Description

Zweitaktmotor Es sind Vier- und Zweitaktbrennkraftmaschinen bekannt, bei welcher jeder einzuführenden Ladung ein Quantum Spülluft in den Verbrennungsraum vorausgeschickt wird, zum Zweck der Ausspülung der Abgase und Verhinderung der Gemischvexschlechterung dadurch, daß ein Teil. der Abgasreste sich dem Frischgemisch beimischt. Die Erfindung betrifft eine Anwendungsform dieser Vorrichtung an dem Gegenstand des Patents 422 393. Die- Abb. i stellt einen beispielsweisen schematischen Längsschnitt durch eine solche Kraftmaschine dar, während die Abb. 2 und 3 Schnitte durch die überströmwege darstellen. Bei Niedergang des Motorkolbens öffnen sich nahe unterer Kolhentotlage zunächst die mit gleichartigen Kolbenschlitten zusammenarbeitenden Zylinderschlitze io und p, wodurch Spülluft -oder verdünnte Ladung, wie sW sich gerade im Vorkompressionsraum des Motors befinden mag, durch Spülschlitz h in den Verbrennungsraum überführt wird, während die Hauptladungsluft etwas später durch die gleichfalls mit entsprechenden Kolbenschlitzen zusammenarbeitenden Zylinderschlitzee und b in den Verbrennungsraum überführt wird, nachdem sie aus der nach Patent 422 393 im Überströmkanal des Zylinders angeordneten Ejektordüse sich mit Brennstoff angereichert hat.Two-stroke engine There are four- and two-stroke internal combustion engines known at which each load to be introduced a quantum of scavenging air into the combustion chamber is sent in advance for the purpose of flushing out the exhaust gases and preventing the mixture deterioration by being a part. the residual exhaust gas mixes with the fresh mixture. The invention relates to an application of this device to the subject matter of patent 422 393. Fig. I shows an exemplary schematic longitudinal section through a such a prime mover, while Figs. 2 and 3 show sections through the overflow paths represent. When the engine piston descends, the lower piston dead position opens first of all the cylinder slots that work together with piston slides of the same type io and p, which means scavenging air or a diluted charge, such as sW in the pre-compression space of the engine, is transferred through the scavenging slot h into the combustion chamber, while the main charge air a little later through the likewise with corresponding Piston slots cooperating cylinder slots e and b into the combustion chamber is transferred after it from the patent 422 393 in the overflow channel of the cylinder arranged ejector nozzle has been enriched with fuel.
