    摘要： A four cylinder spark ignition internal combustion engine has an exhaust emission control system including means for admitting fresh air into the exhaust system in order to promote a further combustion of partly burnt components in the gases coming from the combustion chambers, this means include a "reed" valve connected to the exhaust ports leading from the first and fourth cylinders (numbering from one end of the engine) through internal passages within the cylinder head; the system also comprises an exhaust gas recirculating system comprising a pneumatic valve which opens, when the conditions are appropriate, to draw off a proportion of the exhaust gases from the exhaust side of the engine and admit them to the induction side of the engine taking exhaust gases from branches of the exhaust manifold carrying exhaust gases from the second and third cylinders; in addition there is a system for admitting supplementary air to the induction manifold downstream of the carburettor during engine overrun conditions except when the engine is cold, and the carburettor is provided with supplementary pumps and valves which only function when the engine is cold, being inhibited as the engine approaches its normal working temperature.

    摘要： A carburetor is provided with a flow control valve in a fuel discharge passageway leading from an acceleration pump to an air induction passage. The valve is pressure responsive and reduces effective cross sectional area of the passageway in response to pressure in the passageway, the pump discharge pressure.

    摘要： An enrichment device for a charge forming system for an internal combustion engine that is responsive to induction system pressure for effecting a pumping action to draw fluid in when the engine is operating in a steady state condition and to discharge fluid for enrichment when the engine is being accelerated. The system includes a series of interrelated pressure sensing chambers for controlling the operation of the pump to avoid fluctuations during small variations in induction system pressure but to permit rapid and immediate pumping action upon sudden pressure changes.

    摘要： The invention relates to a fuel metering and distribution system for an internal combustion engine comprising an open fuel reservoir 18 into which fuel is metered and a set of capillary tubes 20 each extending from the fuel reservoir 18 to a point in an induction manifold adjacent the intake valve of a respective one of the engine cylinders. The fuel may either be metered by a carburettor-like arrangement drawing fuel from a float chamber or by means of a single solenoid valve connected between the reservoir and a source of fuel under pressure. The ends of the fine tubes terminate in the fuel reservoir immediately above the fuel level, whereby as the fuel rises, the additional fuel metered into the reservoir is sucked into the fine tubes and transferred directly to the engine cylinders.
