摘要： A dual fuel engine includes an engine operable on a gaseous fuel and a liquid fuel and a switch to change operation of the engine between gaseous fuel and liquid fuel. The dual fuel engine also includes a carburetor attached to an intake of the engine to mix air and fuel and connect to a gaseous fuel source and a liquid fuel source. A liquid fuel cut-off attaches to the carburetor to interrupt liquid fuel upon actuation of the switch from liquid fuel to gaseous fuel.

摘要： A carburettor for an internal combustion engine has an air passageway in which air flow is controlled by a poppet valve in which fuel is fed from a tapered needle controlled valve readily variable for different fuels including CNG, LPG, Methanol and petrol. A movable assembly comprises the poppet valve connected to a movable wall, the latter separating a first and second pressure chamber and a low pressure control valve is manually programmable to take up a position relative to the movable assembly preferably the movable wall to control pressure in the first pressure chamber against a balancing pressure in the second pressure chamber and a biasing means to control the position of the poppet valve and the fuel valve and hence the power of an internal combustion engine on which the carburettor is fixed in accordance with selected positions of a manual control.

摘要： A carburetor apparatus having an improved fuel metering arrangement comprises a generally cylindrical housing, a nozzle disposed within the housing and rotatable about an axis coincident with that of said housing, the nozzle being movable along the axis between an upper position and a lower position in response to the flow of air through the housing, a support for rotatably supporting the nozzle, the support including a tubularly-shaped member having an axial passageway formed therein coincident with the axis, a guide for permitting the tubular member to move along the axis with the nozzle and a spring for biasing the tubular member in the direction of the upper position, the tubular member having an inlet to the passageway provided near one end and having the nozzle rotatably affixed to the other end, a valve seat formed along the passageway between said inlet and said other end, a valve needle disposed along the axis and extending into the passageway through the one end, the needle cooperating with the valve seat to form a valve for throttling the flow of fuel through the passageway as the nozzle moves between upper and lower positions, and means affixed to the housing for selectively positioning the valve needle along the axis, the position of the needle along the axis being operative to calibrate the fuel throttling for particular environmental conditions. A pressure regulation system controls the pressure of the fuel entering the inlet, and seals prevent fuel from entering the engine area.

摘要： In a carburetor, three downstream body passages in the body communicate with three valve passages in the valve element, and the valve element rotates between a closed position and an opened position. The carburetor is a one-bore type carburetor in which the body passages and the valve passages are respectively partitioned with the body partitions and the valve partitions. When rotating the valve element from the closed position to the opened position, the second body passage and the second valve passage for mixture start to communicate in advance than the first and third body passages and the first and third valve passages for air.

摘要： A carburetor of an internal-combustion engine in an automotive vehicle has at least one main duct and an ancillary duct supplying an air/fuel mixture to a manifold, the fluid flow through the ducts being controlled by an accelerator via ganged butterfly valves of which the one in the main duct closes completely whereas the one in the ancillary duct closes only partially in an idling position. Separate nozzles deliver fuel to the main duct at a higher hydrostatic head and to the ancillary duct at a lower hydrostatic head, thereby preventing the aspiration of an excessive amount of fuel by the piston cylinders upon deceleration of the vehicle or during idling. The fuel is admitted to the ducts, between a Venturi throat and the butterfly valves, by nozzles fed from a common float-controlled pressure regulator, or from two such pressure regulators, to which the fuel is delivered by gravity from a buffer reservoir also provided with a float valve and connected to the high-pressure side of a fuel pump. In order to avoid unduly lean mixtures in the wide-open position of the butterfly valves, the airstream entering the ancillary duct may be precharged with fuel vapor by being forced to pass through a pool of fuel before reaching that duct. The buffer reservoir has an overflow line leading to the low-pressure side of the pump, directly or via the fuel tank. A check valve, operated by toggle action or by simple flotation, is inserted in the overflow line to prevent reverse surges to the buffer reservoir.
