ABSTRACT:
The invention relates to a method for adjusting the operation parameters of an injection internal combustion engine (10), that comprises the following steps: setting a stability setpoint Ss, calculating an engine stability index Is, calculating the stability deviation Es equal to the difference between the stability setpoint Ss and the stability index Is, processing the stability deviation Es using a regulator (18) that provides an setpoint to be applied to one of the engine operation parameters, said parameter being selected by a calculator (20) or supervisor that controls the adjustment so that the corrective action applied optimizes the effluent level and/or the thermal energy available at the exhaust while respecting the stability setpoint Ss.
