Abstract

Most palm oil manufacturers, such as Indonesia and Malaysia (which contribute 80–85% of global capacity), have substantially invested in developing multiple techniques to convert palm oil, into biodiesel. Palm biodiesel output has also grown in comparison to petro-diesel. More appealing since, based on present practices in the Malaysian palm oil business, it has the potential to reduce GHG emissions by 50–70%. Differences of various biodiesel feedstock such as palm oil will generate differences in engine performance and exhaust emissions. The purpose of this study is to clarify the exhaust gas emission and engine performance produced from B20 and B30 palm oil biodiesel-diesel blends fuel in a fuel injection single-cylinder diesel engine by 3 different loads. The transesterificationprocess has been used to produce palm oil biodiesel-diesel blend fuel. The engine being coupled to an engine dynamometer to measure the engine performance parameters and a gas analyzer to measure the exhaust emissions from the engine. An engine run has been done by using D100, B20 and B30 to inspect the condition of the engine and to evaluate the data of engine performances and exhaust emissions. The result indicates that B20 and B30 biodiesel fuel was the optimum blend that had improved the engine performances and reduced the exhaust emissions without making any modifications to the direct-injection diesel engine. B20 biodiesel produced highest horsepower and torque even it consumed highest volume of fuel to travel. Other than that, B30 biodiesel emitted the lowest exhaust emissions except for Nitogen Oxide and Carbon Dioxide. Biodiesel fuel can be clarified as an effective solution to reduce greenhouse effect that produced from burning of fossil fuel.
