| 摘要 |
A variable valve timing control unit includes an intake-side variable valve timing control apparatus (A), an exhaust-side variable valve timing control apparatus (B), an intake-side phase control valve (41) selectively performing supply and discharge of fluid relative to an advanced angle fluid passage (34) and a retarded angle fluid passage (35) of the intake-side variable valve timing control apparatus, an exhaust-side phase control valve (42) selectively performing supply and discharge of the fluid relative to an advanced angle fluid passage and a retarded angle fluid passage of the exhaust-side variable valve timing control apparatus, and a single lock control valve (43) controlling supply and discharge of the fluid relative to unlock fluid passages (36) of the respective intake-side variable valve timing control apparatus and the exhaust-side variable valve timing control apparatus. |
