. . . that was tried by a team leading up to the AutoXprize. But, carrying enough pure oxygen around is a problem they could not overcome.
The advantages are numerous. You can shrink your engine and still produce the same amount of power. You do not have to run the engine cool since nitrogen is not present to produce the pollutants. Your thermal efficiency is increased.
Oxygen concentrators can be used but they are large and cumbersome for the size of the engine. They are being tried with super-critical CO2 turbine cycles for utility scale power production.
