ABSTRACT:
An internal combustion hydraulic engine for use in motor vehicles and the like comprises at least one piston having a first piston head and a second piston head; a first or combustion cylinder at least partially surrounding the first piston head for receiving fuel and air; an igniter for inducing combustion of the fuel-air mixture in the first cylinder; and a second or hydraulic cylinder at least partially surrounding the second piston head for receiving fluid such that the action of the combustion of the fuel on the first piston head induces the second piston head to pressurize the fluid in the hydraulic cylinder. Preferably, the pressurized fluid communicates through a high pressure tank with a hydraulic motor to convert fluid pressure into rotational power.
