AI Technical Summary
Existing methods for operating spark-ignition internal combustion engines with hydrogen fuel fail to adequately determine the fuel quantity, leading to combustion anomalies such as knocking, as they are based on air flow regulation typical for gasoline engines, which does not account for hydrogen's unique combustion behavior.
A method for determining the fuel quantity in hydrogen-powered engines independently of a fixed lambda setpoint, considering air quantity, exhaust gas recirculation, and inert agent supply to stabilize combustion and prevent anomalies, allowing flexibility in fuel control.
The method stabilizes combustion, prevents knocking, and maintains efficient operation by adjusting fuel quantity based on air, exhaust gas recirculation, and inert agent supply, ensuring a lean mixture and increased flexibility in engine performance.
