摘要： A carburetor (1) having a single fuel supply system of a simple construction and capable of stable fuel supply to an engine in an appropriate air-fuel ratio is provided. Air and fuel is mixed to obtain a constant air-fuel ratio in a negative pressure moderating chamber (13) so controlled under negative pressure that adverse effect of air compressibility can be practically negligible. Then, air-fuel mixture and main intake air metered through a main intake air restriction (8) are mixed at the restriction or in a main intake passage (3) downstream thereof. Both the air-fuel mixture and the main intake air are compressible fluids, so that there is a direct proportion between the intake air flow rate and the air-fuel mixture amount injected from the negative pressure moderating chamber (13). Thus, the air-fuel ratio of the mixture composed in said main intake passage (3) is kept constant in all the running operations of the engine. This permits fuel supply with a single supply system.

摘要： Carburettor for an internal combustion engine showing a suction port (1) which is in connection with the combustion chamber of the motor and which is fed with liquid fuel via a nozzle (3) and a fuel channel (3.1), which leads into the suction port (1). A linearly movable valve needle (5) is arranged to extend into the fuel channel (3.1) mainly perpendicular to its longitudinal direction and to open or close this, whereby the suction port (1) is possible to throttle down or close with a throttle (4) which is moveable between an open position and a closed position. The valve needle (5) is in connection with a manoeuvre arm (6), which in turn is in connection with the throttle (4) and is arranged to open the nozzle (3) when the throttle (4) is opened and to close when the throttle (4) is closed.

摘要： An improved carburetor (20) for delivering one combustible fuel and a liquid, or two combustible fuels from separate reservoirs (50), (500), to the central portion of a hollow spray bar (98) for discharge into carburetor venturi (30) includes substantially closed metering chambers (90), (508) disposed in fuel flow communication from the reservoirs and suspended from opposite ends of spray bar (98). Fuels from metering chambers (90), (500), travel through variable width grooves (154), (548) formed in arcuate metering inserts (148), (544) into the lower end portion of corresponding metering arms (92), (540) and then into the hollow interior of spray bar (98). The orientation of metering chamber (90) is regulated to vary the air-fuel ratio by the cooperative action of a vacuum assembly (200) operating in response to the vacuum level in the engine intake manifold (IM), and by both an engine temperature responsive actuating assembly (302) and an intake manifold temperature responsive actuating assembly (304), thereby achieving maximum fuel efficiency and power while minimizing the generation of air pollutants.

摘要： Fuel-air mixture apparatus (1) has a body (2) adapted for connection via a flange (3) to an air cleaner housing (3') and to an engine inlet manifold (4'). In the body (2) is arranged a primary air passage (5) having an inlet (6), an adjustable throttle (7), a throat (8) and an outlet (9). The throttle will be connected in use to a speed control device for the engine via a linkage (10). Also provided in the body (2) is a secondary air passage (13) having an inlet (14) from the air cleaner housing and an outlet (15) to the primary air passage (5) at the throat (8). Towards its downstream end, the secondary air passage opens into a chamber (16), with the opening (17) being arranged tangentially to the chamber to induce swirling air flow in the chamber. The outlet (11) is provided axially of the chamber. At the other end of the chamber, in a bore (18) in the body a nozzle device (21) is provided. It has a circumferential void (24) to the body. This void has a fuel supply bore (25) in the body (2) and connected to a continuous fuel pump opening into it. A fuel inlet (26) leads from the void to an internal bore in the sleeve (22). Slidably mounted in the sleeve is a guide (27), sealed to the sleeve via a gland (28). The outside end of the guide carries a compression spring (29) and the end of the guide is closed by a plug (30) providing an abutment for the spring, whereby the guide is urged outwards. The guide has a bore (31) in which a needle (32) is slidably mounted. The arrangement is such that when the plug (30) is pushed fully inwards of the body, as on closure of the throttle, the needle closes the aperture (38) and the fuel supply to the engine, but the force with which the needle is urged into the aperture is regulated by the internal spring (33). In use, the plug (30) is acted on by an abutment member (40), which is movable in step with the throttle (7) via a branch of the linkage (10). The linkage is designed to ensure that the stoichiometrically required amount of fuel is provided for the throttle opening.

摘要： An apparatus (10) for atomizing liquid fuel while mixing it with air, and varying the amount of each while maintaining a substantially constant fuel/air ratio for the intake manifold of an engine. The apparatus (10) includes a frame (16) forming a passage (14) with a throat (44), with a wall (56) of the passage (14) being moveable toward and away from a stationary wall (54) of the passage (14) to vary the cross-section of the passage (14) and thereby vary airflow. A fuel-carrying tube (24) is fixed to the stationary wall (54) and extends through the moveable wall (56) which is slideable around the tube (24).

摘要： Described is a carburettor (8), comprising an air (2) inlet with a mechanically adjustable air valve (3), an into the air inlet coming mechanically adjustable atomiser, and a mechanical metering device connected with the air valve and the atomiser, maintaining a stoichiometric ratio between amounts of air and fuel. Furthermore the carburettor has fuel pressure regulating means/devices (13) that are equipped to influence the fuel pressure, in dependence of one or more dynamic engine load parameters, under which the vacuum signal in the air inlet, which is obtained via a vacuum intake conduit (12) coming into the air inlet (2). By regulating the fuel pressure also in dependence of the measured vacuum signal, the emission of unburned fuel is reduced under certain dynamic conditions of the combustion engine.
