Basa - kuvhura nguva cheni 1,2 HTP 47 kW
Kwenguva yakati ikozvino, 1,2 HTP mayunitsi anga achitora nzvimbo iri pasi pehodhi dzevazhinji vane rombo rakanaka kana vashoma varidzi vemota vari veiyo hofori VW boka. Nekudaro, vashoma vanhu vanoziva kuti njodzi dzekutanga injini chii. Kuti utange, ini ndinokurudzira kuverenga iyo chinyorwa pane ayo akajairika zvikanganiso uye kukanganisa.
Iyo yekutanga chivakwa cheiyo 1,2 HTP yakapfupiswa uye yakagadziridzwa 1598cc ina-humburumbira injini chinogumbura.3 ine simba re55 kW. Bhandi renguva yakabviswa kubva kune yekare "nhanhatu" iyo yakatyaira camshaft uye yakatsiviwa neketani yenguva, iyo, pamwe chete ne hydraulic tensioner, yaifanira kupa kushandiswa kwekuchengetedza-kusununguka uye kupindira kuduku nekushanda kwese kwese. injini block. Zvisinei, zvakanga zvakasiyana. Mushure mekutangwa kwejini yekutanga matatu-cylinder, chimwe chezvikanganiso zvakakomba zvakatanga kuoneka - kushanduka kwevhavha nguva, kazhinji inosanganiswa nekufa kweiyo unit pachayo. Kunyangwe kukwidziridzwa kwa2007 hakuna kubvisa zvachose dambudziko iri. Kuvandudzwa kukuru hakuna kuitika kusvika pakati pegore ra2009 apo cheni yakatsiviwa neketani ine mazino.
Nei izvi zvichiitika?
Chimwe chezvikonzero zvinonyanya kukonzeresa kusvetuka kwecheni kutyaira zvine spidhi isingasviki (inonzi tirakita kumhanya) uye pusha kana kutambanudza mota. Kana injini yadzimwa, cheni inongodzvinyirirwa chete nechitubu chekunetsana, icho chinongoshanda chete kunetsa kwechinguva kusvika injini yatanga kufamba. Muzviitiko zvisingawanzoitiki, chikonzero chiri kutanga nebhatiri rakafa, apo mutangi asingakwanisi kukudziridza kukurumidza kunofanirwa kutanga injini, iyo inopiwa ne hydraulic chain tensioner kuburikidza nepombi yemafuta, saka ketani inosimbiswa chete nechitubu chekunetseka. , iyo isina kusimba zvakakwana kuti idzokorore kushandura injini pasina kushandisa hydraulic tensioner. Nekuda kwekusakwana kwekumanikidzwa kwechirimo, hazvikurudzirwewo kuchengeta giya rakabatikana paunenge uchipaka, kunyanya pamateru. Vanhu vazhinji havazivi nezvedambudziko iri uye vakashinga vanosiya yavo Fabia, Polo kana Ibiza pamateru akapfava, akabhurwa zvakananga nekutapurirana, izvo zvinoisa kudzvanywa pahurongwa hwekushushikana. Iva nechokwadi chekushandisa bhureki remaoko, muzviitiko zvakanyanyisa - wedge yekugadzirisa pasi pevhiri. Izvi zvinodzivirira dambudziko rinotsanangurwa pamusoro apa.
Chii chinokonzeresa cheni kusvetuka?
Kana cheni ikatsvedza, pane iko kuchinjika munguva yevhavha maererano ne piston. Iyo camshaft zvishoma nezvishoma "inosundira" mavhavha pasi, kutanga kudyiwa, kozoti chiutsi (zviviri mune gumi nemaviri mavharuvhu uye imwe iri yematanhatu mavharuvhu, kana paine maviri chete mavhavha pasirinda). Nepo imwe peya ichitarisira kudyiwa kwemhepo nyowani, imwe, mushure mekutsvaira, inobvisa gasi remhepo kubva mukamuri yemoto. Rumwe ruzivo nezve iyo vharuvhu muparidzi mashandiro HERE. Saka isu takasvetukira pacheni, iyo nguva yakanga yadambuka - yakachinjwa, iyo pisitoni iri muinjini inofamba ichidzika pasi mushure mekuputika, uye mapaipi emagetsi ekushandisa anofanira kutevera. Asi izvi hazviitike, nekuti iyo cam iri kutotenderera muchikamu musiyano senge mota. Pisitoni inodzoka, asi panguva ino mavhavha akati wandei anowedzera, uye kukonzeresa kunouraya kunoitika, uko kunopera nekuparadzwa kwemavharuvhu, kukuvara (pisitoni kubaya) uye, semhedzisiro, kukuvadza kune injini pachayo.
Ndeipi mhedziso?
Mari dzekugadzirisa hadzisi dzakachipa zvakanyanya, sezvo muzviitiko zvakawanda kugadziridzwa kwakanyanya kana kutsiva kwechigadzirwa chose kunofanirwa kufungidzirwa. Naizvozvo, isu hatikurudzire kutyaira nekumhanyisa pazasi pe1500 rpm (zvakare nekuda kwekunyanyisa). Usambofa wakasunda mota, usatambanudze uye kutsiva bhatiri risina kusimba, iro vazhinji vakatendeseka zuva rega rega muchikamu chepasi, neimwe nyowani, yemhando yepamusoro kudzivirira mamwe matambudziko. Tinokuda iwe makiromita mazhinji akabudirira.
