Brakes
Dragging brakes increase fuel consumption. They should be checked
regularly. It is important that the release action of the air valves is fast
and that the moving parts of the wheel brakes are checked for good
adjustment and operation.
Axles
An axle out of alignment increases rolling resistance. Regularly check
the front wheel alignment and axles on both the tractor and
trailer/semi-trailer. If they are correct, there will be less rolling
resistance and, therefore, lower fuel consumption.
A good sign of an axle or wheel out of alignment is uneven tire wear.
Check the tires often.
Engine
Faulty or incorrectly adjusted engine components increase fuel
consumption. The list below gives some typical components that can
influence fuel consumption:
앫 Blocked (on the outside) charge air cooler/radiator package
앫 Faulty thermostat
앫 Blocked fuel filters
앫 Blocked air intake filter
앫 Faulty injectors
앫 Dirty turbocharger
앫 Air in fuel system
앫 Faulty fuel supply pump
앫 Faulty fuel relief valve
앫 Faulty fan thermostat/clutch
