME) biofuel, caster methyl ester biofuel (CME), and engine speed on the performance, combustion, and emission of a multi-cylinder turbocharged direct injection diesel engine with high compression ratio numerically. According to the numerical simulation results, biofuel reduces the peak cylinder pressure closer to the top dead centre than that of diesel fuel. Because they used more brake-specific fuel (BSFC), both of the biofuels used had less stopping power than diesel fuel. The amount of NOx dropped by 50% when RME was used instead of DF. In the case of CME, 19% less smoke was made, but in the case of RME, only 15% less smoke was made. When RME and CME are used instead of DF, the Sauter mean diameter (SMD) goes up. The ID is shorter when biofuel is used because of the change in the cetane number. Because of the drop, biofuel starts to burn (SOC) faster than DF. As the engine speed goes from 1000 to 4000 rpm, the peak pressure goes up while the SMD goes down. There is a small difference between the findings and what other experts have found.
