Abstract

Internal combustion engines based on conventional operating principles have to convert a longitudinal movement into a rotating movement. For this they require both energy and a greater number of components. With known rotary engines, such as Wankel engines, optimal compression of the fuel-air mixture is not possible and sealing between the rotary piston and cylinder wall problematic. Owing to insufficient compression self-ignition systems are not possible either, as is also the case with other types of rotary engines or rotary piston systems. In contrast, in a rotary reciprocating internal combustion engine the pistons in the rotor operate in accordance with the camshaft principle, the rotor in the endless rotary cylinder rotating together with the pistons working in it. Power transmission to an operating shaft is from gear wheel to ring gear.

Description

The invention describes an internal combustion engine in which a piston rotates circularly in a circular endless cylinder, which is simultaneously designed as a cylinder, in which another piston sucks in fuel at a right angle to the rotating piston, compresses it and works when it is ignited ( FIGS. 1, 2 and 3 ).

The be in the rotary piston engine or as a rotary piston engine Known technology uses a triangular body as the center of attention own axis in an asymmetrical closed oval cylinder working piston, the edges of the triangular piston on the Wall of the asymmetrical oval compression and combustion chambers form. The edges of the rotary piston seal unsatisfactorily from, so that fuel and energy losses arise.  

The compression of the fuel-air mixture is u. a. thereby negative influenced. Optimal compression like the piston engine is not satisfactory possible. In practice there has been higher gasoline consumption and susceptibility to repairs are shown. With the conventional piston engine combustion engine is indeed the gasoline consumption by optimization, especially the fuel supply units, in recent times have been significantly improved, but due to the loss of energy the masses of weight due to centrifugal forces that act on the pistons as well their abrupt reversal in the cylinder because of the transformation of the longitudinal be movements in rotary movements, costs energy and limits the possibilities speed of further utilization of the fuel by e.g. B. even higher rotation numbers. Furthermore, the conventional four-stroke internal combustion engine with complex techniques regarding the valve controls and the Valves themselves with the valve spring pressure to be overcome. The two-stroke engine has a higher fuel consumption and Pollutant emissions, and the disadvantage of converting Longitudinal movements in rotary movements is also due to abrupt reversal Movement of the pistons with force and material wear due to connecting rods given poles.

The invention specified in the claims lies Underlying the problem, to avoid as far as possible, longitudinal movement must be converted into rotary movements, but without being seen to bring about a compression of the fuel-air mixture, a technically improved and at the same time simpler and more fuel to achieve saving technology that reduces pollutant emissions.

This problem is addressed by those listed in the claims Features solved by arranging the cylinders and pistons one in the conversion of the energy in the fuel, by Rotational movements are implemented in force. By this arrangement there is also an optimal compression of the fuel air mix because a piston in a cylinder that at the same time performs the function of a working piston, perpendicular to it, the loading process and the compression and exhaust process / exhaust executes. Here are all the parts that are in the circular endless cylinders are located together in rotary motion.

The so-called bicylinder, which is also a piston and in the cylindrical recess of which another piston works at right angles to this bicylinder ( FIG. 5), rotates in the endless cylinder.

Here, caused by the eccentric piston drive roller ( FIG. 1, indicator 8 , FIG. 6, indicator 8 ), the piston is moved back and forth or up and down.

The bizylinders are designed twice for an endless cylinder, but can also be designed twice twice per endless cylinder or with only one bizylinder. In this case there is a swing weight opposite ( Fig. 7).

There are bars as follows:

• 1. suction; The piston in the bicylinder moves down in the intake area and opens the fuel inlet opening with its upper edge. The opposite bicylinder in the endless cylinder moves upwards to eject in the exhaust area after the ignition has taken place in the ignition area. ( Fig. 1, indicator 15 , 17 ).
• 2. expelling; Compacting; The piston in the now running bicylinder compresses the fuel-air mixture, while the piston of the opposite bicylinder has reached and exhausted the exhaust area ( Fig. 2, indicator 30 A and 18 ).
• 3. work; The piston at the first intake in the bicylinder has reached the ignition area with the compressed mixture and is moving again in the downward direction ( FIG. 3, indicator 16 ).

The control and setting for ignition timing, compression and ejection takes place by aligning the toothing of the gear wheels with the gear rings for driving the eccentric piston roller drive shafts ( Fig. 7, indicator 11 and Fig. 4, Fig. 4A, Ind. 12 ).

The pistons in the bicylinder are used for ignition and fuel injection set in downward motion. That is why he is invention equipped with a device which be acts to force the piston against the eccentric piston drive rollers to follow the downward movement.

The central piston unrolling rollers are mounted in a housing in the piston cavity ( Fig. 9, indicator 27 and 21 ).

The shaft ( Fig. 9, Ind. 22 ) is located as an axis between the central piston rolling rollers. In the eccentric piston drive rollers there is a double roller track ( Fig. 8 and 9, indicator 25 ).

A shaft leads from one roller track to the other opposite ( FIG. 9, indicator 24 A). The rollers are supported at each end of the roller track shaft. The roller shaft is connected to the shaft of the central piston rolling rollers by a rigid push rod ( FIG. 9, indicator 23 ).

The roller tracks form internal folds on the rolling surface of the eccentric piston unrolling rollers, in which the rollers ( FIG. 6, Ind. 24 ) are located at the ends of the roller track shaft ( FIGS. 8 and 9, Ind. 25 ).

When the central piston roller drive shaft ( Fig. 4 and 6, Ind. 8 ) is rotated, the eccentric piston drive roller is caused to pull the piston by the rollers located in the fold (roller rails), the central piston roller unrolling on the running surfaces of the eccentric piston drive roller ( Fig. 8, Ind. 26 ).

As balancing weights against unbalance there are two eccentric balancing flywheels on the central piston roller drive shaft ( Fig. 4, Ind. 10 ).

With the invention, the advantages of the possibility of operation an internal combustion engine with higher speeds and thus higher Power development while saving fuel and pollutants reduction achieved. This is due to the fact that it is no longer applicable the conversion of back and forth movements into rotary movements and at the same time optimal compression of the fuel-air mixture as well as the omission of connecting rods, valve springs, in the case of the patent Claim 1 Elimination of the valves and their control directions, at.

Another advantage is achieved by keeping the motor free of complicated and failure-prone techniques to perform optimally brings. This becomes a huge advantage of business economics and profitability in terms of acquisition costs.

The further embodiment of the invention with a compressor or Diesel drive with the well-known high pressure system "Common-Rail- Technology ", the invention can still perform optimally to lend. In connection with the use of hydrogen as a drive fuel for internal combustion engines, this invention arrives very opposed to hydrogen. This applies in particular the application of those in DE 195 04 142 A1, 1995 and 26 17 361, 1976 described invention about simple manufacture and application of Hydrogen in internal combustion engines.  

Another embodiment of the invention is shown in the drawing in FIG. 10. It is the possibility of various arrangement positions (e.g. lying) of the invention in mobile or stationary use. Furthermore, the drawing shows one of the various possibilities of arranging the oil pump ( Fig. 10, Ind. 34 ), lubricating oil distribution ( Fig. 10, Ind. 34 ) and oil pan ( Fig. 10, Ind. 33 ).

When used as an aircraft engine, the oil distribution or the Lubrication of the engine in general like that of radial engines can be used as in any other use of the invention.

The invention can also be designed with several spark plugs as well Ejection / exhaust ports per circular endless cylinder. This possibility arises independently of the intended one other charging ignition and ejection times and positions to be regulated in a circular endless cylinder, independently adjustable for everyone Bicylinder via its gear drive for the eccentric pistons unrolling roller.
