4. Diesel exhaust - Wikipedia

   en.wikipedia.org/wiki/Diesel_exhaust

   Diesel exhaust is the exhaust gas produced by a diesel engine, plus any contained particulates. Its composition may vary with the fuel type, rate of consumption or speed of engine operation (e.g., idling or at speed or under load), and whether the engine is in an on-road vehicle, farm vehicle, locomotive, marine vessel, or stationary generator ...

5. Selective catalytic reduction - Wikipedia

   en.wikipedia.org/wiki/Selective_catalytic_reduction

   Most catalysts have finite service life mainly due to the formation of ammonium sulfate and ammonium bisulfate from sulfur compounds when high-sulfur fuels are used, as well as the undesirable catalyst-induced oxidation of SO 2 to SO 3 and H 2 SO 4. In applications that use exhaust gas boilers, ammonium sulfate and ammonium bisulfate can ...

   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.
