VALVE TIMING CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

PROBLEM TO BE SOLVED: To promptly and certainly start an internal combustion engine even if an assembling angle of a driving rotary member and a follower rotary member suitable for starting the engine is at an angular position shifted from the most-delayed angular position or the most advanced angular position.

SOLUTION: An assembling angle changing means 4 for changing the assembling angle of a driving ring 3 on the side of a crankshaft and a follower shaft member 7 on the side of a camshaft 1 is provided between the driving ring 3 and the follower shaft member 7. The assembling angle changing means 4 is controlled in accordance with the operating state of the internal combustion engine. In such a valve timing control device at the time of cranking the internal combustion engine, the assembling angle changing means 4 is so controlled as to change the assembling angle to the angular position suitable for starting the engine. According to the device, even if the assembling angle of the driving ring 3 and the follower shaft member 7 is shifted from the angular position suitable for starting the engine in such a state that the engine is stopped, it is possible to rapidly modify the assembling angle at the time of cranking.
