The Stribeck curve for a system in the presence of friction was analyzed, the friction-induced noise parameters were listed, and the expression of the friction-induced noise was derived. In addition, considering three axioms in tribology, three research aspects about the friction-induced noise of the engine were discussed, including the generating mechanism of the friction-induced noise, the quantification of the friction-induced noise, and the formation, size, and number of worn-out particles with their effect on the friction-induced noise.
