How do you check the diesel consumption of construction machines?
Divide the litres of diesel issued to a machine by the hours it worked, taken from its hour meter, to get litres per hour. Compare that with the same machine’s normal figure for the same kind of work. A sudden rise points to a fault, idling, or fuel leaving the site.
Also called: Litres per hour, Fuel norm, Diesel consumption per hour.
The normal figure depends on the machine, its age and the work, so the best benchmark is that machine’s own recent history, not a catalogue number.
The check only works if hour-meter readings are continuous. If today’s opening reading does not equal yesterday’s closing, the gap hides either hours or fuel.
Litres per hour = diesel issued ÷ (closing hour-meter reading − opening reading)
A machine that normally burns 6.1 litres per hour shows 8.7 one day: 43% above normal, and worth a question the same day.
In ERP Infra
Diesel is treated as stock and issued to each machine. Opening readings carry over automatically, and litres per hour are compared with the machine’s normal every day.
