Diesel Oxidation Catalysts

Say diesel oxidation catalyst (DOC) et kabiangan na diesel exhaust systems manlapu nen inletneg iray totontonen pian limitaan so karakel na makaderal ya emissions ya ipapaway ed kaliberliber manlapud diesel engines, saya so catalytic converter ya ginawa parad amin a klase na diesel engines tan kagawaan pian nabawasan so Carbon Monoxide (CO), Hydrocarbon (HC) tan Matter emissions, carbon monoxide (CO) tan hydrocarbons ya magmaliw ya carbon dioxide (CO2) tan danum. Say manunan gagala na DOC et say panag-oxidate na CO, saray ag apoolan ya hydrocarbon, tan NO, bangta say aktibon hydrocarbon oxidation et nayarin usaren met pian makagawa na saray exotherms ya nakaukolan parad saray downstream components.

1) Nababawasan so SOF emission na anggad 90%

2) Nababawasan toy CO,HC emission na anggad 75%, sarag ton i-oxidize so CO tan HC ya magmaliw ya CO₂ tan H₂O

3) Nasebel so oxidation ed proseso na S tan nabawasan so inkaporma na sulfate

4)Mabmablin metal tan washcoat ya atagey so tapew to.

5)Atagey ya inkaapag-apag na mablin metal.l.

6)Abeban temperatura na liwawa.

7)Maong ya pankakasakey na wash-coat tan say substrate ya walay netty ya istruktura to.

8)Maong ya panag-yegyeg.

9)Ikasakey so EGR system pian natulongan so nanduruman luluganan ya makapenek ed Euro II o Euro III.
