Abstract:
Governor of the stroke, in internal combustion engines (10) of the stroke between camshafts (13), (14) and crankshaft (12) connected by a continuous belt (20) or chain, to compensate for any effects of wear, assembly errors, stresses due to movement and other factors and, when running speed changes, to set optimum timing values for each speed, comprising actuators (43), (44), operated by an electronic drive unit (50), that determines the variation in length of sections (30), (31) of the belt (20) between the crankshaft (12) and the camshafts (13), (14) and between the latter two, while an automatic belt tightener (21) maintains the tension of the belt (20) constant from one moment to the next.
