1. What is Specific Fuel Consumption?

Specific Fuel Consumption (SFC) is a measure of the fuel efficiency of an engine that burns fuel and produces power. It represents the fuel flow rate per unit of power output.

2. How Does the Calculator Work?

The calculator uses the SFC formula:

Where:

• \( Fuel\ Used \) — Amount of fuel consumed (grams)
• \( Power\ Output \) — Engine power output (kilowatts)

Explanation: The equation calculates how much fuel is needed to produce one unit of power.

3. Importance of SFC Calculation

Details: SFC is crucial for comparing the efficiency of different engines, optimizing fuel consumption, and assessing engine performance.

4. Using the Calculator

Tips: Enter fuel used in grams and power output in kilowatts. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical SFC values?
A: Typical values range from 200-300 g/kWh for diesel engines and 250-350 g/kWh for gasoline engines.

Q2: How does SFC relate to engine efficiency?
A: Lower SFC values indicate better fuel efficiency as less fuel is needed to produce the same power.

Q3: What factors affect SFC?
A: Engine design, operating conditions, load, speed, and maintenance all affect SFC.

Q4: Is SFC the same as BSFC?
A: BSFC (Brake Specific Fuel Consumption) is essentially the same as SFC when referring to brake power output.

Q5: How can I improve SFC?
A: Regular maintenance, optimal engine loading, and using the right fuel can help improve SFC.
