Description

The claimed technical solution relates to the field of internal combustion engines (ICE) and can be used both in transport and in stationary ICEs.

The prior art device Pat. No. 2122645 publ. 11/27/1998, in which the dipstick (oil level indicator in the engine crankcase) is installed separately in the engine block, and if the dipstick is carelessly installed or the seal is worn on the dipstick, an air-oil mixture and crankcase gases may break through into the atmosphere. When measuring the oil level (removing the dipstick), droplets of oil draining onto the surface of the soil, as well as rags used each time to wipe the dipstick, pollute the environment.

Known technical solution US Pat. No. 54633 publ. 07/10/2006, in which, as in the proposed technical solution, there is no separate fitting for the oil dipstick, and the hole for installing the dipstick is made in the fitting next to the pipeline of the engine crankcase ventilation system, which increases the convenience when measuring, but the system remains open and the above-mentioned disadvantages not resolved.

From the course of the ICE theory, it is known that the greater the wear of the piston ring-cylinder liner pair, the greater the number of crankcase gases from the cylinders break into the ICE crankcase, worsening its environmental properties. The control of the increase in the number of crankcase gases as a result of wear helps to prevent excessive wear of the piston ring-cylinder liner pair and improve the environmental properties of the internal combustion engine.

Device Pat. No. 2343445 publ. 01/10/2009. allows you to control the flow of crankcase gases, as well as the proposed technical solution.

The disadvantage of this device is the impossibility of its use in the process of daily operation, since its use requires the use of measuring capacity and overlapping the crankcase ventilation system.

The closest analogue is the device pat. No. 54633 publ. 07/10/2006.

The above disadvantages are eliminated by the proposed technical solution.

The objective of the claimed technical solution is to improve the environmental properties of ICE.

This task is achieved by the fact that the proposed device according to one of several versions contains a stationary pipeline of the engine crankcase ventilation system of Fig. 1, installed tightly on the outside on the fitting 2, located in the lower part (cylinder block) of the ICE 3 near the sump 4 with a certain oil level 5 and connected also hermetically with the fitting 6, through which crankcase gases and oil vapors enter the internal combustion engine 3 of figure 2.

The movable part of the proposed device, which is made as a whole or from separate elements, contains a float 7 located in a position corresponding to the oil level 5 in the pallet 4 and connected by stiffeners with a float 8. The stiffeners in section AA have the form shown in figure 3 and perform the function of guides that allow the floats 7 and 8 to move together inside the fitting 2 without distortions and jamming, as well as to pass crankcase gases and oil vapors in the direction shown by the arrows in figure 1. The radial dimensions of the float 8 must be larger than the inner diameter of the fitting 2, so as to prevent the moving parts of the device from lowering into the sump 4 in the absence of oil 5 in the sump 4 of figure 1. The float 8 is connected to the rod 9, having several stiffening ribs 10, providing unhindered movement of the rod 9 inside and along the axis of the pipeline 1, both in straight sections and in bends in which openings for the passage of crankcase gases and oil vapors are made. In FIG. four.

For visual control of the position of the rod 9, the pipeline 1 must be made transparent as a whole or with the installation of the insert with transparent walls in any place convenient for observation. For example, for a passenger car, at least the upper closest to the hood and close to the horizontal part of the pipeline 1 type C of Fig. 5 should be transparent. It is possible to use a remote monitoring system in which the moving part of the proposed device can be used as a sensor (the principle of flow around a float is widely used rotameters). Data can be displayed on the dashboard of a car, or fed into a recording device.

On the surface of the pipeline 1 of Fig.5. lines with the min and max positions for monitoring the oil level are plotted, and then along the direction of the crankcase gases and oil vapors there is a scale showing the degree of wear (technical condition) of the piston ring-cylinder liner pair, consisting of three zones of different colors:

zone A - green - engine operation allowed

zone B - yellow - engine operation is allowed

zone C - red - engine operation is prohibited

The proposed device according to one of several versions contains a stationary pipe of the crankcase ventilation system installed hermetically outside the fitting located in the lower part of the engine near the crankcase with a certain oil level in the sump and also connected tightly with the fitting through which crankcase gases and oil vapor enter the engine . The movable part of the proposed device, which, in various versions, is made as a whole or from separate elements, contains a float located in a position corresponding to the oil level in the pan and connected by stiffeners with a second float, which allow them to move together along the nozzle without distortions and jamming, as well as passing crankcase gases and oil vapors. The radial dimensions of the float connected to the stem, which is also a pointer, must be larger than the diameter of the fitting to prevent floats and stem from lowering into the crankcase in the absence of oil in the crankcase. For visual control of the rod position, the pipeline is made in whole or in part from a transparent material. Depending on the embodiment, a remote system is used for data recording, in which the moving parts of the claimed device serve as sensors.

The proposed device operates as follows.

When the engine is not running, the moving part of the device (floats 7 and 8 connected by stiffeners and rod 9 with stiffeners 10) under the action of gravity fall down into pan 4 and stop in accordance with the oil level 5 in pan 4, into which float 7 is immersed. this, for example, the edge of the stiffener 10 of the rod 9, which is extreme to the fitting 6, will indicate the oil level 5 in the crankcase 4 (between the lines min and max) of FIG. 5.

When the engine is running at any (selected) speed at idle (and when using the well-known remote control system and at operating modes under load) crankcase gases and oil vapors from the volume between the engine block 3 of the engine 3 and the sump 4 flow through the fitting 2 between the ribs stiffness connecting the floats 7 and 8, as shown by the arrows in figure 1 and, flowing around the float 8, raise it by a certain amount in the direction of flow. The stronger the flow, which determines the degree of wear (the technical condition of the piston ring-cylinder liner pair), the higher the float 8 will rise. Registering the position of the float 8 — over the surface, for example, the extreme surface of the stiffener 10 of the rod 9 will indicate the result on the scales, indicated by different colors of FIG. The operating modes in which the degree of wear of the pair of piston ring-cylinder liner is controlled is determined by the engine designer.

It is possible to manufacture the proposed device from non-metallic materials, for example, polyamide, which will simplify the process of recycling the engine.

The technical result provided by the given set of features is the tightness of the proposed device without oil and crankcase gases on the soil and in the atmosphere, timely information on the need for repair and simplification of the engine disposal process.
