Palm oil is a vegetable oil which can be used as alternative fuel for diesel engine. The disadvantages are the high viscosity and palm oil is edible oil. The <br /> <br /> <br /> viscosity can be reduced by doing preheating or blend it with other fuel. This test is conducted to determine the effects of using preheated and blended 50% pure palm oil-diesel fuel as diesel engine fuel. <br /> <br /> <br /> This test is performed within 17 hours for each fuel and refered to SAE Paper 942010. The fuels are preheated and blended 50% pure palm oil-diesel fuel and unheated diesel fuel as benchmark. <br /> <br /> <br /> Result of the test, 50% pure palm oil-diesel fuel has worse performance (BSFC are higher 8,16%) and exhaust gas emissions. 50% pure palm oil-diesel fuel has higher deposit formation than diesel fuel, however it does not clogue the <br /> <br /> <br /> nosel. 50% Pure Palm Oil has spray visual characteristic similar as diesel fuel. However, 50% Pure Palm Oil lubricates the components better than diesel fuel.
