Diesel Oxidation Catalyst (DOC)
The primary function of a DOC in a Diesel After Treatment System (ATS) is to ensure sufficient oxidation of CO and THC, and to oxidize, 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 to the DPF at normal operation conditions, without the necessity of any external measures and is a highly favored 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 is applied on metallic as well as ceramic base substrates.

Dinex meets all levels of regulation
The Advanced US EPA07/10 regulations need complex after-treatment systems (ATS) to fulfill all regulatory requirements. After initial implementation in year 2007, US EPA regulations have been updated step by step over the years with primary focus on real driving emissions (RDE) and in-service conformity.
Dinex supports Heavy Duty and Medium Duty commercial vehicles with advanced catalyst coating technologies (DOC, DPF, SCR). Which are among the best in class. The wide range of technologies provide the flexibility to modulate the ATS layout to the full benefit of our customers as per their duty cycle and application requirements. The catalyst technologies have been rigorously tested by major OEMs world-wide and meet the most stringent engineering targets and real driving emissions performance requirements.
With close to 30 years of experience in canning & housing as well as patented technologies for compact mixers, Dinex builds robust and flexible ATS canning to meet a variety of packaging and space requirements.
