Injini isinganzwisisike inogogodza

Usati watenga motokari yakashandiswa, unofanira kusarudza kana uchida kutsiva hydraulic valve lifters. Kana tikaita nokukurumidza, mari yacho ichava yakaderera.

Mota dzakashandiswa kazhinji dzine mileage inodarika 100 kilometres. km uye zvinotendwa kuti peturu yavo injini inogona kumira zvakanyanya. Ichokwadi, usati watenga zvakakosha kusarudza kana hydraulic distributors inoda kuchinjwa.  

Kana tikapindura nokukurumidza, mari ichava yakaderera uye kusaregeredza kunogona kutungamirira kukugadzirisa kukuru uye, zvinosuruvarisa, mari yakakwirira. Hydraulic valve lifters zvakanyanya Injini dzakawanda dzemazuva ano dzinoshandisa zvinodaidzwa kuti hydraulic valve lifters, izvo zvinoita kuti kushanda kwemotokari kuve nyore uye kusingadhuri.

Iko kuvonga kwavari kuti hapana chikonzero chekugadzirisa nguva nenguva mavharuvhu. Basa remotokari rinokurumidza uye rakachipa panguva imwe chete. Iyo pusher inoiswa pakati pe camshaft nevhavha uye basa rayo nderekugadzirisa zvakare mutambo wevharuvhu unokonzerwa nekupfeka kwezvikamu zvinopindirana.

Pusher durability

Injini yemafuta inoyerera kuburikidza nematepi uye nekudaro inonzwa zvakanyanya kune kunaka kwemafuta anoshandiswa. Hunhu husina kunaka kana kusarudzwa kwakashata kunogona kukuvadza ichi chaicho uye chakapfava chinhu nekukurumidza. Mamiriro akafanana achaitika kana nguva pakati pekuchinja kwemafuta yakawedzera zvakanyanya. Hupenyu hwebasa hwevasundi hunosiyana, asi zvinogona kufungidzirwa kuti paavhareji inenge 150 km. Ehe, hazvishamisi kuti ma pushrods anoshanda nemazvo kunyangwe mushure mekumhanya kwe300 50. km, uye zvinoitikawo kuti mushure memazana zviuru zvishanu zvichave nekodzero yekutsiva.

Nzira yekuziva sei kukanganisa?

Kukuvadzwa kwezvinosimudza vharafu kunogona kuratidzwa neruzha runobva pedyo nevhavhavhavha. Uku kugogodza kwakajeka uye kwesimbi, semuenzaniso, mune yakawandisa valve clearance. Muchikamu chekutanga chekusashanda zvakanaka, vanosundidzira vanoita ruzha nguva pfupi mushure mekutanga injini, uye zvino vanonzwika nguva dzose. Kana ruzha rukanyangarika pakakwirira rpm, chinogona kunge chiri chiratidzo chekuti kudzvanywa kwerubrication system kwakadzikira. Kutsiva imwe chete pushrod kunogona kusashanda, sezvo zvakanyanya kuoma kuwana yakakuvara (kunyanya kana iri 16-vharuvhu injini). Kana ma pushers achidhura, saka mushure mekunyatsoteerera injini, vanogona kungotsiviwa, semuenzaniso, pane imwe cylinder. Zvisinei, kana ma pushrods asingadhuri, zvakakodzera kuti atsive ose kamwechete, nokuti hupenyu hwevamwe hunenge huri kuuya kumagumo. Neiyi nzira, isu tichadzivirira zvisina kufanira inodzokororwa mari yebasa. Mutengo wekutsiva unosiyana zvakanyanya uye zvinoenderana nekureruka kwekuwana kune vanosundidzira uye mutengo wevasundi pachavo.

Ruzha rwekumhanyisa nguva haisi mhosva chete kune vanosundidzira. Inogonawo kukonzerwa nekamshaft yakasakara kana kuderera kwemafuta kunokonzerwa, semuenzaniso, nekusarudzwa kwemafuta asina kunaka (kushandiswa kwemafuta kwakaderera).

Ndiani anoshandisa pushers

Hydraulic tappets anoshandiswa pahuwandu hweinjini nhasi. Asi, hongu, kune zvisizvo. Sechinyakare, Honda neToyota havashandise hydraulic regulation, uye VW yave nenguva ichichinjira kumutemo wakadaro mumainjini ese, seOpel, Mercedes, BMW uye Daewoo (kunze kwaTico naMatiza).

Izvo zvakasiyana nemainjini ekare. Iyo yakawanda yakawanda yemayuniti ane mavharuvhu mana pahumburumbira inogadziriswa ne hydraulically. Izvo zvakasiyana ndezvimwe injini dzeFord neNissan, umo kubvumirwa kunotungamirirwa nemaitiro echinyakare. Mumotokari dzeFrance, zvinogona kufungidzirwa kuti kana injini yepetroli iri maviri-vharuvhu, ipapo mapundu anogadziriswa nemaoko, uye mana-vharuvhu - hydraulically. Izvo zvakafanana zvinogona kufungidzirwa muFiat kunetseka, kunyange mune dzimwe nguva zvakasiyana.

Hapana ma hydraulic pushers

Manually kugadzirisa vharafu nailing iri nyore uye dzimwe nguva zvese zvaunoda i feeler gauge, standard wrench uye screwdriver. Kune rumwe rutivi, mumajini akawanda, kugadzirisa kucheneswa kwakakomba, kunotora nguva (kusvika kumaawa masere) uye kushanda kunodhura nekubviswa kwebhandi renguva uye shafts uye kutsiva zvimwe zvinhu. Mutengo wekugadzirisa unobva pa8 kusvika ku30 PLN, zvichienderana nehuwandu hwekuoma. Kuwanda kwekugadzirisa backlash kunosiyana kubva ku500 kusvika ku10 zviuru. km. Panyaya yekuwedzera mafuta negesi, zvinokurudzirwa kutarisa backlash kakawanda, nokuti mumajini akawanda egasi kudzoka kunoderera nokukurumidza. Uye kushaikwa kwekutamba kunokonzera kurasikirwa kwesimba, uye kunogonawo kukuvadza zvakanyanya injini.
