Abstract

Crude palm oil (CPO) was treated using different methods in order to use and test it as fuel in Compression Ignition (CI) engines. The treatments include CPO preheated and preparation of CPO/diesel oil blends, using mixtures of CPO with waste cooking oil (WCO), which are converted into esters by a transesterification process. The purpose of this study is to evaluate the potential of the palm oil-based biofuels to replace diesel oil in CI engines. Tests were conducted in a single cylinder, four-stroke, air-cooled, direct injection diesel engine (no engine modifications were required). Experiments were initially carried out with diesel oil for providing baseline data. All the tested fuels have a low heating value compared to diesel fuel. A high fraction of CPO in diesel fuel decreases the heating value of the blend. The brake thermal efficiency increases for the PO/Diesel blends. HC emissions for all those fuels except for the CPO/Diesel blends are found lower, while CO emissions rise for all types of fuels.
