TIMING CHAIN, CHAIN TENSIONER [WITHOUT CYLINDER DEACTIVATION (SKYACTIV-G 2.0, SKYACTIV-G 2.5)]


id0110m1001500


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 (front of engine).
•  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.
