Engine Brake Mean Effective Pressure (\(BMEP\)):

\[ BMEP = \frac{75 \cdot 50 \cdot BHP}{L \cdot A \cdot N \cdot n} \]

Where:

• \(BMEP\) is the brake mean effective pressure, kg/cm².
• \(BHP\) is the brake horsepower, hp.
• \(L\) is the piston stroke, m.
• \(A\) is the piston area, cm².
• \(N\) is the number of power strokes per minute.
• \(n\) is the number of cylinders.
