What domestic vehicles use selenoid to actuate the intake and exhaust valves?

Domestic vehicles that utilize solenoids to actuate intake and exhaust valves typically feature variable valve timing (VVT) systems. Examples include certain models from manufacturers like Ford, General Motors, and Honda, which may employ solenoid-controlled mechanisms for improved engine performance and efficiency. These solenoids allow for precise timing adjustments of the valves, enhancing power delivery and fuel economy. Notably, the Ford EcoBoost engines and GM’s Ecotec engines often incorporate such technology.
