Description

Crankshaft, internal combustion engine, and control device Background A four-stroke internal combustion engine having a V-configuration of 20 cylinders is known from document WO2018/138007 A1. Disclosure of Invention The invention relates to a crankshaft having ten crankshaft cranks, wherein the crankshaft cranks are numbered consecutively in ascending order from K1 to K10 along the longitudinal extension of the crankshaft starting from the clutch side, and wherein the crankshaft cranks are arranged offset in the angular position, so that a so-called crank pattern is formed. The crank shaft has one of the following sequences K1, K9, K6, K3, K4, K10, K2, K5, K8, K7 or K1, K7, K8, K5, K2, K10, K4, K3, K6, K9 in the crank arrangement, viewed clockwise from the clutch side. By means of a suitable ignition sequence, the crankshaft achieves a reduced five-step vibration excitation during operation of a four-stroke internal combustion engine having a V-configuration of 20 cylinders. The crank layout can be circularly symmetric about the longitudinal axis of the crankshaft. That is, the crank pattern can be mapped onto itself by rotation about the longitudinal axis. The crank arrangement can for example have a constant angular degree of 36 °. Thus producing advantageous dynamics during operation. There may be a +/-4 deg. deviation from the ideal 36 deg. angle in crank position. The crank shaft is arranged non-mirror symmetrically with respect to a center plane oriented perpendicular to the longitudinal axis. With a suitable ignition sequence, this results in a reduced fifth-order vibration excitation when a four-stroke internal combustion engine having a V-configuration of 20 cylinders is operated.
