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.
Claims8
Internal combustion engine comprising:
- two rows of cylinders,
- a crankshaft provided with a flywheel,
- at least one intermediate shaft being parallel to and driven by the crankshaft through a drive,
- at least one camshaft in a driving connection with the intermediate shaft per row of cylinders, and
- a first driving connection for a camshaft being provided at an end area of the intermediate shaft away from the flywheel and second driving connection for the other camshaft at an end area of the intermediate shaft near the flywheel,
- wherein the drive of the intermediate shaft is located in an end area of the crankshaft bearing the flywheel, and wherein the intermediate shaft extends below the crankshaft in the installed position of the internal combustion engine.
