ABSTRACT:
An internal combustion engine has a system, including diagnostics, for providing oxygen enriched air so as to control emissions of unburned hydrocarbons and carbon monoxide. The system includes the capability of determining whether the oxygen enrichment system is providing suitable mass flow to the engine and whether oxygen enrichment is available according to the specifications of the enrichment device.
