Which driving practice should be applied to effectively reduce fuel consumption in a heavy vehicle?

Question

DentroTest · Accepted Answer

In efficient and economical driving of heavy vehicles, keeping a constant speed is essential. Continual changes of pace, sudden accelerations and unnecessary braking force the vehicle to overcome its inertia again and again, driving up fuel consumption because of the truck's large mass. Driving for most of the route in low gears is a mistake: it needlessly raises the engine speed in revolutions per minute (rpm) and the consumption; the right approach is to use the highest gear possible without leaving the economical zone of the rev counter (green zone). Avoiding engine braking altogether is not effective either: when decelerating in gear without pressing the accelerator, the engine cuts off the fuel injection and consumes almost nothing, and it also relieves the service brakes and prevents them from overheating.
