VARIABLE VALVE TIMING CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

Title:

VARIABLE VALVE TIMING CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

Document Type and Number:

WIPO Patent Application WO/2013/133379

Kind Code:

A1

Abstract:

Intermediate position feedback control is performed when the valve timing of an intake valve is at an intermediate lock position, an intermediate lock is required, and the engine rotation speed is greater than a first engine rotation speed (R1). Furthermore, forced lock control is performed when the valve timing of an intake valve is at an intermediate lock position, an intermediate lock is required, the engine rotation speed is less than the first engine rotation speed (R1), and intermediate position feedback control is not being performed. As a result, it is possible to maintain the valve timing at the intermediate lock position, even if the engine rotation speed increases when the valve timing needs to be in the intermediate lock position.
