2 Stroke Diesel Engine Jacket Cooling Water System Marine Learning Fresh water & sea water cooling system for marine diesel engine. cooling of engines is achieved by circulating a cooling liquid around internal passages within the engine. the cooling liquid is thus heated up and is in turn cooled by a sea water circulated cooler. without adequate cooling certain parts of the engine which are exposed to very. Cooling system maintenance ensures proper water flow in the engines. without proper water flow, the engine loses cooling efficiency. if the engine continues to operate inefficiently, overheating will eventually occur, which can lead to significant damage.
Marine Auxiliary Diesel Engine Cooling System Most newer marine engines use an enclosed cooling system. this means that there is a small tank on the top of the engine that uses a combination of fresh water and coolant. this fresh water is circulated through the engine and through a heat exchanger. the fresh water, in this system, absorbs the heat of the engine. Basically, all recreational marine diesels have heat exchanger cooling systems (that would be equal to your car’s radiator). instead of using air to remove the engines heat, the heat exchanger uses seawater as the cooling medium through a series of tubes with sea water on one side of the tube and hot coolant on the other. In a raw water system the water is drawn up through the seacock by the water pump. the water flows through the engine and directly out the exhaust. this cooler water absorbs heat from the engine to help keep it cool. most newer marine engines use an enclosed cooling system. this means that there is a small tank on the top of the engine that. Most newer marine engines use an enclosed cooling system. in an enclosed system, there is a small tank on the top of the engine that uses a combination of fresh water and coolant. the fresh water is circulated through the engine and through a heat exchanger.

Most newer marine engines use an enclosed cooling system. in an enclosed system, there is a small tank on the top of the engine that uses a combination of fresh water and coolant. the fresh water is circulated through the engine and through a heat exchanger. Today almost all new marine engines use the closed cooling system design. these systems are pressurized, just like your car or truck. by increasing the pressure inside the closed part of the system, the boiling point of the coolant is enhanced. for every pound of pressure added, approximately 3° f can be added to your engine’s operating. The ht cooling water system is circulated by electrical cooling water pumps, one in service and one on standby. during standby, the dg is kept warm by the circulating system from the dg in service. when me is stopped, it is kept warm by ht cooling water from dg. if this is insufficient, the water may be heated by a steam heated fw heater.
