    摘要： A downdraught carburettor of the constant pressure type has a mixing chamber 2 with an operator-controlled throttle valve 3 at its downstream end and a choke valve 10, which is operated by a diaphragm box 20 in dependence upon the pressure in the mixing chamber 2, at its upstream end. Fuel is supplied to the mixing chamber from an annular duct 5 through ports 6 to the wall of the mixing chamber down which the fuel flows in the form of a thin film. The film is evaporated to form the mixture by a heating jacket 16 which surrounds the mixing chamber 2 and is heated by engine cooling water or exhaust gases. In order to prevent the film of fuel from being broken up before it has been heated and evaporated, which tends to happen owing to turbulence in the air stream caused by the choke valve 10, an inner tube 11 is provided. The choke valve 10 is situated in the upstream end of the inner tube 11 so that the fuel film is screened by the tube 11 from any turbulence caused by the valve 10. Air flow to draw fuel from the ports 6 and build up the film on the wall of the mixing chamber takes place through narrow annular ducts 12 between the tube 11 and the surrounding mixing chamber wall, these narrow ducts being uniformly spaced apart around the whole of the outside of the tube 11.

    摘要： A variable venturi carburetor is described that functions in relation to an internal combustion engine to deliver a homogenous mixture of hydrocarbon fuel and air to the engine cylinders in response to vacuum pressure created through the cylinders. The carburetor includes axially movable venturi members for effectively changing the air volume entering through the primary air duct. Provision is made for maintaining a preselected volume of raw fuel available in a reservoir for instantaneous delivery in response to demand created through various throttle opening conditions. In addition to this feature, I provide mechanism by which the air-fuel ratio is appropriately adjusted automatically in response to changing throttle positions. This is done by changing the "head" or distance from the fuel reservoir level to the fuel outlet orifice, thereby changing the pressure requirements for drawing the fuel from the reservoir to the outlet orifice. A further provision is made in the form of a barometric sensing device that is operatively connected to the carburetor in order to automatically vary the air-fuel ratio in response to varying air pressure conditions at various altitudes.

    摘要： A fuel delivery system for an internal combustion engine includes induction conduits of effectively equal flow resistance for guiding separate air and fuel streams to each of the cylinders of the engine. Each induction conduit includes at its entrance a sleeve venturi for inducing fuel into the air stream and a booster venturi. A fuel injector applies fuel at high pressure to the booster venturi. Flow modifiers may be positioned in the venturi throat and down stream of the venturi for modifying the flow of the stream of air after the fluid has been induced and injected into the stream of air for further subdividing the fuel vapor for increased effect of combustion of the fuel and air mixture.

    摘要： A variable venturi carburetor has a vertically movable head which moves along the downwardly extending induction passage. The movable head includes a lower member whose vertical position is determined by an accelerator pedal for the engine on which the carburetor is adapted and an upper member defining within the induction passage an annular venturi zone and being vertically movable relative to the lower member to vary the cross sectional area of the venturi zone in response to the negative pressure developed behind the venturi zone within the induction passage. Thus, the venturi zone area is varied depending on the depression of the accelerator pedal as well as the negative pressure indicative of the ongoing engine condition such that an optimum amount of fuel is drawn therefrom to efficiently operate the engine throughout the operational range of engine RPM and load conditions. At a starting condition, more fuel is initially fed to the venturi zone through a power jet which opens in response to the introduced atmospheric pressure behind the venturi zone just before the engine starting as well as through an ever-opened main jet, whereby, in addition to more powerful suction being developed by a minimum venturi area caused by the relative movement of the upper member in response to such atmospheric pressure in the engine, produces a very rich mixture enough to start the engine without using the conventional choke valve.

    摘要： A constant pressure carburettor comprises a mixing chamber 2 which is surrounded by a heating jacket 12, an operator controlled throttle valve 3 at the downstream end of the chamber 2, a fuel feeder 5, 6 at the upstream end of the mixing chamber and a choke valve 10 at an air inlet to the carburettor. The choke valve 10 is, in use, controlled automatically by the air flow into the carburettor in dependence on the opening of the throttle valve 3 and the speed of the engine to which the carburettor is fitted. The choke valve 10 tends to produce vortices or turbulence in the air flow and this tends to cause the fuel supplied by the feeder 5, 6 to the wall of the chamber 2 to be prematurely removed before it is heated. This adversely affects the vaporization of the fuel and the formation of the air-fuel mixture. To avoid turbulence or vortices in the chamber 2, a stabilization conduit 16 is provided between the choke valve 10 and the fuel feeder 5, 6. The conduit 16, which preferably has two right-angle bends as shown, damps out or at least decreases the vortices or turbulence in the air flow before it reaches the mixing chamber 2.
