ABSTRACT:
A positive engagement clutch between the serially connected coaxial first and second crankshafts in an internal combustion engine is activated upon acceleration of the second crankshaft to the speed of the first crankshaft and after the second crankshaft assumes a predetermined angular position relative to the first crankshaft. The acceleration is performed by a friction clutch which is interposed between first and second camshafts which are respectively driven by and drive the first and second crankshafts. The first crankshaft and the associated camshaft form part of a normally operative first section of the engine wherein the first crankshaft is rotatable by one or more cylinders whenever the engine is running. The second crankshaft and the associated second camshaft form part of a second section of the engine wherein the crankshaft is rotatable by one or more additional cylinders upon direct coupling of the two crankshafts to each other. Each section of the engine may be installed in a discrete cylinder block or both sections may have a common casing.
