Particle emission characteristics of DPF regeneration from DPF regeneration bench and diesel engine bench measurements

Study on characteristics of particulate emission of diesel aftertreatment with reciprocating flow

“…A number of studies have been conducted to investigate the influence of regeneration conditions on the PM emission performance of DPF 23‐25 . The various mechanisms obtained from these investigations could reasonably explain the increase phenomenon of PM emission from DPF during regeneration 26‐30 . But these past investigations main focused on the regeneration performance of traditional unidirectional flow DPF.…”

Eficácia de aditivo via tanque para combustível diesel na limpeza dos sistemas de pós tratamento

“…Porém, este filtro precisa ser regenerado toda vez que apresentar limites próximos à saturação. Conforme (MENG;CHEN;FANG et al, 2020), a sua não regeneração provoca o aumento de pressão no sistema, com a perda de potência do motor e, em casos extremos, a parada do veículo. A regeneração pode ocorrer de forma passiva, onde os gases de escape atingem temperaturas mínimas e possibilitam a reação de oxidação do material particulado, que basicamente corresponde a resíduo de carbono produzindo CO2 e água.…”

Thermogravimetric analysis of soot combustion in the presence of ash and soluble organic fraction

“…23 Therefore, a great deal of effort has been devoted to investigating the regeneration process for the extension of DPF life time and emission reduction. 24,25 Initially, it was reported that PM mainly contains dry soot, SOF, sulfates, ash, and moisture. 26 Similarly, Mohankumar et al 27 proposed that PM could be divided into a soluble and insoluble organic fraction, and soot accounts for the major proportion.…”
