Research links (and some thoughts) on Ozone in ICEs

Just doing a bit of research on the effect of Ozone on combustion:

O3 means more oxygen in the same volume of gas. Thats good.
Apparently Ozone breaks down to atomic O and O2 during compression and reacts with HCs, forming radicals etc, in ways beneficial to flame speed and more complete fuel burn etc and allowing leaner mixtures etc.

That's all good, but if the 'Ozonator' itself uses more power than it adds and/or lowers the power to weight ratio of the car as a whole; it's not worthwhile.
That's why this post is here... for the mean time...


Effect of Ozone on Combustion of Compression Ignition
Engines

The effect of ozone addition to the intake air on combustion in compression ignition engines was examined using a Diesel CFR engine.
The experimental results show that ozone addition improves the combustion haracteristics.
Addition of 500 ppm ozone, for example, increases cetane number by 2 to 4 and lowers the compression ratio of the ignition limit by 1 to 2, depending upon the kind of fuel used and the operating conditions. Regarding exhaust
emissions, a small decrease in CO, hydrocarbons, and particulates and a small increase in NO x have been observed
with ozone addition under the fixed operation condition.

... A fraction of the oxygen that passes through the ozonizer is converted into ozone by the following reaction:
3 0 2 = 2 0 3 - 68 kcal.

...Under the operating conditions shown ...the intake air flow is about 250 L/min.
Therefore the energy necessary for the production of 1000 ppm ozone is about 25 W...
Although the highest ozone concentration in the present experiment is 1000 ppm, an Ozonizer of the order of several hundred watts is necessary because of the inefficiency of ozone conversion process.

...Several percent of the output
power must be used for 1000 ppm ozone
production at present, but this rate will be
lowered by the improvement of ozonizer
without difficulties..."

Of so Ozone is a good idea.
The power spent on Ozone production is worthwhile I
IF
The "Ozonizer" is way more efficient than the one they had..!

Hmmm... so where or how does one get or build said efficient "Ozonizor"???

(and... if you're creating ions in air you that want to get INTO an engine;
can you add magnets and 'MHD turbo' that 'Supa-O-Air' into the engine! )

I'm not surprised about the decrease on CO˛, HC and particulate matter, or the increase on NOx. Maybe if a larger amount of Ozone could replace some larger amount of the fresh air at the intake charge, considering there is more Nitrogen in the air than Oxygen, NOx wouldn't be so greatly impacted. Either this, or resorting to some supplemental injection of a volatile fuel, which would also more likely lead to a substantial performance improvement.

Ozone’s impact on combustion is fascinating—especially the potential for increasing flame speed and improving fuel efficiency. But yeah, the key issue is whether the energy used to generate ozone outweighs the benefits. If ozonizers become significantly more efficient, this could be a game-changer for ICEs. Also, combining it with MHD tech to "supercharge" the air could lead to some interesting results.

I THINK the efficiency of an 'Ozonator' is all about charge density between the electrodes paniwew.

ie: As the PD between the electrodes is X volts; the only way to increase the charge density in one electrode vs the other is to 'sharpen' one and round the other.

Most such products are just stamped out of metal, leaving a lot of efficiency on the table.

Here's more or less what I'm thinking, just sharper and rounder/polished:


NB the similarity to intake trumpets or bell mouths..!

Then we use resonant circuits to greatly increase the efficiency of radio transmitters etc.

Here's a post on this being Cool Looking! But it does gives one ideas!
