Abstract
A six-stroke cycle engine fires a fuel charge for a first power stroke, the exhaust gases being directed to a thermally insulated jacket surrounding the cylinder and having fins and/or baffles to recover heat from the gases and conduct the heat to the inner cylinder wall for converting injected water into steam for a second power stroke. The fins and/or baffles in the jacket also function as a muffler for the engine.
Claims9
In a cyclic engine having at least one piston and cylinder provided with means for introducing and firing a fuel-air charge for a first power stroke, means for exhausting hot products of combustion from said cylinder and means for injecting steam/water into said cylinder for a second power stroke, the improvement comprising:
- means defining a chamber surrounding said cylinder, said means for exhausting products of combustion from said cylinder being arranged to direct said products into said chamber;
- means for conducting heat from said products in said chamber to the inner surface of said cylinder, and
- an exhaust passage from said chamber.
A cyclic engine comprising:
- a. a cylinder,
- b. a piston in said cylinder,
- c. means for introducing a charge into the engine for a first power stroke,
- d. means for exhausting hot products of combustion from said cylinder,
- e. means for providing steam in said cylinder for a second power stroke,
- f. a chamber positioned substantially coaxial with said cylinder,
- g. said exhausting means being arranged for directing the hot products into said chamber,
- h. means for conducting heat from the hot products in said chamber, and
- i. an exhaust passage in said chamber for exhausting the hot products.
