Aftertreatment Regeneration Device (ARD)
Diesel Oxidation Catalyst (DOC)
Diesel Particulate Filter (DPF)The Diesel Oxidation Catalyst (DOC) oxidizes the carbon monoxide and the hydrocarbons that are not burnt in the exhaust gas into carbon dioxide and water. This is a through flow device that will continue to operate during all normal engine operating conditions.The Diesel Particulate Filter (DPF) collects all solid particulate matter in the exhaust gas.The Aftertreatment Regeneration Device (ARD) increases the exhaust gas temperature to a sufficient level. The soot that is collected in the DPF is oxidized to carbon dioxide.A flexible exhaust pipe connects the engine to the Clean Emissions Module (CEM). Refer to Disassembly and Assembly for the correct procedure to install the flexible exhaust pipe.The solid particulate matter that is collected by the DPF consists of soot (carbon) from incomplete combustion of the fuel and inorganic ash from the combustion of any oil in the cylinder.The rate of accumulation of ash is slow. The filter is designed to contain all the ash that is produced until the defined service interval.The soot that is collected must be removed at regular intervals. Removal of the soot is achieved by elevating the exhaust gas temperature by burning fuel in the ARD for a short time period. If the exhaust gas temperature is high enough, the ARD oxidizes the soot into carbon dioxide, which then passes through the filter and into the atmosphere. The ARD may automatically switch ON and OFF. The ARD may be manually controlled by the operator. The ARD is controlled by the sensor for the soot level. The sensor for the level of soot will ensure that the level of soot in the filter is kept within limits. This is referred to as a regeneration of the filter.In order to regenerate the DPF at the right time, the engine ECM must know how much soot is in the DPF. Measurement of soot is accomplished through the following means:
Delta pressure measurement across the DPF
Radio frequency measurement across the DPF
Calculated model based on developed engine out soot measurementsThe information gathered from these three inputs is then converted into a percentage of soot output that is viewable through electronic soot level gauges. These gauges can be found in the cab of most applications as well as various operator displays that are used with most engines. The soot level may be displayed as a graphical bar, or as an actual percentage. Soot level can also be viewed through the electronic service tool.The frequency of regeneration will depend on the operating conditions of the engine. The frequency of regeneration will depend on the ambient conditions of the operation of the engine. Regeneration will be most frequent if the application operates with a high transient content or the atmospheric temperature or the altitude is high.Soot Level Outputs
The soot level percentage that is generated by the engine ECM is used in determining:
When to activate the DPF lamp
When to activate the action lamp (for high soot load events)
When to activate the action alarm (for high soot load events) (if equipped)
When to activate the forced engine low idle strategy
When to activate the forced engine shutdown strategy
Operator initiated regeneration lockout
When a force switch regeneration is allowed
When a low speed regeneration is allowed
When a high speed regeneration is allowedDPF Lamp - The DPF lamp will be illuminated at a 90 percent soot level on engines.Action Lamp - The action lamp will be illuminated at a 100 percent soot level for engines. The DPF lamp will remain on with the action lamp.Action Alarm - The action alarm will be activated at a 116 percent soot level for engines.Forced low idle strategy - The forced low idle strategy will be activated after the soot level has been at 116 percent for 5 minutes. At this time, the engine will automatically drop to the programmed low idle speed. The only method to unlock
