Abstract: An internal combustion engine for a motor vehicle has at least one cylinder, a cylinder head, and a piston which is movably mounted in the cylinder and has a combustion chamber side which delimits a combustion chamber with the cylinder head and the cylinder. The cylinder head has a combustion chamber roof, in which at least two valve seats for at least one inlet valve and at least one outlet valve are provided. The combustion chamber roof has at least one arched cylinder head section which is arranged between the at least two valve seats and points away from the combustion chamber.

Abstract: A valve control of an internal combustion engine has a camshaft and a cam sleeve, which surrounds the camshaft and is fastened in an axially movable manner and has cams, which are associated with individual valves and extend in the radial direction. The cam sleeve can be moved in the axial direction in relation to the camshaft by an actuator during rotation. The cam sleeve has at least two axial segments, which can be moved in relation to each other in the axial direction by the actuator, which engages in the axial segments.

Abstract: A control shaft of a cam shaft adjustment unit has axially spaced adjustment cams, which are designed in a first axial section of the control shaft for a continuous operation of a cylinder and in a second axial section for a cylinder shut-off. The adjustment cams for the continuous operation of a cylinder have, over the entire circumference of the cam circle, a radial extension which is greater than a zero stroke extension and the adjustment cams for the cylinder shut-off have, around their circumference, a shut-off section of the cam circle with a radial extension which is less than or equal to the zero stroke extension. The control shaft has a stop that reduces the rotation in both circumferential directions and functions as the calibration point for an engine electronics system.

Abstract: In a variable valve control arrangement for an internal combustion engine including a cylinder head with a first camshaft having exhaust valve operating cams and intake valve opening cams, a second camshaft having intake valve closing cams, exhaust valve operating rocker arms pivotally supported on a rocker arm support shaft mounted on the cylinder head in a force transmitting relation with the exhaust cams of the first camshaft, intake operating rocker arms mounted on the same rocker arm support shaft, and engagement members disposed on the intake valve operating rocker arms and in contact with the intake cams of both camshafts for the transmission of the intake valve opening control movement of the first camshafts and the intake valve closing control movement of the second camshaft to the intake valves, the rocker arm support shaft is disposed below the first camshaft and is supported by bearing blocks disposed in the area between adjacent cylinders and by an additional support structure formed in the middl

Abstract: In an arrangement for a variable control of the valves of an internal combustion engine having a cylinder head with two intake valves and one exhaust valve for each cylinder, a first cam shaft having an exhaust cam for actuating the exhaust valve and two intake valve opening cams arranged at opposite sides of the exhaust cam for opening the intake valves and a second camshaft which is phase adjustable with respect to the first camshaft and includes two intake valve closing cams operating an intake valve operating lever structure, the intake valve operating lever structure is U-shaped and has legs pivotally supported on an operating lever support shaft on which also an exhaust cam operating lever is pivotally supported between the legs of the U-shaped intake valve operating lever structure.
