Engine camshaft cylinder head solenoid valve

OE NO.:    31480440 31480441

Applicable vehicle type: For Volvo

The camshaft solenoid valve is an electromagnetic switch device that controls the flow of hydraulic oil to the camshaft phase regulator according to instructions from the engine control module (ECM). Its main functions include:

• Valve timing adjustment: By changing the phase of the camshaft relative to the crankshaft, dynamically adjust the opening and closing time of the intake or exhaust valves.
• Performance optimization: Automatically adjust valve timing under different operating conditions (such as idle, partial load, full load) to improve engine efficiency and power output.
• Emission control: Cooperate to achieve internal EGR (exhaust gas recirculation), reducing NOx emissions.
