Abstract
BOSMAL recently hosted the First International Exhaust Emissions Symposium, which featured thirteen presentations on the topics of emissions regulation and the influences this legislation exerts on test procedures, emissions reduction efforts and drivetrain technologies. Emissions test methods and facilities will have to alter to reflect the reduced emissions limits to be introduced in the near future. Emissions reduction efforts include further development of catalyst systems and the development of fuels. Biofuels and biofuel blends are key in this area. Advanced lubricants will also play a key role. The potential for synergy between these actors is evident. In addition to aftertreatment systems, drivetrain technologies such as hybrid drive and exhaust gas reformation clearly have the potential for substantial emissions reduction for a wide range of pollutant species. Automotive research is at the heart of each of these areas of development, and will be ongoing in the industry’s continued efforts regarding harmful exhaust emissions.
Highlights
The main drivers that have an influence on current and future personal transportation development are: – climate change as the biggest environmental challenge: strong action dedicated to the contribution of the transport sector to the reduction of greenhouse gas emissions, global CO2 legislation targets for new passenger cars (PC) and light commercial vehicles (LCV); – emissions regulation development at European, US and Asian levels, regulation as an incentive for innovation
The metal balance and dimensioning of the DPF are crucial in controlling outputs from DPF cleaning in urban environments. These findings reveal that NO2 production for use as an input for SCR systems is clearly linked to HC and CO light-off, and that lower space velocities, higher Pt content and homogenously coated filters perform best
It appears that usage of alternative Diesel fuels could be a strategy of great importance in the drive to rectify the problem of PM emission associated with CI engines
Summary
Global trends in emissions regulation and reduction (perspectives from the 1st International Exhaust Emissions Symposium). BOSMAL recently hosted the First International Exhaust Emissions Symposium, which featured thirteen presentations on the topics of emissions regulation and the influences this legislation exerts on test procedures, emissions reduction efforts and drivetrain technologies. In addition to aftertreatment systems, drivetrain technologies such as hybrid drive and exhaust gas reformation clearly have the potential for substantial emissions reduction for a wide range of pollutant species. Światowe trendy w zakresie rozwoju norm oraz redukcji emisji związków szkodliwych spalin (na podstawie materiałów zaprezentowanych na Pierwszym Międzynarodowym Sympozjum Emisji Spalin). Zaawansowane technologie układów napędowych takich jak układy hybrydowe oraz ograniczanie emisji spalin z silnika mają poważny wpływ na redukcję emisji w szerokim zakresie występujących rodzajów związków szkodliwych spalin.
