Abstract
A method and apparatus for supplying a gaseous fuel to a combustion engine is described. A required fuel flow is calculated, an actual fuel flow is measured, and a fuel flow control signal is adapted if a difference between the required and actual fuel flow is detected. The fuel flow may be measured using a differential pressure measurement. The fuel flow control signal and associated actual fuel flow may be stored in a continuously updated memory. The apparatus includes a pulse width modulation valve arranged in a fuel line, a fuel flow measurement assembly arranged downstream of the valve, and a device for generating a control signal for the valve. The control signal generating device is supplied with feedback from the flow measurement assembly and includes a continuously updated table for storing control signals and associated fuel flows.
