Description

The invention relates to mechanical engineering and is intended to control the oil level in the crankcase of an internal combustion engine.

A device is known for maintaining the oil level in an oil bath, mainly in the crankcases of internal combustion engines (patent RU 1451293). According to the invention, oil is added from a make-up tank with air and oil cavities, separated by a level located above the oil level in the bath, through a valve installed in the oil pipe, the outlet of which into the bath is located below the oil level in it. The cavity is connected to the cavity of the bath above the oil level through a ball valve consisting of a seat and a ball placed in a transparent float chamber. Upon reaching the normal oil level in the crankcase, a ball floating in the oil coming from the crankcase into the chamber blocks the air supply to the make-up tank, and the oil refilling is stopped. The disadvantages of such a device include leakage of the valve and, therefore, low reliability of the device.

A device for maintaining the level of motor oil in the crankcase of an internal combustion engine (patent RU 2439340), containing a reserve tank of engine oil, hydraulic lines connecting the reserve tank and the crankcase, in accordance with the invention, the device is equipped with an uncontrolled hydraulic pump equipped with a drive mechanism from an internal engine combustion, while the hydraulic pump is connected to the crankcase through a throttle, adjusted to the standard volume of oil supply, and to the tank of the reserve volume of oil through the drain valve. The invention solves the problem of maintaining the optimum level of engine oil in the crankcase during operation of the internal combustion engine due to the constant replenishment of oil in the required volume, which corresponds to a given number of engine revolutions. This technical solution does not take into account additional factors affecting the oil consumption in the engine.

An object of the present invention is to provide an automatic engine oil level regulator for an internal combustion engine, which enables timely oil supply to the crankcase of an internal combustion engine to maintain an optimum oil level.

The technical result of the claimed invention is to reduce the likelihood of accidental damage to the bearings of the crankshaft and the cylinder-piston group of the engine.

The claimed technical result is achieved due to the fact that the engine oil level regulator for the internal combustion engine contains a reservoir for storing reserve oil, a flexible oil line connected to the tank, an oil level sensor in the crankcase, an electromagnetic valve located at the point where the oil line is connected to the tank, and also a regulator additionally contains an oil level indicator in the tank for storing backup oil and electric wires connecting the sensor, valve and indicator with the vehicle’s battery and the vehicle Istemi car.

The invention is illustrated in the drawing, which shows a diagram of a motor oil level regulator. The positions in the drawing indicate:

1 - engine crankcase,

2 - a tank for storing backup oil,

3 - oil level indicator in the tank,

4 - valve

5 - switch

6 - oil pipe,

7 - oil level sensor in the crankcase.

According to the invention, the engine oil level controller consists of a reservoir for storing reserve oil 2 with an oil level indicator 3 in the tank 2, an oil pipe 6, an electromagnetic valve 4, a float sensor 7 of an oil level in the crankcase, and electrical wires connecting the sensor 7, valve 4 and indicator 3 with a car battery and an on-board car system.

The regulator operates as follows. The dosing system is activated by the driver with the engine running and the vehicle standing. When the oil level drops below the lower mark on the dipstick, the sensor 7 gives a signal to the valve 4, which opens and the oil from the tank 2 enters the engine crankcase.

When the oil level reaches the upper mark of the oil dipstick by the signal of the sensor 7, the valve 4 closes and the oil supply to the crankcase stops. At the end of the oil in the tank 2, the indicator 3 gives a signal to the on-board system of the car and informs the driver about the need to add oil to the tank 2.

When the car is moving, the dosing system does not work, since the oil level in the crankcase is constantly changing.

Using the regulator allows you to avoid engine operation at an oil level in the crankcase outside the marks on the dipstick. This reduces the likelihood of accidental damage to the bearings of the crankshaft and the cylinder-piston group of the engine.

The existing experience of the device showed the exclusion of cases such as the release of oil through the breather and oil dipstick and overheating of the engine due to insufficient oil level.

The inventive oil level controller is universal for all vehicles equipped with an internal combustion engine. Depending on the model of the car, the dimensions of the device are changed and the sensors included in the regulator are adjusted.
