Abstract
The present work investigates the performance of a single cylinder, air cooled, direct injection (DI) compression ignition engine, using blends of biodiesel from non-edible feedstock-Citrullus colocynths L. methyl ester (CCME) and Diesel. The engine was tested with diesel (B0), 10% Biodiesel (B10), 15% biodiesel (B15) and 20% biodiesel (B20). The biodiesel is produced using transesterification process. The investigations have been studied for two compression ratio (CR) values of 14 and 16 with different blends of biodiesel at different load conditions. CO2 emissions were found to increase with increase in blending and CR, whereas increase in load showed a decrease in exhaust CO2 values. HC emissions decrease substantially with increasing blend ratio of biodiesel, compression ratio and load on engine. NOx emissions were increased with all blends of biodiesel, and increase in compression ratio and load also evidenced a subsequent increment in NOx emissions in exhaust.
