Performance study on the C.I engine using LHR and LTC in combination with biodiesel blends

Abstract

In the occurring period of now, the study of a single-cylinder 4-stroke direct injection diesel engine was used, which was naturally aspired, and two modification methods were used. One is the low-heat rejection method (LHR) and the other is the low - temperature combustion method (LTC). LHR was implemented to the engine by ceramic coating with alumina is coated to an engine components like piston, cylinder liner and valves which is having thickness of 300 microns without effecting the dimensions of engine parts. In the next method, low - temperature combustion (LTC) method is done with EGR technique. And the exhaust gas recirculation setting (EGR) is included in the same setup as that of first method. Since, 15% of an exhaust gas is used in the EGR process. The diesel is blended with 20% of mahua biodiesel and 5% of ethanol as a fuel. After that, the engine performance is tested with conventional fuel when compared with biodiesel as a combined LHR and LTC methods. Finally, the engine performance is achieved up to 3.48% as a result of change made by the combined use of LHR and LTC. Thus, the emission levels could be significantly reduced and other results obtained can be include a reduction in infrared radiation, therefore a reduction in specific fuel consumption (SFC), and a significantly increased in performance characteristics of an engine.
