Description
The Engine File (.veng) defines all engine-related parameters and input files like Fuel Consumption Map and Full Load Curves.
Relatve File Paths
It is recommended to define
relative filepaths. This way the Job File and all input files can be
moved without having to update the paths.
Example: "Demo\FLD1.vfld" points to the "Demo" subdirectory of the Engine File's directoy.
VECTO automatically uses relative paths if the input file (e.g. FC Map)
is in the same directory as the Engine File. (The Engine File must be
saved before browsing for input files.)
Main Engine Parameters
Make
and Model
Free text defining the
engine model, type, etc.
Idling
Engine Speed [rpm]
Low idle, applied in
simulation for vehicle standstill in neutral gear position.
Displacement
[ccm]
Inertia
including Flywheel [kgm
2]
Inertia for rotating parts
including engine flywheel
. In
Declaration Mode the inertia is calculated automatically.
Full Load and Drag Curves
Multiple
Full Load and Drag Curves (.vfld) can be defined and assigned
to different gears. Gear "0" must be assigned for idling and
Engine Only Mode.
Use the

and

buttons to add or
remove .vfld files. Doubleclick entries to edit existing configurations.
The input file (.vfld) file format is described
here.
Fuel Consumption Map
The
Fuel Consumption Map is used to calculate the base FC value. See
Fuel Consumption Calculation for details.
The input file (.vmap) file format is described
here.
WHTC Test Results
The WHTC test results are required in
Declaration Mode for the
WHTC FC Correction. The fuel consumption must be defined in [g/kWh] for each test part (Urban, Rural, Motorway) separately.
Chart Area
The Chart Area shows the fuel consumption map and the selected full load curve.
