Air Index
An Air Index Information hang tag/label is applied to engines
certified to an emission durability time period in accordance with
the requirements of the California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability
to compare the emissions performance of available engines. The
lower the Air Index, the less pollution.
The durability description is intended to provide you with
information relating the engine's emission durability period. The
descriptive term indicates the useful life period for the engine's
emission control system. See your Emission Control System
Warranty for additional information.
