2l material scm435 chrome Molly steel oem steel stroke mm forged scm435 metal Tomei selected chrome Molly steel as a material std regular steel and forge it in the mold to improve the organization of crystal. Applied to Sr engine PC finish to the pulley journal PC finish prevents pulley and pulley holder to be worn and keeps good maintenance of the engine. Edge shape designed with hydrodynamics at high rpm, counterweight rotates at more than 200kminside the crankcase through the oil and air.
5mm, it is difficult to guarantee the metals strength. Special features nitrite surface treatment minimal heat treatment distortion minimal size change no reduction in the cores strength resistance to abrasions burn characteristics metal protection suited for high output compatibility suited for high revolution improvement durability note since the metals width is quite narrow for the EJ20 16.
Tomei designed the edge shape of the counterweight hydro dynamically sharp so that less resistance will occur even at high rotation. 2l EJ22 features crankshaft is the parts that change vertical movement of a piston into rotational movement. As a result, metal flow is formed along with the shape of crankshaft that gives 2 times more strength to the metal than before.
Furthermore, and resistance of oil flow is reduced by giving a modification on oil hole exit. 7 turns per second which is translated in 56. It is suffered from explosion load and inertia power, and the load by bend vibration or torsion vibration. 1 km of peripheral speed.
The end result was an improved metal characteristic that reaches an acceptable level. 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.
0 weight kg 9. Applied to Rb engines PC finish is shooting micro ceramic spheres 45mm diameter to the surface of the metal at 200mof speed. Full counter weighted camshaft by preparing counter weight on every cylinder, making inertia power balance so that bent of the crankshaft is suppressed and vibration and friction is reduced, while the reliability of bearing is raised.
When the engine is running at 8500rpm, crank rotates so to avoid engine trouble from metal burns Tomei had to increase the surface hardness by using the Palestine hardening process. 7 modem oem 75.
