Abstract

A method of gas distribution in a four-stroke internal combustion engine with phase regulation and a device for its implementation are intended for ensuring optimal phases of gas distribution under all speed working conditions of the engine and thus increasing its power-economic and dynamic characteristics. The phase regulation is effected by means of angular shift of the cam shafts (1, 2) in relation to the crankshaft (10), whereas in case of increase of rotation speed one camshaft (1) is shifted in the direction of its rotation and the other camshaft (2) against the direction of its rotation. A mechanism for gas distribution in a four-stroke internal combustion engine with phase regulation comprises two camshafts (1, 2) controlling the inlet (3, 4) and outlet (5, 6) valves by means of cams, and further comprises a device for angular shifting of the camshafts (1, 2) in relation to the crankshaft (10) by means of influencing a driving-element (7) with actuating mechanisms (15, 16) interconnected through a control unit (14) and provided with rollers (11, 12).
