Abstract
The article presents the results of an experimental study of the spraying of superheated water through channels (holes in the nozzle), characteristic of piston internal combustion engines, under different initial conditions. The paper briefly discusses the advantages and disadvantages of modern fuel systems of diesel engines. The process of explosive boiling is briefly described with reference to the diesel fuel system. The results of spraying superheated water through a cylindrical channel and through a nozzle of an operating diesel of dimension 21/21 are presented. The scheme for the implementation of the diesel fuel system with the use of the explosive boiling effect is proposed. Preliminary estimates have shown that the use of such a fuel system will lead to an increase in the reliability of the elements forming the combustion chamber of the engine, reducing the specific fuel consumption to 2 % and reducing the amount of harmful substances in the exhaust gases by an average of 12 %.
