Fuel feed control means for an internal combustion engine adapts the injected fuel quantity in dependence on fuel composition (eg. methanol content). Both the injection duration and the fuel pressure are variable; injection duration being varied, for example, in dependence on engine operating characteristics and fuel pressure in dependence on the fuel composition Fuel composition may be measured by means of a sensor 22 in the fuel tank 10 or by means of an exhaust gas sensor. Pressure variation may be continuously variable by a single pressure regulator 14 or stepwise by means of a plurality of selectable regulators. <IMAGE> |
