BMEP Calculator

Inputs

Engine torque (T)

Measured brake torque at the crankshaft.

N·m

Displacement (V_d)

Total engine displacement.

cm³

Engine cycle

Four-stroke engines complete one power cycle every two crank revolutions; two-strokes every one revolution.

Method notes 2 notes

BMEP is a useful normalized torque metric. It is not cylinder pressure or peak combustion pressure.
Boosted, racing and highly developed engines can exceed conservative screening ranges; compare like engine types and duty cycles.
