Calculate the power output of a gasoline engine based on displacement, RPM, and efficiency

Input Parameters

Calculation Results

Calculation Formula

Power (HP) = [(Displacement × RPM × Efficiency) ÷ 9550] × Power RPM ÷ Max RPM

Where:
- Displacement: Engine displacement in cubic centimeters
- RPM: Revolutions per minute
- Efficiency: Engine efficiency as percentage
- 9550: Conversion factor from watts to horsepower
- Power RPM: RPM at which power is calculated
- Max RPM: Maximum engine RPM

Gasoline Power Output Calculator Calculator Usage Guide

Learn how to use the Gasoline Power Output Calculator and understand its working principles

How to Use This Calculator

  1. Enter the engine displacement in cubic centimeters (cc)
  2. Input the maximum RPM of the engine
  3. Set the engine efficiency percentage (typically between 20-40% for gasoline engines)
  4. Specify the RPM at which you want to calculate the power (e.g., peak power RPM)
  5. Click the "Calculate" button to compute the power output in horsepower and approximate torque

Understanding the Formula

This calculator uses the following formula to estimate power output:

Power (HP) = [(Displacement × RPM × Efficiency) ÷ 9550] × Power RPM ÷ Max RPM

This formula estimates power by considering the engine's displacement, operating RPM, efficiency, and the specific RPM at which power is being calculated.

Typical Applications

  • Comparing engine performance across different vehicles
  • Estimating potential power output for engine modifications
  • Understanding how engine displacement relates to power output
  • Quick reference for engine specifications comparison

Important Notes

This calculator provides an estimation based on theoretical inputs. Actual power output may vary due to factors such as:

  • Engine condition and maintenance
  • Altitude and atmospheric pressure
  • Ambient temperature
  • Engine tuning and calibration
