Product Description
Crankshaft is the parts that change vertical movement of a piston into
rotational movement. It is suffered from explosion load and inertia power, and
the load by bend vibration or torsion vibration.
Full-counter weighted camshaft:
By preparing counter weight on every cylinder, making inertia power balance so
that bent of the crankshaft is suppressed and the vibration and friction is
reduced, while the reliability of bearing is raised.
Two-Route Lubrication:
Two-route oil supply from tow journals secures crankpin an enough amount of oil
supply. Moreover, X shape oil passage enables supplying oil using the
centrifugal force of a crankshaft; reliability of the oil supply at high RPM is
improved. Furthermore, and resistance of oil flow is reduced by giving a
modification on oil hole exit.
Balance Rate:
Counter weight has its original shape that is designed with theoretical
analysis, to secure the proper rate of balance (rate which negates the inertia
power of a reciprocating movement) while reducing its weight.
Edge Shape Designed With Hydrodynamic.
At high RPM, counterweight rotates at more than 200km/h inside the crankcase
through the oil and air. Tomei designed the edge shape of the counter weight
hydro-dynamically sharp so that less resistance will occur even at high
rotation.
Highest Quality That Will Meet The Demands Of The Top Tuners:
Despite Tomei applying world's highest level of designing ideas such as sharp
edged counterweight or crossing 2way crank lubrication, Tomei succeeded in
controlling every optimized process of the production perfectly, and secured
stable supply of the highest quality of products. From the selection of the
material, heat treatment, and to the polishing process are perfectly managed,
and at the final checking process, 20 items check list are given to the 120 part
of the single crankshaft in the room fixed its temperature at just 20 C.
World's greatest performance as 2.6 liter inline 6 engine, 10,000 RPM is only
achieved by Tomei's quality management that would be match for the world's top
class racing camshafts.
