Air hybrid engine with dual chamber cylinder

An air hybrid engine with dual chamber cylinder comprising:

• an upper chamber for combustion/exhaust and or for intake/compression;
• a lower chamber for intake/compression wherein;
• said lower chamber and or said upper chamber are used for energy recovery and or for supercharging an engine;
• an air storage tank having a first valve operated by an ignition key and a second valve operated by a brake pedal or by an electric controller of a vehicle;
• said lower chamber and or said upper chamber is located in an engine and or downstream of a transmission;
• said storage tank further includes a pressure relief valve that opens when a pressure within said storage tank exceeds a preset threshold;
• with a housing having a first cylindrical cavity and at least a second cylindrical cavity each said cylinder cavity has a piston that divides each said cylindrical cavities into an upper chamber and a lower chamber;
• at least one head on top of said upper cylindrical chamber for enclosing said cylindrical chambers;
• each piston each having piston rods extending perpendicular from a bottom of each piston;
• a low friction seal located on a bottom of each of said cylinders to allow sealed constrained linear movement of said piston rod(s);
• said separate piston rods are secured to an elliptical shaft to convert reciprocating rectilinear motion into rotary motion;
• an inlet and an inlet check valve on each of said lower chamber cylindrical cavities for bringing air into said lower chamber when said pistons are on an up stroke;
• an outlet and an outlet check valve on said lower chamber cylindrical cavities wherein compressed air is pushed out through said outlet and outlet check valve when said pistons are on a down stroke;
• said compressed air from a first lower chamber is transferred to a first upper chamber of the same and or a separate cylindrical cavity (ies), or to said air storage tank wherein said compressed air is used to supercharge said engine or for energy recovery during deceleration;
• said at least one piston has a piston rod extending in a fixed perpendicular relationship from a bottom of said piston and extending through a low friction seal in the bottom of said at least one cylinder;
• said piston operably slides with reciprocating rectilinear motion inside said at least one cylinder;
• said piston rod is secured to an elliptical shaft device, to convert reciprocating rectilinear motion into rotary motion between a bottom dead center location and a top dead center location of an engine shaft;
• a distance between said bottom dead center and said top dead center is equal to half of the distance of a major axis and a minor axis of said elliptical shaft and each piston stroke will turn said internal combustion engine at 90 degrees;
• said elliptical shaft device, shaft has an inside wall that pushes said at least one piston into said at least one cylinder and an outside wall that pulls said at least one piston out of said at least one cylinder;
• said elliptical shaft further having a lobe(s) for operating an exhaust valve and a lobe(s) for operating an intake valve, and
• said at least one piston rod has bearings that engage said at least one piston rod on said elliptical shaft.
