Description

Die Erfindung betrifft eine Zweizylinder-Viertakt- Brennkraftmaschine mit einem von den Zylindern gebil­ deten Winkel von 0 Grad, bei welcher die Kolben auf verschiedene Kurbeln einer Kurbelwelle arbeiten, deren Kröpfungen um einen Winkel gegeneinander versetzt sind.The invention relates to a two-cylinder four-stroke Internal combustion engine with one of the cylinders angle of 0 degrees at which the pistons open different cranks of a crankshaft work, their cranks offset by an angle are.

Es sind solche Brennkraftmaschinen in Twin-Bauweise bekannt (DE-Zeitschrift Motorrad, 12/1982, Seite 17-25), die als Gleichläufer (Twin mit gleichachsigen Kurbel­ zapfen) und Gegenläufer (mit 180 Grad Kurbelzapfenver­ satz) bezeichnet werden. Der Gleichläufer hat sich ad­ dierende Massenkräfte 1. Ordnung sowie 2. Ordnung. In der Praxis werden die Massenkräfte 1. Ordnung durch zwei Ausgleichswellen - als balancer bezeichnet - ausgegli­ chen, die der Kurbelwelle mit gleicher Drehzahl entge­ gengesetzt umlaufen. Die Massenkräfte 2. Ordnung blei­ ben jedoch in doppelter Höhe bestehen. Der Gegenläufer wird durch eine der Kurbelwelle mit gleicher Drehzahl entgegengesetzt umlaufende Ausgleichswelle ausgegli­ chen. Die Massenkräfte 2. Ordnung bleiben auch hier in zweifacher Höhe bestehen.They are such internal combustion engines with a twin design known (DE magazine Motorrad, 12/1982, pages 17-25), which as a co-rotor (twin with coaxial crank journal) and counter-rotor (with 180 degree crank pin ver sentence). The synchronizer has ad mass forces of 1st order and 2nd order. In In practice, the first order mass forces become two Balance shafts - called balancer - balanced Chen that counter the crankshaft with the same speed circulate around. The 2nd order mass forces remain ben exist in double amount. The counterpart is by a crankshaft with the same speed counter-rotating balance shaft balanced chen. The 2nd order mass forces also remain here exist twice as high.

Ferner ist die DE-PS 3 66 299 bekannt, die zwar eine Zweizylinder-Brennkraftmaschine mit einem von den Zy­ lindern gebildeten Winkel von 0 Grad, bei welcher die Kolben auf verschiedene Kurbeln einer Kurbelwelle ar­ beiten, deren Kröpfungen um einen Versetzungswinkel α = 270 Grad versetzt sind, zeigt und beschreibt. Diese Maschine ist jedoch als Zweitaktmaschine mit doppelt wirkenden Arbeitszylindern ausgebildet, bei der durch diese Zylinderanordnung auf ein Schwungrad verzichtet werden soll.Furthermore, DE-PS 3 66 299 is known which, although a two-cylinder internal combustion engine with an angle of 0 degrees formed by the cylinders, in which the pistons work on various cranks of a crankshaft, the crankings of which are offset by an offset angle α = 270 degrees are offset, shows and describes. However, this machine is designed as a two-stroke machine with double-acting working cylinders, in which a flywheel is to be dispensed with by this cylinder arrangement.

Ein Hinweis, daß durch diese Kurbelanordnung die Massen­ kräfte 2. Ordnung eliminiert werden können, ist dieser zuletzt ermittelten Druckschrift dagegen nicht entnehm­ bar. An indication that the masses are due to this crank arrangement forces of the second order can be eliminated on the other hand, the last document found was not removed bar.  

Der Erfindung liegt die Aufgabe zugrunde, für eine Zwei­ zylinder-Viertakt-Brennkraftmaschine mit einem von den Zylindern gebildeten Winkel von 0 Grad einen Kurbel­ kröpfungswinkel so zu finden, daß ein vollkommener Ausgleich der Massenkräfte 2. Ordnung entsteht.The invention is based, for a two four-stroke cylinder engine with one of the Cylinders formed an angle of 0 degrees a crank to find the crank angle so that a perfect Equalization of 2nd order mass forces occurs.

Diese Aufgabe wird gelöst durch die Merkmale des Haupt­ anspruchs.This task is solved by the characteristics of the main demanding

Brennkraftmaschinen dieser Bauweise haben den Vorteil guter Laufruhe aufgrund der Beseitigung der Massenkräfte 2. Ordnung durch den Kurbelkröpfungswinkel, da erfindungs­ gemäß die Massenkräfte 2. Ordnung des ersten Zylinders denen des zweiten Zylinders in jedem Punkt entgegen­ gesetzt gerichtet sind und sich somit gegenseitig aufheben (s. Diagramm, Fig. 2).Internal combustion engines of this design have the advantage of smooth running due to the elimination of the 2nd order mass forces by the crank angle, since the 2nd order mass forces of the first cylinder are directed opposite to those of the second cylinder in every point and thus cancel each other out (see. Diagram, Fig. 2).

In Weiterbildung der Erfindung wird vorgeschlagen, zwei der hauptanspruchsgemäßen Brennkraftmaschinen paarweise aneinanderzureihen zu einer Vierzylinder-Brennkraft­ maschine.In a further development of the invention, two are proposed of the main claim internal combustion engines in pairs lined up to a four-cylinder internal combustion engine machine.

Die Massenkräfte 1. Ordnung sind durch bekannte Aus­ gleichsmaßnahmen zu beseitigen.The 1st order mass forces are known by Aus eliminate equal measures.

In der Zeichnung ist die Ausführung der Erfindung schematisch dargestellt.In the drawing is the implementation of the invention shown schematically.

In Fig. 1 sind die Achsen des ersten und zweiten Zylin­ ders der Brennkraftmaschine mit 1 und 2 bezeichnet. Sie liegen in einer Ebene. Die Kolben 3 und 4 arbeiten über Pleuel 5 und 6 auf die Kurbeln 7 und 8 einer Kurbelwelle, deren Achse mit 9 bezeichnet ist. Der Winkel zwischen den Kröpfungen der Kurbeln 7 und 8 ist mit α bezeich­ net, er beträgt 270 Grad. Der Pfeil 10 gibt die Dreh­ richtung der Kurbelwelle an.In Fig. 1, the axes of the first and second cylinders of the internal combustion engine are designated 1 and 2 . They are on one level. The pistons 3 and 4 work via connecting rods 5 and 6 on the cranks 7 and 8 of a crankshaft, the axis of which is designated 9 . The angle between the cranks of the cranks 7 and 8 is denoted by α , it is 270 degrees. The arrow 10 indicates the direction of rotation of the crankshaft.

Fig. 2 zeigt ein Diagramm des Verlaufes der Massenkräfte 2. Ordnung des ersten und zweiten Zylinders bei den jewei­ ligen Kurbelstellungen ϕ und ihre gegenseitige Aufhebung. Fig. 2 shows a diagram of the course of the 2nd order mass forces of the first and second cylinders in the respective crank positions ϕ and their mutual cancellation.
