Abstract

The ic engine is operated by disconnecting working cylinder alternately. The engine can be reciprocating or totating pistons and may be used in marine propulsion engines when they run an idling speeds. The cyclic disconnection of cylinders ensures that smaller gear drives can be used, because the engine itself widens the partial load running range. The cyclic disconnection system can be used for four or two strokes engines, with the cylinders electronically connected and disconnected. Compensation of inertia is ensured by a secondary shaft. The working cycle is interrupted in the individual cylinders by disconnection of the ignition and injection process.

Graf v. Seherr-Thoss Verfahren zum abwechselnden Ausschalten von Arbeitszylindern bei Verbrennungsmaschinen 1)ie Erfindung betrifft ein Verfahren zum abwechselnden Ausschalten von Arbeitszylindern bei Verbrennungsmaschinen mit hin- und hergehenden sowie rotierenden Kolben.Count v. Seherr-Thoss procedure for the alternating deactivation of working cylinders in internal combustion engines 1) he invention relates to a method for alternating Switching off working cylinders in internal combustion engines with reciprocating as well as rotating pistons.

bei Schiffsmaschinen kommt es oft vor, dass sie in unwirtschaftlichen Teillastbereichen fahren müssen, z.B. in Häfen oder Kanälen bei Leerbetrieb. Man kann ein grösseres Getriebe sparen, indem man den Teillastbereich der maschine selbst durch Ausschalten einzelner Arbeitszylinder erhöht. Bei grösseren Maschinenanlagen kann man auch Hilfsantriebmaschinen sparen.in the case of marine engines, it often happens that they are in uneconomical Have to drive part-load areas, e.g. in ports or canals when empty. Man a larger gearbox can save by using the partial load range of the machine itself increased by switching off individual working cylinders. For larger machine systems one can also save auxiliary drive machines.

L'ekaiint sind Verbrennungsmaschinen, bei denen zu ihrer rl'eilbelastung der Arbeitsprozess einzelner oder mehrerer Zylinder vorübergehend abgeschaltet werden kann. ekannt ist ferner, dass bei Kolben-Verbrennungsmaschinen mit garden Zylinderzahlen ganze Gruppen von ylindern abgeschaltet werden können.L'ekaiint are internal combustion engines, in which to their rl'eil load the working process of one or more cylinders can be temporarily switched off can. It is also known that piston internal combustion engines with garden cylinder numbers Whole groups of people can be turned off.

Gegenstand der brfitldung ist das beschalten von Zylindern bei geraden und ungeraden Gesamt-Zylinderzahlen in Reihen- oder in V-Bauweise.The subject of the training is the wiring of cylinders for straight lines and uneven total number of cylinders in in-line or V-design.

Ein Ausführungsbeispiel der erfindung ist zeichnerisch mit einer Fünfzylindermaschine dargestellt. Abb. 1 zeigt den Kurb eltrie b e iner Viertakt-Fünfzylinder-maschine und ihrer b ekannten Arbeitsfolge, Abb. 2 analog eine Zweitakt-Fünfzylinder-maschine. Das Abschalten des Arbeitsvorgangs in den einzelnen zylindern findet in der Weise statt, dass Zündung und Einspritzvorgang laufend elektronisch ab- und eingeschaltet werden, nach der 'i'abelle Abb. 3 für Viertaktmaschinen, Abb. 4 für Zweitaktmaschinen. Die Abbildungen 5 und 6 geben die Ziindfolge bei zwei Möglichkeiten für abzuschaltende Zylinder von Vier- und Zweitaktmaschinen wieder. Durch dieses rotierende Ausschaltverfahren lt. Erfindung werden alle Zylinder bzw.One embodiment of the invention is shown in the drawing with a five-cylinder engine shown. Fig. 1 shows the crank drive of a four-stroke five-cylinder machine and its known work sequence, Fig. 2, is analogous to a two-stroke five-cylinder machine. The shutdown of the work process in the individual cylinders takes place in this way instead of the ignition and the injection process being continuously switched on and off electronically according to the 'i' table Fig. 3 for four-stroke machines, Fig. 4 for two-stroke machines. Figures 5 and 6 show the ignition sequence for two options for switching off Cylinders of four- and two-stroke engines again. Through this rotating shutdown procedure According to the invention, all cylinders or
