Here is the basic idea: - An oxygen concentrator draws air from behind the radiator (or wherever you want)
- OC will compress the air and create a near 100% oxygen content which will be directly injected into the cylinder
- At the same time, fuel will be directly injected
- During the compression stroke, the pressure from the piston will force the oxy/gas to ignite
- Exhaust (which I think will be hotter than a standard engine) will run a turbo
- Turbo runs a generator
- Power from generator supplies battery
- Battery powers OC
Some issues:
- I doubt the turbo will be able to supply all the power to the concentrator, but hopefully it can and maybe a little bit more.
- How to "vent" the exhaust from the cylinder, other than a standard exhaust valve?
- Is water injection still necessary?

The main hindrance will be the rate of production of your oxygen concentrator. Medical devices that use pressure swing adsorption can produce up to 10 L per minute of near pure oxygen. However, they are quite large in physical size and will require wall power levels to run ( hundreds of watts ). This small amount of oxygen could run a small single piston engine but that engine will not have the exhaust energy to power a substantial turbo
