Does the Chery 484 engine VVT pulley need timing alignment?

[MarleyLee]

Chery 484 engine VVT pulley requires timing alignment. Issues with the VVT timing pulley may cause timing belt skipping, leading to symptoms such as unstable idle speed and poor acceleration in the engine. Nature of VVT: The technology employed in VVT engines, namely Continuous Variable Valve Timing technology, can continuously adjust the engine's valve opening/closing timing and air intake volume, thereby improving engine power, optimizing torque curves, and reducing fuel consumption. Working principle of VVT: The working principle of VVT is that the crankshaft drives the camshaft through timing belts, gears, or chains. The profile and position of camshaft lobes are typically optimized for specific engine speeds, which usually reduces torque at low RPM and power at high RPM. VVT technology enables adjustments based on engine operating conditions, enhancing engine efficiency and power output.
