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

(page 13) for additional information.

* The power rating of the engine indicated in this document is the net power
output tested on a production engine for the engine model and measured in
accordance with SAE J1349 at 3600 rpm (net power) and 2500 rpm (max.
net torque). Mass production engines may vary from this value. Actual
power output for the engine installed in the final machine will vary
depending on numerous factors, including the operating speed off the
engine in application, environmental conditions, maintenance, and other
variables.
