Burner technology

摘要

Can a burner system offer an alternative gateway to improved catalyst performance and reduced tailpipe emissions with a lower CO_2 penalty? Impending changes to pollutant regulations in the EU and USA, such as the yet-to-be-defined Euro 7, will mandate significant further cuts to vehicle emissions, not only within a test cycle but also under real driving conditions. This means OEMs will need to considerably reduce emissions following engine start, in particular cold starts, and during extended low load cycles. This will necessitate the introduction of technologies that improve either engine-out emission performance or aftertreatment efficiency. Of the two approaches, developments in aftertreatment technology are typically easier to apply to existing vehicles and powertrains, or those scheduled for introduction in the near term.
