What is the average piston speed of a seven-cylinder, two-stroke/cycle diesel engine with a 580 mm bore and a 1700 mm stroke operating at 100 RPM?

🔍 Key Concepts

• Average piston speed formula for a reciprocating engine • Relationship between stroke length, RPM, and piston travel per minute • Unit conversions between mm and meters and between minutes and seconds

💭 Think About

• First, figure out how many strokes per minute the piston makes in a two-stroke engine running at 100 RPM. Does the piston travel the stroke length once or twice per revolution? • Calculate how far the piston travels in one revolution, then multiply by revolutions per minute to get distance per minute. • Convert the distance per minute into meters per second, then compare your result to the choices.

✅ Before You Answer

• Be sure to convert 1700 mm stroke to meters before calculating speed. • Remember average piston speed is based on total up-and-down travel, not just one direction. • Verify that the number of cylinders (seven) does not change the piston speed formula—each piston has the same stroke and RPM.
