Abstract
The line control arrangement includes a valve timing controller generating a predetermined valve timing variable control signal according to an engine speed of a vehicle; and an oil controlling driver generating a rotational force in a predetermined direction according to the valve timing variable control signal received from the valve timing controller to form a corresponding advance line and a corresponding retard line. The line control arrangement for a continuously variable valve timing system reduces noise generated by operation of an oil controlling driver.
Claims18
A line control arrangement for a continuously variable valve timing system of a vehicle, comprising:
- a valve timing controller configured to generate a valve timing variable control signal according to an engine speed of the vehicle;
- and
- an oil controlling driver configured to generate a rotational force in a according to the valve timing variable control signal received from the valve timing controller to form a corresponding advance line and a corresponding retard line.
A line control arrangement for a continuously variable valve timing system of a vehicle, comprising:
- a housing;
- an oil supply shaft rotatably mounted within said housing;
- a motor configured to rotate said oil supply shaft to an advance position or a retard position based on a valve timing variable control signal received from a valve timing controller;
- an advance passageway formed through said housing when said oil supply shaft is in said advance position, said advance passageway fluidly coupling an oil supply hole to an advance hole.
- a retard passageway formed through said housing when said oil supply shaft is in said retard position, said retard passageway fluidly coupling an oil supply hole and a retard hole.
A method for controlling a continuously variable valve timing system of a vehicle, comprising:
- measuring a engine speed of a vehicle;
- generating a valve timing control signal;
- transmitting the valve timing control signal to a motor coupled to a oil supply shaft;
- rotating said oil supply shaft to an advance position to form an advance passageway coupling an oil supply hole to an advance hole;
- allowing fluid to flow through said advance passageway into an advance chamber of a vane housing;
- and
- moving a vane within the vane housing to alter valve timing.
