THE CHARGE AIR COOLING SYSTEM OF THE SHIP'S INTERNAL COMBUSTION ENGINE BY THE THERMOPRESSOR WITH OVERHEATING WATER INJECTION

Abstract

The scheme solution by using thermopressor as the part of three-circuit cooling system of the medium-speed marine engine is analyzed. The way to improve of the efficiency of the water spray process in the thermopressor is considered. Using of overheated water injection in the thermopressor of the charge air cooling system makes it possible to increase the relative increase air pressure at the outlet thermopressor to 5...8 %, with a corresponding reduction in the power of the engine turbocharger.
