The article presents the results of tests of self ignition high speed engines used in fishing boats and vessels. The reduction of specific fuel consumption and exhausts toxic emission was possible by implementing preliminary fuel treatment that takes place directly in the fuel injector. containing catalytic material. The reduction of the nitric oxides emission level in exhaust gases has been obtained by means of preliminary fuel chemical treatment which is based on the use of heterogeneous catalyst and spirally shaped turbulization canals on the atomizer needle. Turbulizing process as well as homogenization of flowing fuel is carried out at fuel flow in the passages situated on the non-operating needle part, while both crossing passages in the form of left-hand and right-hand thread (Y version) and crossing grooves on the entire surface of the 2 needle (X version) may constitute the form of the said passages. Preliminary fuel treatment results in the average reduction of unit fuel consumption of those engines by 8%, while toxic emission of nitrogen oxides drops by 15%.
