Isevisi - iketango lesikhathi elivulekile 1,2 HTP 47 kW
Isikhathi esithile manje, amayunithi we-1,2 we-HTP asebenzise isikhala ngaphansi kwama-hood iningi labanikazi bezimoto abajabule kakhulu noma abanenhlanhla engaphansi kweqembu elikhulu le-VW. Kodwa-ke, bambalwa abantu abazi ukuthi yini ubungozi bokuqalisa injini. Ukuze ngiqale, ngincoma ukuthi ngifunde le ndatshana emaphutheni ayo namaphutha ayo ajwayelekile.
Ibhulokhi eyisisekelo ye-1,2 HTP iyi-block ka-cylinder ezine ka-1598cc efinyeziwe futhi eguquliwe.3 ngamandla angu-55 kW. Ibhande lesikhathi likhishwe ku-"isithupha" elidala elishayela i-camshaft futhi esikhundleni se-timing chain, kanye ne-hydraulic tensioner, kwakufanele inikeze ukusebenza okungenakulungiswa kanye nokuphazamiseka okuncane ekusebenzeni okuvamile kwayo yonke into. injini block. Nokho, kwakungenye indlela. Ngemva kokwethulwa kwenjini yokuqala yama-cylinder amathathu, elinye lamaphutha amabi kakhulu laqala ukuvela - ukushintsha isikhathi se-valve, okuvame ukuhlotshaniswa nokufa kweyunithi ngokwayo. Ngisho nokuthuthukiswa kwango-2007 akuzange kuyiqede ngokuphelele le nkinga. Ukuthuthukiswa okukhulu akwenzekanga kwaze kwaba maphakathi no-2009 lapho iketango lithathelwa indawo iketango elinamazinyo.
Kungani lokhu kwenzeka?
Enye yezimbangela ezivame kakhulu zokweqa ngamaketango ukushayela ngesivinini esingaphansi kwesifanele (okubizwa ngesivinini sikagandaganda) kanye iphushe noma yelule imoto. Lapho injini icishiwe, iketango liqiniswa kuphela yi-tension spring, empeleni esebenza kuphela ukushuba okwesikhashana kuze kube yilapho injini iqala ukuhamba. Ezimweni ezingavamile, imbangela nayo iqala ngebhethri efile, lapho isiqalisi singakwazi ukuthuthukisa isivinini esidingekayo sokuqalisa injini, esinikezwa yi-hydraulic chain tensioner ngokusebenzisa iphampu kawoyela, ngakho-ke iketango liqiniswa kuphela yi-spring spring. , engenawo amandla okuguqula injini ngokuphindaphindiwe ngaphandle kokusebenzisa i-hydraulic tensioner. Ngenxa yokucindezela kwentwasahlobo okunganele, futhi akunconywa ukugcina igiya libambekile lapho upaka, ikakhulukazi emithambekeni eyimiqansa. Abantu abaningi abayazi le nkinga futhi ngesibindi bashiya i-Fabia, i-Polo noma i-Ibiza yabo emithambekeni ethambile, ibhuleki ngokuqondile ngokudluliselwa, okufaka ingcindezi ohlelweni lwe-tension. Qinisekisa ukuthi usebenzisa i-hand brake, ezimweni ezimbi kakhulu - i-wedge yokulungisa ngaphansi kwesondo. Lokhu kuzogwema inkinga echazwe ngenhla.
Yini ebangela ukuthi iketanga leqe?
Uma iketanga lishibilika, kunoshintsho olusheshayo esikhathini sama-valve maqondana nama-piston. I-camshaft kancane kancane "iqhubekisela phansi" ama-valve phansi, kuqala ukungena, bese kuba yi-exhaust (amabili endabeni yama-valve angu-12 futhi eyodwa kube ama-valve angu-6, lapho kunama-valve amabili kuphela nge-cylinder ngayinye). Ngenkathi elinye ipheya linakekela ukufakwa komoya ohlanzekile, elinye, ngemuva kokushisa, lisusa amagesi okuthungela ekamelweni lomlilo. Imininingwane engaphezulu ngokusebenza kwe-valve distributor LAPHA. Ngakho-ke sigxume iketanga, isikhathi siphukile - sishintshiwe, i-piston esenjinini yehla ngemuva kokuqhuma, futhi kufanele kulandelwe ama-valve wokukhipha. Kepha lokhu akwenzeki, ngoba i-cam isivele ijikeleza ngomehluko wesigaba njengemoto. I-piston iyabuya, kodwa ngalesi sikhathi kunwetshwa ama-valve amaningana, futhi kwenzeka ukushayisana okubulalayo, okuphela ngokubhujiswa kwama-valve, ukulimala (ukubhoboza i-piston), futhi ngenxa yalokho, kulimaza injini uqobo.
Siyini isiphetho?
Izindleko zokulungisa akuzona ezishibhile, ngoba ezimweni eziningi ukulungiswa okulindelekile noma ukushintshwa kwalo lonke ucingo kufanele kucatshangwe. Ngakho-ke, asincomi ukushayela ngejubane elingaphansi kwe-1500 rpm (futhi ngenxa yokushisa ngokweqile). Ungalokothi uphushe imoto, ungaluli bese ushintsha ibhethri elibuthakathaka, abaningi abalishaja ngobuqotho nsuku zonke egumbini elingaphansi, ufake elisha elisezingeni eliphakeme ukugwema ezinye izinkinga. Sifisela wena amakhilomitha amaningi aphumelele.
