1. Investigation and Optimization of the Acoustic Performance of Exhaust Systems
Sammanfattning : There is a strong competition among automotive manufacturers to reduce the radiated noise levels. One important source is the engine exhaust where the main noise control strategy is by using efficient mufflers. LÄS MER
2. On the Agglomeration of Particles in Exhaust Gases
Sammanfattning : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. LÄS MER
3. Corrosion of Stainless Steel in Diesel Exhaust Gas After-treatment Systems with Urea Injection
Sammanfattning : The demands on lowering the emissions from fossil fuel keep increasing. Together with higher demands of longer component lifetime and lighter vehicles for lower fuel consumption this has led to an increasing use of stainless steels in exhaust after-treatment systems. LÄS MER
4. Particle Characterization in the Exhaust Devices of Direct Injection Engines
Sammanfattning : Minimizing pollutants are of utmost importance to ensure sustainability in transportation. Particle emissions from internal combustion engines are especially harmful to human health, while also contributing to global warming. LÄS MER
5. Numerical modelling of particulate matter deposition in exhaust gas after-treatment systems
Sammanfattning : As urban air quality declines, the corresponding levels of particulate matter (PM), that include pollutants such as sulfates, nitrates and black carbon, rise posing the greatest risks to human health. Hence, the control of these particulate emissions constitutes a major global challenge that commands serious attention. LÄS MER
