ABSTRACT:
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.
