Lorry (Truck) Fuel Consumption Calculator

Lorry (Truck) Fuel Consumption Guide

Estimate fuel consumption for trucks to optimize logistics and reduce operational costs.

How It Works

The calculator computes fuel consumption in liters per 100 km based on the distance traveled and fuel used, with adjustments for load, terrain, and driving style. The cost is calculated by multiplying the fuel used by the fuel price per liter.

Fuel Consumption (L/100 km) = (Fuel Used (L) / Distance (km)) × 100 × Adjustment Factor

Fuel Cost = Fuel Used (L) × Fuel Price (per liter)

Adjustment Factors

Factor	Condition	Adjustment
Load Percentage	Empty (0%)	-20%
Load Percentage	Half Load (50%)	No adjustment
Load Percentage	Full Load (100%)	+20%
Terrain	Flat (Highway)	No adjustment
Terrain	Hilly	+15%
Terrain	Mountainous	+30%
Driving Style	Normal	No adjustment
Driving Style	Aggressive	+20%
Driving Style	Eco-Driving	-10%

Key Factors Affecting Fuel Consumption

• Load: Heavier loads increase fuel consumption due to higher energy requirements.
• Terrain: Hilly or mountainous terrain increases fuel burn compared to flat highways.
• Driving Style: Aggressive driving (rapid acceleration, high speeds) increases consumption, while eco-driving reduces it.
• Engine Type: Diesel is common for efficiency, hybrids save fuel in stop-start conditions, and CNG is greener but may have lower power.
• Maintenance: Poorly maintained engines or tires reduce fuel efficiency.

Example Calculation

For a truck traveling 100 km, using 30 liters of diesel at ₹90 per liter, with a full load on hilly terrain and normal driving:

Base Consumption = (30 L / 100 km) × 100 = 30 L/100 km

Adjustment = 1.2 (full load) × 1.15 (hilly) = 1.38

Adjusted Consumption = 30 × 1.38 = 41.4 L/100 km

Fuel Cost = 30 L × ₹90 = ₹2700

Tips for Improving Fuel Efficiency

• Eco-Driving: Use smooth acceleration and maintain steady speeds.
• Regular Maintenance: Keep engines and tires in optimal condition.
• Optimize Load: Avoid overloading and balance loads evenly.
• Route Planning: Choose flat routes when possible to reduce fuel use.

Final Considerations

Accurate fuel consumption tracking helps optimize logistics, reduce costs, and lower emissions. Consider hybrid or CNG trucks for greener operations where applicable.
