This variable cam timing solenoid with proper size and compact design, which is really easy for installation and there is no special need of maintaining. The cam and the hub are molded to be filled with a synthetic resin of the driven rotating member, and the outer edge of the hub is covered with the synthetic resin. Therefore, it is possible to provide a valve operating assembly of such a driven rotary member and a cam, which is light in weight and capable of lubricating the cam and the hub well.
This variable cam timing solenoid can be an ideal facility that plays an important role in high-performance engines. In addition, it adjusts the phase of the engine cam through the equipped control and execution system, so that the valve opening and closing time changes with the change of the engine speed, so as to improve the charging efficiency and increase the engine power. Compared with ordinary machine on the market, our variable cam timing solenoid can advance or lag the intake time to achieve early opening, early closing, or late intake phase. Equipped with excellent design, it facilitates high torque and fuel economy adjustment in all speed ranges, thereby reducing exhaust emissions.
