Abstract: The invention relates to rapid multiple ignition, in which the maximum breakdown voltage for the spark breakdown is available a number of times during an ignition time window. The ignition system operates with a DC converter with which the voltage of the on-board vehicle electrical system is increased, and with rod-type ignition transformers whose minimized ignition coils permit rapid recharging. The ignition electronics operate with a power output stage which charges the rod-type ignition transformer by switching a power switch in the ground path of the primary winding. The output stage power switch is actuated by a time control arrangement which clocks the power switch for charging the rod-type ignition transformer and connects the primary side of the ignition transformer to ground for a prespecified time period in order to achieve the spark breakdown after charging of the ignition transformer.

Abstract: The invention relates to an ignition system for a 14 V or 42 V on-board power system voltage which is connected to the ignition transformer directly via the semiconductor power output stage without an intermediate power unit. After an input signal from a superordinate engine control device, the semiconductor power output stage is switched on by an ignition control device. As a result, a current is built up at the primary side of the ignition transformer. After the predefined maximum current value is reached for the first time, the primary side of the ignition transformer is switched off for a predefined time period. In this time period, a maximum voltage for the spark breakdown is built up at the electrodes of the spark plug according to the principle of self induction. After the spark discharge, the primary side of the ignition transformer is timed and current-limited until the end of the ignition process which is predefined by the superordinate engine control device.

Abstract: A method and a system for the ignition of an internal combustion engine in which a high voltage is applied to the electrodes (8.1, 8.2) of a spark plug (8). The high voltage produces a voltage disruptive discharge on the electrodes (8.1, 8.2) of the spark plug (8) and the combustion phase is maintained over the voltage disruptive discharge. The electric power for triggering a disruptive discharge at the electrodes (8.1, 8.2) of a spark plug is supplied according to a self-induction method, while the combustion phase is maintained by the voltage resonant conversion.

Abstract: The rod ignition transformer including an integrated low-voltage connector to the on-board network supply, and an integrated high-voltage connector to the spark plug, both accommodated in a housing. In the housing, the primary coil and the secondary coil surround a central core comprising a ferromagnetic powder composite material. A magnetic feedback member is formed from a highly-permeable magnetic material having low eddy current losses. The magnetic feedback member preferably is formed from ferrite.

Abstract: An ignition system supplies high-voltage to spark plugs via field emitters. An ignition control device produces the ignition cycle for the ignition system and controls the ignition process of the ignition system. The field emitters couple the ignition control device to the spark plugs. The field emitters switch and regulate the high-voltage for the spark plugs.
