Gates Engine Variable Valve Timing (VVT) Solenoids regulate pressurized engine oil flowing to the camshaft actuator, allowing the engine’s control system to advance or retard camshaft timing as operating conditions change. Also known as oil control valves, these components help maintain proper valve timing for smooth idle, responsive engine performance, fuel efficiency, and emissions control. Gates designs its VVT solenoids to original-equipment specifications for fit, form, and performance, with durable construction and testing for oil flow, pressure, electrical resistance, and leakage to support dependable operation.
