VARIABLE VALVE TIMING CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Title:

VARIABLE VALVE TIMING CONTROL DEVICE OF INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2013/129110

Kind Code:

A1

Abstract:

When an intermediate lock by intermediate lock mechanisms (34a, 34b) is released, the valve timing of an intake valve is controlled to be in advance of an intermediate lock position, and a lock key (35b) for restricting movement in the opposite direction of which the valve timing of the intake valve is controlled is pulled out from an engaging concavity (38b). The valve timing of the intake valve is then controlled to be delayed after the intermediate lock position, and a lock key (35a) is pulled out from an engaging concavity (38a). The intermediate lock by the intermediate lock mechanisms (34a, 34b) is thereby released in a manner such that the lock keys (35a, 35b) are not pushed into the engaging concavities (38a, 38b).
