This document reports on a comparison of start emissions for the
two test cycles using data from a sample of five vehicles tested
at the EPA National Vehicle and Fuel Emissions Laboratory in Ann
Arbor, Michigan. The purpose of the analysis is to determine if,
during the start portion of the cycles, there is a significant
difference between the cycles in their emissions attributable to
a cold start condition.
