Abstract: An internal combustion engine for a motor vehicle drive includes a housing having a cylinder head water jacket, an exhaust water jacket and a combustion chamber water jacket. A valve is operable for adjusting a flow through a multi-channel coolant inlet. In particular, the valve provides continuous adjustment of a cross section, through which a fluid can flow of a multi-channel exhaust coolant outlet for admitting a flow to the exhaust water jacket and cross-section, through which a fluid can flow of a multi-channel combustion chamber coolant outlet for admitting a flow to the combustion chamber water jacket.

Abstract: A cylinder head for an internal combustion engine is provided which include a valve spring boss having a central opening for accommodating a valve and having a contact area for retaining said valve. The contact area has a first portion and a second portion. The first portion being ring-shaped and delimited by the opening, and the second portion being radially protruding from the first portion.

Abstract: A cylinder head is provided with liquid cooling system and a method for cooling the cylinder head. The cylinder head includes, but is not limited to a liquid jacket in which a coolant flows along a main flow pathway from a coolant inlet to a coolant outlet. The liquid jacket is interrupted between the coolant inlet and coolant outlet by portals to cylinders of an internal combustion engine. A second portal is arranged in a flow shadow of a first portal. The cylinder head in the liquid jacket exhibits a flow guide wall with a constriction of the flow cross section, and a baffle plate, which is arranged in the direction of the main flow pathway, downstream from the flow guide wall. The baffle plate is designed to divert a coolant flow branch in a direction of flow transverse to the main flow pathway, toward the second portal.

Abstract: A spark plug comprises a spark plug body, which carries two electrodes bordering a spark gap at one end, and exhibits a nut with external thread that can rotate around the spark plug body. A cylinder head exhibits a rotational coding complementary to the rotational coding of the spark plug body.

Abstract: An internal combustion engine is provided that includes, but is not limited to a securing device for installing a rocker arm on a cylinder head of the internal combustion engine, the securing element situated on the cylinder head and securing element securing the rocker arm during the installation of the rocker arm against slipping of the rocker arm off of a play adjuster and/or a valve shaft of a gas compensation valve.

Abstract: A motor vehicle and an oil supply device for a chain drive of a combustion engine for the motor vehicle includes, but is not limited to an oil collection device for collecting leakage oil of a component in the combustion engine and a feed line connected to the oil collection device, via which the leakage oil collected in the oil collection device can be fed to the chain drive.

Abstract: A vertical axis dispersion turbine is of the type which has a stator consisting of a stator tube with a cylindrical guide ring of larger diameter than the tube defining an annular inlet, an axial rotor shaft freely rotatable in the stator tube and having several blades in the guide ring to draw a medium to be mixed and dispersed downwardly through the annular inlet, and dispersion means through which the medium flows. The dispersion means consists of a dispersion element mounted on the guide ring in a plane transverse to the rotor shaft, either immediately above or below the rotor blades, or two dispersion elements above and below the rotor blades. The dispersion elements are axially adjustable, and may consist optionally of radial arms, or a grid with axial openings or a perforated plate with axial passages. The guide ring is slidably adjustable on the stator tube.
