    Abstract: The use of porous materials in the dead space of reciprocating engines is described. The porous material can be used to condition the cylinder gases. In addition, the porous material may include a catalyst for driving chemical reactions. The catalytic process occurs on the porous material, not on the cylinder walls. The engine parameters (number of cycles, number of strokes per cycle, compression ratio, engine speed, cylinder volume, valves timing, gas composition, pressure and temperature) are adjusted to optimize gas compression or chemical reactor performance.

    Abstract: An internal combustion engine includes a piston disposed within a bore and moveable in a reciprocating motion within the bore along a central bore axis. The piston includes an axial end surface that defines a combustion chamber having a plurality of annular recesses recessed into the axial end surface of the piston. One of a plurality of valves is disposed opposite each of the plurality of annular recesses of the combustion chamber. Each of the plurality of annular recesses is axially aligned with a head of one of the plurality of valves and is sized to receive an outer perimeter of the head therein to provide clearance during valve overlap, between the axial end surface of the piston and the head of the valve, when the piston is disposed near a top dead center position.

    Abstract: A combustion chamber for an internal combustion engine, adapted to promote induction air flow. The combustion chamber has a bulge located near an intake valve head. The bulge projects away from the piston and forms that part of the combustion chamber farthest from the piston. Slope of the walls of the bulge is greater than the angle of the head of the intake valve relative to the deck of the engine block, in engines having separate cylinder heads. The bulge is curved so as to make seamless transition with the cylinder wall at that portion away of the bulge which is distant from the intake valve.

    Abstract: In an internal combustion engine a piston and a cylinder head defining a cylinder with a blind end thereatop are formed in a conical configuration. The piston compresses charges of an air/fuel mixture in the blind end of the cylinder, whereupon ignition of the fuel is initiated. Combustion of the fuel proceeds first from the region of ignition in the blind end of the cylinder and then along the interstitial space between the diverging conical walls of the cylinder head and piston. The expanding products of combustion squeeze the piston from the top and the sides, thereby transferring power smoothly and directly to the piston. The progress of combustion spreads equally both downwardly and radially outwardly from the axis of the piston, thereby providing an efficient transfer of power with a high fuel economy.

    Abstract: A combustion process and apparatus for a spark ignited air compressing internal combustion engine with direct injection of the major portion of the fuel onto the wall of the combustion chamber provided in the piston in the form of a body of revolution, according to which a rotary motion is imparted upon the inflowing air in such a way that the fuel is gradually released from the combustion chamber wall and mixed with the air in the form of vapors. The injection nozzle is positioned in the cylinder head near the combustion chamber throat while the ignition device extends into the combustion chamber at the top dead center position of the piston. The fuel is injected onto the combustion chamber wall by means of a jet from which individual small fuel particles are detached which are immediately mixed with the air on being emitted from the injection nozzle opening. The small amount of combustible mixture formed by the fuel particles detached from the fuel jet and not yet conveyed by the centrifugal forces onto the wall is toward the end of the injection phase ignited close to the injection nozzle opening by the ignition device. The thus initiated combustion propagates in the direction of the revolving air across to the fuel film existing on the wall of the combustion chamber in the piston. Subsequently the main combustion takes place in conformity with the progress of the mixture of the fuel vapors generated in the wall region with the air circulating in the combustion chamber.
