摘要： The invention relates to an injection device (1), designed in particular for injecting fluid into an exhaust tract of an internal combustion engine, having a valve needle (14), an injection chamber (12) having at least one injection opening (44), and a control chamber (20). The injection device (1) is designed such that a pressure differential between the injection chamber (12) and the control chamber (20) brings about a displacement of the valve needle (14) between an open position in which a fluid flow through the injection opening (44) from the injection chamber (12) is released, and a closed position, in which the injection opening (44) is closed off. The injection chamber (22) and the control chamber (20) are hydraulically connected to an inlet (40, 42; 9), such that a pressure rise in the inlet (40, 42; 9) results in a pressure rise in the injection chamber (12), and a pressure rise in the control chamber (20) delayed in time relative to the pressure rise in the injection chamber (12), and said pressure differential brings about a displacement of the valve needle (14) from the closed position into an open position.

摘要： A carburetor including a carburetor body (22) having a throat (24) extending from an intake (26) to a discharge (28), and a fuel nozzle (32) positioned within the throat and including an upstream orifice facing substantially upstream and a downstream orifice facing substantially downstream. A surface area of the upstream orifice is smaller than a surface area of the downstream orifice. If more than one orifice is provided on each side, a combined surface area of all upstream orifices is less than a combined surface area of all downstream orifices. The upstream orifice is positioned closer to the carburetor body than any of the downstream orifices. The downstream orifice includes a plurality of downstream orifices that have an average position that is centered with respect to the throat.

摘要： An idle fuel supply device for a carburetor has an idle air passage (2) that communicates with an air intake passage (30) and a fuel chamber (27). A passage (2) extending from a fuel metering chamber (13) is connected to the fuel chamber (27) preferably via a fuel adjusting needle valve (31). A low speed fuel nozzle hole communicates the fuel chamber (27) with the air intake passage (30) in the vicinity of a throttle valve (24) when in its idle position. A passage communicates with the fuel chamber (27) and the idle air passage (2), so that fuel and air may mix in at least a portion of the idle air passage (2).
