Abstract
Nowadays, demand for more efficient energy increased due to the green technology as one of the prominent research areas. In order to improve the exhaust emission from the diesel engine, researchers have found an alternative fuel which known as water-in-diesel emulsion fuel. It is a promising way that could fulfill such demand because it can simultaneously reduce harmful emissions; Nitrogen Oxides, Particulate Matter and Hydrocarbon, and improve combustion efficiency of diesel engine. W/D emulsion fuel is a mixture of water and diesel with the presence of surfactant. However, the stability and high dependency of surfactant are the main concern in producing emulsion fuel. High cost of surfactant has restrained the emulsion fuel to be commercialized. Hence, with the aim to remove the dependency on surfactant to produce emulsion fuel, this research has been conducted in order to come out with a mixing system design which known as Real Time Emulsion Fuel Supply System (RTES). It is a machine that combines two types of mixers; high shear mixer and ultrasonic mixer in one unit and able to emulsify the water and diesel fuel without adding any surfactant. Throughout the RTES design process, there are design objectives that are considered. Besides, there are also some regulations and constraint that needs to be consider during the component selection.
