Description

The utility model relates to lubrication systems, in particular to the lubrication systems of internal combustion engines.

A known lubrication system of an internal combustion engine (ICE) containing the main and auxiliary oil lines, while the main oil line includes a turbocharger, an oil pump, an oil-water heat exchanger, a coarse oil filter and an oil pumping unit, and a centrifugal filter pump is included in the auxiliary oil line, centrifugal filter and fine filter; in the main oil line an additional fine oil filter is installed, the input of which is connected to the filter output ra coarse or to the output of the oil pump, and an output - to the input of a turbocharger mounted on the internal combustion engine [Patent №46047, IPC F01M 1/10, 27.12.2004].

The disadvantage of this lubrication system of an internal combustion engine is the inability to determine the residual life of the engine without additional diagnostic work.

The closest in technical essence to the proposed utility model is the lubrication system of an internal combustion engine, comprising a main oil tank, a gear oil pump, an oil filter, a central inlet cover, a pressure sensor continuously and remotely measuring the oil pressure in the lubrication system, a control unit, a storage device and a pressure sensor measuring the oil pressure in the lubrication system after a set time interval and transmitting the received information to the storage device through the block to control, while the main oil tank is connected to the engine through an oil pump, pipelines and a central supply cover, and the pressure sensor is connected to the mentioned pipeline [Patent No. 44749, IPC F01M 11/00, 11/18/2004].

The disadvantage of this lubrication system of an internal combustion engine is the low accuracy of determining the residual life of the engine.

The technical result consists in increasing the accuracy of determining the residual life of the engine.

The technical result is achieved by the fact that the lubrication system of the internal combustion engine containing the main oil tank connected to the engine through a gear oil pump, oil filter, pipelines, a pressure sensor connected to the pipeline, continuously measuring the oil pressure in the lubrication system and transmitting the received information to the storage device through the control unit, the system is additionally equipped with three pressure sensors installed at the beginning, middle and end of the engine oil line, a unit and dikatsii coupled to the memory, the temperature sensor is installed between the oil filter and a pressure sensor connected to, the conduit, and the control unit is adapted to reprogramming.

The lubrication system of an internal combustion engine is illustrated in the drawing, where the figure shows its general view.

The lubrication system of the internal combustion engine contains a main oil tank 1 connected to the internal combustion engine 2 through a gear oil pump 3, an oil filter 4 and pipelines 5. A pressure sensor 6 connected to the pipeline 5 continuously measures the oil pressure in the lubrication system and transmits the received information to the storage device 7 through the control unit 8. Three pressure sensors 9 installed at the beginning, middle and end of the oil line 10 of the internal combustion engine 2. The display unit 11 is connected to the storage them device 7. The temperature sensor 12, installed between the oil filter 4 and the pressure sensor 6, is connected to the pipe 5. The control unit 8 is made with the possibility of reprogramming.

The lubrication system of an internal combustion engine operates as follows. The control unit 8 enters the initial viscosity of the oil, the parameters of the functional dependence of the viscosity of the oil on temperature. When the crankshaft of the internal combustion engine 2 rotates, the gear oil pump 3 takes oil from the main oil tank 1 and pressurizes it through pipelines 5 through the oil filter 4 to the oil line 10 of the internal combustion engine 2 to the friction parts of its mechanisms. From pipeline 5, oil flows to a pressure sensor 6, continuously measuring the oil pressure in the lubrication system and transmitting the received information to the storage device 7 through the control unit 8. From pressure sensors 9 connected to the beginning, middle and end of the oil line 10 of the internal combustion engine 2, information is received through the control unit 8 to the storage device 7. Between the filter 4 and the pressure sensor 6, a temperature sensor 12 is installed, information from which also goes to the control unit 8. During operation, If internal combustion occurs, gradual wear of the rubbing parts of the engine mechanisms occurs, while the oil pressure in the oil line 10 will decrease. Every day, at set times, immediately after start-up and after warming up the internal combustion engine to operating temperature, the control unit 8 captures the information of the pressure sensors 9 and the temperature sensor 12 and transfers it to the storage device 7. After processing the data of the storage device 7, a pressure reduction relationship is established at the beginning, middle and end of the oil line 10 of the internal combustion engine 2 from the time of its operation. Based on this dependence, the residual life of the engine is determined, which is transmitted to the display unit 11.

The proposed lubrication system of the internal combustion engine provides high accuracy in determining the residual life of the engine, which allows more economical and efficient use of equipment.

A prototype of the lubrication system of an internal combustion engine is manufactured and tested in the laboratory of the department of technical service, mechanics and electrical engineering of the Federal State Budget Educational Establishment of Higher Education Omsk State Autonomous Okrug.

Using the proposed lubrication system of an internal combustion engine increases the accuracy of determining the residual life of the engine, which increases its turnaround time by 25-30%.
