Performance, combustion, and emission characteristics of direct injection diesel engine fueled with ZnO dispersed canola oil biodiesel

Diesel engines are critical to economic mobility. Because of the increasing scarcity of petroleum resources and the strict administrative rules, engine manufacturers and users must follow environmental regulations to avoid undesirable emissions. Vegetable oil could be used in diesel engines due to its high fluidity, poor stratification, ineffective ignition, and carbon buildup in the fuel system. The transesterification method reduces the viscosity of vegetable oil by converting it into methyl ester or ethyl ester, which is also known as biodiesel. This research examined the productivity, combustion, and output of zinc oxide nanoparticle disseminated canola oil biodiesel. The canola oil biodiesel was produced using the traditional transesterification process. The experimental hydrocarbons were produced using a magnetic agitator and ultrasonication, with a scattering of zinc oxide nanoparticles at a dosage of 50mg/l. The experiments were conducted at 1500 rpm. The use of zinc oxide nanoparticle dispersed canola oil biodiesel improved the specific fuel consumption, heat release rate, and other parameters. When compared to diesel, the brake thermal efficiency, nitrogen oxide, and hydrocarbon emissions were all lower. This study provides critical guidance on the use of sustainable energy, resulting in lower conventional oil consumption.
