Safe limits engine RPM to seker (piston)

motion of the piston in the engine

As the moving parts, Piston also has a speed LIMIT Ideal SAFE or commonly called by PISTON SPEED Race in the world. "Piston Speed" is a guideline figure for the manufacturer and Mechanical Enginering Racing in Formula Concocting the machine that will be on the rise and, because of the "Piston Speed" this can be determined resilience and character of his new machine Later.
The Ideal Piston Speed ​​(PS) is 21 meters / sec (21 m / s)
And to calculate the Piston Speed ​​Vehicle Using Formulas can:
(2 x Stroke # # in meters x rpm) / 60
* The number "2" is representative of the motion of the piston up and down when the engine rotates one full rotation.
* stroke / piston must step in compression from millimeter to meter
* RPM is the highest round of the desired machine.
* And / 60 represents the transfer of rotation RPM (Rotary Per-Minute) to sec (second)
