An energy conversion cycle for an internal combustion engine and an internal combustion engine capable of carrying out the process to produce work, the process characterized by the steps of forming fuel and air charges having fuel to air proportions varying from stoichiometric at full engine power to excess air at less than full engine power conditions; increasing by compression the density and activation of the molecules of the charges supplied to a variable volume working chamber in which fuel and oxygen in the air are reacted to produce thermal potential; controlling fuel and air distribution in the working chamber so that the excess air portion of each charge is located in an air reservoir chamber that is separated from the reaction area by an open partition area separating the working and air reservoir chambers; and through the partition area, controlling availability of oxygen in the working chamber during the reaction while permitting the oxygen to be activated in a specific manner by molecular interaction with the reaction process itself across the partition area to the extent that pressures in the working and reservoir chambers are equalized during the reaction. Diffusion of molecules of activated oxygen across the partition is controlled and such molecules sustain the reaction after its initiation in a manner that the reaction is carried out with the proportion of fuel to oxygen always on the excess fuel side of stoichiometric in accordance with requisites for rapid reaction of the fuel with oxygen. The engine is characterized by an arrangement of mechanical elements and charge forming devices including moveable pistons for varying a working chamber volume; means for controlling distribution of the fuel and air so the total fuel portion of each charge is in the working chamber at initiation of each reaction with a sufficient quantity of air to insure a rapid rate of reaction between the fuel and oxygen; and means for distributing excess air of each charge in an air reservoir chamber separated from the working chamber by an open partition area having a special control function over the molecular interaction between the chamber and reservoir, such control function insuring that, during the useful work producing part of the reaction, the proportion of fuel to oxygen in the working chamber is maintained in a fuel "rich" condition. |
