Where F is the fuel consumption in L t−1;
P is the power delivered in kW,
which is assumed as the full load
of the machine based on its engine capacity;
s is the specific diesel consumption in g(kWh)−1,
which is selected as the maximum consumption ranging from 280
to 320 g(kWh)−1 (DLG, 2016); m is the engine load in%; and is the
specific weight of diesel, which is 0.832 kg l
−1 (UFA, 2016).
