Heano maitiro ekuchenesa yako particulate firita

Diesel dzese dzazvino uye mota dze peturu dzine firita (mune peturu inonzi catalyst). Zvichienderana nemhando yemota uye dhiraivha dhizaini, mafirita emazuva ano anoshanda kubva pamazana zana kusvika zana nemakumi masere emamiromita, uye kunyangwe zvishoma nekutyaira kweguta.

Mukuita, vanove vakafukidzwa nesot. Panotsva mafuta edhiziri, zvisaririra zvehydrocarboni zvisina kupiswa zvinopinda mupombi yekuzadza, dzimwe nguva simbi dzinorema uye zvimwe zvinokachidza zvinogona kuve mune ino chiutsi.

Sefa mudziyo

Iwo mafirita ane zinga rehuchi-rakaumbwa ceramic chimiro chakaputirwa nesimbi dzakakosha senge platinamu (yakanyatsopetwa). Maseru anopindirana nekuunganidzwa kwezvimedu, uye kunyangwe otomatiki kuchenesa kana uchityaira mumugwagwa mukuru nekumhanyisa (tembiricha iri mukukwidza inokwira, uye sosi isina kupiswa kubva patembiricha inopisa) inogona kusabatsira.

Mari dzakadai dzinogona kukonzeresa kurasika kwesimba (nekuda kwekuwedzera kuramba), kana kutodzivirira mota kutanga zvachose.

Kuchinja kana kuchenesa?

Vazhinji vagadziri nevatengesi vanopa zano rakakwana rekunatsiridza DPF. Zvichienderana nebasa uye nemodheru modhi, iyo huwandu inogona kukwira kusvika ku4500 euros. Semuenzaniso - chete firita yeMercedes C-Kirasi inodhura mazana matanhatu emadhora.

Zvisinei, kutsiva hakuwanzo kuve kuri madikanwa. Kazhinji mafirita ekare anogona kucheneswa uye kushandiswazve. Iri sevhisi rinodhura kutenderera mazana mana emaeuro. Zvisinei, haisi nzira dzose dzekuchenesa dzinokurudzirwa.

Nzira dzekuchenesa

Imwe nzira yekuchenesa mafirita ndeyekupisa zvidimbu apo uchidziisa chikamu muchoto. Iyo catalyst inoiswa muchoto iyo inodziya zvishoma nezvishoma kusvika ku600 degrees Celsius uye ndokuzononoka zvishoma nezvishoma. Guruva uye sosi zvinoshambidzwa nemhepo yakamanikidzwa uye chando chakaoma (solid carbon dioxide, CO2)

Mushure mekuchenesa, iyo firita inowana zvimwe zvakafanana zvivakwa senge nyowani. Nekudaro, maitiro aya anotora anosvika kumazuva mashanu sezvo achifanira kudzokororwa kakawanda. Mutengo unosvika hafu yemutengo wefaira nyowani.

Imwe nzira yeiyi nzira ndeye kuchenesa yakaoma. Mariri, zinga reuchi rinosaswa nechimwe chinhu chakakosha. Iyo inorwisa zvakanyanya sosi asi haina kunyatsoita kupokana nemamwe madhipatimendi. Nechikonzero ichi, kufuridza nemhepo yakamanikidzwa kuchiri kudikanwa, izvo zvinogona kukuvadza chimiro cheuchi.

Pakuchenesa, firita inogona kutumirwa kune nyanzvi kambani, uye kuchenesa kunotora mazuva akati wandei. Nekudaro, 95 kusvika 98 muzana yemasefa anogona kushandiswazve. Maitiro aya anogona kutenga kubva pamazana matatu kusvika mazana mana emadhora.

Mibvunzo nemhinduro:

Nzira yekunzwisisa sei kuti iyo particulate sefa yakavharwa? Nokuda kweizvi, pane chiratidzo pane yakarongeka (injini), kushandiswa kwemafuta kuchawedzerwa, kufambisa kunopera (simba remotokari richaderera), utsi huzhinji huchabuda mupombi yekupedza, uye injini icharidza mhere panguva yekushanda. .

Sefa inocheneswa sei? Mune mamwe mamodhi emota, otomatiki kuvandudzwa kweiyo particulate sefa inoshandiswa. Kana ichivharika, mafuta kana urea inopfapfaidzwa pamatrix, iyo inotungidza mukati mesefa, ichibvisa soot.

Iyo particulate filter regeneration inotora nguva yakareba sei? Zvinoenderana nekuti mota inoshandiswa sei. Semuenzaniso, pasi pemamiriro asingatenderi sefa kudziya kusvika kune yaunoda dhigirii, mutongi anovhura pfapfaidzo yemafuta ekuwedzera musefa uye anovhara EGR valve.
