DPF and DOC

Diesel Oxidation Catalysts (DOC) are catalytic converters designed specifically for diesel exhaust and equipment to reduce Carbon Monoxide (CO), Hydrocarbons (HC) and Particulate Matter (PM) emissions. DOC's are simple, inexpensive, maintenance-free and suitable for all types and applications of diesel engines. The diesel particulate filter (DPF) is an exhaust aftertreatment device that traps particulate matter such as soot and ash from diesel engines. It is designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Both of them are an important part the vehicle’s emissions system.

HONGHU Exhaust has developed a variety of DPF which maintain the configuration required to manufacture an equivalent OEM replacement. The range of direct fit DPF’s has been designed and tested using the latest flow and emissions technology to ensure all units meet the emission standard and OEM equivalent specification.
