Abstract:
1. A fuel system for injection of a fuel mixture in a combustion engine, the fuel system comprises: an inlet circuit configured and operable to lead fuel to the engine, the inlet circuit comprises a space configured and operable to receive a first fuel from a first fuel source and a second fuel from a second fuel source, the inlet circuit includes a feed pump configured and operable to transfer fuel into the inlet circuit, the inlet circuit space is located upstream of the feed pump in the inlet circuit with respect to an intended direction of flow in the inlet circuit; the feed pump is configured and operable and connected to draw the first fuel from the first fuel source and the second fuel from the second fuel source to feed them to the inlet circuit space; a high-pressure pump located to receive and pressurize fuel from the feed pump; an accumulator tank configured and operable to receive and store fuel from the high-pressure pump; at least one injection unit configured and operable to receive fuel from the accumulator tank and to inject the fuel into a combustion space of the engine; a mixing device configured and operable to apply a mixing movement to the first fuel and the second fuel for producing a substantially uniform fuel mixture for the injection unit to inject into the engine's combustion space; and a return circuit configured and operable for receiving unburnt fuel from the engine and leading the unburnt fuel back to the space in the inlet circuit.
