- An experimental investigation is carried out in a single-cylinder, constant speed diesel engine to study the effects of adding four different concentrations of N-Isopropyl-N'-phenyl-1, 4-phenylenediamine (IPPD) as an oxidant to a Jatropha Methyl Ester (JME) diesel blend comprising 20% JME and 80% diesel (JME20) on the performance and emission parameters of the test engine. The whole investigation is carried out in the diesel engine using the following fuels: diesel, neat JME20, and IPPD blended JME20 fuels in a low heat rejection (LHR) mode. The four different concentrations of IPPD used in the investigation are 500 ppm, 1000 ppm, 1500 ppm, and 2000 ppm. The experimental results revealed an appreciable reduction in the brake specific fuel consumption (BSFC) is noticed with the IPPD blended JME20 fuels compared to that of neat JME20 and diesel at full load. The value of BSFC for the JME20 fuel observed at full load is 0.69 kg/kWh, and it is 0.67 and 0.62 kg/kWh for the JME20A2 and JME20A3 fuels respectively. Further, due to the combined effects of micro-explosion and secondary atomization phenomena associated with the IPPD blended JME20 fuels the unburnt hydrocarbon (HC) and carbon monoxide (CO) emissions are lesser compared to those of normal diesel fuel operation.
