Abstract

This paper deals with the use of straight vegetable oil as fuel for compression ignition engine applied to distributed electric generation. It was studied three typical oils from southern of the Brazil, soybean oil, sunflower oil and tung oil. For this purpose it was designed and assembled a conversion kit that allows the use of the selected oils directly in the engine. The kit preheats the fuel to a temperature where their physical properties, mainly viscosity, reaches the diesel oil levels. This kit is electronic controlled and it was used standardized measurements of some physical properties of the fuels, for the design of their control software. The straight vegetables oils, its blends 50/50 v/v with petrodiesel fuel and neat petrodiesel fuel were tested in dynamometer bench. It was obtained results of brake power, torque, specific fuel consumption and emissions as function of the rotation of the engine. The discussions about the results in terms of efficiency first law showed the technical feasibility of the using of straight vegetable oils and the effectiveness of the developed conversion kits.

Most of these (and others) have already been tested as neat fuels for CI engines. Table 1 lists oil producing crops that have been tested as straight vegetable oil (SVO) fuel in CI engines in recent years. The references for their use as biodiesel far outnumber those shown and are omitted. Vegetable oils present, comparatively to diesel oil, lower LHV (from 10% to 17% lower, leading to lower energy release per mass burned), higher viscosity (leading to poor atomization), higher boiling temperatures (delaying evaporation and formation of a combustible
