Abstract

In this study, the emissions of Kirloskar Direct Injection 4-stroke Diesel engine, single cylinder air cooled, 4.4 kW, constant speed at 1500 rpm, compression ratio 17.5:1 with different blends of diesel refined sunflower oil is analysed. Methyl Esters of refined sunflower was trans-esterified before blending with diesel. The main objective of this experiment is to study the NOx, CO, HC and smoke emissions by varying the injection timing and load. The experiments were conducted with various blends - BRSF10, BRSF30, BRSF40, at different pressures (180 bar, 210 bar, and 240 bar) and different level of loads (0%, 25%, 50%, 75%, 100%). A 3-hole nozzle was used to inject the fuel. The combustion results were studied using AVL gas analyser. The results show that engine temperature decreases at higher loads by 2°, NOx and CO decreases and there was a marginal increase in HC and the exhaust temperature.
