摘要： The invention relates to an electrically actuated carburetor (1) for gasoline engines, having an air funnel (4) for taking in fuel from a fuel line (2) opening into the air funnel (4), said fuel line being connected to a fuel chamber and comprising a fuel nozzle (3) between the fuel chamber and the opening (5) in the air funnel (4) for adjusting a quantity of fuel that can be drawn in from the fuel chamber due to low pressure in the air funnel (4), flexibly adaptable as a carburetor particularly for motorized tools. In order for the carburetor to overcome the disadvantages of the aforementioned prior art and to have a simple, robust construction allowing constant long-term behavior, at least two Tesla diodes (6, 7) are connected in series with the fuel nozzle (3), between which a pump chamber (8) having a pump unit (9) is located.

摘要： Die Erfindung betrifft ein Verfahren zur Anpassung der Zusammensetzung eines Gemisches (10) aus Kraftstoff und Verbrennungsluft, das einem Brennraum (11) eines gemischgeschmierten Verbrennungsmotors (3) in einem Arbeitsgerät (1) zugeführt ist. Der Kraftstoff wird dem Verbrennungsmotor (3) über ein gesteuertes Kraftstoffventil (13) zugeführt, wobei einem Betriebszustand (I) des Verbrennungsmotors (3) die Kraftstoffmenge durch das Kraftstoffventil (13) zugemessen wird. Zur Anpassung der Zusammensetzung des Gemisches (10) wird der Verbrennungsmotor (3) in einen von dem normalen Betriebszustand (I) abweichenden Sonderbetriebszustand (II) versetzt, wozu der Verbrennungsmotor (3) vom Benutzer zunächst gestartet wird. Nach dem Start wird der Verbrennungsmotor (3) eine vorgegebene Betriebszeit (T min ) in einem ersten Drehzahlbereich (B) betrieben, wobei nach Ablauf der vorgegebenen Betriebszeit (T min ) der Sonderbetriebszustand (II) zur Anpassung der Zusammensetzung des Gemisches (10) durch eine vorgegebene Benutzerhandlung eingeleitet wird.

摘要： The present invention concerns a device for fuel injection intended for an internal combustion engine with a wide range of speeds of revolution and with high requirements for rapid response such as, for example, the engine in a motor cycle, and a method of controlling fuel injection to such an engine. In the invention according to the present application the fuel injection to an internal combustion engine comprising an intake pipe (1) with at least one intake valve (2) and one or more injectors is controlled in such a manner that a first fuel injection in order to obtain a well prepared air/fuel mixture occurs early in the working cycle of the engine following the closure of the intake valve and a second fuel injection in order to obtain an optimal amount of fuel for the cycle, a process known as 'transient compensation', occurs late in the working cycle before closure of the intake valve.
