1.Valve Timing Regulation

·As a core camshaft phaser component, it adjusts the camshaft phase in real time based on engine operating conditions (controlled by the Engine Control Module, ECM). By modifying the timing and angle of valve opening/closing, it optimizes intake and exhaust volumes, improving the engine’s power output at high speeds and torque performance at low speeds.

2.Ensuring Precise Valve Distribution

·It works with the timing chain to synchronize the opening/closing of valves with the piston’s reciprocating motion (synchronization accuracy within ±1° crankshaft angle). This is critical for avoiding valve-piston interference, ensuring stable engine operation, and maximizing performance.

3.Optimizing Fuel Economy and Emissions

·By optimizing valve timing, it promotes more complete fuel combustion. This not only reduces fuel consumption (tested to lower high-speed fuel consumption by 5%-8% for M278 engine models) but also minimizes harmful emissions (e.g., reducing nitrogen oxides and hydrocarbons by 10%-12%), meeting Euro VI and other strict emission standards.
