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.
