REDUCTION OF FUEL CONSUMPTION IN FISHING FLEET ENGINES

Abstract

The article presents the results of tests of high speed diesel engines used in fishing boats and vessels. The reduction of unit 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 catalyst works more effectively when fuel is turbulized in crossing fuel passages made in a part of the injector needle. Preliminary fuel treatment results in the average reduction of unit fuel consumption of those engines by 8%, while toxic emission of carbon and  nitrogen oxides drops by 15%.
