I've been thinking again so bear with me. To elliminate emissions all you have to do is connect the tailpipe to the intake.
What would happen if you connected the exhaust pipe to the intake?
You would have no emissions because the combustion cycle would be a closed system. But would the engine run? Or course not because it would run out of oxygen. But what if you pumped in oxygen and then took out carbon clumps? If you ran the engine on hydrogen you wouldn't have to deal with carbon clumps only water drops.
If this works I declare Patent Pending.
