Abstract
Methods and systems are provided for increasing an amount of oxygen in a pre-chamber of a cylinder prior to combustion. In one example, a method may include purging residual gases from a pre-chamber to a cylinder via a pre-chamber air injection, and reducing a flow of the oxygen from the pre-chamber to the cylinder via a cylinder fuel injection directed toward an orifice fluidically connecting the pre-chamber with the cylinder. In this way, a composition of pre-chamber gases may be adjusted during a combustion cycle of a cylinder.
