Fuel Consumption Formula

The standard formula for estimating diesel consumption:

Consumption (L/h) = Generator kVA × 0.8 (ПФ) × Load % × 0.25 Л/кВтч

Лийшаш 0.25 L/kWh factor is approximate for modern diesel Генератор-влак саат 75% нагрузко. Actual consumption varies by engine brand, ийгот, да паша условий.

кВА рейтинг	25% Нагрузко	50% Нагрузко	75% Нагрузко	100% Нагрузко
100 кВА	5.0 L/h	10.0 L/h	15.0 L/h	20.0 L/h
250 кВА	12.5 L/h	25.0 L/h	37.5 L/h	50.0 L/h
500 кВА	25 L/h	50 L/h	75 L/h	100 L/h
1000 кВА	50 L/h	100 L/h	150 L/h	200 L/h
2000 кВА	100 L/h	200 L/h	300 L/h	400 L/h

What Affects Fuel Consumption

Нагрузко кӱкшыт — Generators are most efficient at 70-80% нагрузко
Engine Make — Cummins and MTU typically achieve 5-10% better fuel economy than budget brands
йырым-йырысе температур — Cold starts increase Топливо кучылтмаш
Кӱкшыт — Above 1000m, engines consume more fuel per kWh due to derating
Технический обслуживатлыме — Clogged filters increase consumption by 3-5%
