Variable Valve Timing Solenoids

VVT solenoid controls the left and right movement of the slide valve according to the duty cycle signal provided by the engine ECU, so as to control the direction of the oil passage to the camshaft. If the outflow direction of engine oil is the same as the rotation direction of the camshaft timing gear, the valve opening time is advanced. If not, the time of valve opening is delayed.

MAPMS's variable timing valve solenoid can adjust the amount of intake or exhaust, valve opening and closing time and angle according to the operation of the engine. Optimize the amount of air entering and improve variable valve timing system combustion efficiency.
