Abstract
Biodiesel has been known as a prospective alternative diesel fuel because of its environmentally friendly and renewable resources. In Indonesia, palm is the most potential plant that can be exploited to produce biodiesel in the near future. Palm oil plantation in Indonesia has been grown rapidly since early 1980s. Recently, the palm oil production in Indonesia reaching over 10.68 million tons/year, due to the total area of oil palm plantation over 4.9 million hectares. In this study, the engine test bed procedure for an DI diesel engine injector nozzle coking test was adapted for neat biodiesel fuel of Refined Bleach Deodorized Palm Oil (RBDPO), and also for blended with diesel oil fuel. In addition a road test diesel engine vehicles using blended diesel oil and palm biodiesel fuel. In 2200 km fleet road test with 2 passenger cars an 2 trucks, the performance of petrodiesel fuel blended with 10% RBDPO (refined bleach deodorized palm oil) were compared with the performance of neat petrodiesel fuel. Parameters evaluated before and after road test were fuel consumption, exhaust gas emissions, fuel injection equipment, and engine lubricant.
