Multicylinder engine with paired cylinders - has each piston pair acting on common crank pin hinged to connecting rod

摘要

The multi-cylinder piston engine has pistons (6) driving a crankshaft via connecting rods (10,uue. The cylinders (2,4) are arranged in pairs with parallel axes and are side-by-side and symmetrical about the crankshaft. Their pistons (6) act on a common crank pin (8). The connecting rods (10,11) of the piston pair may be separately connected with the common crank pin, or only one connecting rod (10) may be so connected, and may be hinged (10a) to the other connecting rod (11). All cylinders may be contained in a single cylinder block (1a), and there may be a single cylinder head (1b). There may be one common camshaft for all the cylinders.
