    摘要: An engine control, and in particular a method for controlling an engine including a low-pressure exhaust gas recycling loop. The method adjusts a predetermined engine operating parameter by controlling the position of an exhaust gas recycling valve, which is placed in the loop, for determining whether the predetermined measured quantity of the valve respects a predetermined criteria, and controls the position of an exhaust shutter, which is arranged outside the loop, when the quantity does not respect the criteria.

    摘要: A method for diagnosing a condition of a system for supplying fuel to a fuel injected controlled-ignition internal combustion engine, of a type including an electric control device that makes use of an oxygen probe for closed-loop regulation of a value of an air/fuel ratio admitted to the combustion chambers of the engine, and according to which a signal delivered by the oxygen probe is analyzed, the method a) deducing from the signal a change in injection time correction factor ALPHACL_MEAN making it possible to regulate richness of exhaust gases leaving the engine; b) comparing ALPHACL_MEAN against predetermined minimum and maximum threshold values THRESHOLD_MIN and THRESHOLD_MAX; c) diagnosing a defective condition when ALPHACL_MEAN is outside of a window included between THRESHOLD_MIN and THRESHOLD_MAX.
