ABSTRACT:
A high temperature, high pressure, four-cycle piston engine having two companion cylinders or multiple pairs of companion cylinders connected by a transfer valve or valves and working together to complete the four-cycle operation. The internal combustion of fuel and air in the ceramic cylinders is utilized as a means of producing heat and this heat is used to generate superheated steam by cyclicly injecting water into the hot power cylinders, with each power cylinder serving as a steam boiler. Ceramic pistons in the power cylinders use the power of the expanding steam to do useful work and operate to exhaust all gases after each power stroke. The engine can be adapted for both compression ignition and spark ignition operation.
