Abstract
An engine has a piston with plural end faces that compresses combustible mixtures on both sides of the piston and in each end of a closed cylinder containing the piston. The cylinders are fully enclosed with provision for a power takeoff rod to pass therethrough. Each instant closed cylinder with the dual end faced piston can produce power with each and every single stroke of its reciprocating travel. Multiple power generating methods are disclosed, as is a Hybrid type engine utilizing at least two of the multiple methods in a plurality of cylinders.
Claims41
A power stroke engine, comprising essentially:
- at least one cylinder;
- said at least one cylinder closed at both ends;
- at least one opening for a piston rod at a minimum of one of said ends;
- at least one piston;
- said at least one piston within said at least one cylinder;
- said at least one piston having two end faces;
