About this product:
For almost a decade, there had not been an affordable test protocol for
certifying emissions-related, on-road diesel parts or systems in
California. During a portion of that time, SEMA engaged in the
development of a test method (as an alternative to the very costly
engine dynamometer protocol required of the diesel OEMs) that would
allow California Air Resources Board (CARB) Executive Orders (EOs) to be completed without imposing significant financial burdens on applicants.
However, the situation became more critical when
light- and medium-duty diesels were added to the California Bureau of
Automotive Repair’s (BAR) smog-check program beginning January 1, 2010.
