Abstract (en)

The processing system comprises a plurality of sensors (2), each of which detects a corresponding physical magnitude indicative of the operating conditions of the engine (M) and generates a respective detection signal, and a processing unit (3) which receives the detection signals. The processing unit comprises five processing modules (91 to 95) intended respectively to control the following functions: detection of the operation of the engine in conditions that are abnormal or harmful to the life of the engine itself (91); limitation of critical uses of the engine (92); monitoring of the operating conditions (93); updated detection of the maintenance operations to be carried out on the engine (94), and diagnosis of unsatisfactory engine performance (95).
