Abstract
A multi-mode engine system comprising a first mode in which the engine is fuelled substantially entirely by a first fuel, and a second mode in which the engine is fuelled substantially entirely by a second fuel, or by a mixture of the first and second fuels, the engine comprising: a first engine control unit (ECU) for controlling the flow of the first fuel into the engine when the engine is operating in the first mode; and a second ECU operatively connected to the first ECU; wherein the first ECU comprises: a signal receiver for receiving the first input signals, and an output for emitting a first output signal; and the second ECU being adapted to modify the first output signal when the engine is running in the second mode to produce a first modified signal and a second calculated signal.
