Researches of a combustion engine fuelled with a fuel-water microemulsion

The emulsion is a mixture of two or more insoluble liquids. Microemulsion is the emulsion with particles dimension in a range of one micrometre and smaller. Such a microemulsion of water and diesel fuel will create a novel quality and allows one to simultaneously achieve environmental and economic effects, as well as eliminate the ad-verse impact of normal emulsions, or adverse effects of water injection into the engine intake system or directly into the combustion chamber, as well as the sequential injection of water directly into the combustion chamber. Application of microemulsion of water and diesel to fuel diesel engine positively affects the combustion process through the catalytic impact of microparticles of water, and improves the process of preparation of the microemulsion injection into the combustion chamber as a result of water microparticles’ microexplosions. This article presents the investigation results of an internal combustion engine fuelled by an emulsion of water and diesel fuel and fuelled by emulsion of FAME and water. It therefore seems appropriate to a strong increase in the degree of dispersion of water droplets in the emulsion by applying the methods to obtain the size of water droplets on nanometric range. This should dramatically improve both the stability of emulsion and its influence on the chemical effects of combustion in diesel engine.
