BMW sedans equipped with Engelhard technology that enables the cars to actually destroy smog as they are driven will be available in showrooms in five US states by the end of this summer.
Engelhard’s PremAir ozone-destruction catalyst will be featured on BMW Partial Zero Emission Vehicles (PZEVs) sold in California, New York, Vermont, Maine and Massachusetts. The first of these PZEVs to be equipped with PremAir are model – year 2003 BMW 325i sedans with automatic transmission.
PZEV certification is granted by the California Air Resources Board (CARB) to extremely clean vehicles under the state’s Zero Emission Vehicle Program. The Northeast states have adopted the California program, which was established in 1990 with the goal of eventually reducing vehicle emissions to zero. PZEV cars use advanced technology to minimise their environmental impact.
PremAir is one of the technologies approved by the CARB for PZEV credits. PremAir also is eligible for credits under the US Environmental Protection Agency’s national Low Emission Vehicle Program.
‘Traditional pollution-control technologies stop contaminants at the source, before they reach the environment. PremAir was the first technology designed to destroy ozone already in the ambient air regardless of the source,’ said Dr. Thomas Holcombe, director, PremAir.
PremAir is a catalytic coating applied to a vehicle’s radiator that destroys up to 80% of the harmful ground-level ozone in the air that passes across it. Ground-level ozone is the major component of smog. It has been directly linked to asthma and other respiratory problems as well as to damage to vegetation.
Vehicles equipped with PremAir were first available in 2000. The technology is currently featured on several models sold worldwide. Other applications for PremAir include truck and bus radiators and commercial and residential air-conditioner condensers.
