ABSTRACT:
An internal combustion engine utilizes a combustion cylinder formed in part of material which can withstand high temperatures in conjunction with a displacement or power piston having a ringless section capable of withstanding high temperatures and being backed up by a relatively low temperature lubricated ringed piston section. Means to inject fuel and water into the combustion chamber is provided along with means to charge the combustion chamber with air and to exhaust the combustion chamber near the end of the power stroke.
