ABSTRACT:
A combustion engine is shown with a fuel metering device having a fuel reservoir or fuel bowl with such, in turn, having a float-controlled fuel inlet valve; a fuel supply conduit leading from a vehicular fuel tank to the inlet of the fuel bowl has a normally open solenoid valve and a flow meter situated in series therewith; a control device receiving signals indicative of engine speed and rate of fuel flow to the fuel bowl is effective to cause the solenoid valve to close and terminate further fuel flow whenever the numerical ratio of the rate of fuel flow divided by the engine speed exceeds a preselected magnitude of such a ratio or index.
