Diesel Generator Fuel Consumption: Complete Guide with Formulas.

Fuel is the largest operating cost for any Générateur diesel. Understanding how to calculate and optimize consommation de carburant directly impacts your total cost of ownership (Coût total de possession). This guide covers formulas, data tables, and practical reduction tips.

Fuel Consumption Formula

The standard formula for estimating diesel consumption:

Consumption (L/heure) = Generator kVA × 0.8 (PF) × Load % × 0.25 L/kWh

Le 0.25 L/kWh factor is approximate for modern diesel Générateurs à 75% charger. Actual consumption varies by engine brand, âge, et conditions de fonctionnement.

Valeur nominale kVA	25% Charger	50% Charger	75% Charger	100% Charger
100 kVA	5.0 L/heure	10.0 L/heure	15.0 L/heure	20.0 L/heure
250 kVA	12.5 L/heure	25.0 L/heure	37.5 L/heure	50.0 L/heure
500 kVA	25 L/heure	50 L/heure	75 L/heure	100 L/heure
1000 kVA	50 L/heure	100 L/heure	150 L/heure	200 L/heure
2000 kVA	100 L/heure	200 L/heure	300 L/heure	400 L/heure

What Affects Fuel Consumption

Niveau de charge — Generators are most efficient at 70-80% charger
Engine Make — Cummins and MTU typically achieve 5-10% better fuel economy than budget brands
température ambiante — Cold starts increase Consommation de carburant
Altitude — Above 1000m, engines consume more fuel per kWh due to derating
Entretien — Clogged filters increase consumption by 3-5%
