1. Cylinder Head Cover
Lightweight yet high-strength aluminum cylinder head covers are used.
An oil delivery pipe is installed inside the cylinder head cover. This ensures lubrication to the sliding parts
of the roller rocker arm, improving reliability.
2. Cylinder Head Gasket
A steel-laminate type cylinder head gasket is used. A shim is used around the cylinder bore of the gasket to
help enhance sealing performance and durability.

3. Timing Chain and Chain Tensioner
Both the primary and secondary timing chains use roller chains with a pitch of 9.525 mm (0.375 in.).
The timing chain is lubricated by an oil jet.
The primary timing chain uses one chain tensioner, and each of the secondary timing chains for the right
and left banks uses one chain tensioner.
Both the primary and secondary chain tensioners use a spring and oil pressure to maintain proper chain
tension at all times. They suppress noise generated by the timing chains.
The primary chain tensioner is the ratchet type with a non-return mechanism.

LUBRICATION SYSTEM
1. General
The lubrication circuit is fully pressurized and all oil passes through an oil filter.
A cycloid rotor type oil pump is used.

2. Oil Pump
A compact cycloid rotor type oil pump directly driven by the crankshaft is used.
This oil pump has used an internal relief method which circulates relief oil to the suction passage in the
oil pump. This aims to minimize oil level change in the oil pan, reduce friction, and reduce air mixing rate
in the oil.
3. Oil Jet
Oil jets for cooling and lubricating the pistons have been provided in the cylinder block, in the center of
the right and left banks.
These oil jets contain a check valve to prevent oil from being fed when the oil pressure is low. This prevents
the overall oil pressure in the engine from dropping.

2) MRE Type VVT Sensor
The MRE type VVT sensor consists of an MRE, a magnet and a sensor. The direction of the magnetic
field changes due to the different shapes (protruded and non-protruded portions) of the timing rotor,
which passes by the sensor. As a result, the resistance of the MRE changes, and the output voltage to
the ECM changes to Hi or Lo. The ECM detects the camshaft position based on this output voltage.
The differences between the MRE type VVT sensor and the pick-up coil type VVT sensor used on
the conventional models are as follows.
ItemSensor TypeItemMREPick-up Coil
Signal OutputConstant digital output starts from
low engine speeds.Analog output changes with the
engine speed.
Camshaft Position
Detection
Detection is made by comparing
the NE signals with the Hi / Lo
output switch timing due to the
protruded / non-protruded portions
of the timing rotor, or made based
on the number of the input NE
signals during Hi / Lo outputs.
Detection is made by comparing
the NE signals with the change of
waveform that is output when the
protruded portion of the timing
rotor passes.
