I have already done this.

However, Ozone generators are usually of the corona arc discharge type. They suffer from degraded performance if air humidity increases. Producing dry air in large enough quantities is a challenge otherwise the ozone generator delivers highly variable results depending on the weather!

Considering a higher air humidity level often leads to a better fuel efficiency while also decreasing NOx, it doesn't seem so bad at all. Eventually, if enough moisture is taken out of the air before it goes through the Ozone generator, it may also be repurposed for water injection.

I have 2,

one 220V and one that runs on 12V

Was thinking of putting the 12V one in to the air intake.

I guess it would be more efficient than attempting to run the 220V one through an inverter. But anyway, what are their outputs and on which vehicle are you willing to try?

Why is one more efficient than the other? They both will require voltage step up for the corona. Matching input voltage to the unit is where the efficiency will be.

I don't know. I am not so familiar with Ozone generators.

There is no power advantage for the devices.

Whether 12v or 120v. There is an efficiency loss for the DC to AC inverter to use the 120v unit.

Ozone generators have a simple high voltage/low current circuit that can be configured to run on DC or AC.

Well technically, in the stepup transformer, the smaller ratio is considered to be more efficient because of saturation so 120 v might use less watts, wasn't adding the 12 to 120 stepup.

I forgot the math to calculate the Watts output in proportion to Amperes, Ohms and Volts, but sometimes transformers are pointed out to be quite inefficient overall, even though under some circumstances they may actually fare better.

The efficiency differences are negligeable.

For what is intended (automobile powered ozone generation) either will work. The efficiency difference is under a watt.

The trick is providing a steady stream of relatively dry air.

I work with bio-medical ozone devices and we simply run an adsorption oxygen generator followed with a condensate scrubber and topped off with a polymer absorption canister like those beads you find in some food packets to absorb moisture.

You don't need a huge amount of ozone. Simply calculate your air consumption at cruise and translate into molar mass. Then, you just need an equivalent of 40 parts per million to greatly accelerate combustion processes. Even concentrations in parts per billion have measurable effects.
