Brake Specific Fuel Consumption Calculator

This calculator calculates the brake specific fuel consumption (BSFC) of an engine, which is the amount of fuel consumed per unit of power output. It's commonly used in engine performance analysis and optimization.

Input Parameters

Calculation Results

Calculation Formula

BSFC = Fuel Flow Rate / Brake Power

Where:
BSFC = Brake Specific Fuel Consumption (g/kW)
Fuel Flow Rate = Fuel consumption rate (g/s)
Brake Power = Engine output power (kW)

Brake Specific Fuel Consumption Calculator Usage Guide

Learn how to use the Brake Specific Fuel Consumption Calculator and its working principles

How to Use This Calculator

  1. Enter the Brake Power in kilowatts (kW). This is the power output of the engine at the brake (output shaft).
  2. Enter the Fuel Flow Rate in grams per second (g/s). This is the rate at which fuel is consumed by the engine.
  3. Optionally, enter the Engine Speed in revolutions per minute (RPM) for additional analysis.
  4. Click the "Calculate" button to compute the BSFC.
  5. The result will be displayed in grams per kilowatt (g/kW), indicating how much fuel is consumed per kilowatt of power output.

Understanding Brake Specific Fuel Consumption (BSFC)

Brake Specific Fuel Consumption (BSFC) is a measure of engine efficiency. It represents the amount of fuel consumed per unit of power output. A lower BSFC indicates a more efficient engine.

Formula

BSFC = Fuel Flow Rate (g/s) / Brake Power (kW)

Applications

  • Engine performance analysis
  • Engine optimization
  • Comparison of different engines or fuel types
  • Calculation of fuel consumption in vehicles

Example

If an engine consumes 10 g/s of fuel and produces 50 kW of brake power, the BSFC would be:

BSFC = 10 g/s / 50 kW = 0.2 g/kW
