Abstract
Systems and methods are provided for a variable volume pre-chamber igniter, which may be coupled in an engine system. In one example, a system may include a pre-chamber igniter coupled to a cylinder of an engine, the pre-chamber igniter including a movable cap enclosing an internal volume of the pre-chamber igniter and separating the internal volume of the pre-chamber igniter from an internal volume of the cylinder. By adjusting a position of the cap, the internal volume of the pre-chamber igniter may be adjusted to provide reliable ignition to the cylinder across a wide range of operating conditions.
