Performance, combustion and emissions characteristics of palm biodiesel blends in CI engines

Abstract

Biodiesel is an alternative fuel with the same properties compared with diesel. Biodiesel is one of the renewable resources. After using cooked oil is thrown away and it affects the environment. So, with the help of waste cooked oil is used to produce biodiesel the process is going to be done by the Trans-esterification process the Biodiesel were prepared as B60 and B100. The experiment was carried out in a single cylinder four stroke diesel engine at various crank angles of 19, 23 and 27 for both B60 and B100. Biodiesel has a higher peak cylinder pressure than diesel fuel during retardation of crank angle. It was found that B100 blends have lower net heat release, rate of pressure rise and lower mass fraction due to inferior volatility and higher viscosity. B60 IT23 blend has a higher mechanical efficiency than diesel. The CO2 emissions of biodiesel (B60 IT23) are slightly less than diesel. Hence the replacement of Palm biodiesel blends in the place of diesel gives promising results; which is nearer to diesel.
