Abstract

Aspects of the present invention relate to a control system and method for a hydrogen fuelled internal combustion engine (100) of a vehicle. The control system (120) is configured to receive an indication of a pressure of hydrogen in a hydrogen storage system (210). In dependence on the pressure being above a threshold pressure value, the control system (120) operates the internal combustion engine (100) in a first mode by controlling a fuel injector (115) to inject hydrogen gas from the storage system into a cylinder (104) of the internal combustion engine within a first fuel injection window (330). In dependence on the pressure being below the threshold pressure value, the control system operates the internal combustion engine in a second mode by controlling the fuel injector to inject the hydrogen gas into the cylinder within a second fuel injection window (340). The first fuel injection window (330) extends later into the compression stroke than the second fuel injection window (340).
