OIL CIRCULATION SYSTEM FOR PRE-HEATING, LUBRICATION AND COOLING SYSTEM USED IN INTERNAL COMBUSTION ENGINE AND INDUSTRIAL EQUIPMENT Russian patent published in 2023 - IPC F01M1/02 F01M5/00 F01M5/02 F01M11/00 F02N19/00 

FIELD: mechanical equipment.

SUBSTANCE: invention provides a preheating, lubricating and cooling system in which oil of an internal combustion engine, industrial equipment or a vehicle is used as a preheating agent. The operator supplies the oil most optimized for operation of equipment under load by means of a preheating system that is separated from the oil line system, and the oil supply circuit uses the existing oil line system circuit, so that in cold or hot seasons, preheating and operation under load are facilitated, while normal operation is possible even in case of an immediate stop after operation. The preheating, lubrication and cooling system contains an oil supply device, including an oil sump, a primary heater, a secondary heater and a circulation pump, as well as a controller designed to control the operation of the oil supply device, a power supply, a control unit that includes a panel to control the operation controller and an information display unit designed to display a temperature gauge.

EFFECT: facilitated pre-heating or operation under load.
