Fuel Consumption Formula:
| From: | To: |
Fuel consumption calculation estimates the amount of fuel an engine consumes per hour based on engine size, load factor, and specific fuel consumption. This is essential for operational planning, cost estimation, and efficiency analysis.
The calculator uses the fuel consumption formula:
Where:
Explanation: The equation calculates hourly fuel consumption by multiplying engine power by the load percentage and the engine's specific fuel consumption rate.
Details: Accurate fuel consumption estimation is crucial for budgeting, operational planning, environmental impact assessment, and efficiency optimization in various industries including transportation, construction, and marine operations.
Tips: Enter engine size in horsepower, load factor as a decimal between 0 and 1, and specific consumption in liters per horsepower per hour. All values must be positive numbers.
Q1: What is a typical specific consumption value for diesel engines?
A: Most diesel engines have specific consumption values between 0.15-0.25 l/hp h, but this varies by engine type, age, and condition.
Q2: How accurate is this calculation?
A: This provides a good estimate but actual consumption may vary based on engine condition, fuel quality, operating conditions, and maintenance status.
Q3: Can this formula be used for gasoline engines?
A: Yes, but specific consumption values for gasoline engines are typically higher, usually in the range of 0.25-0.35 l/hp h.
Q4: How does load factor affect fuel consumption?
A: Higher load factors increase fuel consumption proportionally. An engine at 80% load consumes approximately 80% of its maximum fuel consumption rate.
Q5: Should this calculation be used for long-term fuel planning?
A: For precise long-term planning, consider additional factors like idle time, varying loads, and environmental conditions that may affect actual consumption.
