Abstract
The diesel engines are emitting toxic gases which affect the greenhouse gases. In this research, the methyl esters were extracted from waste papaya seed oil using transesterification process. The Direct Injection Kirloskar diesel engine at constant speed of 1500 rpm and compression ratio of 17.5:1 was used to test the fuel. The injection nozzle holes were varied from 3 to 4 holes. The emissions were recorded using AVL gas analyser. The 20% blend with 4-hole nozzle shows reduction in NOx, CO and CO2 emissions at full load. The performance is increased for 30% blend at full load.
