  2. Enter the engine RPM (revolutions per minute).
  3. Enter the compression ratio of the engine.
  4. Click the "Calculate" button to compute the piston acceleration.
  5. The result will be displayed in feet per second squared (ft/s²).

Working Principle

The piston acceleration in a reciprocating engine is a critical parameter that affects engine performance and NVH (Noise, Vibration, and Harshness) characteristics. It is calculated based on the stroke length, engine RPM, and compression ratio. The formula used is:

f = (π * 2 * stroke * rpm² * cr) / 63360

Where:

  • f = Piston Acceleration (feet per second squared)
  • π = Pi (approximately 3.14159)
  • stroke = Piston stroke (inches)
  • rpm = Engine RPM (revolutions per minute)
  • cr = Compression Ratio

Applications

This calculator is useful for engine designers and engineers who need to analyze and optimize piston acceleration for better engine performance, reduced vibration, and smoother operation. Understanding piston acceleration helps in designing engines that balance power output with NVH characteristics.
