Valve timing controller for use with internal combustion engine |
摘要 |
An internal combustion engine is equipped with a valve timing controller capable of minimizing the electric power consumption and frictional wear of elements. The valve timing controller can vary the valve timing of valves. A camshaft is moved axially forwardly or rearwardly by electrically energizing an outer solenoid clutch or a brake releasing solenoid, respectively. An axial movement of the camshaft results in a change in valve timing. With the exception of a transient period during which the valve timing is being varied, both the brake releasing solenoid and the outer clutch are electrically deenergized to thereby reduce the electric power consumption, and both of them are maintained out of contact with a displaceable disc 13 to thereby reduce frictional wear thereof.
