Abstract
Diesel fuel is a liquid fuel, operates in diesel engine and has higher viscosity than gasoline. Diesel fuel is usually used as a fuel for motorized vehicles such as buses, trucks, trains, tractors and other heavy equipment as well as military vehicles. However, the use in diesel fuel can cause some pollutants such as, CO, HC, NOx, and particulate matter. Therefore, it is important to reduce some emissions by using alternative additives into diesel fuel. One of the methods in increasing fuel property is bio-water diesel emulsion. The purpose of this study is to review some findings in bio- water diesel emulsion in several studies. Therefore, a good percentage in water, fuel and additives can be concluded. In this study, bio-water diesel emulsion can reduce some emissions compared to diesel fuel. This occurs due to the micro-explosion phenomenon which can accelerate the decomposition of water droplets in the fuel. The study shows that 20% water mixture will result in better fuel combustion and reduced emissions. It is concluded that bio-water diesel emulsion can be an alternative fuel for replacing diesel fuel because it is environmentally friendly and has a better performance in the engine.
