Foo - If one attached an O3 generator to their air intake

What would the results be?

A lot of ozone being sucked into their engine.

As I recall, ozone is unstable, it takes an input of energy to keep it together. UV light is just right for this task. That's why we find it in the upper atmosphere.

That being said, thermodynamics tells us that when ozone splits it would release some energy.

By contributing energy to keep ozone together, less of the UV energy reaches us, keeping most of us skin cancer-free

I believe the ozone would rapidly decay before it reached the combustion chamber, leaving diatomic oxygen to do its normal job.

I agree with MotoVincere's analysis.

It would more than likely require more energy than you would potentially gain.

From Wikipedia:

Ozone can be used for combustion reactions and combusting gases in ozone provides higher temperatures than combusting in dioxygen (O2). Following is a reaction for the combustion of carbon subnitride:

3 C4N2 + 4 O3 → 12 CO + 3 N2

Provides higher temps, huh? That makes the engine run more efficiently, if you can design the engine to run with the higher heat.

Instead of going vroom vroom, it would go vrooooom vrooooom.

Thermodynamics, dude.

0. You must play the game.
1. You can't cheat.
2. You can't win.
3. You can't even break even.

An ozone generator uses a lot of electricity to generate that ozone. You cannot get better economy by running a chemical reaction that an analysis allowed by Hess's Law tells you ultimately gives you the same balanced reaction as before, but with another one going forward and backward just for kicks. That extra reaction (O2 to O3 and back) cannot be done energy-free if done in a finite amount of time. (No reaction can.) This is a losing proposition for fuel economy.

But what if he installs a nitrogen filter? :p :D

I just want to know what the effects are? How would an engine react to being fed O3 all day?

Higher combustion temperatures will affect engine timing. If the timing isn't adjusted appropriately, you'll end up either carbonizing or gunking your pistons/cylinders.

Question: Would ozone combustion also change the fuel octane requirements by altering the compression via the increase in combustion temperature?

Haven't looked it up, but what's the density of O3? Would you have to suck more fuel in, or would you automatically get higher compression due to the separation of the O3 into O2 when it first begins to react?
