Idler wheel rocker arm is adopted

in the rocker arm so as to reduce

the abrasion between camshaft cam

and rocker arm

Camshaft is made of spheroidal graphite

iron, of 5-point bearing and no special

bearing.

The

valve

spring

is

non-isometry

structure,

which

may

prevent

sympathetic vibration and

rupture. Please notice

that

the

color-marked

should be upwards and the

larger-distant is upwards.

Spring

section

is

elliptoid, which surface

is shot blasting processed

to

improve

fatigue

resistance.

Valve

Inlet valve is 1.00/limit is 0.5mm

Exhaust valve is 1.2mm/limit is 0.7mm

Valve seat

Working

surface

width

0.9-1.3mm

The valve is of umbrella

structure.

The

intake

valve is similar to the

exhaust valve, but the size

of the former is a little

bigger than the later. Each

cylinder is of four-valve

structure,

which

may

improve

emission

efficiency,

decrease

weight

and

inertia

resistance and extend the

life time of valve and

valve seat. Besides it, it

is of benefit for spark

plug allocation, which

improve burning efficiency

and

reduce

injurant

emission

and

fuel

consumption.

Valve oil seal is of

steel-shelf

and

rubber-ring-spring

tension structure. The

Please note that align the marks of camshaft

belt gear and valve cover, the marks of

crankshaft timing belt gear and front end cover

and the marks of oil pump belt gear and front

end cover when installing timing belt. (The

60mm-length screw drive must be inserted into

the lower balance test hole, otherwise turn

around oil pump belt gear and then align timing

mark.)

Please align the marks of

drive/driven gears when installing

oil pump gears as shown.
