Delivering water to cylinders is a means of restricting the emergence of nitrogen oxides in the combustion process in SI engines. In consequence of feeding the engine with fuel-water emulsion with simultaneous decrease of nitrogen oxides in the exhaust gases, there occur changes in the concentrations of: carbon oxide, hydrocarbons, solid particles, and also changes in the basic indexes of engine work. The values of these changes depend in large degree on the assumed method of producing emulsion. Depending on the method applied there exists a definite set of control parameters characteristic for each method, whose values of particular parameters determine the properties of emulsion produced. One of these parameters is the temperature of, essential insomuch as it can be controlled in a simple way. The work presents the results of research on the effect of temperature of fuel-water emulsion produced in a helicoidal agitator on its properties, essential from the point of view of NOx emission load in the exhaust gases.
