The most common types of low-frequency noise in condensed matter systems are: (I) the Johnson or thermal noise, that is the electronic noise generated by the thermal agitation of the charge carriers (usually the electrons) inside an electrical conductor at equilibrium; (II) the shot noise, ...
Therefore, for the long service life of the engine, it is necessary to carefully consider an appropriate design and the efficiency of the intake air filtration [2,3]. Regardless of the design and operational conditions, as well as servicing quality, engine crankshaft–piston assembly still ...
