Compatibility of mid-level biodiesel blends in vehicles in Indonesia

This paper first reviews the effects of biodiesel on emissions of nitrogen oxides, carbon monoxide, hydrocarbons, and particulate matter in conventional vehicles. It compares the effects of using palm biodiesel and other biodiesel feedstocks, such as soy and rapeseed oils. The paper then reviews the effects of biodiesel on vehicle materials, including components of the fuel supply, engine, and exhaust system. These effects include corrosion and wear of metallic components, degradation of elastomers, and deposit formation in filters and fuel injectors. The implications of the impacts of biodiesel on vehicle emissions and materials are discussed in the context of Indonesia specifically.
