Mazda CX-5 Service & Repair Manual: Timing Chain, Chain Tensioner
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.

Ebd Control
Outline
EBD control uses the ABS system to control brake fluid pressure distribution
to the rear wheels so that they do not lock-up prior to the front wheels during
braking, thereby preventing the loss of handling stability.
Feature
EBD control has independent control syste ...
Rollover Valve
Purpose, Function
Prevents fuel from flowing into the evaporative gas passage during sudden
cornering or vehicle rollover.
Construction
The rollover valve is built into the fuel tank.
