Abstract
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.
