Disclosed herein is a closed loop fuel control system for a hydrogen fuelled engine embodying a hydrogen sensor in the exhaust manifold to provide a feedback signal indicative of the quantity of unburned hydrogen in the engine\s exhaust. The system electronically controls or trims the fuel delivery to the engine in response to signals indicative of the engine\s operating parameters and the signal generated by the hydrogen sensor to maintain the concentration of hydrogen in the exhaust at a predetermined level.

A closed loop fuel control system for a hydrogen fuelled engine, wherein said engine includes a source of hydrogen fuel and an engine control, the position of which is indicative of a commanded engine torque, comprising: means for generating a hydrogen feedback signal having a value indicative of the concentration of unburned hydrogen in the residue of the engine\s combustion process emitted as an exhaust gas; and means for controlling the quantity of hydrogen and an oxidizing agent delivered to the engine in response to the position of said engine control and said hydrogen feedback signal to cause the engine to generate the commanded torque with the exhaust gas having a predetermined quantity of unburned hydrogen.
