Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Um bei Zweitaktmaschinen, bei welchen die frische Luft durch ein Ventil eingelassen und der Auspuff durch den Kolben gesteuert wird, verschiedene Verdichtungsgrade zu erreichen, wird statt eines besonderen Luftauslaßventils, welches die überschüssige Luft ins Freie entweichen läßt, das Lufteinlaßventil / derart gesteuert, daß es noch eine bestimmte Zeit offen bleibt, wenn der Kolben k In order to achieve different degrees of compression in two-stroke engines, in which the fresh air is let in through a valve and the exhaust is controlled by the piston, instead of a special air outlet valve which allows the excess air to escape into the open, the air inlet valve / is controlled in such a way that it remains open for a certain time when the piston k

ίο die Auspuffkanäle α bereits verschlossen hat (Fig. i).ίο the exhaust ducts α has already closed (Fig. i).

Von der in den Arbeitszylinder durch Ventil / eingeführten frischen Luft strömt dann — nach Abschluß der Auspuffkanäle a — der etwa überschüssige Teil mit langsam ansteigender Verdichtung (nach der Verdichtungslinie c, Fig. 2) in die Druckleitung der Luftpumpe zurück. Je nachdem nun das Ventil / in IV, V oder VI geschlossen wird, wird der Verdichtungsgrad entsprechend verändert; die verschiedenen Verdichtungslinien sind durch IV1, V1 und VI1 dargestellt.Of the fresh air introduced into the working cylinder through valve / then flows back into the pressure line of the air pump - after the exhaust ducts a has been closed - the excess part with slowly increasing compression (according to compression line c, FIG. 2). Depending on whether the valve IV, V or VI is closed, the degree of compression is changed accordingly; the various compression lines are represented by IV 1 , V 1 and VI 1 .

Nach Schluß des Ventiles / wird der gasförmige oder flüssige Brennstoff durch Ventil b eingeführt. ,After closing the valve / the gaseous or liquid fuel is introduced through valve b . ,

Claims (1)

Patent-Anspruch :Patent claim: Regelungsverfahren für Zweitaktexplosionskraftmaschinen, dadurch gekennzeichnet, daß zur Erzielung verschiedener Verdichtungsgrade das Luftventil nach Abschluß der Auspuffkanäle durch den steuernden Kolben noch längere oder kürzere Zeit offen bleibt, damit die Luft aus dem Arbeitszylinder in die Druckleitung der Luftpumpe zurückströmen kann.Control method for two-stroke explosion engines, characterized in that that to achieve different degrees of compression the air valve after completion of the exhaust ducts through the controlling piston remains open for a longer or shorter time so that the air can be released can flow back from the working cylinder into the pressure line of the air pump. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
