Experimental investigation performance on a variable compression ratio engine using marotti biodiesel, comparing response surface techniques and computational fluid dynamics modeling

Abstract

We obtain fossil fuels from burning or decomposing dead organisms which are natural processes Crude oil coal and natural gas are a few of the more wellknown fossil fuels In order to obtain fossil fuel more dangerous gases are burned which causes social and environmental problems like global warming and air pollution In this case biodiesel is viewed as an alternative to clean environmentally friendly renewable energy sources This study focuses on Marotti oil a biodiesel fuel substitute for diesel engines with variable compression ratios VCRComputational fluid dynamics CFD software from ANSYSsoft is used to simulate a variable compression ratio engine while changing the relevant parameters When Marotti oil is applied to automobiles issues like a cooking injector lubrication a gumming filter etc are resolved Results are assessed based on emission and performance Response Surface Method RSM is used in the planning of the experiment to select the sequence factors The improved and increased nitrogen oxides enable important parameters like the combustion ratio fuel injection pressure and start of injection to perform as intendedBy reducing carbon dioxide and hydrochloride which increases thermal energy Marotti oil is used It is evident that biodieselbased fuel is environmentally friendly and improves engine performance
