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.
