    摘要： A combined accelerator pump 14 and cold start fuel/air mixture supply device 15 has an automatic throttle valve 21 in a mixture supply passage 17, a fuel control valve 53 controlling flow of fuel drawn into the passage 17 through an inlet 52 upstream of the throttle valve 21, and an air valve 23 upstream of the fuel inlet 52. A primary spring 32 tends to seat the air valve 23. A light, secondary spring 36 urges a plunger 25 against the air valve 23 to augment the load of the primary spring 32 for a predetermined time interval after the engine begins to run under its own power. A valve in a pipe 34 opens automatically at the end of the predetermined time interval to apply engine inlet manifold depression to the end of the plunger 25 remote from the air valve 23 and thereby to separate the plunger 25 from the air valve 23 so that only the primary spring 32 acts on the air valve 23.

    摘要： An automatic cold start fuel supply device comprises a needle (67) movable with engine temperature by a bimetallic element (57) via a rotary member (51). A spring (74), which is normally compressed by the action of manifold depression on a diaphragm (72), acts when expanded through the diaphragm (72) and a lever (76) on an arm (53) of the rotary member (51). The geometry of the lever (76) and the rotary member (51) is such that the rotary member (51) is so positioned by the bimetallic element (57) when the engine is warm that it is not rotated by the load that is applied to its arm (53) by the action of the spring (74) whereas it is so rotated against the action of the bimetallic element (57) when the engine temperature is below the normal running temperature.

    摘要： An electronic control unit is used to control the opening period of a single point fuel injector by means of the generation of a fuel metering electrical pulse. The pulse length is determined by the sensing of inter alia engine loading (e. g. air flow rate or absolute manifold pressure) and engine speed. The engine loading signal is sampled at fixed intervals and average over the samples taken between engine firings. The number of samples used in the averaging procedure reduces with increasing engine speed.
    An acceleration enrichment procedure is also conducted by the control unit comprising a proportional increase in pulse width for a number of cycles followed by a smaller increase over successive cycles.

    摘要： Injecteur de fluide à actionnement electromagnétique comprenant une chambre de carburant (44) possédant un ajutage de sortie (15) et dans laquelle fait saillie un noyau de solénoïde (28). Une soupape à bille (41) située dans l'interstice entre le noyau (28) et l'orifice de l'ajutage peut se déplacer vers le noyau (28) et s'en écarter sous l'effet de la mise sous tension d'un circuit électromagnétique, de manière à reposer ou s'écarter d'un siège de soupape (39) autour de l'orifice de l'ajutage. Des organes de compensation réagissent aux changements de température en modifiant une caractéristique physique. Les organes de compensation permettent soit de modifier la longueur du noyau (28), soit d'ajuster la position du siège de soupape (39) par rapport au noyau (28) de manière à contrecarrer toute tendance des caractéristiques de mesure de carburant de l'injecteur à être modifiées par un changement de la température dans l'injecteur, rendant ainsi le fonctionnement de l'injecteur indépendant des changements de température.

    摘要： A single point fuel injection air/fuel metering device comprising a tubular housing 12 with a flap 16 pivotally mounted therein upstream of a throttle valve 14. The flap 16 is dynamically balanced about its pivot axis 17 which is offset from the axis of the tubular housing 12, and is wholly within the bore of the tubular housing 12 throughout its range of angular movement. A flap return spring 18 which is anchored in the tubular housing 12 upstream of the flap 16 acts at the centre of area of the flap 16. A rotary damper spindle and a rotary potentiometer spindle project coaxially into the housing bore 13 from opposite sides thereof and the flap 16 is clamped to them so that it is supported by the low friction bearings of the damper and the potentiometer. An injector 23 is mounted to inject fuel into the bore 13 between the flap 16 and the throttle valve 14.

    摘要： Electronic control apparatus for controlling fuel supply to a spark ignition i.c. engine includes a microprocessor based control unit developing fuel metering pulses controlling the opening of an injector valve. The timing of the delivery of the pulses to the injector is controlled by a look-up table in memory so that there is zero delay between top dead centre position of the crankshaft and the valve opening at low speeds but increasing delay, up to 66° with increasing engine speeds. This control improves fuel utilisation.

    摘要： A motor vehicle LPG fuel system includes a pair of digital injection valves in a body (23) having a common inlet (17), a common outlet (18) and an outlet chamber into which the gaseous LPG is injected alternately by the two valves. The metered pulsed outputs of the two valves collected in the outlet chamber is conveyed as a single gaseous fuel supply to the carburetter induction passage (10). The injection valves can be located spaced from the carburetter (11) whereby to avoid excessive heating. An electronic control unit (19) including a microprocessor and a data store matrix responds to certain engine operating conditions, including engine speed and engine loading, and controls alternate operation of the valves in synchronism with the engine ignition firing sequence. Under certain conditions one of the valves may open before the other closes.
