Small ozone generating device, approx. 2x4x7", will create plenty of ozone to destroy residual carbons (monoxide & dioxode) exiting from catalytic converters into harmless oxides; with only oxygen exiting from tailpipe. We have the building plans & drawings, and will construct a functioning prototype for an individual or company that can market this device. It is a safe, (it destroys smog and
produces oxygen) small, (it will fit above the muffler & run off the alternator without affecting any of the vehicle's functions) versitile,
(will work on any type fuel) and inexpensive, per cost & operation!
