This course is designed to introduce the diesel exhaust aftertreatment system converters: diesel oxidation catalyst (DOC), diesel particulate filter (DPF), Selective Catalytic Reduction (SCR), and Ammonia Slip Catalyst (ASC). This course also describes the key parameters for controlling their operation during engine calibration to meet emissions.

Engineers focused on reducing diesel engine emissions should attend this course.
