Abstract

An internal combustion engine as described with a zero degree angle formed by the cylinders in which the pistons actuate various cranks of a crankshaft, the bends of which are offset at an angle in relation to one another in such a way that there is a total matching of the second-order inertial forces. The angle of offset alpha between the two cranks is 270 degrees. In a further development of the invention, two such internal combustion engines can be arranged in series to form a four-cylinder internal combustion engine. The drawing of figure 1 shows the axes of the first and second cylinders denoted as (1) and (2), which lie in one and the same plane. The pistons (3 and 4) actuate via connecting rods (5 and 6) the cranks (7 and 8) of a crankshaft, the axis of which is denoted by 9. The angle between the bends of the cranks (7 and 8) is denoted by alpha and is 270 degrees. The arrow (10) shows the direction of rotation of the crankshaft. Figure 2 shows a diagram of the second-order forces of inertia (P) of the first and second cylinders for the corresponding crank positions phi and their counterbalancing.

Description

Diese Formel ist nicht anwendbar für Zylinderwinkel von größer als 90° bis kleiner k als 180°. Sie läßt somit auch keine flachbauenden ') Brennkraftmaschinen zu. Die Massenkräfte 2. Ordnung sind durch eine Welle auszugleichen.An internal combustion engine in V-design is known from laid-open specification 58-113646 Japan - in which the angle θ enclosed by the cylinders is less than 90 ° and the angle of the crank throws is TT- 2 θ , which is directed opposite to the cylinder angle. This formula is not applicable to cylinder angle of greater than 90 ° to less than 180 ° k. It therefore allows no flat construction ') internal combustion engines. The second order inertia forces are to be balanced by a wave.
