摘要

High cost of edible feedstocks, food vs fuel debate, threat of deforestation, environmental pollution, damage to wildlife habitat, etc has shifted the attention of researchers to the generation of biodiesel from waste or used frying oil. This paper reviews recent researches on the performance and emission characteristics of waste cooking oil methyl ester in an unmodified conventional compression ignition engine. The general consensus among most authors is that the use of waste cooking oil methyl ester was found to result in increased brake specific fuel consumption, brake thermal efficiency and higher exhaust gas temperature when compared with petroleum-based diesel fuel. Most authors reported that diesel engines fuelled with pure biodiesel emitted less carbon monoxide, carbon dioxide, particulate matter and unburnt hydrocarbon but higher nitrogen oxide compared with diesel fuel. The oxygenated nature and other fingerprints of the biodiesel were responsible for the outcomes of the tests. However most of the research were not carried out in substantial compliance with established performance regulations and emission protocols.
