Description

The utility model relates to devices in lubrication systems and can be used to control the oil level in hydraulic tanks, crankcases of internal combustion engines, in particular, used on self-propelled machines for technological processing of aluminum electrolysis cells.

A known system where a ruler is used to determine the oil level in the crankcase of an internal combustion engine, consisting of a dipstick made with the possibility of its installation in the crankcase of the engine, as well as with the ability to control the oil level in its pan and equipped with upper and lower marks in the form of strokes . The probe is made in the form of a ruler, on which strokes with a scale are additionally applied between the indicated marks. The reference point coincides with the upper mark, and the end of reference coincides with the lower mark, the inscription “Top up, l” is made above the scale along the ruler, where the letter “l” indicates the measured value in liters (application for invention of the Russian Federation No. 2013157124, class G01F 1/00, June 27, 2015).

Serially manufactured engines have specially made holes for installing oil level sensors in the lubrication system.

The closest in technical essence to the claimed system is the system proposed for monitoring the oil level in the tanks of hydraulic systems, crankcases of internal combustion engines and other containers (USSR Author's Certificate No. 1557413, class. F16N 29/00, publ. 04/15/1990 ) The system uses a pointer containing an elastic transparent tube with a handle, made in the form of a loop from this tube. One end of the tube is equipped with a measuring scale - the minimum and maximum oil level marks, and the other end of the tube acts as a bypass channel. The pointer is equipped with a plug for fixing it in the opening of the oil tank. Oil level measurement is carried out as follows. In the initial position, in the cavity of the transparent tube, the oil level is set corresponding to the oil level in the tank. When the oil level changes, a change in the air volume in the cavity of the transparent tube is provided due to the presence of a bypass channel.

The prototype has its drawbacks: when using a dipstick to control the oil in an internal combustion engine, dust, dirt or abrasive particles are likely to get into the engine lubrication system, especially when the machine is operating in dusty environments, for example, in aluminum electrolysis cases. The engine lubrication system is not tight, dirt can enter through the dipstick hole when checking the oil level or through the filler neck when adding oil.

The objective of the utility model is to increase the reliability of the system and reduce the overhaul period.

The technical result consists in the development of a sealed oil filling and control system.

The technical result is achieved by the fact that in the system of filling and monitoring the oil level in the internal combustion engine, containing a device for determining the oil level and oil drain, according to the claimed solution, the crankcase is connected to a visual level gauge for monitoring the oil level according to the principle of communicating vessels, in addition, the crankcase It is connected to the atmosphere through a breather filter and has an oil drain plug when replacing, mounted on an extension cord and removed from the engine.

The system is clarified by an additional feature.

For refueling oil in the crankcase, for example, a quick disconnect connection is provided.

A useful model, its features, details and advantages can be understood from the description given with reference to the attached figure, illustrating an example of a useful model, where the figure shows a diagram of the system.

The list of structural elements: engine 1; visual oil indicator 2; oil filler cap 3 in engine 1; quick disconnect connection 4; sump 5; fitting 6; extension cord 7; breather filter 8; oil drain plug 9; tee 10; fitting 11 of the crankcase 5; sleeve 12; fittings 13 and 14 connecting the sleeve 12 with the filler neck 3 of the oil in the engine 1; fitting 15; extension cord 16.

In the system for monitoring the oil level in the engine 1, a closed type of visual oil indicator 2 is provided. The visual oil indicator 2 is made in the form of, for example, a transparent tube connected to the crankcase according to the principle of “communicating vessels”. The plug 3 of the oil filler neck 3 in the engine 1 is sealed, and for refueling and topping up the oil under pressure a quick disconnect connection 4 is provided. At the bottom of the crankcase 5 there is a fitting 6 for connecting the extension cord 7, with a quick disconnect connection fixed at the end 4. The quick disconnect connection 4 is made as one-way valve. The hole for the installation of the probe (according to the prototype), made in the crankcase 5 of the engine 1 is closed by a sealed plug (not shown in Fig.).

The internal volume of the engine 1 is communicated with the atmosphere of the air using a special filter breather 8 for fine cleaning of the air entering the engine and eliminating excess pressure or vacuum. To drain the used oil from the crankcase 5 of the engine 1, an extension cord 7 is provided, equipped with an oil drain plug 9 at the end. An extension cord 7 is connected via a tee 10 to the fitting 11 of the crankcase 5. The extension cord allows the waste oil to be drained in more comfortable conditions and prevents environmental pollution when changing the oil.

The upper part of the visual oil indicator 2 is connected by a sleeve 12 through the fittings 13 and 14 with the oil filler neck 3 to the engine 1. The visual oil indicator 2 is connected with the lower part through the nozzle 15, extension 16 and tee 10 to extension 7.

The disadvantages of the prototype are excluded by the fact that:

- the hole for installing the dipstick is closed by a sealed plug, and the oil level in the engine is controlled by the closed type of visual oil indicator provided for this;

- the oil filler cap is sealed, and the oil is filled and refilled under pressure through a quick disconnect (BRC) specially designed for filling and refilling;

- to communicate with the atmosphere of the internal volume of the engine, a special breather filter is installed for fine cleaning of the air entering the engine;

- to drain the used oil from the crankcase, an extension cord with a plug for draining the oil is provided. The extension cord allows you to drain the used oil in more comfortable conditions, and does not allow polluting the environment when changing the oil.

The operation of a closed level control system and oil filling in the engine is as follows:

Oil is refilled by a special device, for refueling, having a pump for creating pressure and having a return tip for quick-disconnect connection for refueling installed on the engine. When refueling the oil in the crankcase, the oil, according to the principle of communicating vessels, enters the visual indicator of the oil level, which is closed type and has a clear glass for visual control of the oil level. When refueling the maximum oil level, refueling is stopped.

To drain the used oil, the extension cord equipped with the oil drain plug is placed in the drain tank, the plug is unscrewed and the oil is drained, after which the plug is tightly screwed.

During operation or after engine shutdown, due to temperature differences, air either enters the internal cavity of the engine or, vice versa, is forced out of the engine. All air entering the engine passes through a breather filter having a degree of filtration of the required value, which ensures that the air enters the engine of the required purity and the engine is not contaminated.

The use of a fully enclosed system increases the reliability and life of the engine, especially in difficult, dusty conditions.

The pilot industrial application of the system was tested on self-propelled machines for processing aluminum electrolyzers, the system showed high reliability in operation and ensured an increase in the service life of engines before overhaul.
