摘要： A fuel system comprises a first reservoir for a first fuel in liquid phase that has a first vapor pressure, and a second reservoir for a second fuel in liquid phase that has a second vapor pressure. The second vapor pressure is higher than the first vapor pressure. The fuel system further includes a mixing device for mixing the first fuel in liquid phase with the second fuel in liquid phase, and an injector which is hydraulically connected to the mixing device and is configured so that as, or immediately after, the mixture passes through an outlet opening of the injector, the second fuel changes from the liquid phase to a gaseous phase.
