I find this interesting.
As I was the last engineer on the commercial Thermasan (Thetford - Ann Arbor, MI) program. We found the EPA's interference insurmountable. Many states already had laws that prohibited the modification of a vehicle exhaust system. So, unless the vehicle were shipped with the Thermasan unit installed, there was little possibility of aftermarket.
As far as no odor, at IC engine exhaust temperatures, that is hard to believe. We had to work very hard at controlling the injection rate to prevent the entire lab from an aroma of "roasted diaper".
Diesels are even worse. They do pump more air, but the exhaust flame temperatures are always lower.

I wish you well.
