One of the trucks was equipped with exhaust gas recirculation (EGR); three were equipped with EGR and a selective catalytic reduction (SCR) device. EGRs were primarily introduced for on-road heavy-duty diesel engines over a decade ago to meet the tighter MY 2004 NO x standard (2 g/bhp-hr). deionized water); poor DEF quality; and.
