CARB And EPA Emissions Control Information
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 “B”, “C”, “K”, or “T”, the 
emission control system is EM and 
TWC (3-way catalyst). The fuel tank/

EVAP (evaporative emissions). Evaporative emissions for California models are 
only applicable to fuel tanks.
An Emission Control Label is located 
on the engine. (This is an EXAMPLE

Product Emission Durability 
(Emission Compliance Period)

compliance period is the time span selected by the manufacturer certifying the

approved maintenance procedures are followed as listed in the Maintenance
