MULTI-FUEL ENGINE CONTROL WITH FUEL COMPOSITION RESPONSIVE FUEL VISCOSITY CORRECTION Abstract of the Disclosure A vehicle engine fuel control adapted for multi-fuel operation uses a fuel injection system in which fuel in a liquid mixture of first and second combustible fuels is injected in pulses of controlled duration at a predetermined pressure to achieve a predetermined air/fuel ratio. The first and second combustible fuels have different viscosities, so that the viscosity of the mixture changes with its composition as well as fuel temperature. The duration of the portion of the pulse duration in which fuel flows is varied in response to fuel composition and fuel temperature so as to compensate for the variation in viscosity of the fuel mixture and thus deliver the required amount of fuel with each pulse.
