How does an ARD Head work?
The Fuel Nozzle in the ARD Head is used to supply diesel fuel to the Aftertreatment System. This fuel ignites and creates a high enough temperature to burn the soot from the DPF core.
What is the ARD Head?
This diesel exhaust ARD HEAD is used for 2007-2009 CATERPILLAR AfterTreatment Systems in on-road truck applications, and some off-road applications. This was one of the first Caterpillar Aftertreatment strategies used to burn particulate matter (or soot) in the diesel particulate filter.
What does a DPF do on a diesel?
A DPF typically uses a substrate made of a ceramic material that is formed into a honeycomb structure. In order to reduce emissions from diesel vehicles, diesel particulate filters capture and store exhaust soot, which must be periodically burned off to regenerate the filter.
What’s the difference between the DPF and the Doc?
Both the DOC and the DPF are honeycomb ceramic filters. However, unlike the DOC, the DPF is a wall-flow filter that traps any remaining soot that the DOC couldn’t oxidize. The soot remains in the DPF until it is regenerated either passively or actively.
How does the fuel nozzle in an ard head work?
The Fuel Nozzle in the ARD Head is used to supply diesel fuel to the Aftertreatment System. This fuel ignites and creates a high enough temperature to burn the soot from the DPF core. ESU completes 100% testing and inspection of all remanufactured parts, to ensure the ARD Head you buy, functions flawlessly with 100% confidence!
What happens when Ash builds in DPF filter?
As ash builds inside the DPF the number of active regenerations increase causing poor fuel economy, extreme high temperatures, and more constant back pressure that can be detrimental to the turbo charger. The longer the ash is left inside the DPF the greater the chance of it hardening into a plug which closes off a portion of the filter.
Can a caterpillar ard head fail over time?
This was one of the first Caterpillar Aftertreatment strategies used to burn particulate matter (or soot) in the diesel particulate filter. This ARD Head can fail over time, stopping the regeneration function of the CAT aftertreatment system, and plugging the DPF core.
