DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for automatically supplying a certain amount of lubricating medium and/or cooling medium to an engine which is arranged on an assembly pallet and has lubricating medium circulation and/or cooling medium in its body. This is for initial filling, and the #J engine is equipped with a connection port in the main conduit for each medium, and the connection port is connected to the connecting member of the assembled pallet through the connection conduit, and is connected to the filling station. is equipped with a corresponding connected member, which is automatically connected to the connecting member of the I11 vertical pallet and connected to the dosing device and the storage container through the supply line or also through the discharge line. Concerning the initial photonic device to which it is connected. .

Devices of this type are well known and are used, for example in internal combustion engine factories or compressor factories, to supply engines assembled on a production line with the required quantities before initial operation or even test operation in order to avoid engine failure. Installed to supply lubricating and/or cooling media. However, this well-known device is capable of reliably verifying whether each circulation within the engine is actually able to maintain or carry the media it accommodates with the correct amount to be verified, in accordance with its function. Despite the fact that filling is carried out independently and with monitoring only with respect to the weight of the lubricating and/or cooling medium supplied to each of the seven engines, in the subsequent initial operation. It has a defect that may cause engine failure.

It is an object of the present invention to improve the device according to the technology mentioned at the outset so that in a simple manner determinations regarding the function and status of the above-mentioned media circulation in the engine can be made.

This means that, according to the invention, in the filling station, on the one hand, a flow throttle is connected to the lubricating oil supply line, in which the engine is being filled with lubricating oil under pressure. The resulting pressure drop can be measured via seven pressure detectors connected upstream and downstream respectively, and on the other hand, a shutoff valve and a shutoff valve in the cooling medium discharge line are installed on the upstream side thereof. a pressure sensor located at is connected, and the pressure sensor is in communication with the evaluation unit, in which a setpoint value for the pressure detection signal can be inadvertently provided. This is achieved in that, by means of the evaluation unit, by comparing the pressure detection signal with its setpoint value, it is possible to determine whether the medium circulation is good or bad. By measuring the pressure drop across the constriction of the lubricating line, its injected weight can be determined in a simple manner during filling of the engine. This allows for example to complete 'fi-
Easily detecting defects in oil-lubricated bearing metals and similar parts without the need for more complex tests of the engine reduces the flow resistance of the lubricating medium being supplied to these defects This is possible because it has been confirmed that as a result of this, the pressure drop at the choke point increases.

By virtue of the shut-off valve in the cooling medium discharge line, the cooling circuit, in which the medium is supplied through the supply line at a defined, in particular constant pressure, is closed on one side, so that the shut-off valve upstream of the shut-off valve is closed. By comparing the pressure recorded by the pressure detector with the pressure on the supply side,
A simple watertight test of the coolant circulation in the engine is performed.

With the device 11 according to the invention, it is furthermore possible to determine the state or even the functioning of the above-mentioned media circulation in the engine, especially without the need for additional components or time, thereby making it possible to determine the functioning of the engine. The existence of these defects allows the 4s recognition of defects that may cause the engine to fail.

The lubricating oil reaches the heating container (19) from the oil tank through the pipe line (c) and the 70-gate valve connected therebetween, and the lubricating oil reaches the heating container (19) via a temperature measuring device or a regulating device (to). The temperature is maintained at a constant temperature, for example, gJo.

The heated next oil is passed through the pipe (to) to the heating container (
19) to the supply device equipped with a pump @).

The supply device type also has a built-in regulating valve (c) to maintain a constant pressure within the pipeline.

The excess oil controlled by the regulating valve (c) is returned via the line to the temperature measuring device in the heating vessel H or alternatively to the regulating device.

In order to fill lubricating oil into the internal combustion engine (21), at the start of filling, the appropriate amount dispensing piston in the rightmost position - determined by the switch or the stopper - must be opened with the pipe. It moves towards the left under the action of the force of air in the working cylinder side supplied through the valve (7), which closes the lubricating oil, and if the valve is opened - the lubricating oil flows through the pipe. It is supplied to the rotary valve (to) through the path f41. The rotary valve ω is in the position shown at the start of filling I, and in this case the lubricating oil is supplied to the crank drive lubrication via the supply pipe Q417 and the connecting pipe (7). The internal combustion engine (2) used for this purpose is supplied to the production threshold oil circulation. When filling with lubricating oil in this time range, the pressure drop that occurs at the throttle f511K is the pressure drop that occurs in the pressure detector [Co., Ltd.].

) is directly related to the condition of the lubricating oil circulation. The reason is that if the flow cross-section in the lubricating oil circulation is open at 1, which also falls within the previously given tolerance range, and a pressure drop that deviates from its target value occurs, then the flow in the lubricating oil circulation This is because it is possible to infer whether the resistance is large or small, and from this it can be inferred that, for example, a bearing meckle or something similar is missing.

The temperature measurement via the temperature sensor 57)' is performed by switching the rotary valve to the other switching position after the viscosity of the supplied lubricating oil has been filled with lubricating oil. As a result, the remaining lubricating oil is supplied to the crank chamber of the internal combustion engine (21) from the am discharge cylinder through the connecting pipe M (81) by cranking the housing before starting operation of the internal combustion engine.

A cutoff valve (branch), 11m, is connected to the cooling liquid supply pipe (17) and discharge pipe (lF4) for the receiver (connected member 03 of I21) in the middle thereof.

Through the line @, the heating container is connected to the pump heating of the supply device, and the return line on the discharge side is regulated at a constant level of 8E via the regulating valve a1. #! The pressure water controlled by the valve regulator returns to the heating inside the heating container or to the temperature regulating device 1161 housed in the housing through the pipe (to). The same applies to the cooling water which is returned via the discharge line (I6) and likewise returns to the heating vessel (■).

A pressure detection @a1) is connected to the cooling water flow path upstream of the shutoff valve of the discharge pipe line, and its measurement No. 48 is sent to the evaluation=Lnitz)% through the cable (company).

At the beginning of filling the internal combustion engine 12) with cooling medium, if the shutoff valve is not opened, the cooling water chamber is rinsed for a certain period of time. Wash away unbearable pollution. After the rinsing period, the shutoff valve end of the discharge line O@ is closed and a dynamic pressure is created in the cooling water circulation. This dynamic Ff is primarily given by adjusting the #valve adjustment unless there is a leak.

The actual dynamic pressure throughout the pressure sensor (2) is compared with the target value in the evaluation unit) (nl). This makes it possible to directly signal leaks in the cooling water circulation, which may possibly be present. .

In the figure, the possibility of draining water from the cooling water circulation after this watertight test is clearly shown; for this purpose, when the shut-off valve (to) is closed, the connection port (
Pressurized nitrogen is blown into the exhaust pipe 08) from 2), during which cooling water is discharged from the cooling water circulation of the internal combustion engine through the exhaust 7 lung σ lift. The discharge flange is connected to the feed pipe ff51 to the drain pipe OQ on the downstream side of the shutoff valve by a method not shown here, and it is possible to return the drained cooling water to the fully heated valley basin. .
