Abstract

An internal combustion engine includes a moving piston within a combustion chamber that is temporarily divided into two zones when the piston is at and near its minumum volume position. Fuel is confined to a first zone where the fuel is ignited to generate combustion wave energy that drives gas within the second zone in Helmholtz resonance through a restricted passageway. Air from the second zone is periodically expanded into the first zone through the passageway to improve the combustion process in the first zone before the piston moves substantially away from its minimum volume position.
