Mean Piston Speed Calculator

Formula

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

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

Where:

\( MPS \) is the mean piston speed (m/s).
\( S \) is the stroke length (mm).
\( RPM \) is the rotations per minute of the engine.

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:

Stroke Length (S): 100 mm
Rotations per Minute (RPM): 3000

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.
