IMPROVING THE EFFICIENCY OF HEAT EXCHANGE PROCESSES OF MARINE ENGINES BY OBTAINING BIMETALLIC BUSHINGS CYLINDER
Abstract
Considered some aspects of improving the efficiency of heat exchange processes in marine engines. Found that with the exception of indicator work took him there has been an increase in the efficiency of the engine at a constant level of internal losses. Determined that an increase in the thermal resistance of the heat re villas, with equal passed cooling heat cooperation Coley and other factors will require an increase in temperature of heat transfer between heat flow and heat-transfer receptive surfaces of the cylinder due to new knowledge ensuring surface temperature. The wall temperature is increased with increased thermal head is only possible at the expense of increasing the gas temperature in the cylinder. Increasing the gas temperature leads to ascending its heat content that increases efficiency of gas due to the growth of pressure in the cylinder. Incomplete combustion of fuel reduction and increase the temperature of the processes creates conditions for increase of effectiveness of processes of heat exchange of ship engines. Shows the positive effect of the proposed structural decision and their additive technology implementation.
