SCR: selective catalytic reduction - one of the most popular methods to reduce NOx from Diesel engine exhaust, where urea is injected into the exhaust stream to react to the exhaust gasses and then react to a catalyst element to convert the NOx to nitrogen and water.

BOI: Beginning of Injection

EOI: End of Injection

PM: particulate matter, mostly unburned hydrocarbons, commonly referred to as soot.

USEPA: United States Environmental Protection Agency 😉

Iíve got more, sadly.
