brake mean effective pressure
English Meaning & Definitions
A theoretical average pressure calculated by dividing the brake power of an internal combustion engine by the displacement volume and the number of power strokes per cycle, used as a standard metric to compare engine performance regardless of size.
- “Engineers use brake mean effective pressure to compare the efficiency of different engine designs independent of their displacement.”
- “A higher brake mean effective pressure generally indicates a more efficient and powerful engine for its size.”

Compare formal, informal, literary synonyms and register nuances for “brake mean effective pressure”.
The term originates from mechanical engineering in the late 19th century. 'Brake' refers to the use of a dynamometer (a brake) to measure the actual power output at the crankshaft, distinguishing it from 'indicated' pressure measured inside the cylinder. 'Mean effective' denotes the theoretical average pressure that, if applied constantly during the power stroke, would produce the observed power output.
B.M.E.P.: 'Brake Means Engine Power'—a simple way to remember that this value directly correlates to the usable power an engine produces.
