Summary: | Reserves of fossil fuel are being depleted, and its use to generate energy also affects the environment.
Sustainable and clean energy sources, therefore, need to be produced to meet the demands. In this
research, combined blended fuels were produced from cottonseed and palm oil methyl esters with
petroleum diesel fuel. To achieve the benefits of palm oil biodiesel (high calorific value) and cottonseed
oil biodiesel (low kinematic viscosity and acid value), the combined biodiesel blend (C05P15, C10P10, and
C15P05) has been tested to assess their effect on engine performance, emissions, and tribological
properties. The physicochemical properties of all fuels were measured following ASTM D6751 standard. A
single-cylinder, 4-stroke, and the natural aspiration diesel engine were used for engine testing. The
experimental results showed that all combined blended fuels have low brake thermal efficiency and
emitted fewer hydrocarbons, carbon monoxide, and smoke opacity apart from nitrogen oxides compared
with petroleum diesel fuel. Based on results, the combined blended fuel can be used as a substitute fuel
in diesel engines without any engine modifications. |
