Abstract
Method and device for regulating the phase angle between a first and a second crankshaft of an internal combustion engine. The engine includes primary cylinders that communicate with secondary cylinders and in every primary cylinder there is movably arranged a primary piston that is connected to the first crankshaft and in every secondary cylinder there is movably arranged a secondary piston that is connected to the second crankshaft. The first and second crankshafts are connected to each other by means of a transmission adapted with the device that includes a crankshaft extension for obtaining the control of the phase angle, the extension being fixed against rotation and displaceably connected to one of the crankshafts and via a grooved portion rotationally connected to the second of the crankshafts. When the crankshaft extension in displaced, rotation is obtained in the grooved portion that results in a corresponding phase angle shift.
