Description

"Rotationskolben-Brennkraftmaschine mit Fremdzündung durch eine Zündkerze" Die Erfindung bezieht sich auf eine Rotationskolben-Brennkraftmaschine mit Fremdztindung durch eine ZUndkerze, insbesondere in Trochoidenbauart, die im wesentlichen aus einem Gehäusemantel und aus einem in diesem umlaufenden Kolben besteht. "Rotary piston internal combustion engine with spark ignition by a spark plug" The invention relates to a rotary piston internal combustion engine with external ignition by a spark plug, in particular of the trochoid design, which essentially consists of a housing jacket and a piston rotating in this.

Der Startvorgang oder der Kaltstart bei einer Rotationskolben-Brennkraftmaschine unterliegt ungunstigen Bedingungen. Sondereinrichtungen in Form einer DoppelzUndung wirken sich unvorteilhaft auf die Standfestigkeit der Kerzen und der Dichtleisten sowie auf die Gleitbahnen aus. Außerdem kann bei der Doppelzündung durch schlagartige Druckzunahme ein Klopfen ausgelöst werden.The starting process or the cold start in a rotary piston internal combustion engine subject to unfavorable conditions. Special devices in the form of a double ignition have an unfavorable effect on the stability of the candles and the sealing strips as well as on the slideways. In addition, when double ignition can occur suddenly If the pressure increases, a knock can be triggered.

Um all diese Mängel zu beseitigen, liegt der Erfindung die Aufgabe zugrunde, eine möglichst einfache und weniger aufwendige Einrichtung zu schaffen, die Störungen oder Frühzündungen beim Betriebsablauf eines Kaltstartes vermeidet.It is an object of the invention to remedy all of these shortcomings based on creating a facility that is as simple and less complex as possible, which avoids malfunctions or premature ignition during a cold start.

Die gestellte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß mit Bezug auf die Umlaufrichtung des Kolbens am Gehäusemantel eine Glühkerze hinter der ZUndkerze angeordnet ist.The object set is achieved according to the invention in that with reference to the direction of rotation of the piston on the housing jacket a glow plug behind the spark plug is arranged.

In vorteilhafter Ausgestaltung der Erfindung kann die Glühkerze 30° bis 60° nach der kleinen Achse vorgesehen sein.In an advantageous embodiment of the invention, the glow plug can be 30 ° up to 60 ° after the minor axis.

Um den schädlichen Raum zu verkleinern, kann aufgrund der Erfindung die Glühkerzenbohrung mit einem Drehschieber versehen sein.In order to reduce the harmful space, can due to the invention the glow plug bore can be provided with a rotary valve.

In der Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt.In the drawing is an embodiment of the subject matter of Invention shown.

Die Rotationskolben-Brennkraftmaschine besteht aus einem Gehäusemantel 1, in dem an der zweibogigen Mantellaufbahn 2 der in Pfeilrichtung 3 umlaufende dreieokige Rotationekolben 4 mit seinen Dichtleisten 5 gleitet.The rotary piston internal combustion engine consists of a housing jacket 1, in which on the two-arched jacket track 2 in the direction of arrow 3 circumferential Dreieokige rotary piston 4 with its sealing strips 5 slides.

Im Gehäusemantel 1 vor der kurzen Achse 6 gegenüber dem Einlaßkanal 7 sind der ZUndkanal 8 mit der ZUndkerze 9 und gegenüber dem Auslaßkanal 10 und diagonal sum Einlaßkanal 7 bei einem Winkel von 300 bis 600 nach der kurzen Achse 6 eine in einer Glahkerzenbohrung 11 liegende Gltlhkerae 12 radial zur Exzenterwelle 13 angeordnet.In the housing jacket 1 in front of the short axis 6 opposite the inlet channel 7 are the ignition channel 8 with the ignition plug 9 and opposite the outlet channel 10 and diagonal to the inlet channel 7 at an angle of 300 to 600 on the short axis 6 a glow plug 12 lying in a glazing candle bore 11 radially to the eccentric shaft 13 arranged.

Die Glühkerzenbohrung 11 kann beispielsweise mit einem Drehsohieber versehen sein, der nah an der Mantellaufbahn 2 angeordnet ist und zur Verkleinerung des schädlichen Raumes bei ausgeschalteter Glühkerze während des Betriebszustandes des Motors nach der Kaltstarthilfe dient.The glow plug bore 11 can, for example, with a rotary valve be provided, which is arranged close to the jacket track 2 and to reduce the size the harmful space when the glow plug is switched off during operation of the engine after the cold start aid.
