Generally, it is divided into two ways: hydraulic and mechanical, which can automatically adjust the tension of timing belt and timing chain. Driven by the timing belt or chain, the camshaft drives the valve to open and close in time, and cooperates with the piston to complete the four processes of air intake, compression, work and exhaust.
Tensioner is a common clamping device in belt and chain transmission system, which is characterized by maintaining proper tension between belt and chain during transmission to avoid belt slipping or synchronous belt jumping. Or prevent the chain from loosening and falling off, and reduce the wear of sprocket and chain. Million car purchase subsidy
