  • Patent number: 4325339
    Abstract: A carbureting type fuel metering apparatus has an induction passage into which fuel is fed by several fuel metering systems among which are a main fuel metering system and an idle fuel metering system, as generally known in the art; engine exhaust gas analyzing means sensitive to selected constituents of such exhaust gas creates feedback signal means which through associated transducer means become effective for controllably modulating the metering characteristics of the main fuel metering system and the idle fuel metering system.
    Type: Grant
    Filed: November 30, 1978
    Date of Patent: April 20, 1982
    Assignee: Colt Industries Operating Corp
    Inventors: Kenneth C. Bier, Robert J. Miller

  • Patent number: 4169439
    Abstract: A carbureting type fuel metering apparatus has an induction passage into which fuel is fed by several fuel metering systems among which are a main fuel metering system and an idle-fuel metering system, as generally known in the art; electrical circuit means responsive to signals produced by associated engine exhaust gas analyzing means sensitive to selected constituents of such exhaust gas and also responsive to other selected indicia of vehicle and/or engine operating conditions, creates feedback signal means which through associated transducer means become effective for controllably modulating the metering characteristics of the main fuel metering system and the idle fuel metering system.

  • Patent number: 3968189
    Abstract: In a carburetor having an induction passage, a variable venturi in the induction passage, a fuel bowl and means for metering fuel flow from the fuel bowl to the induction passage, the method of compensating for changes in barometric pressure due to either atmospheric or altitude changes is disclosed as applying a vacuum or reduced pressure to the interior of the fuel bowl thereby reducing the fuel pressure which would otherwise exist, and causing a corresponding reduction in the mass rate of fuel flow in relation to the volume rate of air flow generally in accordance with a reduction in ambient pressure.

    Inventor: Kenneth C. Bier
  • Patent number: 3937768
    Abstract: A carburetor for use in combination with an internal combustion engine has a body with an induction passage formed therethrough; a variable venturi within the induction passage is effective for variably determining the opening of a venturi throat defined thereby; and a throttle valve situated in the induction passage downstream of the variable venturi is operatively connected to the variable venturi for positioning the variable venturi generally in accordance with the position of the throttle valve.
