THE PERFORMANCE AND EXHAUST EMISSION OF A DIESELENGINE USING BIODIESEL FUEL FROM CRUDE PALM OIL (CPO)AND REFINED BLEACHED DEODORIZED OIL FROM PALM OIL(RBDPO)

摘要

Methyl ester from fatty acid of plant oils is called “Biodiesel” and has severaladvantages as follows; Carbon neutral and renewable energy due to biomass preventing anincrease green house effect gas emission; CO2, Safety fuel due to higher flash point,Alternative diesel fuel due to fuel having high cetane number, Low smoke emission due tooxygenated fuel, Ultra low sulphur fuel, Low environment impact due to high biodegradationfuel. The huge biodiversity of Indonesia provides more than two dozen of fatty-oil yieldingplants that may be exploited to produce biodiesel. Palm (Elaeis guineensis) is the mostpotential of these. Palm oil is now already produced and marketed in very large quantities,because it is edible and has a high harvesting yield (+/- 3 ton/hectare/year).In this study, the engine performance, exhaust gas emissions, and some of fuel properties weremeasured for fuels: biodiesel of Crude Palm Oil (CPO) and biodiesel of Refined BleachedDeodorized Palm Oil (RBDPO), and these fuels blended with diesel fuel.It was found that both of biodiesel fuels and their blended fuels with diesel oil shows thebrake specific fuel consumption (BSFC) was increased, but the exhaust emissions (CO, CO2,HC and smoke) were better compared to the diesel fuel.
