reason for intake and exhaust polished MB Star C3 modified the largest intention
is to improve the original manifold and cylinder prime parts, reduce the
production costs of the relationship can not be carried out subsequent
processing procedures, leading to the internal wall surface is too
rough, affecting air flow smooth
through the formalities, can accelerate the air flow intake and exhaust
by hand polishing process, however, sometimes because of the skill and
technique, but a problem of the effect of high and low drop
considerably, first of all the most commonly encountered problem is construction range limit.
Other
than the type of tools that are used in conventional polishing as small
drills pneumatic throwing knife mainly due to their functional
limitations, so although within the cylinder head into the exhaust
passage subjected to surface polishing, but the face of the length and
depth of the intake manifold but
could not be implemented, it can only export position of its engagement
with the engine grinding to increase the project, its diameter is fully
engaged (with the cylinder head inlet manifold diameter is usually
Ford Ids Vcm
smaller in the original specifications), to reduce air opportunity resistance, which is one drawback. And
even if only the airway grinding cylinder head, but for the
construction of the internal "valve guide surface is also a tradition of
throwing knife, which is huge position to affect the air flow, which is
the second drawback.
Generally
commercially available vehicles of the top surface of the combustion
chamber usually is rough Only High performance car engines may have to
be more cost-grinding, to present a smooth surface.
In
addition, throughout the construction process are using handheld
throwing knife, wrist force toilet directly affect throwing knife
grinding depth on the wall, helpless to force non-machine-like stability
in your hands, plus the entire polishing working hours mostly up to a
few days construction
standards of good and bad human factors that affect many, how much
lower modification effect, while it is also the majority most often
ignored shortcomings. To
solve these problems, currently has stores introduction designed to
polished professional machine, named Extrudehone polishing grinder,
converted from the old shop - grid Litas introduced this machine and
traditional polishing tools GM Tech 2 in the construction process ,
the largest difference, the first is the use of the abrasive material,
most of the latter is fixed to the leaf-shaped sandpaper, and the former
is used to fluidize the abrasive grit polishing of the wall, this
intron emery, resins, etc. the composite abrasive grit, dark gray appearance, touch soft object with liquidity, the overall look is a bit like lava.
