CONFIGURATION OF ENGINE START PARAMETERS
Settings in the parameter group Engine Start are used in the start-up phase of the engine.
Parameters
The Engine start parameters menu defines parameters like ignition angle, injectors configuration
and other important parameters related to the engine cranking phase.
The Cranking fuel table defines the injector opening time as a function of engine coolant
temperature. In addition, the Fuel TPS scale table defines the injector opening time correction as a
function of throttle position. Using this table, an anti flood strategy can be enabled.
PARAMETER DESCRIPTION
Enable prime pulse
This parameter enables a single fuel dose when the engine is
cranked, but before synchronization has been achieved. This function
can improve engine starting. The injector opening time during prime
pulse is defined in Prime pulse table
Batch all injectors
When this parameter is checked all injectors squirt together at every
ignition event
Cranking threshold
If the engine RPM is higher than Cranking threshold value, the EMU
will change state from Cranking to Afterstart and the fuel dose will be
calculated based on the VE table
Engine stall rev. limit
The engine RPM below which the EMU stops executing ignition and
fuel injection
Cranking ign. angle Ignition angle during cranking
Use injectors cal.
This option enables battery correction of injectors opening time from
tables Prime pulse and Cranking fuel. The battery calibration table is
defined in Fueling injectors cal. table
