TIMING CHAIN, CHAIN TENSIONER [SKYACTIV-G 2.0]

id0110h2001500

Purpose, Function

Timing chain

•  The timing chain transmits the rotation force of the crankshaft to the camshaft to perform the rotation timing of the crankshaft and camshaft.

Chain tensioner

•  The chain tensioner constantly maintains the timing chain tension and the timing chain operation is stabilized.

Construction

Timing chain

•  The timing chain is installed between the camshaft sprocket and crankshaft sprocket.

•  Lubrication of the timing chain and each sprocket is performed using the engine oil from the engine front cover.

•  Improvement of the rigidity of the chain guide and tensioner arm and the stability of the timing chain operation have reduced the sliding resistance.

Chain tensioner

•  The chain tensioner is installed to the cylinder block (engine front).

•  An oil pressure type chain tensioner has been adopted for the chain tensioner.

OPERATION

Chain tensioner

•  Fluctuation in the timing chain tension by oil pressure and spring force is suppressed, and the tension is maintained at a constant.
