A method of controlling an internal combustion engine having at least a cylinder that defines a variable volume combustion chamber and a rotating shaft that receives the motion from a piston mounted sliding inside the cylinder. The method of control includes the steps of: determining a window of detection in crankshaft angle degrees and having a start angle and a stop angle, detect and store the intensity of acoustic pressure waves generated by the internal combustion engine as a function of crankshaft angle through at least one acoustic pressure sensor and in the window of detection, and estimate the value of at least one functional parameter of a component of internal combustion engine by analyzing the intensity of acoustic pressure waves in the window of detection.

Abstract

A method of controlling an internal combustion engine having at least a cylinder that defines a variable volume combustion chamber and a rotating shaft that receives the motion from a piston mounted sliding inside the cylinder. The method of control includes the steps of: determining a window of detection in crankshaft angle degrees and having a start angle and a stop angle, detect and store the intensity of acoustic pressure waves generated by the internal combustion engine as a function of crankshaft angle through at least one acoustic pressure sensor and in the window of detection, and estimate the value of at least one functional parameter of a component of internal combustion engine by analyzing the intensity of acoustic pressure waves in the window of detection.
