Brake-Specific Fuel Consumption (BSFC) Calculator

Calculate Brake-Specific Fuel Consumption (BSFC)



Formula

The formula to calculate the Brake-Specific Fuel Consumption (BSFC) is:

\[ BSFC = \frac{r}{P} \]

Where:

What is BSFC?

BSFC, or Brake-Specific Fuel Consumption, is a measure of the fuel efficiency of an engine that burns fuel to produce rotational power. It represents the amount of fuel consumed per unit of power output and is typically measured in grams per joule (g/J). A lower BSFC value indicates higher fuel efficiency, meaning the engine is using less fuel to produce the same amount of power.

Example Calculation

Let's consider an example:

Using the formula to calculate the Brake-Specific Fuel Consumption (BSFC):

\[ BSFC = \frac{0.5}{1000} = 0.0005 \, \text{g/J} \]

This means the engine has a brake-specific fuel consumption of 0.0005 g/J, indicating the fuel efficiency of the engine.
