The California Air Resources Board has compiled a searchable database for verified diesel emission control systems to assist the users find a retrofit device that is potentially verified for their on-road engine.

This database is searchable by device name, engine family name, or a less specific search by engine model year, manufacturer, and displacement. It currently includes California certified 1992 and newer on-road engines, and 1996 and newer off-road engines.

Additional model years will continue to be added, and the database will be updated on a regular basis.
