Fuel Consumption to Engine Efficiency

Fuel Consumption to Engine Efficiency Converter

Calculate an engine's **Brake Thermal Efficiency** (in %) by providing its power output, fuel consumption rate, fuel density, and the fuel's calorific value.

For more accurate results, use the **Lower Heating Value (LHV)** of your fuel.

Brake Power (Engine Output):

Fuel Consumption Rate:

Fuel Density:

Typical: Gasoline ~0.72-0.78 kg/L, Diesel ~0.83-0.86 kg/L

Fuel Calorific Value (LHV):

Typical LHV: Gasoline ~44-45 MJ/kg, Diesel ~42-43 MJ/kg
