ABSTRACT:
An internal combustion engine with two rows of cylinders with a V-angle of 180 degrees has a crankshaft provided with a flywheel, said crankshaft having a drive for a parallel intermediate shaft adjacent to the flywheel. One camshaft of each row of cylinders is driven respectively from the two ends of this intermediate shaft. The arrangement of the drive for the intermediate shaft near the flywheel avoids the transmission of rotary oscillations from the crankshaft to the intermediate shaft.
