Abstract
1476548 Spray carburetters NISSAN MOTOR CO Ltd 4 March 1975 [19 March 1974] 8866/75 Heading F1H The flow of fuel to an idling and slow-running passage 15 and the flow of mixture in a passage 21 connected to the induction passages 11, 12 downstream of the throttle valves 13, 14 is controlled by respective valves 51 and 30 which prevent flow under over-running conditions of an associated engine. The valve 30 is operated by a diaphragm 27 subject in chamber 28 to a pressure substantially equal to that in the carburetter intake and in the chamber 29 to the suction downstream of the valve 14 via the open diaphragm-operated valve 35 when the valve 42 is closed. The valves 42 and 51 are solenoid valves energized to open and close respectively when a switch or switches in series with an ignition switch 70 are closed. The switches may be closed responsive to engine speed and throttle valve position (61 and 62), Fig. 3a (not shown), engine speed and intake manifold vacuum (64 and 65), Fig. 3c (not shown), or a single switch may be closed responsive to manifold vacuum (63), Fig. 3b (not shown). The switch or switches are closed when the engine is over-running above a predetermined speed, e.g. 1600 rpm, and the throttle valve is substantially fully closed or the intake manifold vacuum is above a certain level, e.g. -520 to -560 mm Hg, or when the manifold vacuum is above -560 to -600 mm Hg. The switch responsive to manifold vacuum may be influenced by atmospheric temperature and pressure.
