Chii chinonzi CATALYTIC convert

All ano motokari chiutsi hurongwa zvinosanganisira CATALYTIC convert. mudziyo ichi chakagadzirirwa kuderedza choutsi ose zvinokuvadza kubva chiutsi magasi kuti mhepo. The CATALYTIC convert rinoshandiswa sezvo Diesel simba dzakabatana, uyewo peturu. Chigaro chake kana pakarepo seri chiutsi siyana, kana zvakananga mafuro. The neutralizer kuti chiutsi magasi rinosanganisira mutakuri Unit, iro kumbogadzirwa kuti mudziye dzimba.

mudziyo

Huru chaikosha ichaongororwa chaivharidzira mutakuri. Wakaitwa kubva refractory zvedongo. The masikirwo chidhina kwakadaro unotora munhu muzvizhinji masero longitudinal, substantially kuwedzera nzvimbo kuonana chiutsi magasi. pamusoro wavo zvinenge zvakazara chaiyo zvinhu, catalysts (palladium, Platinum uye rhodium). With zvinhu izvi, pane kumhanyisa nemakemikari.

Palladium uye Platinum ndidzo oxidation tiwedzere. Vanopa oxidation pamusoro Mahydrocarbon uye, naizvozvovo, kusimudzira kutendeuka carbon monoxide, carbon dioxide inobvisa uye mvura mhute. A rutapudzo tiwedzere ndiyo rhodium. Zvinonzi inoshandiswa kuderedza senitrogen oxides kupinda isingakuvadzi senitrogen. Zvakaratidza kuti mhando nhatu catalysts ari chiutsi magasi ipfupi zviri zvitatu inokuvadza dzakasiyana zvinhu. Saka, zano yakadaro inonzi-nzira nhatu CATALYTIC convert.

keriya Block yaiva resimbi dzimba. Pakati pavo hakuna kupisa-insulating rukoko. Nokuva gombedzero muviri inzira yakachena Switch.

Vakarongeka mudzimu mudziyo mune mubvunzo zvasvika panguva tembiricha kuti ³⁰⁰ ° C, ipapo inenge 90 muzana yanonoka zvinokuvadza (nokuti convert ichi CATALYTIC iri yakaiswa pakarepo seri chiutsi zhinji).

Features

The catalysts chaizvo vanobudirira mukuderedza chiutsi gasi toxicity uye nokudaro tine anongoda hapana zvainoita injini simba uye huni rinodyiwa. With shure mudziyo uyu kumanikidzwa inowedzera zvishoma somugumisiro iyo motokari simba chikwata anorasikirwa 2-3 litres. a. Tichingotarisa chiutsi tiwedzere hunogona kugara nokusingaperi, nokuti simbi anokosha munguva nemakemikari kupedzwa. Zvisinei, sezvo tsika inoratidza upenyu mano aya rine parinogumira.

Somuenzaniso, mumwe achimhanya zvinokonzera kukundikana converters - kunyatsogadzikana zvedongo masero, kubva unopinza kuzungura (kana motokari iri kumhanya anorovera, rikawira pothole kana kunyange muviri chirknet chinhu tiwedzere) inogona kuparadzwa, iyo inosvitsa kukundikana akati mudziyo. Zvino isu akatanga kuonekwa converters, uyo pane zvedongo - simbi monolith. Vanonyanya husingakwanisi kukuvara. Chimwe chikonzero kukundikana CATALYTIC convert - ndiye mafuta. Leaded peturu mupfumi tetraethyl kutungamirira kuti "pickle" pose masero. Somugumisiro, siyana zvose kupururudza. Muvengi inotevera ndiyo anowedzera Kuronga zvakaipa mafuta. Saka, musanganiswa ine yakawanda Mahydrocarbon, kuparadza zano, uye chinoita unopinza murombo overheating, izvo zvingaita kuti kuparadzwa monolith. Haidereri ngozi uye unopinza tembiricha kuchinja, akadai kana motokari anopinda gandwa. Kunogona kukuvadza zvedongo.

Kazhinji, ari CATALYTIC convert uyewo mamwe mashandiro sei kushanda ezvinhu.
