Abstract: An engine-generator arrangement comprising an internal combustion engine whose output shaft is connected to the drive shaft of the generator by way of an elastic coupling, wherein the engine casing of the internal combustion engine is connected elastically and preferably rubber-elastically to the generator casing of the generator.

Abstract: An arrangement for regulating a spark-ignition internal combustion engine, in particular a stationary boosted gas Otto-cycle engine, comprising a power regulating device acting on at least one power setting member, wherein an ignition time regulating device (8, 9, 10) adjusts the ignition time (ZZP) in dependence on the position of the power setting member (2).

Abstract: An ignition system is disclosed that is capable of configuring the development or pattern of the ignition spark in a freely pre-selectable manner. The system has an ignition coil that is supplied on the primary side by a high frequency source (HF Source) that is pulse width modulated. The pulse width is regulated based upon the measured actual value of the current on the secondary side of the ignition coil and upon a pre-selected reference value development of the current amplitude during an ignition spark.

Abstract: A spark ignition internal combustion engine (1), in particular an Otto-cycle gas engine, with at least one ignition device (14) per cylinder (2), wherein at least one piston (4) has a recess (8) in the piston head and wherein the recess (8) in plan view on to the piston head is of a substantially heart-shaped shape which differs at least in a region-wise manner from a circular shape, wherein the shape of the recess (8) in a plan view on to the piston head has precisely one axis of symmetry (10).

Abstract: Internal combustion engine (8), in particular a stationary gas engine, with a bypass (6) going around the super-charger (4), in which at least one detonation protector (11) is arranged.

Abstract: An internal combustion engine, in particular a stationary gas engine, comprising a compressor arranged in the induction tract, in particular an exhaust gas turbocharger, an electrically operable blow-off valve connected downstream of the compressor, and a pressure sensor for detecting the pressure actual value of the mixture in the region of the blow-off valve. In according with the invention there is provided a device (9) for detecting the engine power output (N), a device (10) for calculating a pressure reference value in dependence on the detected engine power output and a relationship previously stored in a memory between engine power output (N) and pressure reference value (Psoll), and a regulating device (11) for regulating the blow-off valve (7) until the pressure actual value (Pist) reaches the calculated pressure reference value (Psoll).

Abstract: A bearing arrangement for supporting a movable component, in particular the crankshaft, of an internal combustion engine, having at least one bearing for receiving the component and an oil feed line to each bearing, wherein a filter (5) is arranged in the oil feed line (7) directly upstream of the bearing (3).

Abstract: A valve drive for a valve of an internal combustion engine, wherein the valve is connected to a main piston which is arranged in a cylinder chamber and which for opening of the valve can be acted upon by pressure fluid flowing into the cylinder chamber, wherein there is provided a closing spring which urges the valve in the closing direction, and wherein there is provided a throttle by way of which a part of the pressure fluid flows out of the cylinder chamber in a throttled flow during the closing movement of the valve.

Abstract: Ignition coil for internal combustion engines with two or more transformer stages connected in a cascade arrangement one behind another.
