Ulev, Sulev & Diesel

Turns out the Californian SULEV standard is very strict. I found the following presentation concerning Advanced Diesel Engines for the EU and US auto markets by Prof Dr.-Ing. Peter Hofbauer.

If this interests you, check page 12 (for current standards), 24 (for an idea what can be done) and the last one (for sheer fun).

Essentially, Diesel in North America cannot achieve even ULEV standards unless Sulphur content goes below 10 ppm, as the NOx Traps would burn out at anything higher.

  • A review by the “4 Clean Air” group.
  • Another article on Improved Catalyst Systems states that “The emission levels already achieved in prototype vehicles in the USA make it clear the in the future be possible to build vehicles whose exhaust gases in urban areas will be cleaner then the air taken in…”
  • How about a step-by-step review of the workings of a catalyst.
  • Urea a molecule I just learned about.
