This patent is from 1999. I would expect such devices are already in play and if not why not.

Device for reducing toxic wastes of diesel fuel 
ABSTRACT
This invention relates to a device for reducing toxic wastes of diesel fuel and more particularly, to a novel-type device for reducing toxic wastes of diesel fuel. The device of this invention, being equivalent to a pretreatment device, is mounted to the surface side of a fuel feed port at a diesel internal combustion engine so as to activate molecules in diesel fuel and their molecular movement. In particular, with a view to effective induction of electromagnetic wave and magnetic field, some supplement equipments such as magnet (6a, 6b, 6c), ceramic pole (7a, 7b) and coil (8) are arranged on the device of this invention and based on this fabrication, perfect combustion conditions of diesel fuel may be provided in such a manner that same physicochemical changes are offered to diesel fuel, passing through the fuel feed port. Thus, the device of this invention has advantages in that a) after diesel combustion, the release of toxic substances in exhaust gas may be significantly inhibited, and b) fuel consumption may be further improved....
