    摘要： A fuel metering arrangement in devices for pneumatically assisted direct fuel injection into an internal combustion engine cylinder head (12) provided with a chamber (19) housing a connecting rod (23) for operating a compression piston (24) slidingly guided within a jacket (25) provided with one or more transfer conduits (26) connecting said internal chamber (19) to a variable-dimension space (27) positioned downstream of the piston (24) and upstream of a valve (28) providing access to a combustion chamber (29), fuel feed means (31, 33, 35) being connected to said variable-dimension space (27). In this manner a very rapid transient is achieved during acceleration.

    摘要： It is known that enriching fuel with oxygen improves combustion and thus reduces fuel consumption, improves performance and reduces pollutant and soot particle emission. In order to prevent the air admixed into the fuel before the air is introduced into the combustion chamber from forming air bubbles in the supply pipe, the fuel-air mixture is selectively degassed depending on the size of the air bubbles. The fuel is fed by a feed pump (4), through a suction pipe (2), from a tank (1) into an apparatus (3), and from there into an internal combustion engine (5). Air is admixed by device (6). The apparatus (3) contains a degassing chamber (7) with a floater (8) that closes the lower admission (10) with a sealing cone (9) and that controls with an actuating pin (11) an inlet valve (12) depending on the level of fuel in the chamber.

    摘要： Pneumatically-controlled fuel injection in a two-stroke engine comprising at least one cylinder (1) with a piston (2) delimiting a combustion chamber (14) and a pump housing (5) located in the extension of the combustion chamber and separated therefrom by the piston (2), at least one main air inlet (7) located within the pump housing, including a first backflow preventor (6), a device for supplying the pressurized air-fuel mixture, including means (20) for opening and closing an opening (12) for introducing the air-fuel mixture into the combustion chamber (14), and a channel (15) linked to the opening (12), containing the pressurized air-fuel mixture. The engine of the invention also comprises means (30-34) for drawing and introducing a pressurized fuel-air mixture into the channel (15).

    摘要： Es wird eine Brennstoffversorgungseinrichtung für gemischverdichtende Brennkraftmaschinen vorgeschlagen, bei der die Dosierung der Brennstoffmenge mittels eines von einer Steuerelektronik (5) gesteuerten elektromagnetischen Einspritzventils (10) erfolgt.
    Die Einrichtung umfaßt eine Brennstoffdosiervorrichtung und eine Flügelzellenpumpe (7) zur Förderung eines Teilluftstromes (6), der den Brennstoff durch Transportleitungen (20) in das Ansaugrohr der Brennkraftmaschine fördert.
    Das Einspritzventil (10) spritzt den dosierten Brennstoff stromab des Lufteintritts in eine Kammer der Flügelzellenpumpe (5) ab.
