Short answer . . . In the USA . . . MOSTLY NO.
Detailed answer . . . Federal Law prohibits tampering with emission control systems on emission control regulated engines . . . however on engines not regulated, usually those before 1974 then YES.
There are also some engines which have Exemption Executive Orders which would allow the use of it.
You could also apply for a waiver yourself if you are sure the manner in which it is used does not increase emissions in anyway, and if you are a franchisee we can help with that.
If you are an OEM manufacturer or re-manufacturer of the engine, you could create an engine family modification - and that is a complicated process, but we could also help with that.
Simply putting an older engine in a newer vehicle will not get around the law and and is unlawful.
On any device which is not regulated, that may not indeed be an engine strictly that uses Natural Gas or Propane, generally yes,

I see Hydrogen products, can I use these on my car ?? See ALSO our TOS at https://bigbay4bestbuys.com/content/terms-service-andor-use
The answer is an engineering one. It also depends on where you are - in a cold climate or always in a warm climate where no freezing occurs. You can use a cold weather hydrogen generator anywhere - and it generally can use any feedstock, but a warm weather PEM pure gas generator MUST use de-ionized or distilled water and connot be allowed to freeze.
You cannot convert or tamper with the OEM fueling system but you can supplement or piggy back with hydrogen so long as it it a parallel system that does not hinder the OEM system. Theoretically at the high end you can put on a complete fueling system and simply disable or "turn off" the OEM system. Create an account by purchasing our Gashole Plugged Video and ask in the notes and provide the VIN to us or other engine information.
The reality is for a car there is likely to be no room for the equipment, while truck and SUV vehicles or larger usually do.
