METHOD TO CONTROL THE COMBUSTION NOISE GENERATED BY A SPONTANEOUSLY-STARTED INTERNAL COMBUSTION ENGINE

Torna indietro

Abstract

Method to control the combustion noise generated by a spontaneously-started internal combustion engine (1) that provides determining a plurality of sequences (SEQInj) of combustion cycles to be carried out through the alternation of combustion cycles with a single main fuel injection and combustion cycles with a plurality of fuel injections; detecting by means of a sensor (5) the intensity of the combustion noise generated by the combustion in the cylinders (3); calculating a reference combustion noise (NOISET); and determining the succession of sequences (SEQInj) of combustion cycles to be carried out for obtaining the reference combustion noise (NOISET) by means of a feedback control using as a feedback variable the intensity of the combustion noise generated by the combustion in the cylinders (3) detected by the sensor (5).
