Abstract

The search for permanent fossil fuel substitutes has become critical due to the declining supply of fossil fuels and the toxic pollution emitted by diesel engines. In this study, diesel engine characteristics have been investigated numerically and experimentally using diesel, biodiesel mixture from waste vegetable oil and soybean oil (BM100) and butanol blends (5%, 10%, and 15%). The experimental work was conducted on the single-cylinder diesel engine generator at different speeds (1000, 1500, 2000, and 2500 rpm) and full load conditions. A commercial Diesel-RK software was used to perform the numerical aspects of the diesel engine. The different percentages of butanol blends were added to biodiesel mixture to form biodiesel mixture-butanol blends. It was discovered that there was good agreement between the experimental and numerical results. The cylinder pressure, heat release rate, brake power, brake-specific fuel consumption, brake thermal efficiency, nitrogen oxide, carbon dioxide, and particulate matter (PM) emissions were all predicted using the numerical technique. Results showed a decrease in carbon dioxide, particulate matter, and brake power. When compared to regular diesel fuel, at maximum speed, there was a decrease in brake-specific fuel consumption and an increase in nitrogen oxide emissions.
