OPTIMIZATION OF COMPRESSION IGNITION ENGINE FUELLED WITH COTTON SEED BIODIESEL USING DIGLYME AND INJECTION PRESSURE

Tóm tắt

The main research problem from the usage of diesel engine arises from increased fuel prices and emissions releasing from combustion. The objective of the current work relies on finding out a suitable biodiesel blend and improving the diesel engine characteristics by means of additives. The current study discusses about the optimization of the diesel engine characteristics employing cotton seed biodiesel (CSOME) blends. CSOME 20 was found to give the better engine characteristics. Also the engine characteristics were optimized with the addition of diglyme at proportions of 10 and 15% to CSOME20. Along with further optimization was done with varying injection pressure values. It was observed that CSOME DGM 15 reduced the smoke and carbon
monoxide emissions with rise in Nitrogen Oxides. BTE was recorded to be highest at 220 bar. Smoke and hydrocarbon were found to be minimum at 220 bar with maximum NOx emissions.
