Abstract: A cylinder block for an internal combustion engine which includes dry liners each having a flange, and in which cooling slots are provided between two cylinders that start from the separating plane facing the cylinder head and are in communication with the cooling water circulation; the wall thickness of the cylinder block between two cylinders is thereby so dimensioned that the circumferential surfaces of the flanges at the liners are either tangential with a cooling slot; or with larger flanges in the radial direction, the flanges abut at one another above the cooling slot.

Abstract: A multi-cylinder internal combustion engine with a valve shutoff. A mechanical device in which is integrated a valve clearance compensation arrangement, is interposed between an end of the valve stem and the valve actuating arrangement. A mechanical device includes a cup tappet and serves respectively arbitarily in one case as a rigid connecting member between the end of the valve stem and the valve actuating arrangement and, in the other case, during a closed position of the valve, eliminates the connection between the end of the valve stem and the valve actuating arrangement.

Abstract: A switching means for effecting a shutoff of valves of a multi-cylinder internal combustion engine wherein a servomechanism is provided which, upon a shutting off of the valves, acts upon an interposed energy storage arrangement in such a way that a spring-loaded leading mass of the energy storage arrangement, after a predetermined lead path, entrains an element connected with adjusting members for shutting off the valves.

Abstract: A filter housing for accommodating at least one filter insert to filter lubricating oil, which is provided in the installed position with a geodetically upper assembly opening for inserting and interchanging the filter insert and with a geodetically lower base; the housing interior space is connected by way of two separate housing channels extending in the base, with one housing connection each for the inlet of dirty oil and for the outlet of clean oil; the housing interior space can also be connected with a housing connection separate from the housing connection for the inlet of dirty oil by way of a drainage connection adapted to be closed off by means of a closure device which can be opened at will.

Abstract: An exhaust gas channel system which is arranged in the cylinder head of an internal combustion engine and in the housing of an exhaust gas turbo charger flangedly connected to an exhaust flange disposed along the side of the cylinder head; the exhaust apertures of each cylinder are thereby each arranged in that half portion of the respective cylinder which is disposed nearest the cross center plane of the cylinder head while the exhaust gas channels are constituted exclusively by cast-in walls of the cylinder head, on the one hand, and of the exhaust gas turbo-charger, on the other; the latter is threadably connected to the exhaust flange of the cylinder head by means of a complementary counter-flange matched to the exhaust flange of the cylinder head.
