COOLING SYSTEM FOR INCOMING GAS AND EXHAUST GAS OF MARINE DIESEL ENGINE, WHICH IS SUPPLIED TO INLET Russian patent published in 2012 - IPC F02G5/02 F02B29/04 F02M25/07 

FIELD: engines and pumps.

SUBSTANCE: cooling system for incoming gas - pressure air and exhaust gas of marine diesel engine (1), which are supplied to the inlet, includes the following: exhaust (3), suction (5) and recirculation (4) pipelines, damper (11), waste-heat boiler (2), absorption refrigerating machine (31), user of refrigeration (12), control unit (24), temperature (23) and load (21) sensors, position sensor (84) of damper (11), supply and control elements of heat carriers and cold carriers, heat exchangers of exhaust gases (7) and incoming gas (6) - pressure air. Heat exchanger of exhaust gases (7) is installed in recirculation (4) pipeline. Heat exchanger of incoming gas (6) is installed in suction (5) pipeline. Heat exchangers of exhaust gases (7) and incoming gas (6) have the possibility of being connected to absorption refrigerating machine (31). Cold carrier can be supplied to heat exchangers (7, 6) through electronic three-way valves (18, 19) depending on diesel engine (1) load.

EFFECT: increase in the amount of the air supplied to cylinders, and decrease of temperatures of working cycle and heat loads of diesel engine at its forcing as to pressure charging.
