ABSTRACT:
In an internal combustion engine with cylinders inline and an overhead camshaft for actuation of the intake and exhaust valves, the camshaft is driven from the crankshaft by means of a driving gear and an intermediate shaft, the driving gear being rigidly connected to an outer cheek of the crankshaft. With this arrangement the distance between the crankshaft bearings remains unchanged and a minimum overall length of the engine is achieved. At the same time a speed reduction gear may be located anywhere between the crankshaft and the camshaft.
