AIR INDEX
To show compliance with California emission regulations, a hangtag
has been provided displaying the Air Index level and durability period
of this engine.
The Air Index level defines how clean an engine’s exhaust is over a
period of time. A bar graph scaled from “0” (most clean) to “10” (least
clean) is used to show an engine’s Air Index level. A lower Air Index
level represents cleaner exhaust from an engine.
The period of time (in hours) that the Air Index level is measured is
known as the durability period. Depending on the size of the engine, a
selection of time periods can be used to measure the Air Index level
(see below).
