Description

Mehrzylindrige schlitzgesteuerte Zweitaktbrennkraftmaschine in Blockform Die Erfindung bezieht sich .auf eine mehrzylindrige schlitzgesteuerte Zweitaktbrennkraftmas.chine in Blockform mit in Reihe liegenden Zylindern, bei der die Spülschlitze der einzelnen Zylinder zu beiden Seiten der Auspuffschlitze angeordnet sind. Sie besteht darin, daß durch die einzelnen Zylinderachsen gelegte Symmetrieebenen schräg zur Längsmittelebene der Zylinderreihe liegen und die nebeneinander_ieg:eiiden Spülkanäle zweier benachbarter Zylinder zwischen letzteren in Umfangsrichtung der Zylinder verlaufen.Multi-cylinder, slot-controlled two-stroke internal combustion engine in block form The invention relates to a multi-cylinder, slot-controlled two-stroke internal combustion engine in block form with cylinders lying in a row, in which the flushing slots of the individual Cylinders are arranged on either side of the exhaust ports. It consists in that by the individual cylinder axes laid planes of symmetry obliquely to the longitudinal center plane of the cylinder row and those next to each other: eiiden flushing channels of two adjacent ones Cylinders extend between the latter in the circumferential direction of the cylinder.

Diese Anordnung hat den Vorteil, daß die Zylinderabstände klein werden und daß sämtliche Auslaßschlitze auf einer Seite der Maschine liegen.This arrangement has the advantage that the distances between the cylinders are small and that all of the outlet slots are on one side of the machine.

Ein Ausführungsbeispiel dies Erfindungsgegenstandes ist auf der Zeichnung dargestellt, und zwar zeigt: Abb. I eine schematische Darstellung eines Zweitaktzylinders mit zu beiden Seiten der Auspuffschlitze angeordneten Einlaßschlitzen, in der die Lage der in den nachfolgenden Abbildungen dargestellten Schnitte durch eine Mehrzylindermaschine angedeutet ist, Abb.2 einen waagerechten Schnitt durch den stehenden Zylinderblock der Mehrzyadermaschine in Höhe der Spül- und Auisl,aßschlitze gemäß Linie A-A in Abb. I, Abb.3 einen waag.ereichten Schnitt durch den stehenden Zylinderblock unterhalb der Spül- und Auslaßschlitze ;gemäß Linie B-B in Abb. I .An embodiment of this subject matter of the invention is shown in the drawing shown, namely shows: Fig. I a schematic representation of a two-stroke cylinder with inlet slots arranged on both sides of the exhaust slots, in which the Position of the sections shown in the following figures through a multi-cylinder machine is indicated, Fig.2 a horizontal section through the upright cylinder block of the multi-cycle machine at the level of the rinsing and Auisl, aßschlitze according to line A-A in Fig. I, Fig. 3 a horizontal section through the standing cylinder block below the rinsing and outlet slots; according to line B-B in Fig. I.

Der nachstehend beschriebene Zylinderblock einer Mehrzylinder-Zwcitaktbrennkraftmaschine weist Zylinder zeit einseitiger Umkehrspülung auf, bei denen die Spülis@chlitze u, a gemäß. Abb. I zu beiden Seiten der Auspuffs,chlitze b, b angeordnet sind. Die Spülkanäle c, c verleihen dem in die Zylinder eintretenden Spülluftstrom einen steil gegen die den Auspuffschlitzen gegenüberliegende Zylinderwand gerichteten Verlauf. Gemäß Abb. 2 und 3 .sind die Zylinder d, d1, d2 . .. des Zy- linderblocks derart nebeneinander angeordnet, daß durch ihre Achsen gelegte Symmetrieebenen x-x schräg zu .der Längsmittelebene y-y der Zylinderreihe liegen und die nebeneinanderliegenden Spülkanäle cl, c2 zweier benachbarter Zylinder zwischen letzteren in Umfangsrichtung der Zylinder verlaufen. Der Abstand der Zylinder wird also nur von der Breite eines Spülschlitzes bestimmt, so daß eine sehr gedrängte Bauweise des Motors ermöglicht wird. Dabei liegen sämtliche Auspuffschlitze b; b1, b2... auf einer Seite des Zylinderblo cks.The cylinder block of a multi-cylinder dual-cycle internal combustion engine described below has cylinders with one-sided reverse scavenging, in which the scavenging slits, among others, according to FIG. Fig. I on both sides of the exhaust, slits b, b are arranged. The scavenging channels c, c give the scavenging air flow entering the cylinder a steep course directed towards the cylinder wall opposite the exhaust slots. According to Fig. 2 and 3, the cylinders are d, d1, d2 . .. of the cylinder block arranged next to one another in such a way that planes of symmetry xx laid by their axes are inclined to .der longitudinal center plane yy of the cylinder row and the adjacent flushing channels c1, c2 of two adjacent cylinders run between the latter in the circumferential direction of the cylinders. The distance between the cylinders is only determined by the width of a scavenging slot, so that a very compact design of the engine is made possible. All exhaust ports are b; b1, b2 ... on one side of the cylinder block.

Die obige gestaffelte Anordnung der einzelnen Zylinder ist nicht nur 'bei .der in Abh. I dargestellten einseitigen Umkehrspülung durchführbar, sondern bei allen Maschinen, deren Einlaßschlitze zu beiden Seiten der Auslaßschlitze liegen.The above staggered arrangement of each cylinder is not only 'can be carried out in the case of the one-sided reverse flushing shown in dep on all machines with inlet slots on either side of the outlet slots.
