Engine speed is measured in revolutions per minute (RPM). Engines may be classified as low-speed, medium-speed or high-speed but these terms are inexact and depend on the type of engine being described.

Famous quotes containing the words speed and/or engine:
“If it be aught toward the general good,
Set honor in one eye, and death ith other,
And I will look on both indifferently;
For let the gods so speed me as I love
The name of honor more than I fear death.”
