摘要

Economic and environmental amenities of diesel engines such as high fuel efficiency led to a steady increase in popularity. However, their major disadvantage with regard to environmental and health protection is the typically enhanced production of diesel particulate matter (DPM) comprising soot and unburned carbonaceous compounds. Stricter emission levels, for example, the Euro Ⅰ to Ⅵ standards in the European Union, and tax incentives are imposed. One strategy to lower this burden is the optimization of fuel combustion in the engine as typically realized by a turbocharger. Here, the drastically lowered fuel droplet size negatively influences the DPM nanostructure. Smaller particles may penetrate more deeply into the respiratory tract, where their large surface-to-volume ratio could allow for more biological interaction. It could turn out to be ironical history that huge effort made in this direction is driven by the increasing awareness of the public on the toxicity of diesel soot.
