# What Is the Fuel Consumption Per Hour in a Diesel Generator

*by Starlight Generator dieselgeneratortech*

This varies widely on
many different factors.

Manufacturer of the
engine

Size of the generator

Load at which you are
testing these values

Generally speaking,
larger **generators** are more efficient when comparing their gallons per kVA, same
with the gallons per hour. Please note that you should try not to operate a
diesel generator at less than 50% load. Diesel engines operate better on load,
operating without load or with a low load doesn't allow the engine to reach
it's maximum operating temperature and you will have many issues which will
lead to a short product life.

The fuel consumption of
the generator is mainly considered in the following two aspects: the fuel
consumption rate and the fuel consumption rate of different brands of diesel
generator sets are different.

The size of the load,
the load on the throttle large consumption of more, on the other hand, the load
is smaller relative to the fuel consumption.

Most generator
manufacturers use Gr / KW.H, which means how many grams of (G) oil a kilowatt
per hour consumes, and then replaced by a liter of (L) to find out the cost of
fuel consumption per hour.

The specific calculation
method of** diesel generator** fuel consumption is as follows: one liter of diesel
oil is equal to about 0.84-0.86 kg (1L=0.8-0.85KG). Most diesel-generator
manufacturers use Gr / KW.H, which means how many grams of (G) oil a kilowatt
per hour consumes, and then replaced by a liter of (L) to get an idea of the
cost of your fuel consumption per hour.
