Abstract

1,205,142. Spray carburetters. FORD MOTOR CO. Ltd. Sept.18, 1968 [Sept.29, 1967], No.44265/68. Heading-F1B. The flow in the idling system is controlled by a valve 52, Fig. 1, operated by the suction downstream of the throttle valve. In Fig. 1, the valve 52, attached to a suction operated piston 48,controls the amount of bleed air flowing into the idling passage 24. As the throttle valve begins to open and the manifold suction decreases, valve 52 restricts the bleed orifice 28 to increase the suction in the idling passage and thereby increase the idling feed supply. The valve 52 may alternatively control the idle fuel orifice 32 or an orifice 35 in the idling passage 24.
