Description

Schlitzspülung beiÄzweitaktbrennkraftmaschinen Bei Zweitaktbrennkraftmaschinen mit Schlitzspülung ist die Regelung der Spülluftzufuhr durch einstellbare Verengung des Spülluftkanals für die jeweils günstigste Spül- wirkung bekannt.Slot flushing beiÄzweitaktbrennkraftmaschinen For two-stroke internal combustion engines with slot flushing is to regulate the purge air by adjustable constriction of the purging air duct for the most favorable flushing effect known.

Die Erfindung betrifft eine durch Baliart und Wirkungsweise besonders einfache und vorteilhafte Einrichtung der Regelung der Spülluftzufuhr der genannten Maschinen.The invention particularly relates to one by Baliart and mode of operation simple and advantageous device for regulating the purge air supply of the aforementioned Machinery.

Als Mittel hierzu wird erfindungsgemäß ein Bolzen benutzt, der in den betreffenden Spülluftkanal eingebaut wird und der in seinem mittleren Teil eine mit seiner Längsachse gleichlaufende Abflachung hat, so daß durch einfaches Drehen des Bolzens um seine Längsachse eine innerhalb bestimmter Grenzen veränderliche Verengung der freien Querschnitte in einfacher Weise bewirkt wird.As a means for this purpose, a bolt is used according to the invention, which is shown in the scavenge air receiver in question is installed and the one in its middle part with its longitudinal axis has the same flatness, so that by simply turning of the bolt about its longitudinal axis a variable within certain limits Narrowing of the free cross-sections is effected in a simple manner.

Eine besonders günstige Ausführungsform wird erfindungsgemüß dadurch erzielt, daß der Bolzen in Anlehnung an eine der Kanalwände so eingebaut wird, daß seineAbflachung für die Stellung der größten Querschnittsfreigabe angenähert in den Linienzug der entsprechenden Kanalbegrenzung hineinfällt.According to the invention, this results in a particularly favorable embodiment achieved that the bolt is installed based on one of the channel walls that its flattening for the position of the greatest cross-sectional clearance approximated in the line of the corresponding channel delimitation falls into it.

In der Zeichnung ist der Erfindungsgegenstand beispielsweise veranschaulicht, und es zeigt Abb. r einen der Spülluftzuleitungskanäle mit eingebautem Bolzen, und zwar für die t,rößte Querschnittsfreigabe, bei der die einzelnen Stromfäden keine Ablenkung erfahren.In the drawing, the subject matter of the invention is illustrated, for example, and Fig. r shows one of the purge air supply ducts with a built-in bolt, and for the t, rößte cross-sectional clearance, in which the individual stream filaments do not Experience distraction.

Abb. 2 zeigt denselben Kanal, aber den dazugehörigen Bolzen in der Lage für die größte Querschnittsverengung. Abb. 3 stellt die Anordnung der Kanäle bei einer Zweizylindermaschine dar, wobei jeder der vier Kanäle einzeln einstellbar ist, und Abb. q. zeigt den abgeflachten Bolzen.Fig. 2 shows the same channel, but the associated bolt in the Position for the largest narrowing of the cross-section. Fig. 3 shows the arrangement of the channels in a two-cylinder engine, with each of the four channels individually adjustable is, and Fig. q. shows the flattened bolt.

Der Arbeitszylinder ist mit a bezeichnet, der Spülluftzuleitungskanal mit b und der Bolzen mit e. Der nicht schraffierte Teil dieses Bolzens stellt den weggenommenen Teil, die Abflachung, dar.The working cylinder is denoted by a, the scavenging air supply duct with b and the bolt with e. The non-hatched part of this bolt represents the removed part, the flattening.

Das Maschinengestell ist mit d und der Spülluftaufnehmer mit e bezeichnet.The machine frame is marked with d and the scavenge air sensor with e.
