PREDICTIVE MODEL-BASED SPARK CONTROL

In certain embodiments, remarkable improvements in H2-ICE performance may be achieved with the combination of Active Scavenge Prechamber technology and Predictive Model-Based Spark Control to overcome the drawbacks of known combustion technologies. In certain embodiments, advanced combustion modeling and simulations of the ignition process including the spark event, the arc-travel and stretching, and resulting flame propagation may be used to predict the relationship between the spark energy/power, the flow within the electrode gap, and the flame development (SOC) for different engines, different spark plugs and at various conditions. This information may be used to adjust the spark energy/power characteristic during the same cycle spark event, to minimize the SOC variations and to significantly reduce the propensity to combustion anomalies, such as backfire, knock and preignition, that prevent achieving high engine power densities and efficiencies.
