Compression ignition (CI) engine is the un-debated choice for power applications, stationary or mobile. There is an urgent need of alternative high potential fuel for CI engines in order to fulfill energy needs without hampering the thermal performance and stringent emission standards. Here waste cooking oil is chosen as an alternative fuel, which is upgraded into biodiesel in the laboratory using mechanical stirring and ultrasonic cavitation technique of biodiesel production. Four blends of cooking oil are made by increasing 20% its amount in conventional diesel fuel. Performance is analyzed for two compression ratios, 15 and 17.5, on the existing VCR diesel engine set up interfaced with “Engine Soft” software. The results show that as bio-diesel concentration in a blend increases, the thermal performance (i.e., brake thermal efficiency) and emissions (i.e., CO, HC and NOx, and smoke intensity) are observed to be marginally higher; on the other hand, as compression ratio increases, the thermal performance improves; CO and smoke opacity decreases.
