1、How does the Cummins Particulate Filter remove particulate matter (PM)? Cummins Particulate Filter in most cases replaces the Tier 3 muffler and provides equivalent or better sound reduction. The Cummins Particulate Filter consists of four sections: an inlet, a Diesel Oxidation Catalyst (DOC), a Diesel Particulate Filter (DPF) and an outlet.

3、What is active regeneration? Active self-regeneration occurs when there is not sufficient heat in the exhaust to convert the PM being collected in the DPF. Exhaust temperatures are raised by injecting a small amount of fuel upstream of the Cummins Particulate Filter. The resulting chemical reaction over the DOC raises exhaust gas temperatures high enough to oxidize the PM from the filter. This is all done without any operator intervention. Cummins Tier 4 Interim system is designed to minimize the need for active self-regeneration. The overall fuel consumption increase due to active regeneration of the particulate filter is barely measurable – approximately 0.1% for most applications. This minor increase resulting from active regeneration is included within Cummins overall Tier 4 fuel efficiency improvement of up to 5%. Cummins field tests have proven the majority of active regenerations will be less than 1% of the total operating time. 4、What is a stationary regeneration? Stationary, or parked, regeneration is the same as active regeneration but takes place while the equipment is not being operated. It offers the equipment operator the option, if needed, of performing regeneration outside the normal duty cycle. Using this option may only be required in a very limited number of applications. Does the Cummins Particulate Filter get hotter than a typical muffler during active regeneration? Active self-regeneration takes place typically less than 1% of equipment operating time. The skin temperature of the Cummins Particulate Filter, which is double-thermally insulated, is actually lower than the muffler skin temperature of today’s Tier 3 powered machines.

Exhaust flows out of the engine and into the Cummins Particulate Filter. It passes through the DOC and then into the DPF where PM is collected on the walls of the DPF. The PM collected is then oxidized to remove it from the DPF. This is known as regeneration. When operating conditions maintain sufficient exhaust temperatures, the DPF is continually self-regenerating. This is known as passive regeneration and results in clean exhaust out of the tailpipe. On very infrequent occasions, an active self-regeneration is required to remove a build-up of PM in the DPF, due to insufficient exhaust temperatures. 2、What is passive regeneration? Cummins engines are designed to maximize the use of passive self-regeneration. This occurs when operating conditions maintain sufficient exhaust temperature, therefore enabling continuous oxiபைடு நூலகம்ation of the PM. Passive selfregeneration is completely transparent to the operator and does not affect the machine’s operation or performance. Cummins field test results have shown that most off-highway equipment operates at a high enough engine load factor for the Cummins Particulate Filter to self-regenerate in passive mode the majority of the time.
