EN The emulsion is a mixture of two or more insoluble liquids. Microemulsion is the emulsion with particles dimension in a range of one micrometer 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 adverse 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 to improve 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 also 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. The performed analysis and investigation is the first stage of work, which is aimed to reduce emissions of PM and NOx simultaneously. It seems that the simultaneous reduction in emissions is possible through the usage of a stable emulsion, i.e. water-fuel microemulsion.
