Experimental Investigation on Performance and Emission Characteristics of A Diesel Engine Fueled With Nerium Oil As Biodiesel

Homogeneous Charge Compression Ignition engines have potential to provide like efficiencies and very low NOx and particulate matter emissions. There is growing global interest in using alternative biofuels in order to reduce the reliance on conventional fossil fuels. Therefore this experimental study was carried out to investigate performance and emission characteristics of HCCI engine fuelled with Nerium oil and compare it with baseline diesel fuel. The experiments were conducted on a modified single cylinder four-stroke engine at different engine speeds using port fuel injection technique for preparing homogeneous charge. To achieve auto-ignition of air–fuel mixture in the combustion chamber, intake air pre-heater was used. The results show that nerium oil has good replacements to diesel in HCCI combustion mode.
