摘要： A valve (41) comprises an inlet (43), a first outlet (49) and a second outlet (55). A first valve member (57) of the valve (41) cooperates with a valve seat (59) of the first outlet (49), and a second valve member (61) of the valve (41) cooperates with a valve seat (63) of the second outlet (55). The first and second valve members (57, 61) are provided on a common driving shaft (67) which is displaceable by an electric actuator (69) to regulate an air flow through the first outlet (49) and an air flow through the second outlet (55). The first and second valve members (57, 61) are combined into a single integrated valve member (65) which cooperates with both the valve seat (59) of the first outlet (49) and the valve seat (63) of the second outlet (55). A simple and compact structure of the valve (41) is obtained in this manner. The valve (41) is used in an air-assisted fuel-injection system (3) of an internal-combustion engine (1), wherein the first outlet (49) of the valve (41) is connected to a bypass (51) of a throttle valve (29) of the engine (1) and the second outlet (55) of the valve (41) is connected to an air-assisted fuel injector (31) of the fuel-injection system (3). In this manner, both the atomization of the fuel injected by the fuel injector (31) and the idling speed of the engine (1) are controlled by a single valve (41).

摘要： A manifold for a fuel-injected engine has several fuel injectors that are connected to a common air assist passageway for each bank of cylinders. This passageway is preferably supplied with assist air from a central location, between two of the fuel injector pockets that intersect the air assist passageway in each bank of cylinders. This air assist passageway may be formed integral with a manifold, or, may be separately formed together with the injector pockets as an air assist rail.
The air assist passageway preferably intersects the center line of the fuel injector pockets and is formed by inserting pins that define the interior surface of the passageway into a mold cavity to intersect and pass through bosses that define the fuel injector pockets.

摘要： Bekannte Brennstoffzuführsysteme besitzen ein Einblaseventil, das ein Brennstoff-Luft-Gemisch direkt in einen Brennraum abgeben kann. Werden aber große Einspritzmengen abverlangt, wie dies beispielsweise bei hohen Motorlasten der Fall ist, kann es zu Problemen bei der Güte der Gemischaufbereitung kommen.
Es wird ein Brennstoffzuführsystem für eine fremdgezündete Brennkraftmaschine vorgeschlagen, das zumindest ein in oder an einem Zylinderkopf angeordnetes Einblaseventil besitzt, dem Brennstoff und ein gasförmiges Medium unter Druck zugeführt wird, um mittels des Einblaseventils ein Brennstoff-Medium-Gemisch direkt in einen Brennraum der Brennkraftmaschine abzugeben. Erfindungsgemäß ist zumindest ein weiteres Einspritzventil vorgesehen, welches bei bestimmten Betriebsbereichen der Brennkraftmaschine zusätzlich zur Abgabe des Brennstoff-Medium-Gemisches mittels des Einblaseventils oder zeitweise anstelle der Abgabe des Brennstoff-Medium-Gemisches mittels des Einblaseventils Brennstoff in einen Ansaugbereich der Brennkraftmaschine abgibt.
Das erfindungsgemäße Brennstoffzuführsystem ist für fremdgezündete Brennkraftmaschinen vorgesehen.

摘要： Two-stroke motor comprising at least: one cylinder (111) within which is displaced a piston (112), one of the cylinder ends communicating with a pump housing (115) through which passes the crankshaft; a pressurized duct (87) opening at one end into the combustion chamber (113) of the cylinder (111), at least one valve (86) periodically sealing the chamber (113) from the duct (87); means (88) for carburizing the gas passing through the duct (87); means for controlling opening of the valve (86) comprising one flexible diaphragm (89) which separates two chambers (95a, 95b) and is linked to the valve rod. According to the invention, the engine further comprises means for connecting (92) one (95b) of the chambers of the pump housing (115) of the cylinder, in particular, for triggering opening of the valve (86) at the earliest when the pressure PB within the chamber (95b) falls below the pressure PS within the duct (87).

摘要： In a device for regulating the idling speed of an internal combustion engine (12) by controlling the quantity of fuel which can be supplied from a fuel tank (10) to the engine via at least two supply lines, the cross-section of a first valve aperture (34) is controlled by a first valve closing member (38a) and that of a second valve aperture (36) is controlled by a second valve closing member (38b). The first and second valve closing members (38a, 38b) can be moved by a servo-drive in such a way that the first and second valve apertures are arranged mutually parallel between the fuel tank and the engine's intake passage. The valve closing members (38a, 38b) are coupled in such a way that, when they are actuated, the first valve closing member (38a) always opens a flow cross-section to the first valve aperture (34) and only then does the second valve closing member (38b) open a flow cross-section to the second valve aperture (36).
