● Gwo sifas espesifik: pou asire aksè konplè a gaz echapman an avèk katalis la.
● Absòpsyon dlo ki estab: pou asire katalis la byen kole sou sifas sipò katalis la.
● Chofaj: apre motè a fin demarre, tanperati transpòtè a ka rive nan tanperati aktivasyon katalis la nan tan ki pi kout posib.
● Rezistans echapman ki ba: rezistans echapman motè a piti, pou asire ke sa pa afekte pèfòmans motè a.
● Segondè fòs: anviwònman fonksyònman transpòtè katalis la se nan machin ki gen aksidan, kidonk transpòtè katalis la dwe gen gwo fòs san li pa sibi domaj ekstèn.
● Bon asanblaj: konpayi transpò a se yon pyès asanblaj echapman, sèlman yon bon aparans ak dimansyon egzak ka asire yon asanblaj pafè.

1. Lafimen ap koule anndan
Gaz echapman dyezèl antre nan SiC DPF la, ki se yon filtè seramik pore, ki koule nan miray, ki fèt ak carbure Silisyòm.
2. Swi bloke
Patikil swi (lafimen nwa) yo kenbe nan mi ak porositë filtè yo, pandan gaz pwòp la ap pase.
3. Rejenerasyon boule swi
Lè swi akimile, tanperati echapman ki wo oswa enjeksyon gaz la ogmante tanperati filtè a.
Swi ki bloke a boule pou tounen CO₂ ak vapè dlo, sa netwaye filtè a.
4. Kontwòl emisyon kontinyèl
Pwosesis la repete: filtè a kenbe swi → li rejenerasyon → li kenbe gaz echapman an pwòp pou satisfè estanda emisyon yo.
