Calculate Mean Piston Speed (MPS)



Formula

The formula to calculate the mean piston speed (MPS) is:

\[ MPS = \frac{2 \times S}{1000} \times \frac{RPM}{60} \]

What is Piston Speed?

Piston speed, also commonly known as the mean piston speed, is the velocity of a moving piston inside a combustion engine. It is an important parameter in engine design and performance analysis.

Example Calculation

Consider an example where:

Using the formula to calculate the mean piston speed:

\[ MPS = \frac{2 \times 100}{1000} \times \frac{3000}{60} = 10 \text{ m/s} \]

This means that the mean piston speed for this example is 10 m/s.
