1. Particulate Emissions Associated with Diesel Engine Oil Consumption
Sammanfattning : Particulate emissions from diesel engines have been a key issue for diesel engine developers in recent decades. Their work has succeeded in reducing the exhaust particles from the combustion of fuel, which has led to increasing interest in the contribution of particulates from lubrication oil. LÄS MER
2. Multiscale methods for the fundamental understanding of diesel soot mitigation
Sammanfattning : Current regulations for diesel exhaust emissions cannot be met by engine improvements alone, and for this reason the diesel particulate filter (DPF) is a widely used aftertreatment component for the control of diesel particulate matter (PM). The DPF functions by trapping PM and destroying it by oxidation. LÄS MER
3. Particulate Flows in Aftertreatment Systems
Sammanfattning : Emissions from internal combustion engines contain many components that have a detrimental effect on the environment and on human health, such as nitrogen oxides (NOx) and particulate matter (PM). In addition, the final product of any combustion of fossil fuel - carbon dioxide (CO2) - contributes to global warming. LÄS MER
4. Diesel exhaust and wood smoke : mechanisms, inflammation and intervention
Sammanfattning : Background Particulate matter (PM) air pollution is associated with increased respiratory and cardiovascular morbidity and mortality. Diesel engine exhaust (DE) and wood combustion are major contributors to ambient air pollution and adverse health effects. LÄS MER
5. Eulerian-Lagrangian modeling of particle motion in exhaust gas aftertreatment systems
Sammanfattning : In the work to design and optimize new aftertreatment system devices for NOx reduction and particulate matter removal in lean engine exhaust (such as diesel exhaust), it is of great help to be able to perform quick, robust and reliable computer simulations of system performance. A suitable platform for such simulations is Computational Fluid Dynamics (CFD) software. LÄS MER
