The effects of using ethanol as additive to biodiesel-diesel blends on engine performance, emissions and combustion characteristics was investigated on a four-cylinder, turbocharged and high-pressure common-rail direct injection diesel engine. Three test fuels have been compared: baseline diesel, coconut oil methyl ester (CME) with 20% of biodiesel by volume (B20) and 5% of ethanol and 20% of CME by volume (B20E5). The tests were performed in steady state conditions at 2000 rpm with 25%, 50% and 75% load setting conditions. The results indicate that higher brake specific fuel consumption and brake thermal efficiency is observed when operating with B20 and B20E5 blend. B20E5 blend shows reduction in smoke opacity, CO and NOx emissions compared to baseline diesel fuel. In terms of combustion characteristics, B20E5 shows slightly higher in both of the peak pressure and peak of HRR at low engine load.

High Pressure Common Rail

To study the effect of the biodiesel on the performance of the high pressure common rail diesel engine performance, a experiment is conducted about the high pressure common rail diesel engine uses diesel fuel and different blending ratio of biodiesels. The results show that with the rising of the altitude, the engine power and the brake specific fuel consumption reduce, exhaust gas temperature increases; At the same altitude, the engine fueled with different blending ratio of bio-diesel has higher brake specific fuel consumption in comparison with fueled engine, but it has lower power, with the increase in bio-diesel blending ratio, engine power, fuel consumption increase.
