DE4427414A1 - Lubricating oil circuit suitable for various engines - Google Patents

Abstract

The suction equipment is mounted on the oil sump, and the suction is applied to the area above the piston rings. Oil is fed in by an electrically driven pump which is controlled by a potentiometer via a central computer chip which also controls the suction equipment. The required data for the control are obtained from a prototype engine of similar construction. After optimum adjustment on a test bed, the data are incorporated in production engines. The outlet of the air from the suction equipment is fed to the engine exhaust in which an additional filter and catalytic converter can also be mounted. After final assembly of a production engine, oil lines are cleaned e.g. with compressed air.

Description

It is the engine oil circuit from the patent application P 43 26 119.1 in an improved embodiment described and patent pending.

The technical improvement is based on the optimal Separation of the lubricating oils by the corresponding one Reduction of the mechanics of a prior art corresponding industrial vacuum cleaner.

After the trial run, the oil intake channels are connected to the Piston rings cleaned with compressed air, including the suction head is dismantled, as the expert knows.

This engine oil circuit is also for modified, so suitable two-stroke. For this engine oil circuit should be a state of the art Industrial vacuum cleaner with liquid separation accordingly be made smaller.

This suction head is placed around an oil tank Generate negative pressure, which via the oil return lines Sucks off the excess oil over the cable rings.

At the bottom of the oil tank is a potentiometer Oil feed pump attached, which is the oil for lubrication of the piston delivers.

Every turned engine with this oil circuit, points the oil lines to the in the patent application P 43 26 119.1 described positions on.

The discharge of the exhaust air from this suction head leads to that Exhaust end.  

Above the lower, because the upper piston dead center is turned hot when the piston gives way to the expanding gases has made the upper piston dead centers are above the Piston rings, the oil supply lines and return lines, which in the oil tank, in which the suction head with Liquid separator provides the necessary negative pressure. One lies above the oil inlet channels on the cylinder walls the crankcase cast oil retaining ring, which with which then forms a small oil reservoir at the top of the piston, in which the oil suction channels are located.

Otherwise, I refer to the claims.  

To reiterate the peculiarity of this technology coming back I have to emphasize again that the newest and best industrial vacuum cleaner construction not known can.

Nevertheless, I refer to this state of the art the filing date, with emphasis on avoiding Excretions of liquid, namely oil in the exhaust air, which leads into the exhaust.

As already mentioned after the catalyst, if available. It can of course any number of oil intake and -Injection channels are attached.

As the oil gets hot, it is necessary to switch between the Oil intake duct and the liquid collection tank of the reduced industrial vacuum an oil cooler with oil filter to assemble.

At this oil cooler, if available or necessary, by means of Compressed air at service intervals also the oil intake duct cleaned. The different piston shapes do not arise finally from the various forms of my design Piston valve engine. Even with two-stroke gasoline engines Known nasal piston.

My request for protection relates to the state of the art on the filing date.  

The dimensions of the industrial vacuum construction should be based on the amount of oil to be managed is calculated depending on the type of engine be what I do not know at this point for known reasons is possible.

In the patent application P 43 26 119.1 only one of generating negative pressure written on the required Technology is deliberately not considered because the Priority should be exhausted.

The two-stroke gasoline version remained unmentioned in the relevant Share.  

As already described in the application, this should Registration coped with the lubrication of various engines will.

This registration is misleading as it is a division or Elimination from patent application P 44 26 985.4 emerges. A similar application was made in an earlier application Technology already for my piston valve engine described.

It was not conscious of the liquid suction received. This is registration P 43 26 119.1, and the different piston shapes refer to these types of engines, as is the case with two-stroke Gasoline engines also exist or were in use. The state of the art results from the filing date. So by citing this example and with it associated reduction of this machine part also the Inventiveness can be achieved.

Before, namely when registering P 43 26 119.1, you should go here only a corresponding negative pressure can be generated.

However, this application relates more to the two-stroke Ottoversion, characterized in that this also The engine is upside down and has encapsulated bearings.  

Because the lubricating oil gets hot in this version, it should go through an oil cooler, which is between the oil suction channels and the Oil tank lies, to be cooled.

If extremely reduced steam engines or the like are patentable, so are scaled down Industrial suction constructions, which are also liquids separate from the exhaust air.

As from the drawing of patent application P 43 26 119.1 nothing changes in the actual engine. Only with a two-stroke engine can different design-related changes occur, which improve of the exhaust gas are necessary, characterized in that with a direct injection is worked, the engine expediently during the running-in phase, because of the resulting chips (metal chips) is turned and with a Petrol / oil mixture is operated with a carburetor. Thereby prevents the lubrication from being affected. in the The catalytic converter is attached to the exhaust Trial operation is not connected.

After the catalytic converter, the exhaust air is reduced Industrial vacuum cleaner initiated.

The further developed features are the scaled down Industrial vacuum and the entire combination of features.

Claims (14)

Improved engine oil circuit for the piston valve engine, as he did for the first time after the technical break from the Additional application P 43 26 119.1 emerged and for modified two-stroke versions according to the "Otto" principle, in different designs. This is what it is about using the previous main application P 42 29 864.4-13 to make a new main application. Thereby characterized in that there is a drain of motor oil in the Exhaust completely excluded in this embodiment a correspondingly reduced oil or Liquid separation is used as in Industrial vacuum cleaners are used. So it's about thereby a reduced industrial suction construction, which the suction of the excess oil over the Piston rings takes over. One drawing is from patent application P 43 26 119.1 taken, different piston shapes, depending on Find engine type. This reversed engine has the oil supply and the Oil return line to the in the patent application P 43 26 119.1 described position, this also applies to the two-stroke Otto version. Control is also carried out as in application P 43 26 119.1 described and can with a potentiometer  be coordinated. Down on the scaled down Industrial suction tank, the oil from the electric operated oil pump, which is also extracted from the central Computer chip is controlled. The necessary data are based on the identical prototype won and after the optimal setting on the Test bench adopted in the respective series production. For a reduced industrial suction construction there is enough examples, such as those from Ruwac Industriesauger GmbH in Melle. The The exhaust air from this suction head leads to this Exhaust end. There is then the possibility of a catalyst or a Use oil filter in the right place. After final assembly of the series engine, the over the Piston rings lying, or located Oil supply lines and oil return lines after a trial run cleaned again. For example with compressed air. As is known to a person skilled in the art, the piston rings first scraped metal plans from the cylinder walls, which could clog the oil circuit. It would be advisable to do this at the required maintenance intervals to repeat what is possible by removing the suction head becomes. This also applies to various turned Two-stroke versions. The determination of the Protection scope expanded. And by preventing Oil discharges into the exhaust and thus the environment  clear technical improvement achieved. It will of course based on the state of the art and not on one certain construction persists. It is important to the best liquid separation and not to the highest suction power. The drawings relating to the prior art are intended in reduced in size and to the construction be used. On the previously named manufacturer of such devices can and I don't want to commit myself because of the state of the art. The drive of the suction head used should be in one depending Type of engine done most appropriately. In itself, the suction power of the suction head should always be so high be that the amount of oil delivered by the oil pump can be managed. This can be optimally combined on the engine test bench be coordinated.
