TIMING CHAIN, CHAIN TENSIONER [SKYACTIV-D 1.5]
id0110q2001500
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 located between the camshaft sprocket and crankshaft sprocket.
• The lubrication of the timing chain and each sprocket is performed by the engine oil supplied from the cylinder block.

Chain tensioner
• The chain tensioner is located on the cylinder block (engine front part).
• An oil pressure type chain tensioner has been adopted for the chain tensioner.
OPERATION
Chain tensioner
• Tension fluctuation on the timing chain is suppressed by hydraulic pressure and tension is held constant by spring force.
