Abstract:
1. A reciprocating internal combustion engine having (a) one or more cylinders each with at least one piston, each cylinder having a cylinder wall, (b) one high-pressure motor for each cylinder, each high-pressure motor integral with and attached in direct contact with its respective cylinder wall, (c) a crankshaft from which conventional mechanical power is derived, and (d) two-stage exhaust apparatus having in each cylinder (i) at least one exhaust port to release low-pressure residual exhaust gas directly to the atmosphere and (ii) a jet port configured to open to release high-pressure exhaust gas to its corresponding high-pressure motor, the jet port opened only by being uncovered by the position of the piston in the cylinder, jet-port volume being sized to prevent expansion and cooling of exhaust gases released to the high-pressure motor, the exhaust-gas release being prior to exhaust-port opening in order to recover additional power from the engine non-parasitically, without loss of mechanical power from the crankshaft.
