Emissions Durability Period and Air Index
Information On Your Engine Emissions Labe!
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 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 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.
The
Air Index is a
calculated
number describing
the relative
level
of emissions
for a
specific engine family. The lower the
Air Index, the cleaner the engine. This information is
displayed in graphical form on the emissions label.
Emissions Compliance Period On Engine
Emissions Compliance Label
After July
1
,2000 certain
Sears 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, В = 250
hours
and A = 500 hours. For engines of 225
cc
or more.
Category
C
=
250 hours, В
=
500 hours and A
=
1000 hours.
This
engine
has a
moderate
rating with and Air
Index
of 3.
The EPA Emissions compliance period is Category C. The
displacement of this engine
is
158 cc.
Below is a generic representation of the emission label
typically
found on a certified engine.
