Emissiiis Information
Engines that are certified to meet the
California
Air Resources
Board (GARB) Tier 2 Emission Standards must display
information regarding the Emissions Durability Period and Air
Index. The engine manufacturer makes
this
information
available
to the consumer on
emission labels. The engine
emission label will indicate certification information.
The Emissions Dyrability 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 emission
compliant
for
125
hours
of
actual
engine running time.
intermediate; Engine is certified to be emission compliant
for
250
hours of actual engine running time.
Extended:
Engine is certified to be emission 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 engines will be certified to meet the United States
Environmental
Protection Agency (USEPA)
Phase
2 emission
standards. For phase 2 certified engines, 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 emission
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:
Category C = 250 hours
Category B =
500
hours
Category A = 1000 hours
