Dinex - Model DOC -Diesel Oxidation Catalyst
The primary function of DOC in a Diesel ATS is to ensure sufficient oxidation of CO and THC, and to oxidise, NO in the exhaust to NO2.
Dinex DOC technologies are based on a high thermal stability wash coat formulation with excellent CO and THC light-off characteristics and high NO2 formation. The typical CO and THC conversion levels seen are above 95%.
A high level of NO2 generated on DOC ensures passive soot oxidation on DPF at normal operation conditions, without the necessity of any external measures and is a highly favoured method.
Excellent THC light-off characteristics support and offer flexibility in designing active DPF regeneration strategies through external measures like HC dosing.
The PGM loading and the Pt:Pd ratio can be modulated based on DPF regeneration strategies and requirements.
The catalyst coating can be done on metallic as well as ceramic base substrates.
