Maintains proper tension on the timing chain, preventing it from slipping or skipping.

The timing chain tensioner ensures that the timing chain remains properly tensioned, automatically adjusting as the chain stretches or wears to prevent slippage, misalignment, or failure of the chain-driven engine components.
