摘要： An internal combustion may include a cylinder having a first combustion chamber at one end and a second combustion chamber at an opposing end, first and second cylinder heads located at an end of the first and second combustion chambers, respectively, and a double-faced piston slidably mounted therein. The piston may be configured to move in a first stroke that includes an expansion stroke portion and a non-expansion stroke portion. The engine may further include first and second piston rod portions extending from opposite faces of the piston. A recess in the piston rod portions may be configured to communicate gases between a combustion chamber and locations outside the cylinder. There may also be a chamber surrounding the first or second piston rod portion, the chamber configured to be supplied with gas and the chamber being isolated from the first combustion chamber and the second combustion chamber.

摘要： An engine can include at least one piston, a block, a fluid delivery system, and an output shaft. The block can define at least one cylinder. The piston can be received in the cylinder. The piston can be operable to reciprocally move rectilinearly while positioned in the cylinder. The fluid delivery system can be operable to communicate air and combustible fuel to the cylinder. The piston can be operable to compress the air and combustible fuel. The output shaft can be driven in motion by the piston and extend beyond the block to a distal end. The output shaft is limited to rectilinear movement.

摘要： A high order of thermal efficiency is achieved in a steam engine or steam expander having a piston clearance that approximates zero together with a negligible amount of compression, such that pressure in the clearance volume approximates ambient pressure, i.e. atmospheric or condenser pressure as the case may be at the end of the piston return stroke when the clearance is essentially zero and constitutes a new engine apparatus and Rankine operating cycle that can be referred to as “zero clearance with zero compression”. The steam admission valve assembly can be operated either automatically responsive to piston contact or by means of a cam shaft or electrically by means of a solenoid. A normally open exhaust valve permits residual steam to be exhausted through the piston return stroke, closed by the piston or cam then held closed by a fresh charge of steam.

摘要： An internal combustion engine includes an annular or ring-type cylinder and piston therein; exhaust ports from the cylinder lead to an afterburner reactor situated generally medially of the annular cylinder; the exhaust gases are further burned within the afterburner section; to further reduce pollutants during the afterburning process, additional air is pumped into the afterburner section as by the ring piston due to its special configuration enabling it to accomplish, for example, triple functions such as: (a) to act as a power transmitting means, (b) to act as a pumping means to supply the engine's combustion chamber with scavenging air and/or an air-fuel mixture, and (c) to act as an air pumping means to supply desired quantities of ambient air into the afterburner section even in timed intervals with a constant predetermined pressure and predetermined quantities in order to thereby maximize the degree of control of the temperature generated in the afterburner and thereby more nearly fully oxidize the unburned fuel residues entering the afterburner. The ring piston is so constructed that it can be operatively connected to an output shaft as through the use of only a single crank, single connecting rod and wrist pin. Further, to extract a considerable amount of energy from the waste exhaust gases leaving the afterburner, a power turbine is provided which is within the exit path of the exhaust gases. The power turbine is conveniently incorporated as into the engine head and the turbine output shaft is either geared by reduction gear means to work in unison with the output crank shaft, or the turbine shaft rotates at an independent speed and is geared to drive (some or all of) the engine and/or vehicular accessories.
