Darwin Diesel Oxidation Catalyst (DOC)
At REGEN NT, we provide professional Diesel Oxidation Catalyst (DOC) cleaning and maintenance for diesel vehicles and machinery across Darwin and surrounding areas. DOCs play a crucial role in your emission control system, converting harmful pollutants like carbon monoxide and hydrocarbons into less harmful gases before they exit the exhaust.
Over time, DOC units can become clogged with soot and debris, reducing their efficiency and affecting overall engine performance. Our specialised service restores flow, boosts fuel economy and supports compliance with environmental standards. DOC maintenance also improves the performance of connected components like the Diesel Particulate Filter (DPF), ensuring a cleaner and more efficient system overall.
Using advanced cleaning technology and tailored methods, we service a wide range of diesel vehicles—from light commercial units to heavy-duty equipment. For expert DOC maintenance that keeps your engine running at its best, contact REGEN NT today on 0405 360 085.

How it Works
A Diesel Oxidation Catalyst (DOC) is a key part of a diesel engine’s emission control system. It works by oxidising harmful exhaust pollutants—such as carbon monoxide (CO), hydrocarbons (HC) and some particulate matter—into less harmful substances like carbon dioxide and water vapour.
Inside the DOC is a honeycomb structure coated with precious metals like platinum and palladium, which trigger a chemical reaction as hot exhaust gases pass through. This process not only reduces toxic emissions but also helps increase the temperature of the exhaust stream, improving the performance of downstream components like the Diesel Particulate Filter (DPF).
Regular maintenance keeps your DOC functioning efficiently and supports cleaner engine operation.
