Description

Die Erfindung betrifft einen Zweitaktmotor mit Kurbelkastenpumpe und einem die Fördermenge dieser Pumpe vergrößernden, ebenso wie der Arbeitskolben auf den Kurbelkasten wirkenden Zusatzkolben, bei dem zum Ansaugen der Ladung in den Kurbelkasten ,sowohl der Arbeitskolben als auch der Zusatzkolben je eine oder mehrere Öffnungen aufsteuern.The invention relates to a two-stroke engine with a crankcase pump and one that increases the delivery rate of this pump, as does the working piston The additional piston acting on the crankcase is used to suck the load into the Crankcase, both the working piston and the additional piston each one or more Open openings.

Es ist Aufgabe der Erfindung, einen Zweitaktmotor der vorbeschriebenen Art zu verbessern. Dies wird dadurch erreicht, daß den Öffnungen ein gemeinsamer Ansaugkanal vorgeschaltet ist.It is an object of the invention to provide a two-stroke engine as described above Kind of improve. This is achieved in that the openings have a common Intake channel is connected upstream.

Durch die Erfindung wird in baulicher Hinsicht ein besonders einfacher Motor geschaffen, bei dem die Zuführungskanäle kurz werden und bei dem nur ein einziges Ansaugfilter erforderlich ist.In structural terms, the invention makes a particularly simple one Engine created in which the supply channels are short and in which only a single one Suction filter is required.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt. Die Abb. i zeigt einen Zweitaktmotor mit Kurbelkastenpumpe von vorn gesehen in einem senkrechten Schnitt; die Abb. 2 zeigt einen Schnitt nach der Linie II-II der Abb. i ; in Abb. 3 ist der Schnitt nach Abb. i durch die Linie I-I angedeutet.In the drawing, an embodiment of the invention is for example shown. Fig. I shows a two-stroke engine with a crankcase pump from the front seen in a vertical section; Fig. 2 shows a section along the line II-II of Fig. I; in Fig. 3 the section according to Fig. i is indicated by the line I-I.

Es bezeichnet i den Arbeitskolben, 2 die Pleuelstange, 3 die Kurbelwelle, q. den Zylinder und 5 das Kurbelgehäuse eines Zweitaktmotors. Der Zweitaktmotor arbeitet zwecks Spülung mit Kurbelkastenpumpe. Zur Vergrößerung der Fördermenge der Kurbelkastenpumpe hat der Zweitaktmotor noch einen Zusatzkolben 6 mit Zylinder 1,¢, der wie der Arbeitskolben i auf den Kurbelkasten 7 wirkt. Der Zusatzkolben 6 wird von einem neben der Kurbel 8 der Kurbelwelle 3 auf der Kurbelwelle sitzenden Exzenter 9 angetrieben. Zur Vergrößerung der Ansaugleistung steuert sowohl der Arbeitskolben als auch der Zusatzkolben je eine Öffnung io bzw. ii auf. Zur Ansaugung der frischen Ladung steht also auf diese Weise ein großer Zeitquerschnitt zur Verfügung, so daß eine gute Füllung der Kurbelkastenpumpe gewährleistet ist. An Stelle einer Öffnung io bzw. I I können auch deren mehrere vorgesehen werden.It denotes i the working piston, 2 the connecting rod, 3 the crankshaft, q. the cylinder and 5 the crankcase of a two-stroke engine. The two-stroke engine works with a crankcase pump for the purpose of flushing. To increase the delivery rate of the crankcase pump, the two-stroke engine also has an additional piston 6 with cylinder 1, [which acts like the working piston i on the crankcase 7. The additional piston 6 is driven by an eccentric 9 seated on the crankshaft next to the crank 8 of the crankshaft 3. To increase the suction power, both the working piston and the additional piston each open an opening io or ii. In this way, a large amount of time is available to suck in the fresh charge, so that a good filling of the crankcase pump is guaranteed. Instead of one opening io or I I , several can also be provided.

Zur Vereinfachung der Bauart des Motors ist den Öffnungen io und ii ein gemeinsamer Ansaugkanal vorgeschaltet. Der Ansaugkanal 1:2 ist als Ringkanal des Kurbelgehäuses 5 ausgebildet und liegt auf der vom Exzenter 9 abgewandten Seite der Kurbel B. Das zur Ansaugung notwendige Luftfilter 13 ist seitlich des Motors an den Ansaugkanal 12 angeschlossen.To simplify the design of the engine is the openings io and ii a common intake duct is connected upstream. The intake duct 1: 2 is an annular duct of the crankcase 5 and is on the side facing away from the eccentric 9 the crank B. The air filter 13 required for suction is on the side of the engine connected to the intake duct 12.
