Description

Zweitakt-Einspritzmaschine (-Dieselmaschine) mit Schlitzspülung Es sind Zweitakt-Dieselmaschinen bekannt, bei denen ein Kolbenspüler derart angeordnet ist, daß er gerade dann fördert, wenn der Arbeitskolben die- Einlaßschlitze im Arbeitszylinder freigibt. Diese Anordnung gestattet die Weglassung des besonderen Drucksteuerkörpers am Spülzylinder und ebenso des besonderen Aufnehmergef,äßes für die Spülluft, führt also zu einer einfachen Bauart, die sich hauptsächlich für kleine Motoren eignet. Eine besonders einfache Kombination ergibt sich, wenn man von zwei parallelachsigen Arbeitszylindern ausgeht, die um eine halbe Umdrehung versetzt auf eine Kurbelhelle arbeiten. Ein solches Zylinderpaar ist in Abb. i beispielsweise dargestellt. An den Kurbeln ,! und B hängen außer den Schubstangen für die beiden Arbeitskolben zwei weitere S.chubstangen, durch welche die beiden angetrieben werden. Die beiden Spülzylinder stehen ebenfalls parallelachsig nebeneinander, jedoch stehen die Spülzylinder und Arbeitszylinder in V-S.tellung zueinander, wie aus Abb.3 ersichtlich. Wenn man nun die Spülzylinder über Kreuz in die beiden Arbeits@-zylinder fördern läßt, d. h. wenn man den an Kurbel -4 hängenden Spülkolben in den zu Kurbel B gehörenden Arbeitszylinder und den an Kurbel B hängenden Spülkolben in den zu Kurbel A gehörenden Arbeitszylinder fördern läßt, so fallen die Förderperioden der Spül- zylinder mit den Spülperioden der Arbeitszylinder gerade zusammen. Die Drucksteuerorgane der Spülzylinder und der Aufnehmer können wegfallen.Two-stroke injection machine (diesel engine) with slot scavenging Two-stroke diesel engines are known in which a piston scavenger is arranged in such a way that it delivers when the working piston releases the inlet slots in the working cylinder. This arrangement permits the omission of the special pressure control element on the flushing cylinder and also of the special receiving vessel for the flushing air, thus leading to a simple design which is mainly suitable for small engines. A particularly simple combination is obtained if one starts from two parallel-axis working cylinders that work on a crank shaft offset by half a turn. Such a pair of cylinders is shown in Fig. I, for example. On the cranks! and B, in addition to the push rods for the two working pistons, hang two additional push rods, through which the two are driven. The two rinsing cylinders are also parallel to each other, but the rinsing cylinders and working cylinders are in a position opposite to one another, as can be seen in Figure 3. If you can now promote the flushing cylinder crosswise into the two working cylinders, ie if you can promote the flushing piston hanging on crank -4 in the working cylinder belonging to crank B and the flushing piston hanging on crank B in the working cylinder belonging to crank A , the delivery periods of the rinsing cylinders coincide with the rinsing periods of the working cylinders. The pressure control elements of the rinsing cylinder and the sensor can be omitted.

Abweichend von Maschinen mit Kurbelkastenspülung können die Spülkolben so groß gemacht werden, daß eine ausreichende Luftmenge für die Spülung zur Verfügung steht. Der 1-eistungsgewinn durch die Vervollkommnung der Spülung überwiegt erheblich die durch die Anordnung besonderer Spülkalben hervorgerufene Verteuerung. außerdem kommen andere Nachteile der Kurbelkastenspülung in Wegfall, wie die Schmierung durch mehrstemplige Pumpen, die lästige Gehäuseabdichtung und besonders die Notwendigkeit, zwischen den beiden Arbeitskurbeln ein Lager und .eine dichtende Gehäusewand an7uordnen.In contrast to machines with crankcase flushing, the flushing pistons be made so large that a sufficient amount of air is available for flushing stands. The 1-performance gain through the perfection of the flush outweighs considerably the increase in price caused by the arrangement of special flushing calves. aside from that there are no other disadvantages of crankcase flushing, such as lubrication multi-stem pumps, the annoying housing seal and especially the need to To arrange a bearing and a sealing housing wall between the two working cranks.

Ähnliche Anordnungen von Arbeits- und Pumpenzylindern zueinander sind für Gemis-chlademaschinen versucht worden. Sie sind aber daran gesäheitert, daß der wesentliche Vorteil der Bauart, nämlich die Möglichkeit, die Spülpumpe ausreichend groß zu machen, bei Gemischlademaschinen nicht ausgenutzt werden kann.Similar arrangements of working and pump cylinders to each other are has been tried for Gemis loading machines. But you are cheered up on the fact that the main advantage of the design, namely the ability to use the flushing pump adequately to make large, can not be exploited in mixture loading machines.
