1.Dynamic Valve Timing Coordinated Adjustment

Linked with the engine’s ECU (Electronic Control Unit), this gear can receive real-time operating condition signals (such as speed, load, and water temperature) and adjust the relative phase between the camshaft and crankshaft through its built-in hydraulic structure:

·At low speeds: It retards the closing of the intake valves and uses airflow inertia to supplement air intake volume, preventing insufficient power.

At high speeds: It advances the opening of the intake valves, optimizes the intake-exhaust overlap angle, and accelerates exhaust gas discharge to improve intake efficiency.

·Meanwhile, as a "power transmission bridge" in the timing system, it can accurately transmit the rotational power of the crankshaft to the camshaft, ensuring that the valve opening/closing timing is fully synchronized with the piston movement rhythm and avoiding mechanical interference.

2. Resolving Typical Engine Fault Hidden Risks

Aiming at the common "rattling noise during cold start" issue of the Mercedes-Benz 276 engine (mostly caused by phase adjustment jamming due to wear of the original timing gear), this gear effectively eliminates mechanical impact noise during cold starts by optimizing the tooth surface meshing accuracy and hydraulic response speed. Additionally, its structural design is adapted to the pressure characteristics of the 276 engine’s intake system, which can reduce the fluctuation of intake manifold pressure caused by timing deviations, lower the incidence of faults such as unstable idling and acceleration lag, and ensure stable engine operation.
