METHOD OF CONTROLLING A HOMOGENOUS-CHARGE COMPRESSION-IGNITION ENGINE

摘要

The invention relates to a method of controlling a homogenous-charge compression-ignition engine. According to the invention, a homogenous-charge compression-ignition piston engine comprises an ionisation detector (5) supplying an ionisation signal I(t) which is associated with the combustion in a cylinder (12), and at least one actuator (7, 21, 10, 10') which acts on one operating parameter of the motor. The inventive engine control method consists in: processing the ionisation signal (I(t)) in order to determine a maximum pressure instant ( alpha Pmax); comparing the maximum pressure instant ( alpha Pmax) with a set value for the maximum pressure instant ( alpha PmaxC); and acting on at least one operating parameter of the engine such that the maximum pressure instant ( alpha Pmax) corresponds to the set value ( alpha PmaxC).
