Abstract

Energy is a fundamental necessity for man›s life in the digital world today. The rapid depletion of fossil fuel resources forces rigorous alternative fuel analysis. Petroleum diesel can better replace vegetable oils, edible or motored today. The rapid depletion of fossil fuel resources forces rigorous alternative fuel analysis. Petroleum diesel can better replace vegetable oils, edible or not. Karanja may be a possible supplier of diesel fuel for non-edible oil substitution. Current combustion surfaces for pistons, valves, and cylinders have been filled with ceramic materials, which make the engine totally adiabatic (LHR). The performance of a biodiesel-powered compressing ignition (CI) engine may be further boosted by utilising the engine›s heat effectively and increasing thermal efficiency. Exhaust Gas Recirculation (EGR) is actually one of the most important methods of limiting NOx emissions in internal combustion engines. Explore the output with and without exhaust gas recirculation on a retarded timing engine with diesel and karanja oil methyl ester (KOME). The LHR with a retarded timing engine yielded improved thermal brake efficiency (TBE), decreased HC, smoke, and CO emissions, while increasing KOME›s NOx in comparison with an uncoated engine. As the EGR rate grew, NOx and BTE were reduced marginally with increased HC, CO, and smoke. 24.1 g/kw-hour CO, 10.1 g/kw-hour NOx, and 0.55 g/kW-hour HC were registered at 20 percent of EGR.
