Abstract (en)
[origin: WO2009133281A1] The invention relates to an operational-condition diagnosing system for the gas inlet device of an automobile internal combustion engine that comprises a fresh air inlet duct (28) and an exhaust gas recirculation duct (32) provided with at least one recirculation valve (34, 36), said recirculation duct being connected to an inlet duct and to an exhaust duct provided with a particle filter (54). The system includes means (62, 66) for determining the mass of the particles present in the exhaust line downstream from the particle filter and upstream from the recirculation duct (32), and a control unit (60) adapted for driving the recirculation valve on the basis of the determined particle mass and of the opening percentage of said valve.
