Regenerative intensifier systems that can receive fluids from landfills, anaerobic digesters, wastewater treatment plants, animal waste lagoons, swamp gas, decaying permafrost, and oceanic clathrate decomposition interchangeably with natural gas and other available fuels and substances and provide suitably conditioned fuel for operation of an engine, fuel cell, or other industrial and/or chemical processes. Alternatively, gases collected from landfills, waste digesters, bakeries, breweries, ethanol plants, calciners, power plant stacks, electrolyzers, and/or natural gas that may be delivered at relatively low pressures can be converted to high pressure and/or high purity constituents to enable efficient utilization as a transportation fuel and/or industrial feedstock or chemical plant reactant.

1. An internal combustion engine, comprising: a cylinder that forms a combustion chamber, wherein the cylinder includes an injector disposed therein having a flow valve and wherein the cylinder includes an exhaust valve having a flow diverter valve;an intensifier in fluid communication with the combustion chamber;a pressure tank in fluid communication with the combustion chamber and the intensifier; anda four way valve connected between the pressure tank, the intensifier, and the combustion chamber, wherein the valve is operative to control multi-directional fluid flow among the pressure tank, the intensifier, and the combustion chamber via the flow valve and the flow diverter valve. 2. The engine according to claim 1, further comprising a glow plug disposed in the cylinder, wherein the four way valve is operatively coupled with a flow valve of the glow plug. 3. The engine according to claim 1, wherein the intensifier includes: an intensifier piston disposed in a corresponding intensifier chamber having an associated intensifier chamber inlet and outlet; anda drive piston connected to the intensifier piston and disposed in a corresponding drive chamber having an associated drive chamber inlet and outlet. 4. The engine according to claim 3, wherein the drive chamber inlet is connected to a conduit extending between the pressure control valve and the pressure tank. 5. The engine according to claim 4, wherein the drive chamber inlet is connected to a selector valve connected to the conduit. 6. The engine according to claim 5, further comprising a fuel injector disposed in the cylinder. 7. The engine according to claim 6, wherein the drive chamber outlet is connected to the fuel injector. 8. The engine according to claim 3, wherein the intensifier chamber inlet is in fluid communication with the drive chamber inlet. 9. An internal combustion engine, comprising: a combustion chamber;a fuel injector disposed in the combustion chamber;an exhaust valve in fluid communication with the combustion chamber;a pressure tank in fluid communication with the combustion chamber;a four way valve connected between the pressure tank, an intensifier and the combustion chamber via the fuel injector and exhaust valve, wherein the four way valve is operatively coupled with the fuel injector and operative to control a fluid flow between the pressure tank, intensifier and the combustion chamber; andwherein the intensifier is in fluid communication with the combustion chamber, including: an intensifier piston disposed in a corresponding intensifier chamber having an associated intensifier chamber inlet and outlet; anda drive piston connected to the intensifier piston and disposed in a corresponding drive chamber having an associated drive chamber inlet connected between the four way valve and pressure tank. 10. The engine according to claim 9, wherein the intensifier piston has a working diameter and effective area selected from at least one of smaller, equal, and larger than a working diameter and effective area of the drive piston. 11. The engine according to claim 9, further comprising an inlet check valve and an outlet check valve associated with the intensifier chamber inlet and outlet, respectively. 12. The engine according to claim 11, wherein the drive chamber includes an associated drive chamber outlet connected to the fuel injector. 13. The engine according to claim 11, wherein the drive chamber inlet is connected to a conduit extending between the pressure control valve and the pressure tank. 14. The engine according to claim 13, wherein the drive chamber inlet is connected to a selector valve connected to the conduit. 15. The engine according to claim 13, wherein the intensifier chamber inlet is in fluid communication with the drive chamber inlet. 16. A method of intensifying the pressure of a fluid using an internal combustion engine having a combustion chamber, the method comprising: supplying the fluid from a supply source to an intensifier including a drive piston operative to act on an intensifier piston;pressurizing a working fluid in the combustion chamber;conveying the pressurized working fluid directly from the combustion chamber to the drive piston wherein the working fluid moves the drive piston and intensifier piston, whereby the intensifier piston intensifies the pressure of the fluid;closing intake and exhaust valves in fluid communication with the combustion chamber; andopening a flow director valve of a fuel injector in fluid communication with the combustion chamber to allow selected gases to be delivered to the supply source, wherein the supply source is a storage tank. 17. The method according to claim 16, wherein the drive piston has a drive diameter and effective area the intensifier piston has an intensifier diameter and effective area selected from at least one of less, equal, and larger than the drive diameter and effective area. 18. The method according to claim 16, further comprising preventing the fluid from returning to the supply source. 19. The method according to claim 16, subsequent to conveying the pressurized working fluid to the drive piston, conveying the working fluid to an injector on the internal combustion engine.
