Purpose. The purpose of this test is to
determine how the design of clean air ducts (low pressure side for
turbocharger) will react to changes in vacuum caused by slow/steady
engine vacuum increase, and sudden/short term vehicle acceleration
with a dirty air filter. The test determines a change in the cross
section profile of the duct at the Excursion Temperature based on
Location (ETL), degrees Celsius. See Subsystem Technical
Specification (SSTS) Normal Operating Temperature Section.
Applicability. This test is for the clean air
duct assembly of the air induction system. This test is also
applicable to the dirty side air duct if required.
