- the valves can be arranged directly in the cylinder cover.
- the valves are actuated by an external control, which has levers and bumpers. Springs are used to close the valves.
- a control or camshaft carries the intake and exhaust cams.
- the invention is based on the problem of developing an internal combustion engine in which the metabolic process is controlled in a simple manner and which no longer requires cam-operated mushroom valves for controlling the metabolic process.
- Genus according to the invention solved in that a ring rotor is rotatably mounted around the cylinder head and / or the cylinder block, in which an intake duct, which is arranged in the cylinder head and / or in the cylinder block, passes from the combustion chamber in the correct time with a channel for fuel and / or Air supply connects, and an outlet channel are arranged, which connects the passage in time with a channel for the emission of exhaust gases.
- This internal combustion engine eliminates valves, levers, bumpers on cams, camshafts and springs.
- the metabolic process is controlled by the ring rotor or ring body. There are therefore less complicated parts than in conventional internal combustion engines necessary to control the metabolic process.
- a particular advantage of the internal combustion engine described above can still be seen in the fact that the passage or the passage opening to the combustion chamber, which can be part of the combustion chamber, and the intake and exhaust channel for generating a low intake vacuum and a low exhaust back pressure are correspondingly large in cross section to let.
- the center line of the cylinder is inclined against the axis of rotation of the ring rotor, that the combustion chamber delimited by the cylinder head and the piston in its top dead center is asymmetrical to

- the respective ring rotor preferably has a toothing on its outer circumferential surface, such as a ring gear, which is connected by means of a gear mechanism to a crankshaft driven by at least one piston via the piston rod.
- the respective ring rotor is positively and therefore inevitably controlled via the rotational positions of the crankshaft in such a way that the passage is opposite the respective outlet duct or intake duct with the correct cross-section.

- the ends of the cylinders (194), (196) facing a cylinder head (210) are arranged next to one another in the longitudinal direction of the crankshafts (204), (202).
- a ring rotor (212) is rotatably mounted on the cylinder head (210) about an axis of rotation (214).
- the type of arrangement of the cylinders (194), (196) shown in FIG. 8 results in a ring rotor (212) with a smaller diameter than the ring rotor (174) shown in FIG. 7.
- the cylinders (196), (194) are connected to an intake duct (216) in the ejection phase of the respective piston and an outlet duct (218) in the ejection phase of the respective piston or cylinder by means of passages which are not described in any more detail.
- the intake duct (216) and the exhaust duct (218) connect the cylinders to ducts of the cylinder head or the cylinder block, which are not specified in more detail, for the intake of the fuel / air mixture or for the discharge of the combustion gases.
- a four-stroke internal combustion engine with two cylinders (220), (222) is shown, which in a e.g. engine block (224) composed of two parts are arranged.
- the pistons (228), (230) of the cylinders (220), (222) are connected to a common crankshaft (226) via crank rods, which are not specified in any more detail.
- the center lines (232), (234) of the two cylinders (220), (222) - projected into a plane running perpendicular to the axis of rotation of the crankshaft (226) - form an obtuse angle with one another, which is not described in more detail.
- the cylinders (230), (228) work in opposite directions to each other.
- Each cylinder head (236), (238) closes off the cylinders (220), (222) at one end.
- ring rotors (240), (242) are rotatably mounted, which are rotatable about axes (244), (246), are inclined against the respective center lines (232), (234), ie the axes (244), (246) and the center lines (232), (234) intersect acute angles.
- Each cylinder (220), (222) contains, at its end facing the cylinder head (236), (238), a passage (248), (250) which goes into the unspecified cylinder wall of the cylinder head (236) or (238) opens out around which the respective ring rotor (240), (242) is rotatably mounted.
- the ring rotors (240), (242) are each provided with a suction and an outlet channel in the manner described above in connection with the ring rotor (134), the passages (248), (250) with in the suction or exhaust phase Connect ring channels which are arranged in the cylinder heads (236), (238) or the cylinder block (224) for the fuel / air mixture supply or the exhaust gas discharge. It is also pointed out that the teaching according to the invention can also be implemented with injection and turbo engines.
