Abstract

The research aimed to obtain the impact of the branched fatty acid ester use as blending biodiesel towards physical properties, engine performance and exhausted emission. This was a laboratory research consisting of testing of exhausted gas emission using Diesel Oil, Palm Biodiesel (B100), and Palm biodiesel blending with branched fatty Acid Ester (Bio-Plus). The result of the research were indicates that the physical properties of Bio-Plus is very different from the physical properties of B100, and diesel fuel. A significant difference can be seen in the value of the cetane number, kinematic viscosity, and heat value. Cetane number and kinematic viscosity of Bio-Plus is higher than the B100 and diesel, but heat value of the Bio-plus is lower than the B100 and diesel. Performance diesel engine with fuel Bio-plus better than the B100 and diesel. Use of Bio-plus can reduce exhaust emissions, especially NOX emissions were detected in the form of NO2 and COX emissions.
