OPTIMIZATION OF A SINGLE CYLINDER, 4-STROKE DIESEL ENGINE PERFORMANCE PARAMETERS USING DIESEL/COTTON SEED OIL BLEND WITH HYDROGEN INDUCTION BY TAGUCHI METHOD

The performance of a diesel engine by blending cottonseed oil with the diesel and suction is enriched with hydrogen inducting through port in the suction stroke. The process parameters identified are injection operating pressure (IOP), compression ratio (CR) and amount of hydrogen each at three levels. Taguchi L9 OA is chosen for the experimentation and two responses have been recorded namely brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC). The contribution of these parameters on these parameters on those responses has computed by signal to noise (S/N) analysis.
