Is there a market for an O2 output device that may eliminate a catalytic probem?

Question type: Maintenance & Repair

Before I start a costly Patent application I need to get opinions from the mechanics in this forum.
Most of us are aware of the importance O2's play in a cars operation and many mechanics look at the O2 as either good/bad .... in many cases the sensor is good but triggering an alarm due to the malfunctioning Cat.
FYI ... A cat is a High temp material that looks like a "HONEY-COMB" ..Platinum is sprayed by Plasma (Liquifies Metal for spraying) on the surface of the honey-comb ,,, unburned gas (Hydrocarbon) reacts  with red hot platinum and forces the unburned gas to combust ... thus the cat is always hotter at the discharge then the input side (at least 100 digress hotter)  Whew ... all that for my invention ... #2 O2 is looking for unburned gas ,,, if it see's it you get the alarm.  The reaction inside the O2 generates electricity and the typical output from a good Cat is around POINT 5 VOLTS or 1/2 volt
The voltage is read by the ECU and if it's too high/low  it adjusts the engine to run rich/lean to compensate.  ~~~~~~~~~~~~~ Here's the idea ... If a Cat gets coated it will not react causing the O2 trigger,  My device will adjust an O2 output so the engine will clean a coated Cat  and when the cat returns to normal it will again trigger the O2 so the adjustment is no longer needed.
Some may say ..."why not just put a resistor to adjust the O2?"  Answer is /// it won't work on most cars because the O2's output is actually like a battery and is "isolated" from the Cars electrical system.  If you use the cars electrical system then you could introduce 12 volts into the ECU and wind up with "Crispy Critters" /// plus the brilliant engineers want the ECU to see a varying signal ... not a straight 1/2 volt  (same concept in the anti-theft system ... that's why it can't be jumped)
My device use 2 plugs and goes in-line with the O2 ....

people will pay for something that they tink will fix there problems a new cc costs on average $400 so if it cheaper than that the people will go for it its all in the advertisments

This is primary for mechanics because it has other uses too .. like it will check the O2 heaters, voltage and such. It should sell for much less than $100


The mass air sensor measures the amount of air entering the engine and adjusts the fuel to match. Not sure if your invention could be incorporated into electronic engine management or not or what the benefit would be. If cars had a barometric sensor then the exact amount of O2 entering the engine could be calculated based on the volume of air entering along with the density.


Based on your input .. I'm afraid you don't have a clue regarding what an O2 sensor does ... Perhaps before you give advice on something .. you should know the subject matter.
