Micro-training logo

This micro-credential course is part of a training initiative by Canadian Colleges for a Resilient Recovery (C2R2) and the Government of Canada to provide workers with new skills needed to support a clean economy.

The Diesel Exhaust Emission Reduction Systems micro-credential course teaches students the latest technologies employed in light- and heavy-duty emission reduction systems and is imperative for the diagnosis and repair of after-treatment systems and reducing harmful exhaust emissions.

This course provides:

  • Proficiency in emission reduction theory and the tiers of emission control.
  • Understanding of operation, control strategies and diagnostic procedures for diesel after-treatment systems.
  • Knowledge of the fundamentals to diagnose and repair Exhaust Gas Recirculation (EGR) systems, Diesel Particulate Filter (DPF) systems, as well as Selective Catalyst Reduction (SCR) systems.

This course is developed for diesel and heavy-equipment technicians, as well as for related trades (see prerequisites below).
