Maybe I can do that with the Halon system from my race car I'm parting out. It basically removes the O2 from the air. Only problem would be no room to put it anywhere. It is even cable operated.
I'm not sure about halon, I suggested CO2 because it doesn't leave residue. If you use halon do you end up having to clean up a mess left from discharging it. If so, I'd not use it unless you plan on a full rebuild immediately following the injection into the intake.
AFAIK, it is a liquid which turns to gas, which absorbs oxygen, no residue.
Halon would be an excellent choice. It is used in basically all aviation fire extinguishers (including the fire bottles for engines). It is really good stuff and is about 3x more effective than the same amount of CO2.
