Abstract
A system for controlling enriched prechamber stoichiometry includes a prechamber ignition device, and an ignition control system that includes a sensor structured to measure an amount of at least one of CO2 or O2 in a prechamber, an engine timing sensor, a fuel quality sensor, and an electronic control unit. The electronic control unit is structured to receive signals from each of the sensors and determine an air-fuel ratio of the prechamber for comparison with a target air-fuel ratio, and produce a fuel delivery signal based on the comparison.
