Za crankshaft sensor VAZ 2107

Kugwira ntchito kwa injini ya jakisoni mwachindunji kumadalira gawo ngati crankshaft sensor. Imathandizira kuwonetsetsa kuti ma injectors amalumikizana ndi makina oyatsira, chifukwa chake dzina lake lina ndi sensor yanthawi yoyatsira. Pa VAZ 2107, jekeseni crankshaft sensa akhoza kulephera pakapita nthawi.

Crankshaft sensa pa Vaz 2107 - kapangidwe ndi mfundo ntchito

The crankshaft udindo sensa kapena DPKV pa VAZ 2107 zimatsimikizira ntchito injini (osati khola, koma wonse). Ndi izo, ECU ikudziwa malo omwe crankshaft ili. Kuchokera apa, gawo lolamulira limadziwa malo a pistoni m'masilinda, omwe amakhudza mwachindunji jekeseni wa mafuta kudzera mu jekeseni ndi zochitika za spark kuti ziwotchere msonkhano wa mafuta.

Chipangizo chomwe chikufunsidwacho chili ndi mapangidwe osavuta. Masensa omwe amaikidwa mu zisanu ndi ziwiri zonse amagwira ntchito pa mfundo ya inductance. Gawoli limapangidwa ndi chitsulo cha cylindrical, pamwamba pomwe waya (coil) amavulala. Pamwamba pa koyiloyo ndi yokutidwa ndi maginito okhazikika. Kugwiritsiridwa ntchito kwa chipangizocho kumagwirizanitsidwa ndi giya la mphete, lomwe limamangiriridwa ku crankshaft. Ndi chithandizo cha mphete iyi yomwe sensa imajambula zizindikiro ndikuzitumiza ku kompyuta. Mfundo yogwiritsira ntchito chipangizochi ndi motere: pamene dzino la korona lili pamtunda wa chitsulo cha DPKV, mphamvu ya electromotive imapangitsidwa pozungulira. Magetsi amawoneka kumapeto kwa mafunde, omwe amakhazikitsidwa ndi ECU.

The sprocket ali ndi mano 58. Mano awiri achotsedwa pa gudumu, zomwe zimafunika kudziwa malo oyamba a crankshaft. Ngati DPKV alephera, amene ndi osowa kwambiri, ndiye kuyamba injini ndi kuthamanga n'zosatheka. Mtundu wa sensor, womwe umayikidwa pa VAZ 2107, uli ndi mawonekedwe awa: 2112-3847010-03/04.

Zizindikiro za sensa yosweka

Chizindikiro chachikulu cha kuwonongeka kwa DPKV ndikulephera kuyambitsa injini. Kulephera koteroko kumachitika chifukwa cha kulephera kwathunthu kwa chipangizocho. Ngati pamwamba pa DPKV zaipitsidwa kapena kukhudzana ndi oxidized, zovuta zotsatirazi zikhoza kuzindikirika:

1. Kuwonongeka kwa kayendetsedwe ka magalimoto: kuthamanga kofooka, kutaya mphamvu, kugwedezeka pamene mukusuntha magiya.
2. Kutembenuka kumayamba kuyandama, osati kokha pakuchita, komanso poyendetsa.
3. Wonjezerani kugwiritsa ntchito mafuta. Ngati ECU ilandira chizindikiro chosokoneza, izi zimakhudza kwambiri ntchito ya injectors.
4. Kuwonekera kwa kugogoda mu injini.

Ngati zizindikiro zili pamwambazi zapezeka, ndiye kuti DPKV iyenera kuyang'aniridwa. Kuti muchite izi, muyenera kudziwa komwe sensor ya crankshaft ili. Pa Vaz 2107 DPKV ili pachivundikiro kutsogolo kwa injini, kumene wokwera bulaketi. Pamitundu ina yamagalimoto, chinthu ichi chikhoza kukhala tsidya lina la crankshaft pafupi ndi flywheel. Ngati mukuganiza kuti DPKV yasokonekera, muyenera kuyang'ana.

Njira zowunika DPKV

Mutha kuyang'ana kukwanira kwa sensa ya crankshaft pa asanu ndi awiri onse m'njira zitatu zosiyanasiyana. Poyamba, ziyenera kudziwidwa nthawi yomweyo kuti kusagwira ntchito kwa chipangizocho kungadziwike mowonekera. Kuti muchite izi, yang'anani gawolo, ndipo pamaso pa kuipitsidwa, komanso ma microcracks mu nyumba ya maginito, munthu akhoza kuweruza kulephera kwake. Kuipitsa kumachotsedwa mosavuta, koma pamaso pa microcracks, gawolo liyenera kusinthidwa.

Sensa ya crankshaft pa jekeseni ya VAZ 2107 imafufuzidwa m'njira zitatu:

1. Kuyang'ana kukana. Gwiritsani ntchito multimeter seti kuti muyesere kukana. Ma probe amakhudza ma terminals a chipangizocho. Ngati chipangizocho chikuwonetsa mtengo kuchokera ku 550 mpaka 750 Ohms, ndiye kuti chinthucho ndi choyenera kugwiritsidwa ntchito. Ngati mtengowo ndi wapamwamba kapena wotsika kuposa wanthawi zonse, ndiye kuti gawolo liyenera kusinthidwa.
2. Kuwona inductance. Lumikizani ma LED kapena ma multimeter amatsogolera ku ma terminals a chipangizocho. Nthawi yomweyo, ikani chipangizocho kumayendedwe a DC voltage kuyeza. Bweretsani chinthu chachitsulo kumapeto kwa chidutswacho ndikuchichotsa mwamsanga. Pankhaniyi, kuwonjezeka kwa magetsi kuyenera kuchitika (LED idzawunikira). Izi zikuwonetsa kuti DPKV ikugwira ntchito.
3. Oscilloscope kufufuza. Njira yolondola komanso yodalirika yoyesera ndi oscilloscope. Kuti tichite zimenezi, DPKV chikugwirizana ndi chipangizo, ndiyeno chitsulo gawo ayenera kubweretsa kwa izo. Dera limatsimikizira magwiridwe antchito olondola a DPKV.

The inductive crankshaft position sensor yomwe imagwiritsidwa ntchito pa zisanu ndi ziwirizo imapanga ma sinusoidal pulses. Amalowa pakompyuta, pomwe amasinthidwa kukhala ma rectangular pulse. Kutengera ndi ma pulse awa, gawo lowongolera limasankha kugwiritsa ntchito kugunda kwa ma injectors ndi ma spark plugs panthawi yoyenera. Ngati pakuyesa zidapezeka kuti DPKV ndi yolakwika, iyenera kusinthidwa.

Momwe mungasinthire sensor ya crankshaft pa zisanu ndi ziwiri

Kudziwa kumene DPKV ili pa VAZ 2107, disassembly chipangizo sikudzakhala kovuta. Njirayi sizovuta ndipo sizitenga nthawi yambiri. Malangizo mwatsatanetsatane momwe mungasinthire sensor ya crankshaft pa VAZ 2107 ikuwoneka motere:

1. Ntchito ikuchitika pansi pa nyumba ya galimoto, koma zikhoza kuchitika pansi.
2. Lumikizani chingwe tayi ku DPKV.
3. Pogwiritsa ntchito screwdriver ya Phillips, masulani clip yomwe imateteza sensor.
4. Chotsani chipangizocho ndikuyika chatsopano m'malo mwake. Assembly ikuchitika motsatira dongosolo la disassembly.

Pambuyo m'malo chipangizo, mukhoza kuona ntchito ya injini. Ngakhale gawolo sililephera kawirikawiri, tikulimbikitsidwa kuti nthawi zonse mukhale ndi sensor yopuma mu makina. Chinthu chikalephera, chimatha kusinthidwa mwachangu kuti chiziyenda.

Chifukwa chake, ziyenera kukumbukiridwa kuti DPKV ndiye sensor yofunika kwambiri. Ili ndi mapangidwe osavuta ndipo salephera kawirikawiri. Mtengo wa chipangizocho kwa onse asanu ndi awiri ndi pafupifupi ma ruble 1000. Ndibwino kuti muyang'ane gawolo osati pazizindikiro zoyambirira za kusagwira ntchito, komanso nthawi ndi nthawi kuyeretsa malo ogwirira ntchito kuti asaipitsidwe.
