One of the major problems in any engine is NOx. If we could solve this problem with a cheap and easy solution then we could go back to lean burn engines and diesels would be able to get way better efficiencies than they do today.
One idea I had (ya, I'm no scientist) was to filter out the nitrogen from the air and then replace it with the CO2 and water vapor from the exhaust. But I found two major problems.
- Finding a way to filter out all that nitrogen would take way too much energy making the engine very inefficient.
- N2 lends itself to efficiency as it has a higher specific heat ratio than CO2 or H2O vapor.
If only we could cheaply run our engines on bottled helium and oxygen...
