Experimental investigation of performance, emissions and tribological characteristics of B20 blend from cottonseed and palm oil biodiesels

Reserves of fossil fuel are being depleted, and its use to generate energy also affects the environment. Sustainable clean sources, therefore, need be produced meet demands. In this research, combined blended fuels were from cottonseed palm oil methyl esters with petroleum diesel fuel. To achieve benefits biodiesel (high calorific value) (low kinematic viscosity acid value), blend (C05P15, C10P10, C15P05) has been tested assess their effect on engine performance, emissions, tribological properties. The physicochemical properties all measured following ASTM D6751 standard. A single-cylinder, 4-stroke, natural aspiration used for testing. experimental results showed that have low brake thermal efficiency emitted fewer hydrocarbons, carbon monoxide, smoke opacity apart nitrogen oxides compared Based results, can as a substitute in engines without any modifications. • Palm cotton seed together make B20 fuels. less HC, CO emissions than Combined (C10P10) more BP BSFC individual (COME20). All average coefficient friction (COF)
