Biodiesel is an alternate fuel for Diesel engine due to its properties is close to diesel fuel. Also it is biodegradable, non-toxic, and renewable in nature. In the present work, the performance, emission, and combustion characteristics of a Diesel engine using diesel and 25% rubber seed oil methyl ester diesel blend have been investigated with the effect of different injection pressures like 200 bar, 225 bar, and 250 bar with different load conditions. The biodiesel was prepared from raw rubber seed oil using transesterification process. The performance and emissions parameters were measured and compared with diesel and B25 blend with standard injection pressure of 200 bar. The results showed that the brake thermal efficiency for 25% rubber seed oil methyl ester is increased with 250 bar injection pressure compared to other injection pressures. It is closer to diesel fuel operation with standard injection pressure of 200 bar injection pressure at full load. The carbon monoxide, hydrocarbon, and smoke were decreased for the injection pressure 250 bar, whereas the NO emission is increased at full load compared to other injection pressures. The cylinder peak pressure, heat release rate are increased for 25% rubber seed oil methyl ester and the ignition delay is decreases with increase in injection pressures.
