Abstract

Present experimental work is carried out for the study of effect of biodiesel blends, fuel Injection timing (FIT), Fuel injection pressure (FIP) along with exhaust gas recirculation (EGR) ratio in CRDI diesel engine for performance (BTE) and NOx emissions. The parameters of the engine were measured and analyzed at JB10,JB20 biodiesel blends, 10°,14°,18° CA BTDC Injection timings with 400,500 and 600 bar FIP for EGR rates of 10% and 20% at constant speed. The results revealed about improvement of performance in terms of brake thermal efficiency for blends JB10, JB20 blends with advancement of injection timing, higher FIP also a slight increase NOx emissions were observed when working with biodiesel. Usage of EGR reduced the NOx emissions without affecting its efficiency, hence it can be optimized that engine operating with the combination of biodiesel blends and along with EGR rate culminates into NOx reductions without compromising its performance.
