Look For Relevant Emissions Durability Period and
Air Index Information On Your Engine Emissions Label
Engines that are certified to meet the California Air Resources Board
(CARB) Tier 2 Emissions Standard must display information
regarding the Emissions Durability Period and the Air Index. Briggs &
Stratton makes this information available to the consumer on our
emissions labels. The engine emissions label will indicate certification
information.
The Emissions Durability Period describes the number of hours of
actual running time for which the engine is certified to be emissions
compliant, assuming proper maintenance in accordance with the
Operating & Maintenance Instructions. The following categories are
used:
Moderate:
Engine is certified to be emissions compliant for 125 hours of actual
engine running time.
Intermediate:
Engine is certified to be emissions compliant for 250 hours of actual
engine running time.
Extended:
Engine is certified to be emissions compliant for 500 hours of actual
engine running time. For example, a typical walk-behind lawn mower
is used 20 to 25 hours per year. Therefore, the Emissions Durability
Period of an engine with an intermediate rating would equate to 10
to 12 years.
Certain Briggs & Stratton engines will be certified to meet the United
States Environmental Protection Agency (USEPA) Phase 2 emissions
standards. For Phase 2 certified engi nes, the Emissions Compliance
Period referred to on the Emissions Compliance label indicates the
number of operating hours for which the engine has been shown to
meet Federal emissions requirements.
Engines that are certified to meet the California Air Resources Board
(CARB) Tier 2 Emissions Standard must display information
regarding the Emissions Durability Period and the Air Index. Briggs &
Stratton makes this information available to the consumer on our
emissions labels. The engine emissions label will indicate certification
information.
