Effect of Safflower Methyl Ester in a Four Stroke Natural Aspirated Direct injection Diesel Engine

V. Balaji, S. Mohanamurugan and P. K. Nagarajan

The performance of biodiesel obtained from safflower oil and its blend were measured and evaluated in four stroke, single cylinder, direct injection diesel engine. Properties were found to be comparable to diesel and confirming to both the American and European standards. Engine performance (brake thermal efficiency) and emissions (CO, smoke density and NOx) were measured to evaluate and to compute the behaviour of the diesel engine running on biodiesel. The reduction in exhaust emissions and brake thermal. which makes the blend of biodiesel (B40) a suitable alternative fuel for diesel and it could help in controlling air pollution
