  1. What the heck is SCR?
    The US EPA mandated that by Jan 2010 the NOx levels emitted from diesel engines must be reduced to near zero levels. Due to our close economic ties, Canadian policies closely mirror the Americans.
    Since the late 90's engine manufacturers have been required to meet a series of emission benchmarks. These benchmarks are commonly known as Tier I, II, III, Intern Tier IV and Tier IV Final.

    Each "tier" has required new technology's to be invented and implemented. Various methods of NOx and particulate reduction have included recycling of exhaust (EGR), particulate filters (DPF), engine timing and temperature, and of course SCR.

    Simply put, SCR is the method by which DEF is mixed with exhaust to convert NOx into the common atmospheric gases; nitrogen and water vapour.



  2. What is Diesel Exhaust Fluid or DEF made of?
    All diesel exhaust fluid, no matter what brand, consists of water and urea.
