Influence of chosen parameters of water fuel microemulsion on combustion processes, emission level of nitrogen oxides and fuel consumption of CI engine

The microemulsion is the emulsion with dimension of molecules approx. micrometre and smaller. Such microemulsion of water and diesel oil creates new quality and lets on obtainment ecological and economic of effects, as well as eliminates the disadvantageous influence common emulsions, or unprofitable effects of the injection of water to inlet system of the engine, direct to combustion chambers, as well as the sequential injection of water direct to combustion chambers. The essence of apply of the microemulsion is also improve catalytic influence of small molecules of water on combustion process, what, beside decreasing temperature combustion gases, influences both emission level components of toxic combustion gases, as and the level of the specific fuel consumption. The paper presents different ways of microemulsion production, novel way of microemulsion production, which does not demand apply of mixers and suffers obtainment of microemulsion with the volumetric content of water in diesel oil do 40% under conditions of laboratory and stabile the microemulsion with content of water in diesel oil to 25%. Results of laboratory research involving basic parameters of the microemulsion and engine researches with measurements emission ingredients of toxic exhaust gases and fuel consumptions are presented involving basic parameters of the microemulsion and engine researches with measurements emission ingredients (NOx, soot, fuel consumption) of toxic exhaust gases and fuel consumptions are presented in the paper.
