Look For Relevant Emissions Durability Period and Air Index
Information On Your Small Off-Road Engine Emissions Label
Engines that are certified to meet the California Air Resources Board
(CARB) small off-road 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.
Briggs & Stratton engines are certified to meet the United States
Environmental Protection Agency (USEPA) Phase 2 or Phase 3
emissions standards. 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.
For engines less than 225 cc displacement.
Category C = 125 hours
Category B = 250 hours
Category A = 500 hours
For engines of 225 cc or more displacement.
Category C = 250 hours
Category B = 500 hours
Category A = 1000 hours
