ABSTRACT:
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.
