Abstract: A first voltage signal and a second voltage signal each with positive and negative half waves are generated for rotation direction detection during the operation of an ignition device for an internal combustion engine by a rotating magnet wheel in at least two coil arrangements, which are arranged on adjacent core legs of an iron core, whereby the rotation direction of the magnet wheel is determined from a time offset or angular offset of at least one half wave of the first voltage signal relative to a half wave of the second voltage signal.

Abstract: An ignition procedure for internal combustion engines using multiple coils of a generator coupled to and turning synchronously with the engine. A magnetic field flows through the coils and generates a sequence of alternating current half waves induced in the coils. The half waves are used for: (1) charging an energy storage element that is discharged by an ignition switch via the primary coil winding for triggering an ignition spark; (2) processing via a control device for activating the ignition switch at an ignition time in dependence on the processed alternating current half waves and/or on the state of the internal combustion engine; and (3) the power supply for the control device (U8), and an operating mode for switching combustion off for the engine, whereby by means of the control device, the ignition switch is guided over less than the time span that is needed for a complete revolution of the magnetic generator.

Abstract: A two-stroke engine has a cylinder with a combustion chamber delimited by a reciprocating piston, wherein the piston drives in rotation a crankshaft, and wherein a spark plug projects into the combustion chamber and ignites a fuel/air mixture. The two-stroke engine further has devices for supplying fuel and combustion air to the combustion chamber and a control unit that determines the ignition timing based on an ignition map. The ignition map indicates the ignition timing as a function of the engine speed for at least one first and one second operating states and for at least one first and one second engine speed ranges. The engine is controlled in that for an engine cycle the ignition timing is set in the second operating state at least within the first engine speed range based on the engine speed and on the number of engine cycles since the last combustion.

Abstract: Electrical ignition procedure for internal combustion engines, using an arrangement of multiple coils and of a magnetic generator that is coupled with the machine and turns synchronous to the machine, whose magnetic field partially flows through the coils and thereby generates a sequence of magnetic flux changes for each revolution, whereby a sequence of corresponding alternating current half waves is induced in the coils, that are used for: charging an energy storage element that is discharged by activated an ignition switch via the primary coil winding of an ignition transmitter for triggering an ignition spark for the combustion engine scanning, acquiring, processing and/or assessing via a microelectronic and/or programmable control device, that is used for activating the ignition switch at an ignition time in dependence on the acquired and assessed alternating current half waves and/or on the state of the internal combustion engine, such as its rotational setting or speed, and for formation of the powe
