Mashandiro EExhaust Systems Anoshanda
Zviri mukati
Zvose zvinotanga muinjini
Kuti unzwisise kuti kubuda kwemotokari kunoshanda sei, zvakakosha kuva nekunzwisisa kwekutanga kwejini yose. Injini yekupisa yemukati muchimiro chayo chakareruka ipombi huru yemhepo. Inounganidza mumhepo, inoisanganisa nemafuta, inowedzera spark, uye inopisa musanganiswa wemhepo-mafuta. Izwi rakakosha apa ndere "kupisa". Nemhaka yokuti nzira inoita kuti motokari ifambe inobatanidza kutsva, pane tsvina, sezvakangoita tsvina inobatanidzwa nemhando ipi zvayo yekupisa. Kana moto ukabatidzwa pachoto, marara acho utsi, chin’ai nemadota. Kune yemukati combustion system, izvo zvinoraswa magasi, kabhoni particles uye diki diki dzakamiswa mumagasi, pamwe chete anozivikanwa seanopedza gasi. Iyo exhaust system inosefa marara aya uye inovabatsira kubuda mumotokari.
Nepo masisitimu emazuva ano ekupedza simba akaomarara, izvi hazvina kugara zvakadaro. Yakanga isati yasvika pakupfuura kweClean Air Act ye1970 iyo hurumende yakave nekwaniso yekuisa huwandu uye rudzi rwemagasi emhepo akabudiswa nemotokari. Iyo Yakachena Air Act yakagadziridzwa muna 1976 uye zvakare muna 1990, ichimanikidza vagadziri vemotokari kugadzira mota dzinosangana neyakaomesesa emission standard. Mitemo iyi yakavandudza hunhu hwemhepo munzvimbo zhinji dzakakura dzeUS metropolitan uye yakatungamira kune exhaust system sezvatinoziva nhasi.
Exhaust system zvikamu
Exhaust valve: Ivhavha yekupedza iri mucylinder musoro uye inovhura mushure mekupisa kwepiston.
Piston: Iyo pistoni inosundira magasi anopisa kubva mukamuri rinopisa uye kupinda mune yakawanda yekuburitsa.
Exhaust yakawanda: Iyo exhaust manifold inotakura zvinobuda kubva papiston kuenda kune inoshandura inoshandura.
Anogadzirisa chinja Iyo catalytic inoshandura inoderedza huwandu hwehupfu mumagasi ekubuda kwekuchenesa.
Futi yekudonha Iyo pombi yekuburitsa inotakura zvinobuda kubva kune inoshandura inoshandura kuenda kune muffler.
Mufudzi Iyo muffler inoderedza ruzha rwunogadzirwa panguva yekupisa uye exhaust emissions.
Chaizvoizvo, iyo exhaust system inoshanda nekuunganidza marara kubva pakupisa uye wozoifambisa kuburikidza nenhevedzano yepombi kuenda kunzvimbo dzakasiyana dze exhaust system. Iyo inopera inobuda pakuvhura yakagadzirwa nekufamba kwevhavhavha uye inotungamirirwa kune yakawanda yekubuda. Mune manifold, magasi ekupedza kubva kune imwe neimwe yemasilinda anounganidzwa pamwe chete obva amanikidzwa kupinda mushanduri inoshandura. Mune inoshandura inoshandura, kupera kunocheneswa zvishoma. Nitrogen oxides inoputsika muzvikamu zvadzo, nitrogen neokisijeni, uye okisijeni inowedzerwa kucarbon monoxide, zvichiita kuti isanyanya muchetura asi ichiri nengozi kabhoni dhaikisaidhi. Pakupedzisira, pombi yepombi inotakura zvinobuda zvinochenesa kuenda kune muffler, izvo zvinoderedza ruzha runoperekedzwa kana magasi anobuditsa mumhepo.
Injini dzemagetsi
Pave nekutenda kwenguva refu kuti kupera kwedhiziri kwakasviba zvakanyanya kupfuura peturu isina lead. Chiutsi chitema chakashata chiya chinobuda murori hombe chinopisa chinotaridzika uye chinonhuwa zvakanyanya kupfuura chinobuda mumotikari yemota. Zvisinei, mitemo pamusoro pekubudiswa kwedhiziri yakave yakaoma zvikuru mumakore makumi maviri apfuura, uye kazhinji, seyakashata sezvazvingaratidzika, kupera kwedhiziri yakachena seyemotokari yemotokari. Diesel particulate filters inobvisa 95% yehutsi hwedhiziri (kwakabva: http://phys.org/news/2011-06-myths-diesel.html), zvinoreva kuti unoona soot yakawanda kupfuura chero chinhu chipi zvacho. Muchokwadi, kupera kweinjini yedhiziri ine kabhoni dhaikisaidhi shoma pane kupera kweinjini yegesi. Nekuda kwekutonga kwakasimba kwekubuda kwedhiziri pamwe nekuwedzera mamaira, injini dzedhiziri dzinonyanya kushandiswa mumotokari diki, kusanganisira Audi, BMW uye Jeep modhi.
Zviratidzo zvinowanzoitika uye kugadzirisa
Exhaust system kugadzirisa kwakajairika. Kana paine zvikamu zvakawanda zvinofamba mune imwe inogara ichimhanya sisitimu, kugadzirisa kwakawanda hakudzivisiki.
Yakatsemuka exhaust yakawanda Mota iyi inogona kunge iine mutsindo wakatsemuka unobuda seruzha rwekukwenya padivi peinjini inonzwika sewachi hombe.
Yakashata Donut Pad: Pachavewo neruzha rwekushereketa, asi izvi zvinowanzonzwika kubva pasi pemota kana mutakuri akagara mumotokari akavhura gonhi.
Yakavharwa catalytic converter: Ichazviratidza sekurasikirwa kwakanyanya kwesimba uye kunhuhwirira kwakasimba kwechinhu chakatsva.
Rusty exhaust pombi kana muffler: Ruzha rwekupopota rwunobuda mumuffler ruchawedzera zvinonzwika.
Yakanganisa O2 sensor: Tarisa Engine light pane dashboard
Modernization of exhaust system yemotokari
Pane akati wandei ekusimudzira anogona kuitwa kune exhaust system kuvandudza mashandiro, kuwedzera ruzha, uye kunatsiridza mashandiro. Kubudirira kwakakosha pakufamba zvakanaka kwemota uye izvi zvinokwidziridzwa zvinogona kuitwa nemakanika akasimirirwa anozoodha kutsiva exhaust system zvikamu zvinoenderana neayo ekutanga pamota. Tichitaura nezvekuita, kune exhaust masisitimu anogona kuwedzera simba remotokari, uye mamwe anogona kutobatsira nekushomeka kwemafuta. Kugadzirisa uku kunoda kuisirwa dhizaini nyowani. Kana toreva nezvokunzwika, ruzha rwemotokari runogona kubva paruzha rwakarovedzeka kuenda paruzha runogona kurondedzerwa zvakanakisisa soruzha, kusvikira kupfundo apo kutinhira kwemotokari kunoenzaniswa nokutinhira. Usakanganwa kuti kana iwe uchikwidziridza exhaust yako, iwe unofanirwa kukwidziridza kutora kwako zvakare.
