VARIABLE VALVE TIMING ACTUATOR

A6E221112111T05

•

The variable valve timing actuator consists of the following: a housing case integrated to the camshaft 
sprocket, a cover, a camshaft integrated rotor, and a stopper pin that retains the rotor and case when the 
engine stops. Also, the rotor has a chip seal that seals the valve timing advance chamber and the valve timing 
retard chamber.

•

The cover and rotor of the variable valve timing 
actuator are notched, and are used as alignment 
marks when inspecting the variable valve timing 
actuator.

OIL CONTROL VALVE (OCV)

A6E221112111T06

•

The oil control valve (OCV) consists of a spool valve that switches the passages for engine oil, a coil that 
moves the spool valve, a plunger, and a return spring.

OUTLINE OF CONSTRUCTION

A6E330201003T01

•

The lubrication system is a forced-fed type that uses a full-flow filter.

•

An environment-friendly oil filter, designed so that only the internal oil filter (rather than entire assemly) need to 
be replaced, has been adopted.
