chii, ivo vanosiyana sei uye kuti ungavasiyanisa sei?
Mota dzese dzemazuvano dzinouya kwatiri kubva kuEurope, USA, Japan neKorea dzakashongedzerwa nefirita uye inoshandura inoshandura. Chii, isu takambotaura pane yedu portal Vodi.su. Ngatirangarirei muchidimbu kuti kushandiswa kwezvinhu izvi zvegasi rekupedza gasi rinokubvumira kuti uchenese zvakanyanya kuburitsa kubva kune muffler kubva kune inokuvadza kemikari makomisheni uye soot.
Mumirayiridzo yemotokari dzakadaro, unogona kuverenga kuti peturu isina-lead chete yeA-92 kana A-95 inofanira kuzadzwa sehuni. Asi vatyairi vazhinji havakwanisi munyaya iyi. peturu isina lead ingasiyaniswa sei nepeturu ine lead? Ndeupi musiyano uripo pakati pazvo? Tichaedza kupa mhinduro dzemibvunzo iyi.
Lead peturu
Kuwedzera octane nhamba yemafuta pakutanga kweindasitiri yemotokari, mumwe wemakemikari akafungidzira kusanganisa peturu neakakosha ekuwedzera. Kunyanya ne tetraethyl lead. Sezvinoreva zita, musanganiswa uyu une mutobvu. Mishonga yomutobvu ine muchetura, inochetura mumhepo, uye vanhu vamene vanotanga kutambura.
Kana iwe ukafema mumhute, ipapo mhedzisiro isingagoneki yakamirira munhu:
- headaches;
- kunzwa kusanzwa zvakanaka;
- kuremara kwemaitiro ekufema;
- rufu.
Mukuwedzera, mutobvu unogara pavhu, mashizha, pamwe chete nemvura yakasvibiswa inopinda munzizi nemadziva uye ichienderera mberi neketani yekutenderera kwemvura mumasikirwo.
Mafuta ane tetraethyl lead ane njodzi kune ese mota masisitimu. Kutanga, inoputika pamwero wakaderera wekumanikidza uye pakudziya kwakaderera. Saizvozvo, kana ukaidururira mumotokari yekune imwe nyika, masaisai anovhundutsa kubva pakuparara achaparadza zvine chivimbo uye zvine hungwaru cylinder block, block head, uye piston madziro.
Kechipiri, lead inogara pamadziro epores yecatalytic converter. Nokufamba kwenguva, iyo catalyst inongofanira kuraswa kure. Hatikuyeuchidze kuti imarii pakuitsiva. Iko kune zvakare kukanganisa kunokanganisa paLambda sensor, iyo inodzora iyo okisijeni yemukati mukupedza. Mukutaura, motokari yekunze pamafuta akadaro haiperi kwenguva refu. Chechitatu, nekuda kwayo, majekiseni ejojo anokurumidza kuvharwa, uye hunhu hutsvuku hwekuputira mafomu pane spark plugs.
peturu isina lead
Chii chinonzi unleaded peturu? Chaizvoizvo, mutsauko chete kusavapo kweiyi tetraethyl lead mukuumbwa kwayo. Nekuda kwekushaikwa kwekomboni iyi, rudzi urwu rwemafuta haruna kunyatsoshanda, asi injini dzemotokari dzemazuva ano dzakangogadzirirwa kuishandisa. Kubudirira kwekupisa uye detonation kunowanikwa kuburikidza nekushandiswa kwezvinowedzera zvichienderana nedoro uye esters, iyo isina mishonga inokuvadza yakadaro yemutobvu nemamwe masimbi.
Ehe, kupisa kwemafuta asina lead kunoburitsawo huturu hune njodzi, asi mazhinji acho anozopedzisira ave mune inoshandura inoshandura uye dizeli particulate sefa. Ndiko kuti, inonyanya kushamwaridzana kune zvakasikwa. Zvakare, vagadziri vemafuta vanogara vachivandudza matekinoroji ekucheneswa kwayo kubva kune chero tsvina. Saka, kana iwe ukaisa peturu pazviteshi zvepeturu, kwavanovimbisa mafuta emhando yepamusoro, haufanirwe kunetseka zvakanyanya nezve injini yebhiza rako resimbi.
Mhando dzepeturu isina lead dzinozivikanwa kune vese vatyairi:
- A-80 - iyo yakaderera yekuchenesa mhando, yakakodzera kune yakakosha midziyo, marori, mota dzakagadzirwa neSoviet, mamwe mhando dzemidhudhudhu ine carburetor-mhando injini;
- A-92 - inodururwa mumatangi emotokari zhinji dzepamba uye dzeChinese, dzakakodzera mota dzekunze dzakaburitswa muma1990;
- A-95 - yakakurudzirwa mafuta emota zhinji dzekunze dzebhajeti uye chikamu chikuru;
- A-98 - Premium kirasi peturu yemotokari dzinodhura.
Kune, hongu, mamwe mabhureki: A-72, A-76, Ai-91, Ai-93, Ai-96. Izvo zvakakoshawo kucherechedza kuti iyo yakawanda inogoneka octane nhamba ye leaded peturu inosvika A-110. A-100, A-98+, A-102 uye pamusoro ndiwo mhando dzepeturu yemujaho, inodururwa mumatangi emota dzemitambo dzakadai seFerrari, Lamborghini, Porsche, nezvimwe.
Nenzira, mafuta emujaho anoshandiswa muFormula 1 mijaho anogona kutungamirwa kana kuburitswa.
Peturu inogona kuonekwa here kana kunhuwidza?
Chokutanga pane zvose, zvinofanira kutaurwa kuti muMoscow uye maguta makuru eRussian Federation lead peturu yakarambidzwa uye hauzoiwana mumambure ezviteshi zvegasi zvinozivikanwa. Asi kunze, iwe unogona kumhanyira mune yenhema kana musanganiswa unouraya wemhando mbiri dzemafuta.
Nzira yekuvasiyanisa sei?
Zvinoenderana neyese iripo yeRussia neyekunze zviyero, yakajairika peturu imvura yakachena, isina ruvara. Wedzera orenji kana dhayi dzvuku kune mafuta anotungamira.. Zvakare, iyo inotungamira yemukati inogona kuwonekwa nekunhuwa. Ngatingoti- peturu ye lead inonhuwa zvakanyanya uye haifadzi.
