When the OCV is in the OFF position, the switching 
piston does not operate because the switching oil 
pressure within the intake rocker shaft is below the 
specified pressure, and so the wing of the high 
speed rocker arm does not reach the switching pis-
ton. Accordingly, the intake valve is driven by the low 
speed rocker arm.

When the OCV is in the ON position, the switching 
piston is increased by the oil pressure because the 
switching oil pressure within the intake rocker shaft is 
above the specified pressure, and so the wing of the 
high speed rocker arm reaches the switching piston. 
Accordingly, the intake valve is driven by the high 
speed rocker arm.

TIMING BELT

The timing belt is designed to reduce friction and 
weight by narrower width of the timing belt. The 
weight reduction is due to the profile change of the 
each component related to the timing belt.

TIMING BELT COVER

Uniting the crank angle sensor harness with the tim-
ing belt cover reduces installation time and prevents 
interference with the drive belt or timing belt.
