Abstract

Diesel engines play a primary role in energy and transport sector. This engine typically transforms relatively less heat energy into mechanical work and furthermore emissions exhausted by these engines results in environmental degradations. To address these challenges, the present study involves the use of blend B25 of jatropha biodiesel as secondary fuel on a constant running single cylinder CI DI engine with standard and modified piston. The feedstock seed employed is cost found cost effective and contains significant oil content of 31%. The chemical approach employed resulted in 80% of biodiesel yield. The B25 blend resulted in better BSFC and BTHE with declined emission except the emission of NOX. At a maximum load, when compared with conventional fuel, the BSFC of B25 (0.263 kg/kWh) increased by 4.37%, while the BTHE is declined by1.06%. Coating on piston accomplished by plasma spray technique improved BSFC by 2.28% and BTHE by 3.28% over the standard piston configuration. Emissions analysis revealed that the standard piston reduced CO, HC, and Smoke density by 14%, 7.27%, and 8.16%, when compared with the conventional fuel. The coated piston further enhanced these reductions by 6.98% (CO), 9.80% (HC), and 4.44% (Smoke) than the standard configuration. The primary drawback was a 3.58% increase in NOx emissions.
