Description

Bei Zweitaktmotoren wird der Überströmkanal α in der Regel in den Zylinder eingegossen. Seine Mündung b in den Zylinder, der sogenannte Überströmschlitz, ist schwer zu bearbeiten. Weiter ist die genaue Abmessung dieses Schlitzes für das richtige Arbeiten des Motors von wesentlicher Bedeutung. Vorliegende Erfindung betrifft ein einfaches Verfahren zur Bearbeitung des Überströmschlitzes,In two-stroke engines, the overflow channel α is usually cast into the cylinder. Its opening b into the cylinder, the so-called overflow slot, is difficult to machine. Furthermore, the exact dimension of this slot is essential for the correct operation of the motor. The present invention relates to a simple method for processing the overflow slot,

ίο welches darin besteht, daß mit einem Bohrer c, dessen Durchmesser der vorgeschriebenen Schlitzhöhe entspricht, der Zylinder in Höhe des Überströmschlitzes b annähernd tangential zur Zylinderwand angebohrt wird. Die Eintrittssteile des Bohrers im Auge d (vgl. Abb. 2) wird dann durch einen Gewindepfropfen e geschlossen. Hierauf wird der Zylinder innen, wie üblich, ausgebohrt und dabei auch der Gewindepfropfen, wie aus Abb. 2 ersichtlich, mit-ίο which consists in that with a drill c, the diameter of which corresponds to the prescribed slot height, the cylinder at the level of the overflow slot b is drilled approximately tangentially to the cylinder wall. The entry part of the drill in the eye d (see Fig. 2) is then closed by a threaded plug e . Then the cylinder is drilled out inside, as usual, and the threaded plug, as can be seen in Fig. 2, is also

Der Ansaugschlitz f liegt meistens auf der Seite und muß bisher, da der Vergaser hinter dem Zylinder in der warmen Luft Hegen soll, noch ein besonderes tangential es Verbindungsstück zwischen Ansaugschlitz und Vergaser vorgesehen werden. Nach vorliegender Erfindung kann dies erspart werden, wenn am Zylinder ein tangentialer Anschlußstutzen g direkt angegossen und der Ansaugschlitz / in der gleichen Weise wie der Überströmschlitz b durch tangentiales Ausbohren mittels eines Bohrers h bearbeitet wird.The intake slot f is mostly on the side and, since the carburetor is supposed to lie behind the cylinder in the warm air, a special tangential connecting piece has to be provided between the intake slot and the carburetor. According to the present invention, this can be saved if a tangential connection piece g is cast directly on the cylinder and the suction slot / is machined in the same way as the overflow slot b by tangential drilling using a drill h.
