Combustion process for I.C. engine using a resonating air chamber in a reciprocating piston to induce closed organ pipe resonance in the combustion chamber

摘要

Closed organ pipe resonance is induced in the cylinder of a piston I.C. engine by using a resonating mass of gas in a chamber in the piston adjacent its working face, the chamber and cylinder volume being connected by a restricted orifice. The organ pipe resonance is induced during the expansion part of the combustion cycle to cause intimate mixing of the reacting fuel and air charge.
