Description

The invention relates to the field of military equipment, in particular to a lubrication system of an internal combustion engine.

Closest to the invention is an engine lubrication system designed to accommodate a transportable supply of oil and supply it under a certain pressure to the rubbing parts of the engine in order to reduce their wear and remove heat from them. (See Object 172 A. Technical Description and Operating Instructions. Book 2. Military Publishing House, 1989, p. 322, Prototype).

The engine lubrication system includes: a main oil tank, a gear oil pump, an oil filter, a central oil supply cover, a pressure sensor continuously and remotely measuring the pressure in the lubrication system.

The engine lubrication system is a reliable system that ensures the normal operation of the engine, but has several disadvantages: inaccurate determination of the pressure in the system, lack of information about pressure changes in the lubrication system during engine operation.

The objective of the present invention is the collection and storage of information about pressure changes in the engine lubrication system in automatic mode in order to predict the residual life of the power plant.

This problem is solved due to the fact that the lubrication system of the internal combustion engine containing the main oil tank, gear oil pump, oil filter, central supply cover, sensor

pressure, continuously and remotely measuring the oil pressure in the lubrication system, characterized in that it is equipped with a control unit, a storage device and a pressure sensor measuring the oil pressure in the lubrication system after a set period of time and transmitting the received information to the storage device through the control unit, the main oil tank is connected to the engine through an oil pump, pipelines and a central supply cover, and a pressure sensor is connected to said pipeline.

The invention is illustrated in figure 1, where: 1 - the main oil tank, 2 - the gauge of the electric gauge, 3 - gear oil pump, 4 - the oil filter, 5 - storage device, 6 - pressure sensor, 7 - the cover of the Central oil supply, 8 - block management.

Figure 1 presents the pressure control device in the lubrication system of an internal combustion engine.

The main oil tank 1 serves to accommodate and transport the oil necessary for the operation of the engine. It is a container welded from stamped steel sheets. The main oil tank is structurally placed in front of the gear oil pump and connected to it by a hydraulic pipe.

Unlike the prototype, the pressure sensor 2 is designed for discrete measurement of oil pressure in the engine lubrication system. It is a cylindrical device that measures the change in pressure in the lubrication system and transmits information through the control unit to the storage device. It is installed in parallel with the pressure sensor 6 on a single pipeline. Pressure sensor 2 is more sensitive to pressure changes in the lubrication system. Installation of the pressure sensor 2 allows you to discretely, at certain intervals, measure the pressure in the engine lubrication system and transmit the received information to the storage device through the control unit. This makes it possible to obtain information about the process of changing the pressure in the lubrication system and to construct graphs, tables, monograms from the data obtained. Subsequently,

comparing the obtained data with tabular, we have the opportunity to predict the process of pressure changes in the future and, therefore, to determine the residual life of the power plant. This will maximize the resource of the power plant. Structurally, the sensor is connected at one end with a hydraulic pipe to the cover of the central oil supply, and at the other end with electrical wires to the control unit.

Gear oil pump 3 is used to continuously supply oil to the cover of the Central oil supply with the necessary pressure and in the appropriate quantity. It is a gear type unit with three pairs of gears located in a common housing in one horizontal plane. Structurally, it is placed between the oil tank and the filter and connected to them by hydraulic pipelines.

The oil filter 4 is designed to clean the oil entering the rubbing parts of the engine, and is a cylindrical glass cast from an aluminum alloy in which the filter elements are located. At one end, it is connected to the cover of the central oil supply, and the other to the gear oil pump via hydraulic pipelines.

In contrast to the prototype, the system is equipped with a storage device 5, which is designed to receive information from pressure sensor 2, convert this signal and place it in a memory cell. It is an electronic unit that converts the signal from pressure sensor 2 into an appropriate form and records the converted signal in a memory cell of the information carrier. The installation of this device is significantly different from the prototype in that it allows you to have information about the pressure in the engine lubrication system, not only at a given time, but also for a certain period of time. This makes it possible to follow the process of pressure change at a certain operating time of the power plant, so that it is possible to predict the process of pressure change in the future and, therefore, determine

residual life of the power plant. The storage device is structurally located behind the control unit and connected to it by electric wires.

The pressure sensor 6 standard, installed on the prototype, is designed for continuous remote measurement of oil pressure in the engine lubrication system. It is a cylindrical device that measures the change in pressure in the lubrication system and transmits information to the pressure gauge. The sensor is located between the cover of the central oil supply, connected to it by one end with a hydraulic pipeline, and the other end with a gauge indicator by electric wires.

The cover of the Central oil supply 7 is designed to ensure the supply of oil under the required pressure to the shank of the crankshaft. It is an aluminum cover with holes for supplying oil. Structurally, it is located on the shank of the engine crankshaft and is connected to the oil filter by a hydraulic pipe.

In contrast to the prototype, a control unit 8 is installed in the system, which is designed to control and coordinate the actions of the pressure sensor 2 and the storage device 5. It is a circuit diagram with the necessary control elements. The control unit 8 is located between the pressure sensor 2 and the storage device 5 and provides power to the storage device, as well as starting and stopping the time relay. Thanks to the use of this control unit, a time relay is started, which with a frequency of 5 m / h of operation of the power plant closes the power circuit of the contactor, which in turn closes the power circuit of pressure sensor 2 and memory 5. Information is transferred from pressure sensor 2 to memory device 5, after which the circuit breaks. The control unit is placed between the pressure sensor 2 and the storage device 5 and connected to them by electrical wires.

The lubrication system of an internal combustion engine. When the engine crankshaft rotates, the gear oil pump 3 picks up

oil from the main oil tank 1 and pressurizes it through the oil filter 4 to the cover of the central oil supply 7, from where it flows to the rubbing parts of the engine. In the cover of the central oil supply through drilling, the oil flows through the pipeline to the pressure sensors 2 and 6. From the sensor of the electric gauge 6, the information goes to the gauge pointer on the driver’s shield. Thanks to the control unit 8, information is transferred from the pressure sensor to the storage device, converted into the corresponding signal, and placed in the memory cell.

In case of wear of the elements of the crank and gas distribution mechanisms, the oil pressure in the lubrication system will change.

In this proposal, in addition to the standard sensor of the oil pressure gauge 6 of the oil pressure in the lubrication system, an additional device is connected to the engine lubrication system, consisting of a pressure sensor 2 and a storage device 5 connected by a control unit 8.

At a certain point in time (after 5 m / h of engine operation), the pressure sensor 2 detects the oil pressure in the lubrication system and transmits this information to the storage device 5. After processing the data of the storage device, it is possible to establish the dependence of the pressure drop in the engine lubrication system on the running hours.

The design of this device provides, based on the data on pressure changes in the engine lubrication system, obtained from the storage device, a graph. Using the resulting schedule, we are able to predict the process of pressure changes in the future, and, therefore, determine the residual life of the power plant. This will maximize the resource of the power plant and prevent premature sending for repair, and also does not require time for diagnostic work and the use of expensive diagnostic tools.
