This article will explore each of these infl uencers in detail,
explaining the parameters and overall interaction of these on
fuel effi ciency.
Fuel effi ciency
Fuel effi ciency is defi ned as material moved (work) in a time pe-
riod over the amount of fuel consumed to move the material in
the same time period. The fuel effi ciency formula for aggregates
equipment appears as:
Fuel effi ciency =
Material moved per unit of time
Fuel consumed per unit of time
To put this formula into plain terms from an application
point of view, material moved, also known as productivity, is
measured in tons or cubic yards. Fuel consumed is measured
in gallons used to move the material. The unit of time for fuel
effi ciency is an hourly measurement, which results in units of
tons per gallon or cubic yards per gallon.
Based on this, improvements in fuel effi ciency are achieved
In truck loading applications, an experienced equipment operator has
more than a 30-percent fuel efficiency advantage over a novice.
