Experimental investigation of optimizing hydroxy gas production and engine performance using orange peel oil diesel blend on a crdi engine

Abstract

The escalating usage of biofuels to replace hydrocarbon fuels and stricter emission standards for I.C engines make it extremely difficult for engine manufacturers to develop engines that can efficiently work with minimal levels of exhaust emission. The main goal of this research is to efficiently use hydroxy gas with biodiesel blends obtained from waste discarded material in a single-cylinder Common rail direct injection engine with modified combustion bowl geometry. The experimental study was carried out on a Kirloskar make single-cylinder four-stroke Common rail direct injection engine to determine the impact of dual-fuel operation on engine performance, combustion and emission characteristics. Dual fuel mode is a promising technique in diesel engine research concepts aimed at improving performance and reducing smoke emissions. newlineIn the first phase, the hydroxy gas was produced using a plate-type electrolyzer by the water electrolysis method. The Taguchi and grey relation analysis identified the most efficient operating parameters to produce hydroxy gas. Hydroxy gas was injected into the inlet manifold as a primary fuel at different flow rates such as 0.5, 1, 1.5, and 2 Litre per minute. In the second phase, the biodiesel obtained from the waste discarded orange peels was blended with diesel in different volumetric proportions such as 25, 50, 75, and 100 % after the transesterification process. These blends are tested in the Common rail direct injection engine at different load conditions newline
