Sei Matatu-nzira Catalytic Vashanduri vasingadhure Madhora Matatu?

Tinoziva kuti matatu-nzira inoshandura inoshandura kazhinji inotanga kubva mukutadza kwemotokari.Hazvisi zvakachipa kuchinja imwe itsva isingasviki mazana mashoma eyuan kana kudarika zviuru gumi zveyuan. Sei tisingataure nezvenzira nhatu dzinokurudzira nhasi? Sei ichidhura? Nzira yekushandisa sei mari shoma uye kuchinja zvishoma zvakashata?

Zvazvinoita

Tinogona kufunga nezvenzira nhatu dzinoshandura shanduko se"Environmental protection device" pamotokari. Mumakore achangopfuura, kusvibiswa kwemhepo kwave kuchiwedzera kutariswa, uye miitiro yeChina yenyika nhanhatu yekubudisa mhepo yakakwira. Three-way catalytic converters dzatonyanya kukosha-muchidimbu, kufema magasi anokuvadza uye kufemera asingakuvadzi. Iyo yekuchenesa mumiriri mune matatu-nzira inokonzeresa inosimudzira basa reCO, HC uye NOx mumotokari inopedza gasi, zvichiita kuti ienderere pane imwe redox uye pakupedzisira ive isina njodzi gasi.

Sei Zvichidhura

Vanhu vakachinja vanoziva kuti matatu-nzira catalytic converters anodhura chaizvo. Dzimwe motokari dzinodhura makumi ezviuru zveyuan, iyo inogona kuita chikamu chimwe chete mugumi chemutengo wemotokari. Pane zvikonzero zviviri zvikuru nei ichidhura.

Imwe imhaka yekuti ine simbi dzinokosha. Iyo nzira nhatu-catalyst ine goko, damping layer, mutakuri uye catalyst coating. Masimbi asingawanzo akadai sePt (platinum), Rh (Rhodium), PD (palladium) uye zvisingawanzo pasi simbi zvinosanganisira CE (cerium) uye LA (lanthanum) anoshandiswa mune inokonzeresa-yakavharwa zvinhu. Ndicho chikonzero ivo vanodzokorora matatu-nzira catalytic converters.Icho chikonzero zvakare nei vatyairi vekare vachibvisa yekare-nzira nhatu inoshandura inoshandura pavanoshandura itsva.

Chechipiri, nokuti kugadzirwa kwepamusoro-soro zvinodiwa. Pamusika unogona kugadzira emhando yepamusoro matatu-nzira inoshandura inoshandura vagadziri, saka zvakare yakasimudza mutengo wetatu-nzira inoshandura inoshandura. Ehe, kune yakaderera-inodhura matatu-nzira catalytic converters, asi isu tinofanirwa kutarisisa kune mhando yenzira nhatu-catalytic converters haizokonzerese simba remotokari, kushandiswa kwemafuta uye zvimwe zvakaipa zvinokonzeresa, asiwo kunokanganisa kuongororwa kwemotokari. . Uye hupenyu hwebasa huchapfupiswa zvikuru, mari yose haisi duku.

Kukundikana & Chikonzero

Izvo zvinowanzoitika zvikanganiso zvetatu-nzira catalyst ndezvi:

1.Mwenje wemwenje unovhenekera, iyo general fault code ndeye P0420 kana P0421 (inomiririra yakaderera kutendeuka kushanda zvakanaka).

2.Gasi rinopisa rinopfuura chiyero, chinokanganisa motokari yekuongorora.

3. Ichaita kuti motokari iwedzere zvishoma nezvishoma, isina simba.

4.Zvimwe zvinetso, zvakadai sezwi risina kujairika, kunyunguduka, kupatsanurwa, kudonha.

Pane zvikonzero zvitatu zvekukundikana uku:

Yokutanga ndiyo kunaka kwehuni, mafuta mumutungamiri uye sarufa uye mafuta mu phosphorus uye zingi zvichakonzera kukuvadza kukuru kune matatu-nzira catalyst.Lead ndiyo inonyanya kukuvadza. Dzimwe ongororo dzinoratidza kuti kunyangwe bhokisi repeturu rine lead rakashandiswa, zvinokonzeresa kutadza kukuru kwetatu-nzira catalytic converter. Asi nyika yedu yakatoona mota peturu isina unleaded, izvi zvatoda kuti usanetseka.

Chechipiri kufunga kukanganisa kweinjini, senge injini isina moto, yakawandisa kana yakaonda musanganiswa, kupisa mafuta einjini, zvichingodaro, zvichavewo nemhedzisiro yakakomba pane matatu-nzira inoshandura inoshandura.

Chekupedzisira ndihwo hupenyu hwekugadzira, iyo mota inoshandisa matatu-nzira inoshandura inoshandura hapana chakakomba mhosva, inogona kushandiswa kuchembera kwayo kwechisikigo, shamwari dzemotokari dzinochengetedza dambudziko rakawanda.

Nzira Yokudzivirira Sei

Izvo zvakakosha uye zvinodhura, isu tinowedzera sei hupenyu hwenzira nhatu-catalyst?

Nzira yakananga ndeyekuchenesa nguva dzose, iyo yakakurudzirwa yekuchenesa kutenderera ndeye 40-50,000 km. Kusarudzwa kwemafuta kuzadzisa zvinodiwa nemotokari yepakutanga, usarega mwero wemafuta uchidarika muganho wegeji yemafuta. (mamwe maVW modhi ane"Oiri yakawandisa mukamuri yeinjini inokuvadza catalytic reactor" chiziviso, vatyairi veVW vanogona kuterera)

Uyewo sarudza mafuta kuti asangane nezvinodiwa zvemotokari, usapera mafuta, sezvinobvira kuchengetedza mafuta akakwana. Mafuta ekuwedzera haagoni kushandisa manganese, zvigadzirwa zvesimbi.
