<p>1512360 Atomizing liquid fuel FORD MOTOR CO Ltd 10 March 1977 [5 April 1976] 10062/77 Heading F1H A two-stage carburettor has the secondary barrel 64 concentric with and surrounding the primary barrel 28 which is extended by a slidable tube 61 so that it terminates close to an exhaust gas heated portion 16 of the intake manifold wall. Fuel supplied to Venturii 36, 38 is vapourized on the hot spot before being drawn through annular gap 84. Tube 61 is mechanically linked to operator controlled throttle valve 56 so that gap 84 becomes larger as the throttle is opened. Secondary air flow is controlled by vacuum or mechanically operated valve 80. Alternatively, Fig.2 (not shown) fuel is supplied to the primary barrel through a fixed central plug (224) in the primary barrel which co-operates with a Venturishaped portion of the primary barrel which is integral with and moves with the slidable tube to control air flow.</p> |
