14 Volkswagen Bora camshaft electromagnetic regulating valve is installed on the camshaft chamber, which is a part of the engine oil circuit. According to the control signal of ECU, the solenoid valve guides the oil to the corresponding channel of camshaft blade adjuster according to the adjustment requirements, and the rotor in the blade adjuster rotates forward or backward according to the oil pressure, thus achieving the purpose of adjusting the timing.

Introduction of camshaft regulating valve

OVC valve is a solenoid valve used to adjust the opening and closing time of the valve, which can advance or delay the intake time.

By adjusting the phase of the engine cam, the opening and closing time of the valve changes with the engine speed, which can improve the combustion efficiency of combustible gas in the cylinder and increase the engine power, and then make the engine work in an ideal state.

Disassembly and assembly steps of camshaft solenoid valve
