Description

Verfahren zum Betrieb von gemischverdichtenden, selbstzündenden Zweitakt-Brennkraftmaschinen Es sind selbstzündende Brennkraftmaschinen bekannt, bei denen dem Treibstoff zündfördernde Stoffe, insbesondere Äther, zugesetzt werden und dieser Treibstoff über einen Vergaser dem Zylinder zugeführt wird. Demgegenüber besteht die Erfindung darin, daß einer Zweitakt-Brennkraftmaschine Schweröl (Gasöl, Dieselöl, Petroleum usw.) über eine Zumeßvorrichtung zusammen mit Luft dem Kurbelgehäuse zugeführt, durch die umlaufenden Teile des Kurbelgehäuses verteilt und mit Luft gemischt dem Verbrennungsraum zugeführt wird.Method for operating mixture-compressing, compression-ignition two-stroke internal combustion engines Self-igniting internal combustion engines are known in which the fuel promotes ignition Substances, especially ether, are added and this fuel via a carburetor is fed to the cylinder. In contrast, the invention is that one Two-stroke internal combustion engine heavy oil (gas oil, diesel oil, petroleum, etc.) via a Metering device supplied together with air to the crankcase, through the rotating Parts of the crankcase distributed and mixed with air fed to the combustion chamber will.

Das neue Arbeitsverfahren bringt zwei wesentliche Vorteile. Einmal ist die Beimischung eines zündfördernden Stoffes zum Treibstoff nicht erforderlich, und zweitens entfällt der Vergaser. Das Schweröl wird bei der Zweitakt-Brennkraftmaschine über eine Zumeßvorrichtung zusammen mit Luft dem Kurbelgehäuse zugeführt und hier zunächst von den sehr rasch umlaufenden Triebwerkteilen zerschlagen. Die Durchwirbelung innerhalb des Kurbelgehäuses bringt eine innige Vermischung des zerteilten Öles und der Luft zustande. Das so vorbereitete Gemisch wird im Kurbelgehäuse vorverdichtet und dringt bei der entsprechenden Kolbenstellung in den Zylinderraum ein, wo es sich bei der Kompression einwandfrei entzündet.The new working method has two main advantages. Once it is not necessary to add an ignition-promoting substance to the fuel, and secondly, there is no carburetor. The heavy oil is used in the two-stroke internal combustion engine fed to the crankcase via a metering device together with air and here initially smashed by the rapidly rotating engine parts. The vortex inside the crankcase brings about an intimate mixing of the divided oil and the air. The mixture prepared in this way is pre-compressed in the crankcase and penetrates at the corresponding piston position in the cylinder space, where it ignites perfectly on compression.

Es ist zweckmäßig, die Maschine mit Luft zu kühlen, damit der Zylinder eine relativ hohe Temperatur erhält und.sich kein 01 an ihm niederschlagen kann.It is advisable to cool the engine with air so that the cylinder receives a relatively high temperature und.sich no 01 can be deposited on it.
