Emission Control (Exhaust & Evaporative)
EPA 2010 and Later and/or C.A.R.B. TIER III
The emission control system for the engine is EM (engine modification) and, if the second to last character of the Engine
Family on the Emission Control Information label (sample below) is "C", "K", or "T", the emission control system is EM and
TWC (3-way catalyst). The fuel tank/fuel line emission control system is EVAP (evaporative emissions). Evaporative emis-
sions for California models may only be applicable to fuel tanks.
An Emission Control Label is located on the engine. (This is an EXAMPLE ONLY; information on label varies by engine
FAMILY).
PRODUCT EMISSIOn DURABILITY (EMISSIOn COMPLIAnCE PERIOD)
The 300 hour emission compliance period is the time span selected by the manufacturer certifying the engine emis-
sions output meets applicable emissions regulations, provided that approved maintenance procedures are followed as
listed in the Maintenance Section of this manual.
