Abstract

A control apparatus for an internal combustion engine fuel injection system has a cam rotatable between a normal position and a cold-starting position, a cam follower movable in response to engine intake manifold pressure to vary the position of a metering valve control stop in accordance with said pressure and with the cam position, and a latch pivotally mounted on the cam and biased so as to limit movement of said control stop, and hence fuel flow, when the engine is started with the cam in its normal position. The latch is moved by the cam follower to an inoperative position when the engine is running. A damping arrangement slows movement of the latch in response to its biasing means.
