Abstract
Official abstract text for this publication.
A cold start emissions reduction diagnostic system for an internal combustion engine includes a coolant temperature module including a coolant temperature input, and a memory module having a coolant temperature look-up table. The cold start controller also includes a cold start emissions reduction module configured to selectively compare coolant temperature values with desired emission values in the look-up table to determine at least one of a fuel injection timing and a fuel injection quantity to establish a desired cold start emissions profile. A fuel injection monitoring module is configured and disposed to sense changes in fuel injection timing and fuel injection quantity, and an emission reduction diagnostic model module is configured and disposed to determine emission parameters based on the changes in the one of the fuel injection timing and fuel injection quantity sensed by the fuel injection monitoring module during a cold start.
