Internal combustion engines, which run on hydrocarbon fuels, experience difficulty upon engine start-up in extreme cold weather. As ambient temperature decreases below the fuel cloud point and beyond, paraffin form in the fuel and eventually clog the fuel filter. This problem becomes more pronounced when the engine in question is a Diesel and the fuel utilized is biodiesel. As an alternative fuel source, biodiesel has many advantages; however its cold weather performance is worse than even conventional diesel fuel. As biodiesel becomes more integrated into the world’s energy usage, one of the systems within a Diesel engine requiring further investigation is its fuel conditioning system. This paper describes current research aimed at the development of a fuel conditioning system that utilizes several technologies while decreasing the amount of electrical energy required for operation. The system utilizes a eutectic-thermoelectric (E-TE) combination which consists of a eutectic compound based latent heat storage device with adjacent thermoelectric elements to transfer heat from within the engine into the fuel filter, thus diminishing the amount of electrical energy typically required for the fuel conditioning process. Simulations of the E-TE system are conducted while operating within three different modes (start-up, heat storage, and electrical energy generation), while a supervisory controller distinguishes between desired operational status. The research activities and findings reported within this paper include development of a representative E-TE system model which consists of several components including a set of control laws, and a supervisory system. Model development and preliminary results for the phase one model are discussed herein.
