Abstract

The scientific bases of new noise mufflers designs of internal combustion engines, providing the gas flows release with improved gas dynamic and acoustic characteristics are presented. Innovative models of noise silencers of reciprocating internal combustion engines with improved hydraulic and acoustic characteristics based on the theory of
numbers, and confusor-diffuser inserts having the form of a Venturi pipe are proposed. The gas flow along the entire length of the noise silencer body from the inlet pipe to the exhaust is monitored and controlled with their help. As
a result, effective noise reduction occurs at the lowest possible hydraulic (aerodynamic) resistance.
