Manufacturers must use a standardized system for identifying their individual engine families. The system described was developed by the Environmental Protection Agency (EPA) in 1991 to meet new regulatory requirements for 1994 and later model years.





The ENGINE FAMILY name and EVAPORATIVE FAMILY name consists of 12 characters each.

Both the engine family name and the evaporative family names are listed in the box on the emission decal, in the area marked as engine/evaporative family information. The first line is the spark plug information. The second line contains the engine size and the evaporative family name (12 characters).
