Dinex DOC solution for passive and active regeneration The latest generation DOC from Dinex is based on a high thermally stable wash coat formulation with low CO and THC light off and high NO 2 formation. The design of the wash coat and the Pt:Pd ratio at the inlet and outlet zones of the DOC is done based on the application requirements, i.e. it can be designed for passive regeneration only as well as for high frequency of active regenerations. This wash coat concept is available on metallic and ceramic substrates.
