Title:
METHOD FOR UPDATING A DYNAMIC FOR ADJUSTING A RICHNESS VALUE TO A SET VALUE IN AN ENGINE
Document Type and Number:
WIPO Patent Application WO/2018/202977
Kind Code:
A3
Abstract:
The invention relates to a method for updating a dynamic for adjusting a measured richness to a richness set value for an air/fuel mixture in a heat engine when at least one pre-determined engine operating condition (cond1 to condx) is in effect, a nominal richness adjustment dynamic (Dyn nom) being replaced by an updated adjustment dynamic (Dyn fin) specific to the at least one condition (cond1 to condx). Upon detection of a value of at least one engine operating parameter indicating that the condition (cond1 to condx) is in effect, a correction is made to the nominal dynamic (Dyn nom) according to a weighting term (Fpond) in order to supply an updated dynamic (Dyn fin) as long as the value is detected.
