VARIABLE VALVE TIMING (VVT) SOLENOID
The variable valve timing solenoid is a component of the variable valve timing system that manages the oil flow depending on the engine speed and load. A VVT solenoid in good working condition improves performance and fuel efficiency.
HOW DOES A VVT SOLENOID WORK?
- STEP ONE : The VVT solenoid works with oil pressure, using directions from the ECU to alter rotation of the camshaft.
- STEP TWO : The solenoid alters the oil flow in the conduit leading to the camshaft phaser(s).
- STEP THREE : Conduits can be “instructed” to hasten or delay intake valve opening depending on which conduit will be called upon by the solenoid.
- STEP FOUR : Variation of the intake pressure will be used by the powertrain computer to optimize fuel delivery to the combustion chambers.
