Cold-start hydrocarbon emissions control
This article describes an effective, energy-efficient strategy for dealing with this problem using HC traps and heat-exchange related catalyst beds that have been successfully tested. The worldwide regulatory climate for continued and dramatic reductions in vehicle exhaust emissions will continue unabated for some time. The best known of these mandates includes California Air Resources Board`s Low Emission Vehicle (CARB LEV) program, the Ozone Transport Commission`s recent petition to the EPA for partial adoption of CARB`s LEV program, and the European Economic Community`s proposed staged multi-tier approach to reduce auto exhaust pollution. Since up to 70% of hydrocarbon tailpipe emissions occur during the cold-start portion of the Federal Test Procedure (FTP), significant reductions in total FTP HC emissions must include a cold-start HC abatement strategy.
