In the current study,
biodiesel fuels produced from waste chicken fat and waste fleshing oil with
high free fatty acid were tested in a four stoke,
four-cylinder, water-cooled,
turbocharged-intercooled, common rail
direct injection (CRDI) diesel engine.
Their effects on the injection and exhaust emission characteristics of the test
engine were determined and compared with those of petroleum-based diesel fuel
(DF) as the reference fuel. Engine tests were performed at different engine
loads and constant engine speed of 2000 rpm. Injection characteristics showed
differences with respect to engine load and fuel type. However, the effects of
biodiesel fuels on the injection profiles were more dominant for main injection
characteristics such as the start of main
injection, end of the main injection,
injection amount and injection rate and these effects became more pronounced
with increasing engine load. Compared to DF, animal fat based biodiesels had
better total hydrocarbon (THC) and carbon monoxide (CO) emissions, but their
carbon dioxide (CO2) and especially nitrogen oxides (NOx)
emissions were higher. In addition, waste fleshing oil-based biodiesel fuel
emitted lower emissions than waste chicken fat-based biodiesel.
