| Abstract | ||
| This study examines the characteristics of combustion, performance and emission of constant speed compression ignition engine fed with different percentages of diesel fuel and rapeseed methyl ester (RME) on a volume basis by using the well-known software simulation Diesel-RK. As the percentage of RME increased, the maximal pressure is noticed to be closer to top dead center (TDC). It was found that 47.27 %, 81.06 %, 82.56 % and 93.36 % reduction in the Bosch smoke number is obtainable with 10% RME, 20% RME, 50% RME and 100% RME respectively, compared with ordinary diesel. The blends of RME are noticed to emit higher NOx emissions. The result signals that 10% RME is the promising ratio of blending which reports less performance variations and reduced carbon emissions as well. The effect of variable injection timings is studied to moderate biodiesel NOx effects on the 10% RME and 18 degree crank angle before top dead center (BTDC) was recorded as the advisable injection timing which gives a promising reduction in NOx emissions. | ||
