ABSTRACT:
A liquid and supplemental gas fuel supply system for an I.C. engine, and in particular a diesel cycle engine, includes a gas fuel control valve that meters supplemental gas fuel into the engine intake air stream in response to engine air flow using a direct air flow responsive member to control a gas valve through a lost motion connection. The position of the gas valve is moreover controllable by a separate throttle position responsive control system that moves the gas valve towards closed position as the throttle approaches the closed or idle position, and holds the gas valve closed until the throttle has moved away from the closed or idle position. The separate control motion of the gas valve is independent from the motion of the air flow responsive member and does not restrict or interfere with the movement of the latter.
