Abstract
Methods and systems are provided for operating a cylinder of an engine including a pre-chamber ignition system. In one example, a method may include determining amounts of pre-chamber gases in the cylinder prior to combustion, and adjusting an amount of fuel injected into the cylinder based on the amounts of pre-chamber gases in the cylinder. In this way, cylinder fueling may be compensated for additional air and/or fuel from the pre-chamber gases, which may increase an accuracy of the cylinder fueling and increase cylinder efficiency.
Claims5
A system, comprising:
- an engine including a plurality of cylinders, each cylinder including a cylinder fuel injector and a pre-chamber of a pre-chamber ignition system;
- and
- a controller storing executable instructions in non-transitory memory that, when executed, cause the controller to:
- purge gases from the pre-chamber to the corresponding cylinder;
- and
- adjust a fuel injection amount of the cylinder fuel injector based on an amount and composition of the gases purged from the pre-chamber.
