I-VAZ-2114, i-camshaft sensor: idivaysi, isimiso sokusebenza kanye nokungasebenzi kahle

Emotweni iVAZ-2114 inzwa ye-camshaft idlala indima ebalulekile. Ukuze injini eqondile nokushisa, kunamadivayisi amaningi axhunyiwe nge-unit control unit. Izinzwa ezengeziwe ezinjini ze-injini, kuzosebenza kangcono, ukusetshenziswa kwephethiloli kanye namandla aphezulu kuyoba ngaphansi. Ngokokuqala ngqa kwi-VAZ-2114 imodeli ye-camshaft sensor efakwe ngo-2007. Ngaphambi kwalokhu senze ngaphandle kwalo. Kodwa kuyini inzuzo yokuyisebenzisa? Lo mbuzo kufanele ufundwe ngokuningiliziwe.

Iyini inzwa ye-camshaft?

I- capsha position position , okuyinto i-VAZ-2114 inayo, idivayisi ehlola isimo se-valve (evulekile noma evaliwe). Ibuye ibizwe ngokuthi inzwa yesigaba. Leli gama libuye lilungile. Ngakho-ke, ingasetshenziswa futhi. Idivayisi ifakwe njengezimoto eziyi-eight valve (enekhamera eyodwa) ne-valve engu-16 (ene-camshafts amabili). Umsebenzi wakhe usekelwe emthethweni weHholo - ngendlela efanayo nakwabanye abasabalalisi abashintshayo. Iminye imisebenzi kuphela enenzwa ye-camshaft (VAZ-2114). Izimpawu zenkinga zizoxoxwa ngezansi.

Kukhona amazinyo ku-camshaft. Ibanga phakathi kwabo lifanayo. Kodwa endaweni eyodwa amazinyo amabili akwanele. Futhi ngesikhathi lapho leli phasi liphambi kwensimu yesigaba, i-piston e-cylinder yokuqala itholakala phansi noma ephezulu, isikhungo esifile. Futhi ngalesi sikhathi, isignali ithunyelwa ku-unit control unit, equkethe i-algorithm ethile. Ngenxa yalokhu, i-microcontroller iyaqonda ukuthi i-piston ye-cylinder yokuqala ingenye yezikhundla eziphambili.

Funda isignali

Isignali yi-pulse yamanje eqondwa yiyunithi yokulawula. Kodwa-ke, i-ECU ithatha izinkulumo ezimbili: kungakhathaliseki ukuthi kukhona noma cha. Kungenxa yokuthuthukiswa kwe-pulse kwi-VAZ-2114 sensor camshaft futhi efakwe. I-microcontroller isebenzisa ukushayela futhi iwuqhathanise nayo yonke idatha etholakala kwamanye amadivaysi afanayo. Khona-ke kukhona ukwakhiwa kohlobo lwezithombe ze-tatu-dimensional, ezifakwe ekhadini lephethiloli. Uma kungenakwenzeka, izinguquko zenzelwe ukuphazamiseka okuhlukahlukene noma ukuphazamiseka kwemigomo.

Yiqiniso, igrafu yakhiwe kuphela ngaphakathi kwesilawuli, futhi ungabona ngeso lengqondo kuphela uma uxhuma iyunithi yokulawula kumshini wokuxilonga. Ukulungiswa kwenzeka njalo, ngenkathi injini isebenza. Kumele kuqashelwe ukuthi ama-carburetor motors awazange afakwe amadivayisi anjalo. Kwezimoto zokuqala i-VAZ-2114 isisenjini se-camshaft asifakiwe, kanye nabasunguli bayo - i-VAZ-2109.

Indlela yokunquma ukuwohloka kwe-DF?

Kodwa uqonda kanjani ukuthi inzwa ye-camshaft ihlulekile? Amaphutha, i-VAZ-2114 ehlangene, ehlotshaniswa nabafundi, banezimpawu ezifanayo kakhulu. Lapho injini ingazinzile, iqala "i-troyte", futhi ikhompiyutha ebhodini ibonisa ukusetshenziswa kwe-petroli eyanda. Lezi zimpawu zihambelana nokuhlukana okuningi. Ukukhuluma ngokuqondile mayelana nenzwa yesigaba, kufanele uthole ikhodi yephutha: 0340 noma 0343. Amanani abonisa ukuthi inzwa yesikhala se-camshaft ayiphutha noma ivulekile esifundeni sayo.

Injini yokulawula injini ayitholi isignali evela ku-DF. Ngakho-ke, isikhathi sokushisa asilungiswa . Uhlelo lwe injini lushintshwa. Iyunithi yokulawula iqala ukusebenza kwenye, "ikhadi eliphuthumayo" lephethiloli. Akubandakanyi izimpawu zenye noma enye inzwa. Ngokufanayo, i-unit control unit nayo iziphatha lapho i-lambda probe (i-oxygen sensor) ihluleka .

Ukuhlolwa okubukwayo

Njengomthetho, ezimweni eziningi, ukuhlolwa okubonakalayo kweVAZ-2114 imoto ngokwanele. Inzwa ye-camshaft ingabuye ihlolwe. Abashayeli abaningi ababheki ngaphansi kwe-hood, ngokuvamile bayaphula izintambo, babhubhise umzimba wedivaysi, njll. Ngaphambi kokuqala ukulungiswa, qiniseka ukuthi ukwehluleka kuyingozi futhi kuyadingeka kuphela. Lo msebenzi wenziwa ngezigaba eziningana:

1. Okokuqala, hlola inzwa yesigaba. Bheka umonakalo owenziwe ngomshini kuwo. Uma kukhona ukuphahlazeka, ama-chips, ngokushesha ushintshe idivayisi.
2. Hlola oxhumana nabo abenza uxhumano. Uma kunesibindi noma umswakama kubo, susa. Hlola ukusebenza. Ngokuvamile imbangela yokungasebenzi embi ukungabikho kokuxhumana noma umswakama kuma-plugs. Okufanayo kuya kwe-oxidation.
3. Hlola i-wiring yama-breaks nama-shorts.

Ukufaka esikhundleni: izikhathi ezijwayelekile

Ngeshwa, ukuhlolwa okubukwayo akukwazi ukunikeza impendulo eqondile embuzweni wokuthi kungani inzwa yesigaba engasebenzi. Ngenxa yalesi sizathu, kubalulekile ukuxuba injini ukuze ufike kudivayisi bese uqhuba ukuhlolwa kwayo (nokufaka esikhundleni). Zonke izinhlobo zezimoto zinezenzo ezivamile. Kodwa kanjani ukuhlola inzwa ye-camshaft (i-VAZ-2114)? Nakhu okudingeka ukwenze:

• Susa ukuphela okungalungile kusuka ebhetri. Lokhu kuzoqinisekisa ukuphepha ngesikhathi somsebenzi.
• Lungiselela ithuluzi: izinkinobho, ama-screwdrivers, amakhanda kanye ne-ratchet.

Yilokho, ungaqala ukulungisa.

Ukushintshwa ngezimoto ezingu-8-valve

Inqubo ibonakala kanje:

1. Thola indawo yedivayisi: phezulu kwesithuthuthu, ngakwesokudla kwendawo yokuhlunga emoyeni.
2. Inzwa ye-camshaft ihlelwe nge-bolt eyodwa. Yizula ngokukhiye ngo-10.
3. Khipha i-DF.
4. Emgodini ngaphansi kwenzwa, faka indwangu ehlanzekile ukuvimbela uthuli nokungcola ukungena.
5. Yenza ukuhlola okubukwayo kwedivayisi.
6. Uma kukhona ukungcola okuningi emkhathini, susa. Zama ukuyihlola emsebenzini ngokuyibeka endaweni. Uma kungakusizi, uzodinga ukufaka esikhundleni senzwa.
7. Ngisho noma ukufakwa kwedivaysi entsha kungasebenzi, futhi iphutha lisekhona, isizathu siseqiniso lokuthi igijimi liguquliwe ku-camshaft. Futhi sidinga ingxenye entsha efanayo, hhayi inzwa ye-camshaft (VAZ-2114). Ngendlela, intengo yayo ingama-ruble angu-300.
8. Uma iphutha livela ngemva kokuphambana (ukuphumula) kwebhande lesikhathi, ngakho-ke, cishe ngesikhathi sokufakwa, kuhanjiswe kumazinyo amaningana. Hlanganisa icala lesikhathi bese uhlola amalebula.

I-sensor yesigaba ku-16-valve motor

Inqubo yonke iyafana ngokujwayelekile, kodwa kukhona futhi umehluko:

• Kutholakale emotweni ye-VAZ-2114 yesigaba senzwa ngaphansi komgwaqo, eduze ne-camshaft yokuqala.
• Susa i-radiator grille.
• Sula ama-DF amabili eqinisa izinsimbi ngokusebenzisa ikhanda elingu-10-mm kanye nesici sokwelulwa.
• Qinisekisa ukuthi othintana nabo bahlanzekile futhi bangonakali.
• Uma kukhona amaphutha, faka idivayisi entsha.
• Ungasebenzisi i-sealant noma i-gaskets. Indawo yokufaka imvelo enonya kakhulu. Kukhona izinguquko zokushisa njalo.

Kulokhu ukulungiswa sekuphelile. Ngemuva kokufaka inzwa entsha, injini iqala ukusebenza kumodi ekahle, ukusetshenziswa kwephethiloli kubuyela ezingeni elidlule, ukuthunjwa kanye ne "trochanie" kuyanyamalala. Kufanelekile ukunaka iqiniso lokuthi ama-valve ayisishiyagalombili alula kakhulu ukufaka esikhundleni - asikho isidingo sokuqeda igridi. Ngemuva kokuqedela ukulungiswa, qiniseka ukuthi uhlola ukusebenza kwe injini ngosizo lwezinkinobho zokuxilonga.
