This solves two problems and creates one and a half, the ionizing input air idea inspired it. Basically, there are these gadgets called "air separators" marketed by Shell-DEA. It's a membrane filter that can be used to create pure nitrogen by filtering out oxygen and water vapor. There are similar
devices that do the same but produce oxygen. I am not sure how much energy it takes to drive air through these things but if you had highly oxygen enriched air it would increase combustion temperature and increase efficiency. If it were nearly pure O2, then there would be no nitrogen present to oxidize and there would be no NOx emmisions. The problem is not only the higher temperatures that the materials then have to take (high tech ceramics?), but the knocking of the motor. At running temperatures it is quite possible that gasoline would start burning directly after injection, or at least long before it should, so maybe other fuels would be better. Perhaps diesel, or even vegetable oil.

Good idea. I was just going to post an idea involving a tank of liquid oxygen, which would do the same thing. Sadly, it takes insanely low temperatures to create liquid oxygen, making your idea more realistic than mine. That gets my bun! |

Got a cite for the "Shell-DEA air separator" ? |
