Abstract: In an ignition electrode arrangement at a cylinder in an internal combustion engine, for example an Otto-engine, a first electrode and a second electrode co-operate with each other, the first electrode being arranged on an ignition device secured to a cylinder head. Both electrodes are movable in order to enable a change in the size of the spark gap and/or the position of the spark gap. The electrodes are each manipulated by an operating device that is controlled by a control unit included in the ignition system of the engine.

Abstract: In an ignition electrode arrangement for a cylinder in an internal combustion engine, for example an Otto engine, a cylinder head (3) bears a first electrode (7) and a second electrode (8) which interact with one another. At least the first electrode (7) is arranged on an ignition means (6) fastened in the cylinder head. According to the invention, the second electrode (8) is movable relative to the cylinder head (3) and the first electrode (7) in order to make it possible to change the spark gap. The second electrode (8) can be mounted on the cylinder head (3) itself or on the ignition device (6). The size of the spark gap is controlled during operation by the ignition system of the engine.

Abstract: A new two-cycle internal combustion piston engine in which combustion originates within the cylinder head between a positive displacement gear type air compressor and an intake valve sealing the cylinder from the compressor outlet. At approximately TDC fuel is injected into the cylinder head combustion passages initiating combustion and the camshaft opens the intake valve. The opening intake valve allows the burning fuel mixture to flow into the cylinder forcing the piston towards BDC. The compressor is crankshaft driven and continues to force air into the cylinder head combustion passages while the engine runs which causes the fuel to burn more rapidly increasing engine torque. Exhaust valves located in the cylinder head are opened at BDC by the cam as the intake valve closes.

Both electrodes (7, 8) are movable in order to enable a change in the size of the spark gap. The electrodes are each manipulated by means of an operating device (10, 14) that is controlled by a control unit (13) included in the ignition system of the engine.
