Title: Valve timing adjusting device for internal combustion engine
Inventor: TERASAWA MAYU
IPC: F02D13/02
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of the phase fluctuation width of a camshaft without losing responsiveness. SOLUTION: A camshaft moving direction is determined (310) by comparing a target advancing amount (r) to an actual advancing mount (y). When advancing, whether it is in a positive torque area (torque in the direction opposite to rotation is generated) or not is determined (320), and when it is in a negative torque area (torque in the same direction as rotation is generated), a duty ratio having a small amount of oiling and drainage is outputted (340). When delaying, whether it is in the negative torque area or not is determined (350), and when it is in the positive torque area, the duty ratio having a small amount of oiling and draining is outputted.
