WebFirstly, instantaneous power is equal to F · v. If we said that F = m · a, and plug that into the instantaneous power, then we would have P = m · a · v. So now we can see that for the power, the mass does matter. Then, the instantaneous speed is a magnitude that is constant by the simple meaning that is in an infinitesimal time interval. WebDurability – The engine useful life (emission durability period, EDP) is defined at Stage III/IV as 3000/5000 hours for engines at or below 37 kW (constant/non-constant speed, respectively) and 8000 hours for engines above 37 kW. Testing Stage I/II engine emissions are measured on the ISO 8178 C1 8-mode cycle and expressed in g/kWh.
