The HD Code II from CanDo is the first handheld tool to include DPF regenerations, and it improves upon the design of the original HD CODE PCAT. In fact, after only 33,000 miles, the amount of ash in the DPF may equal the amount of soot (prior to regeneration), and after 150,000 miles, nearly 80% of the material trapped in the DPF is ash.

Desulfation Frequency LNT Durability Improvement by Less Frequent Desulfation: In this system the exhaust enters a diesel oxidation catalyst (DOC) first. The Cat Regeneration System is designed to work transparently, without any interaction needed from the operator. Background: Frequency and classification of anemia in terms of regeneration status and erythrocyte indices are not well described in cats. System goes 200 - regen start. Effective Aftertreatment Diesel Particulate Filter Cat Regeneration System This truck came in with a p244b - dpf high differential pressure, p2463 - dpf high soot accumulation, p2459 - dpf regen frequency. Although the ash only makes up a very small fraction of the incoming soot, it remains in the DPF indefinitely and builds up to high levels. Purpose and Function. Abstract: Emission aftertreatment—diesel particulate filters and SCR catalysts—was widely introduced on heavy-duty diesel engines to meet US 2007 emission standards.However, there were differences in the technology paths—some manufacturers initially attempted to meet the 0.2 g/bhp-hr NOx limit using high EGR rates, without NOx aftertreatment. Sits there awhile. High-horsepower engine manufacturers have depended on electronic controls, air-flow improvements, internal combustion optimization, advanced fuel delivery systems and other engine-design solutions to comply with Tier 2 standards, but the consensus among diesel suppliers is that exhaust aftertreatment technologies will be necessary to lift emissions control to Tier 4 Final levels. The Cat C9.3B combines a new high pressure common rail fuel system and advanced aftertreatment technology to produce 340 kW of power. Find out the real problem behind your diesel truck's aftertreatment problems — blocked DPF filter, frequent manual regens — and how to solve it. Regeneration occurs when the filter element reaches . The tool boasts a simple, easy to use interface. Diesel exhaust particulate filters (DPFs) are used in all light-duty diesel vehicles, since 2007, to meet the exhaust emissions standards.The heated exhaust gas from the DOC flows into the DPF, which captures diesel exhaust gas particulates (soot) to prevent them from being released into the atmosphere. Diesel Exhaust Particulate Filter. temperatures are high enough to initiate combustion of Hours Between Regeneration: If you believe that you have a frequent regeneration issue, please consult the Aftartreatment Diesel Paritculate Filter - Excessive Automatic and/or Stationary Regeneration Sympton Tree - t147. (866) 811-0110 (866) 811-0110 “Passive” regeneration occurs when the exhaust gas . Input Rationality High Input Other Rationality Regeneration Frequency Emission Threshold Regeneration Frequency Functional Monitor in Lieu of Emission Threshold Incomplete Regeneration Functional Monitor the temperature required for the combustion of the accumulated PM, converting it primarily to ash, gaseous carbon dioxide (CO2) and water (H2O).

When the DPF filter load reaches a predetermined level, the ECU activates a regeneration process to increase the DPF temperature to over 550˚C. Stay with us… A cat’s purr frequency is exactly 26 Hertz. Under most operating conditions, engine exhaust is hot enough to oxidize soot through passive regeneration. When regeneration is complete, the engine returns to idle. The SCR uses Diesel Exhaust Fluid to reduce the levels of NOx in the engine exhaust. With exceptional power density, the C9.3B allows for platform downsizing while maintaining reliability and durability. 5246-15 Aftertreatment SCR Operator Inducement Severity : High - least severe (1) Downstream of the cylinders, Komatsu uses an aftertreatment setup it calls a Komatsu Diesel Particulate Filter. Hydrocarbon Doser from Turbo 2. Vehicle Engine Aftertreatment System Simulation (VEASS) Model: Application to a Controls Design Strategy for Active Regeneration of a Catalyzed Particulate Filter 2005-01-0970 Heavy-duty diesel engine particulate matter (PM) emissions must be reduced from 0.1 to 0.01 grams per brake horsepower-hour by 2007 due to EPA regulations [ 1 ]. Dealer Repair Frequency statistics show Caterpillar ... Particulate Filter featuring its own Cat Regeneration System (CRS).
