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
Enable prime pulse
Batch all injectors
Cranking threshold
Engine stall rev. limit
Cranking ign. angle
Use injectors cal.
DESCRIPTION
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
When this parameter is checked all injectors squirt together at every
ignition event
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
The engine RPM below which the EMU stops executing ignition and
fuel injection
Ignition angle during cranking
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
