2. Diesel exhaust fluid - Wikipedia

   en.wikipedia.org/wiki/Diesel_exhaust_fluid

   Diesel exhaust fluid (DEF; also known as AUS 32 and sometimes marketed as AdBlue [3]) is a liquid used to reduce the amount of air pollution created by a diesel engine. Specifically, DEF is an aqueous urea solution made with 32.5% urea and 67.5% deionized water. DEF is consumed in a selective catalytic reduction (SCR) that lowers the ...

3. Diesel exhaust - Wikipedia

   en.wikipedia.org/wiki/Diesel_exhaust

   A diesel engine that operates below the smoke limit produces a visible exhaust. In modern motor vehicle diesel engines, this condition is generally avoided by burning the fuel in excess air even at full load. The primary products of petroleum fuel combustion in air are carbon dioxide, water, and nitrogen.

4. Selective catalytic reduction - Wikipedia

   en.wikipedia.org/wiki/Selective_catalytic_reduction

   Diesel engines manufactured after January 1, 2010 are required to meet lowered NOx standards for the US market. All of the heavy-duty engine (Class 7-8 trucks) manufacturers except for Navistar International and Caterpillar continuing to manufacture engines after this date have chosen to use SCR.

5. Diesel fuel - Wikipedia

   en.wikipedia.org/wiki/Diesel_fuel

   Diesel fuel, also called diesel oil, heavy oil (historically) or simply diesel, is any liquid fuel specifically designed for use in a diesel engine, a type of internal combustion engine in which fuel ignition takes place without a spark as a result of compression of the inlet air and then injection of fuel. Therefore, diesel fuel needs good ...

6. Diesel particulate filter - Wikipedia

   en.wikipedia.org/wiki/Diesel_particulate_filter

   Some newer diesel engines, namely those installed in combination vehicles, can also perform what is called a Parked Regeneration, where the engine increases RPM to around 1400 while parked, to increase the temperature of the exhaust. Diesel engines produce a variety of particles during the combustion of the fuel/air mix due to incomplete ...

7. Diesel engine - Wikipedia

   en.wikipedia.org/wiki/Diesel_engine

   1952 Shell Oil film showing the development of the diesel engine from 1877. The diesel engine, named after the German engineer Rudolf Diesel, is an internal combustion engine in which ignition of diesel fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is called a compression-ignition engine (CI engine).

8. Catalytic converter - Wikipedia

   en.wikipedia.org/wiki/Catalytic_converter

   The urea solution is also referred to as diesel exhaust fluid (DEF). Diesel exhaust contains relatively high levels of particulate matter. Catalytic converters remove only 20–40% of PM so particulates are cleaned up by a soot trap or diesel particulate filter (DPF). In the U.S., all on-road light, medium, and heavy-duty diesel-powered ...
