2. Diesel exhaust - Wikipedia

   en.wikipedia.org/wiki/Diesel_exhaust

   Exposure to diesel exhaust and diesel particulate matter (DPM) is an occupational hazard to truckers, railroad workers, occupants of residential homes in the vicinity of a rail yard, and miners using diesel-powered equipment in underground mines. Adverse health effects have also been observed in the general population at ambient atmospheric ...

3. Diesel exhaust fluid - Wikipedia

7. Diesel particulate filter - Wikipedia

   en.wikipedia.org/wiki/Diesel_particulate_filter

   Cordierite Diesel Particulate Filter on GM 7.8 Isuzu. Unlike a catalytic converter which is a flow-through device, a DPF retains bigger exhaust gas particles by forcing the gas to flow through the filter material before exiting; [2] [29] however, the DPF does not retain small particles.
