ABSTRACT:
An internal combustion engine wherein a first group of cylinders rotates a first crankshaft and a second group of cylinders can rotate a second crankshaft which can be separably coupled to the first crankshaft by an accelerating friction clutch. The clutch permits slippage of a first clutch member which is driven by one of the crankshafts relative to a second clutch member which drives the other crankshaft while the other crankshaft undergoes gradual acceleration to the speed of the one crankshaft. Once the speed of the other crankshaft matches or closely approximates the speed of the one crankshaft, and the other crankshaft assumes a predetermined angular position relative to the one crankshaft, the first clutch member ceases to slip relative to the second clutch member. The accelerating clutch can be interposed between two camshafts one of which is driven by the one crankshaft and the other of which drives the other crankshaft during acceleration of the other crankshaft. The engine is then equipped with a positive-engagement second clutch which is installed between the two crankshafts and is engaged as soon as the other crankshaft rotates at the speed of the one crankshaft and assumes the desired angular position with respect to the one crankshaft.
