Abstract

The invention belongs to the technical field of engine VVT systems and provides an engine oil control valve for an engine VVT system and a control method of the engine oil control valve for the engine VVT system. According to theengine oil control valve for the engine VVT system, a valve core (7) is in clearance fit with a valve sleeve (9), a compression spring (8) is positioned between the end part of the valve sleeve (9) and the valve core (7); and a check valve ring I (4) is fixed between a plug I (3) and the step of a positioning pin (5), a check valve ring II (6) is fixed between the step of the valve core (7) and the step of the positioning pin (5), and the check valve ring II (6) and the check valve ring I (4) are aligned to a second oil passing channel (24) and a third oil passing channel (26). According to theengine oil control valve for the engine VVT system, internal engine oil recycling is achieved, engine oil consumption is reduced, the phase modulation speed under the low-temperature condition can be increased, the torsional vibration of a timing chain system is reduced, the working requirement of the engine VVT system is met, and the overall performance of an engine is improved.

Description

technical field [0001] The invention belongs to the technical field of the engine VVT ​​system, and more specifically relates to an engine VVT ​​system oil control valve, and the invention also relates to a control method for the engine VVT ​​system oil control valve. Background technique [0002] With the continuous improvement of engine thermal efficiency requirements, it is very important to reduce engine friction and reduce fuel consumption. By reducing the oil pressure of the system, the displacement of the oil pump can be reduced, which can reduce fuel consumption and improve thermal efficiency. The VVT ​​system consumes a lot of oil inside the engine. To reduce the oil consumption of the VVT ​​system has become a difficult point for the hydraulic VVT to overcome. VVT systems in the prior art are mainly electric drive and hydraulic drive. And electric drive: The electric VVT system is driven by a motor to reduce the reducer. The reducer shifts the phase angle between ...
