METHOD AND DEVICE FOR DETERMINING COMBUSTION NOISE PARAMETERS

A method and a device for determining combustion noise parameters, comprising acquiring a cylinder pressure sequence which comprises cylinder pressures corresponding to different crank angles ϕ and corresponding moments tϕ; calculating a first parameter sequence according to the cylinder pressure sequence, wherein the first parameter sequence is a parameter sequence in a time domain, and the first parameter sequence comprises one or more of a top surface cylinder force sequence, a top surface cylinder force rise rate sequence, a side surface cylinder force sequence and a side surface cylinder force rise rate sequence; and determining a target parameter for representing combustion noise in the cylinder according to the first parameter sequence.
