F - CONDITIONS FOR ACTIVATING REGENERATION ASSISTANCE (BY THE
MONITORING FUNCTION)
Parameters which can activate regeneration assistance:
• pressure differential,
• distance travelled between each regeneration.
PARAMETERS REGENERATION ASSISTANCE
Pressure differential Activation Pressure differential
(above a limit "E")
Deactivation Effective post-injection time
(above a limit "K")
Distance Activation Distance travelled since last
regeneration (above a limit "J")
Deactivation Effective post-injection time
(above a limit "K")
G - PRESSURE DIFFERENTIAL
The pressure differential parameter is used to activate regeneration assistance
independently to the distance information.
When this condition is responsible for determining activation of regeneration
assistance, an effective post-injection time must have elapsed before
regeneration assistance can be stopped (this allows complete soot combustion,
in normal operation).
Monitoring the post-injection time:
• prevents the post-injection time being too long (damage to the engine,
expansion of the engine oil),
• limits fuel consumption.
