Tomei - Bery Ring
The function of which valve sheet
is asked, is maintaining air tightness
with a valve, and generally wear resistance
is required. However, with the engine
used by high rotation and high load,
the cooling performance of a valve
sheet becomes very important further,
and it is greatly concerned with an
engine output. When engine is high
rotation and high load, it is impossible
to achieve high output from the engine
if cooling performance of the cylinder
is low and knock limit does not become
high, since the temperature of the
circumference of a cylinder head rises
unusually. In racing engine that temperature
needed to be carefully controlled,
how much you can cool the circumference
of the sheet ring is the important
issue, and the technique of using
high heat conduction metal, such as
copper for a sheet ring, has been
taken. Copper has one of the highest
thermal conductivities through all
metal that enables receiving heat
from cylinder and cool it down quickly
by transmit the heat to the cylinder
head. (Degree of heat conduction:
1.silver, 2.copper, 3.gold, 4.aluminium,
... 10. cast iron - STD). We select
beryllium copper alloy (BeCu) that
can secure mechanical intensity most
in the copper alloy, which has ideal
fatigue resistance and wear resistance
while securing a preeminent cylinder
cooling performance. We named it "bery-ring"
and applied to the high performance
turbo charged engine. of market share
in the world with beryllium copper
so that we can offer this super-high
grade material beryllium in affordable
price.
