Abstract: A prechamber device includes an enclosure body and a cap forming an enclosed volume. The enclosure body has an orifice at one end. A precombustion chamber is defined within the enclosed volume and is in fluid communication with the orifice. A valve plug is movable along an axial axis of the enclosure body to adjust a valve opening at the orifice to a range of positions from a fully open position to a closed position. An actuator is coupled to the cap and the valve plug and is controllable to displace the valve plug along the axial axis of the enclosure body. The prechamber device is operable to generate turbulent jets that are directed into a main combustion chamber of an engine cylinder through the valve opening. During an engine cycle, the valve opening is controlled between the range of positions based on detected engine speed and engine load.

Abstract: An apparatus for igniting a fuel mixture provides an ignition system for generating a high-voltage ignition voltage, a circuit device comprising a circuit for superimposing a high-frequency signal on to the high-voltage ignition voltage, a spark plug in an engine block, and a transmission element having a high-voltage conductor which is guided in an insulation element. The high-voltage conductor is used for transmitting the ignition voltage, onto which the high-frequency signal has been superimposed, to the spark plug. Further provided is an electrically conducting shielding element which surrounds the high-voltage conductor in an electromagnetically shielding manner at least along one portion of the longitudinal axis of the high-voltage conductor. The shielding element is connected in an electrically conducting manner to a ground potential of the circuit device and establishes a connection between the ground potential of the circuit device and a ground electrode of the spark plug.
