1. What is the Diesel Generator Consumption Equation?

The Diesel Generator Consumption Equation calculates fuel consumption rate based on the generator's load and efficiency. It helps estimate how much fuel a generator will use under specific operating conditions.

2. How Does the Calculator Work?

The calculator uses the consumption equation:

Where:

• \( Load \) — Power demand on the generator (kW)
• \( Efficiency \) — Generator's fuel efficiency (kW/liter/hour)
• \( Consumption \) — Fuel consumption rate (liters/hour)

Explanation: The equation shows that fuel consumption increases with higher load and decreases with better efficiency.

3. Importance of Consumption Calculation

Details: Accurate fuel consumption estimation is crucial for operational planning, fuel budgeting, and determining generator runtime with available fuel.

4. Using the Calculator

Tips: Enter load in kW and efficiency in kW/liter/hour. Both values must be positive numbers for valid calculation.

5. Frequently Asked Questions (FAQ)

Q1: What's typical efficiency for diesel generators?
A: Efficiency varies but typically ranges from 0.25 to 0.4 kW/liter/hour depending on generator size and technology.

Q2: How does load affect consumption?
A: Consumption increases linearly with load. A generator at 50% load will use about half the fuel of full load operation.

Q3: Should I use peak or average load?
A: For fuel estimation, use average expected load. For capacity planning, consider peak loads.

Q4: Are there other factors affecting consumption?
A: Yes, ambient temperature, altitude, fuel quality, and maintenance condition can all affect actual consumption.

Q5: How accurate is this calculation?
A: It provides a good estimate but actual consumption may vary by ±10-15% depending on operating conditions.
