EFFECT OF L-ASCORBIC ACID AS ADDITIVE FOR EXHAUST EMISSION REDUCTION IN A DIRECT INJECTION DIESEL ENGINE USING MANGO SEED METHYL ESTER
ABSTRACT
In this present study the effect of L-ascorbic acid antioxidants additive for oxides of nitrogen emission reduction in a neat mango seed biodiesel fueled direct injection Diesel engine. The antioxidant additive L-ascorbic acid is tested on a Kirloskar-make four stroke water cooled single cylinder Diesel engine of 5.2 kW. There are four proportions of additive are used:1 ml, 2 ml, 3 ml, and 4 ml. Among the different additive proportion,4 ml concentration of L-ascorbic acid additive is optimal as oxides of nitrogen levels are substantially reduced up to 9% in the whole load range in comparison with neat biodiesel. However, hydrocarbon and carbonmonoxide emissions are found to have slightly increased by the addition of additive with biodiesel.
