Notes:
- Ensure all inputs are positive numbers for accurate results.
- The stroke length is automatically converted from cm or mm to meters.
- The piston speed is calculated and displayed in meters per second (meters/s).
FAQ
Piston speed is calculated using the formula: Piston Speed = (Stroke Length × RPM) / 60. This provides the speed in feet per minute or meters per minute.
Acceptable piston speeds typically range from 4,000 to 5,000 feet per minute for standard engines, while high-performance engines may tolerate higher speeds.
Piston speed impacts engine efficiency and wear. Higher speeds can lead to increased friction and heat, potentially reducing engine life if not properly managed.
While there isn't a universal maximum, it's often recommended to keep piston speeds below 5,500 feet per minute for typical applications to ensure durability.
At 5,000 RPM: Approximately 3,571 feet per minute.
At 6,000 RPM: Approximately 4,286 feet per minute.
At 7,000 RPM: Approximately 4,900 feet per minute.
Piston speed is influenced by stroke length, RPM, engine design, and intended use. Any changes to these parameters can significantly affect piston speed.
High piston speeds increase mechanical stress, friction, and heat on engine components, potentially leading to premature failure. Managing piston speed is crucial for long-term durability.
