Type
String defining type of
auxiliary. Click arrow to load from a predefined list.
ID
The ID string is required
to link the auxiliary to the corresponding supply power definition in
the driving cycle. The ID must not contain space or special characters
(text and numbers only). The ID is not case sensitive (e.g. "ALT" will link
to "Alt" or "alt", etc.)
Example: Auxiliary "ALT" is linked to
the column "<AUX_ALT>" in the driving cylce.

Example:
Calculation of auxiliary power consumption

- Auxiliary speed: nAux = nEng * TransRatio (with: nEng = engine speed)
- Auxiliary output power: PAuxOut = Psupply / EffToSply
- Auxiliary input power: PAuxIn = AuxMap(nAux, PAuxOut)
- Auxiliary power consumption: PAuxDemand = PAuxIn / EffToEng
- PAuxDemand is added to the engine's power demand
