Abstract

A six-stroke cycle engine burns an air-fuel charge for a first power stroke, the exhaust gases being directed to a heat regenerator located in a vapor heating chamber. A second power stroke is produced by injecting fluid directly into the heat regenerator, for generating a second power stroke with the expanded vapor, using the same engine reciprocating mechanism.
