Calculate Brake Mean Effective Pressure for internal combustion engines

📖 Brake Mean Effective Pressure

BMEP is the average pressure that, if applied uniformly during the power stroke, would produce the measured brake power output. It's a measure of engine efficiency and performance.

💡 Tips & Information

  • BMEP is typically measured in bar or psi (pounds per square inch)
  • Higher BMEP indicates better engine efficiency and power output
  • Typical values range from 8-12 bar for naturally aspirated engines
  • Turbocharged engines can achieve 15-25 bar BMEP
  • BMEP is independent of engine size, making it useful for comparing different engines
