Abstract:- Current energy regulations address environmental concerns, climate change, and the promotion of greener energy. Because of the use of fossil fuels, air pollution has become a severe hazard to human survival. In terms of fossil fuel usage, India ranks third in the world, posing challenges to social and economic growth. The simplest way is to use vegetable oil in a CI engine, but due to their high viscosity and low volatility, direct injection of vegetable oils into a CI engine causes several operating and durability issues. This issue is solved by preheating the oil using exhaust gas in a shell and tube heat exchanger, which reduces chemical processing costs. Present experimental research on the performance, emission, and combustion characteristics of diesel and hone oil blends (D100, B20, and B40) with preheating at various loads. The above blends are compared unheated and preheated by analysing various parameters such as break thermal fuel consumption BSFC,ISFC, thermal efficacies, powers, mass emission of various gaseous pollutants species such as CO,HC,CO2 and NOx, combustion parameters such as indicated mean effective pressure IMEP,BIMEP and FMEP, and so on. A thorough investigation found that all performance criteria are greatly improved, and in the event of blending, preheating delivers comparable results to diesel injection while producing lower emissions. Preheating reduces CO, CO2, and HC emissions by 20-25 percent due to enhanced combustion, while NOx emissions increase as combustion temperature rises.
