A vehicle emissions control system has been conceived and developed with the goal of reducing emissions to significantly less than the 1976 Federal standard of 0.41 g/mile HC, 3.4 g/mile CO, 0.4 g/mile NOx. This system utilizes known emission control methods in a unique sequence.The Reverter system utilizes enriched carburetion and relies on three stages of operation: limited (or partial) oxidation of the exhaust gas without the aid of a catalyst, chemical reduction of nitric oxide aided by a catalyst in the presence of a CO rich atmosphere, and final and complete oxidation of the exhaust gas without the aid of a catalyst. The system has been designed with special provisions for durability, high temperature controls, and catastrophic failure protection. The system can operate on commercially available high or low leaded fuels.The Reverter system is discussed from its beginning to its present phase of development. Required operating parameters of the system are described, such as air management and fuel requirements. Investigations of required system materials indicate the possibility of using both high temperature alloys and glass ceramics. Also described are subsystems which will control the operating temperatures under various engine load and speed conditions including catastrophic failure protection for the emission control system.Efforts are outlined to refine the total system further. It is presented in terms of the development work necessary to lower system operating temperatures, thus reducing the associated fuel economy penalty and increasing the system's physical durability.
