Abstract: Faster exhaustion of fossil fuels and escalation of pollution levels have increased the requirement for alternate fuels to fulfil the energy demand of the fast growing world. The present work attempts to use waste plastic oil added with 1-Pentanol in a CRDI engine to achieve comparable performances of pure diesel with significantly reduced hazardous emissions. The experiments were carried out with 10, 20 and 30% of 1-pentanol blended with waste plastic oil on volume basis. The experiments were conducted at constant speed of 2000 rpm with load varying from 20 to 80% and exhaust gas recirculation by 10 and 20%. The fuel blend with 30% 1-pentanol exhibited 3.3% lower efficiency, 0.02 kg/kWh higher brake specific fuel consumption, 74 ppm of lower nitrogen oxide and 2.3 ppm of higher hydrocarbon emissions correlated to pure diesel. The use of exhaust gas recirculation reduced nitrogen oxides in the exhaust gas with slightly aggravated emissions of carbon monoxide. Considering the different combustion, performance and emission parameters, the fuel blend containing 30% of 1-pentanol and 70% waste plastic oil can be a potential alternate to pure diesel.
