Abstract

Waste cooking oil (WCO) is a potential solution to the problems of environmental contamination and fossil fuel depletion as an alternative fuel for compression ignition (CI) engines. Nevertheless, CI engines poor combustion due to WCO low fuel qualities has resulted in subpar engine performance and increased exhaust pollutants. In order to solve these problems, various methods were used in the current experimental effort to enhance a CI engine performance and combustion properties when WCO was used as the base fuel. Diesel and WCO were used as fuels in the experiments carried out in the first part of the project and the outcomes were recorded as baseline data. In the second stage, a transesterification process transformed WCO into waste cooking oil biodiesel (WCOB), which was then used in studies. The findings demonstrated that in comparison to WCO, Brake Thermal Efficiency (BTE) increased when WCOB was used. Better performance and combustion characteristics were demonstrated by WCOB. In the projects last stage, experiments were carried out using zinc oxide nano fluids that had been prepared in four different quantities and mixed with WCOB. When compared to WCO and WCOB, the BTE was better. Compared to WCO and WCOB, it demonstrated superior performance and overall combustion characteristics.
