Diesel Generator Fuel Consumption: Complete Guide with Formulas.

Fuel is the largest operating cost for any Generador diésel. Understanding how to calculate and optimize consumo de combustible directly impacts your total cost of ownership (costo total de propiedad). This guide covers formulas, data tables, and practical reduction tips.

Fuel Consumption Formula

The standard formula for estimating diesel consumption:

Consumption (l/h) = Generator kVA × 0.8 (FP) × Load % × 0.25 L/kWh

El 0.25 L/kWh factor is approximate for modern diesel Generadores en 75% carga. Actual consumption varies by engine brand, edad, y condiciones de funcionamiento.

Clasificación kVA	25% Carga	50% Carga	75% Carga	100% Carga
100 kVA	5.0 l/h	10.0 l/h	15.0 l/h	20.0 l/h
250 kVA	12.5 l/h	25.0 l/h	37.5 l/h	50.0 l/h
500 kVA	25 l/h	50 l/h	75 l/h	100 l/h
1000 kVA	50 l/h	100 l/h	150 l/h	200 l/h
2000 kVA	100 l/h	200 l/h	300 l/h	400 l/h

What Affects Fuel Consumption

Nivel de carga — Generators are most efficient at 70-80% carga
Engine Make — Cummins and MTU typically achieve 5-10% better fuel economy than budget brands
temperatura ambiente — Cold starts increase Consumo de combustible
Altitud — Above 1000m, engines consume more fuel per kWh due to derating
Mantenimiento — Clogged filters increase consumption by 3-5%
