Abstract

Increasing demand for petroleum diesel, long to increase in harmful air pollution. Excessive use of diesel 
fuel, present an opportunity to develop environmentally friendly and renewable fuels for current diesel 
engines that have not been upgraded. The effects of using biodiesel, generated from palm olein oil and 
derived through transesterification, along with biodiesel and diesel fuels blends in varying percentages, as 
a fuel in a TD202, a small air-cooled single-cylinder diesel engine. According to the results of the 
experiments, as the biodiesel percentage in the blend increased, compared to fossil diesel, thermal 
efficiency declined by 2.84% and specific fuel consumption increased by 0.0438 kg/kW-h for B100. 
Moreover, the result obtained from the emissions analysis reflects that the average carbon monoxide 
(CO) value decreased by 0.03 % vol., hydrocarbon (HC) value decreased by 6ppm, carbon dioxide (CO2) 
emission increased by 1.4 % vol. for the given load, and nitrogen oxides (NOX) increased by 262 ppm, 
indicating that the mixture was stable in comparison with fossil diesel.
