What is diesel oxidation catalyst and its features

DOC stands for diesel oxidation catalyst. It is an after-treatment element that helps transform hydrocarbons and carbon monoxide into water and carbon dioxide. A field inspected DOC complies with the strict emission standards. It’s important to choose an experienced and trustworthy manufacturer of emission control products. A leading manufacturer in the industry can provide competitively priced and highly efficient diesel oxidation catalyst. These DOCs will assist equipment operators abide by CARB, OSHA, CAL OSHA, RICE NESHAP, MOL, and EPA regulations through effective reduction of harmful concentrations of hydrocarbon (HC), particulate matter (PM), and carbon monoxide (CO) exhaust waste by approximately 90%.

Features of diesel oxidation catalyst

To have a detailed understanding of what is diesel oxidation catalyst, let’s discuss its key features.

  1. Highly efficient tortuous flowpath catalytic core

DOC entails an exclusive tortuous flowpath catalytic core that incorporates a mixed curved flow cell layout. It is helpful in taking benefit of physical characteristics of dangerous pollutants, boosting contact with catalytic core surface. On the other side, a straight flowpath DOC design allows a certain proportion of dissolvable organic particulate to stream via catalytic core with no contact with the catalyst.

  1. Minimum exhaust gas backpressure

An efficient diesel oxidation catalyst core comprises of extremely thin, high-strength metallic walls that decrease exhaust backpressure limit to a minimum. The working efficiency of the engine will be not influenced under high speed/load engine operating circumstances.

  1. Top-quality catalytic coating

A diesel oxidation catalyst is designed in such a manner that it features high-quality precious metal coating over a homogenous high porosity wash coat. This coating gives long life and enhances the thermal longevity of catalyst, boosting performance in unfavorable operating conditions.

  1. Easy installation and low maintenance

DOC core design helps reduce the production of compiled particulate matter. Its diesel exhaust gas purifier has an efficient and compact design that permits easy installation. Furthermore, the equipment downtime will be minimum that allows low maintenance.

  1. Higher physical strength

The excellent features of diesel oxidation catalyst provide great reliability and stability under severe vibration and very high temperatures. Folded catalytic tips and thick foil retainer rings improve the entire structural strength.

Options for diesel oxidation catalyst

  1. Clamp-on style DOC (F-model or P-model)

The P-model clamp-on style DOC is an entirely welded purifier unit that gets installed alongside the engine exhaust system after/before the standard equipment muffler. Whereas F-Model Clamp-on style DOC is identical to a plain-style exhaust purifier and can be connected to any type of engine. The clamp-on style models incorporate fast release V-band clamps along with gaskets to permit easy discharge of catalytic core. It’s recommended to install F-Model or P-Model DOC nearby the engine turbocharger outlet or manifold outlet to let the catalyst work better.

  1. DOC muffler

The full replacement DOC Muffler involves the direct replacement of the originally manufactured equipment muffler. Simply take off the original equipment muffler and directly install the DOC muffler in place. The DOC muffler manufacturer will need equipment model, make, stock muffler part number, and equipment serial number at the time of placing an order.
