Vehicle mass targets

The steel industry is also looking into new ways to utilize high-strength steel in the construction of motor vehicles in order to reduce vehicle mass. Other developments are steel-plastic sandwich structures and innovative manufacturing processes. The American Iron and Steel Institute plans an advanced concept vehicle project targeted to meet the 2004 PNGV vehicle and crash requirement.

The application of a selective pyrolysis process to the recovery of chemicals from waste PU foam is described. The reaction conditions are controlled so that target products can be collected directly from the waste stream in high yields. Molecular beam mass spectrometry is used in small-scale experiments to analyse the reaction products in real time, enabling the effects of process parameters such as temperature, catalysts and co-reagents to be quickly screened. Fixed bed and fluidised bed reactors are used to provide products for conventional chemical analysis to determine material balances and to test the concept under larger scale conditions. Results are presented for the recycling of PU foams from vehicle seats and refrigerators. 12 refs. 

Diesel particle filters are a very efficient means of reducing PM mass emissions from diesel vehicles, but do not directly target NOx. However, most diesel particulate filter (DPF) systems contain catalytic materials which assist in the DPF regeneration (the combustion of PM accumulated on the filter to clean the DPF and prevent blockage). Such catalytic materials can have a similar impact to DOCs...
