摘要： A method for operating an internal combustion engine with compression ignition or with spark ignition as a function of an operating point. A specific residual exhaust-gas quantity in the combustion space is set for compression ignition. The internal combustion engine is operated as a function of the operating point by an outlet cam, by which a first outlet opening phase and a second outlet opening phase take place. The second outlet opening phase commences during an inlet opening phase. At a first operating point in a compression-ignition mode, a residual exhaust-gas quantity in a combustion space is dimensioned as a function of a valve interference set between the inlet and the outlet valve during a charge exchange. At a second operating point in the compression-ignition mode the residual exhaust-gas quantity in the combustion space is dimensioned as a function of a duration of the second outlet opening phase.

摘要： The invention relates to an internal combustion engine (1), in particular in a motor vehicle, comprising at least one cylinder (3) that defines a combustion chamber (4) and in which a piston (5) can be adjusted with regard to stroke. Each cylinder (3) comprises at least one intake opening (6) for a fresh mixture. Each intake opening (6) is associated with an intake valve (7) that works together with an associated valve seat (8) in order to control the intake opening (6). At least one such intake opening (6) is provided with a guide mask (9) that laterally encloses the respective valve seat (8) on a side that is opposite the respective combustion chamber (4) along a delimited circumferential section. Each intake opening (6) is associated with an intake canal (10). In order to improve the operation of the internal combustion engine (1), at least one intake canal (10) leading to a masked intake opening (6) is associated with an additional valve (11) for controlling the intake canal (10).

摘要： An arrangement for the actuation of a gas-exchange disk valve longitudinally guided in the cylinder head of a reciprocating piston which is opened and closed against spring force by two alternately periodically energized electromagnets. An armature coaxial to the disk valve together with an armature disk secured at the same is thereby moved to and fro and stresses a cylindrical torsion rod spring clamped-in at the cylinder head by way of a valve lever pivotally connected at the armature. For compensating manufacturing tolerances and thermal expansion, a magnetizable entrainment disk is arranged in the armature disk with axial play which is threadably connected with the stem end of the disk valve and effects the tight closing thereof.
