Momwe mungayang'anire sensa yothamanga

ngati ICE amagulitsa popanda ntchito, ndiye, mwina, muyenera kuyang'ana masensa angapo (DMRV, DPDZ, IAC, DPKV) kuti mudziwe wolakwa. M'mbuyomu tidawona njira zotsimikizira:

• crankshaft udindo sensa;
• throttle position sensor;
• sensa idling;
• misa ya air flow sensor.

Tsopano cheke cha sensor yothamanga muzichita nokha chidzawonjezedwa pamndandandawu.

Pakawonongeka, sensa iyi imatumiza deta yolakwika, yomwe imayambitsa kuwonongeka kwa injini yoyaka mkati, komanso zigawo zina za galimoto. The galimoto liwiro mita (DSA) amatumiza siginecha kuti sensa kuti amawongolera magwiridwe antchito a injini popanda ntchito, komanso, pogwiritsa ntchito PPX, imayang'anira kayendedwe ka mpweya kamene kamadutsa phokoso. Kuthamanga kwa galimoto kumakwera kwambiri, kumapangitsa kuti zizindikirozi zikhale zowonjezereka.

Mfundo ya ntchito ya liwiro sensa

Chida chojambulira liwiro cha magalimoto amakono ambiri chimachokera ku Hall effect. M'kati mwa ntchito yake, imatumizidwa ku kompyuta ya galimoto ndi zizindikiro za pulse-frequency panthawi yochepa. ndiye, kwa kilomita imodzi ya njira, sensa imatumiza ma siginali pafupifupi 6000. Pankhaniyi, kuchuluka kwa kufalikira kwamphamvu kumayenderana mwachindunji ndi liwiro la kuyenda. Chigawo choyang'anira pakompyuta chimangowerengera liwiro lagalimoto potengera kuchuluka kwa zizindikiro. Ili ndi pulogalamu ya izi.

The Hall effect ndizochitika zakuthupi zomwe zimakhala ndi maonekedwe a magetsi a magetsi panthawi ya kukula kwa kondakitala ndi mphamvu yeniyeni mu mphamvu ya maginito.

ndiye sensa yothamanga yomwe ili pafupi ndi bokosi la gear, ndiye kuti, mumakina oyendetsa liwiro. Malo enieni ndi osiyana ndi mitundu yosiyanasiyana ya magalimoto.

Momwe mungadziwire ngati sensa yothamanga sikugwira ntchito

Muyenera nthawi yomweyo kulabadira zimenezi zizindikiro za kusweka monga:

• palibe kukhazikika kwachabechabe;
• Speedometer sichigwira ntchito bwino kapena sichigwira ntchito konse;
• kuchuluka kwamafuta;
• kuchepetsa kuthamanga kwa injini.

Komanso, kompyuta pa bolodi akhoza kupereka cholakwika za kusowa kwa siginecha pa DSA. Mwachibadwa, ngati BC waikidwa pa galimoto.

Kuthamanga kwachangu

Malo othamangitsira liwiro

Nthawi zambiri, kuwonongeka kumachitika chifukwa cha dera lotseguka, chifukwa chake, choyamba, ndikofunikira kuzindikira kukhulupirika kwake. Choyamba muyenera kusagwirizana mphamvu ndi kuyendera kulankhula kwa makutidwe ndi okosijeni ndi dothi. Ngati ndi choncho, ndiye kuti muyenera kuyeretsa zolumikizira ndikuyika Litol.

Nthawi zambiri mawaya amathyoka pafupi ndi pulagi, chifukwa ndi pamene amapindika ndipo chitsekererocho chimatha. muyeneranso kuyang'ana kukana mu dera lapansi, lomwe liyenera kukhala 1 ohm. Ngati vuto silinathe, ndiye kuti ndi bwino kuyang'ana liwiro sensa kuti operability. Tsopano funso likubwera: momwe mungayang'anire sensor yothamanga?

Pa magalimoto a VAZ, ndi enanso, sensa nthawi zambiri imayikidwa yomwe imagwira ntchito molingana ndi Hall effect (nthawi zambiri imapereka ma pulses 6 mukusintha kumodzi). Koma palinso masensa a mfundo yosiyana: bango ndi inductive... Tiyeni tikambirane kaye kutsimikizira kwa DSA yotchuka kwambiri - kutengera zotsatira za Hall. Ndi sensa yokhala ndi zikhomo zitatu: pansi, magetsi ndi chizindikiro cha pulse.

Kuyang'ana liwiro la sensor

Choyamba muyenera kudziwa ngati pali grounding ndi voteji 12 V mu kulankhula. Zolumikizana izi zimayimbidwa ndipo kugunda kwa mtima kumayesedwa.

Mphamvu yamagetsi pakati pa terminal ndi pansi iyenera kukhala pakati pa 0,5 V mpaka 10 V.

Njira 1 (onani ndi voltmeter)

1. Timachotsa sensor yothamanga.
2. Timagwiritsa ntchito voltmeter. Timapeza kuti ndi terminal iti yomwe imayambitsa chiyani. Timalumikiza kulumikizana komwe kukubwera kwa voltmeter ku terminal yomwe imatulutsa ma pulse sign. Kulumikizana kwachiwiri kwa voltmeter kumakhazikitsidwa pa injini yoyaka mkati kapena thupi lagalimoto.
3. Kuzungulira sensor liwiro, timazindikira pali zizindikiro zilizonse pazantchito ndi kuyeza mphamvu yotulutsa sensor. Kuti muchite izi, mutha kuyika chidutswa cha chubu pa olamulira a sensa (kutembenuzirani liwiro la 3-5 km / h.) Mukasinthasintha kachipangizo kameneka, kukweza kwamagetsi ndi ma frequency mu voltmeter kuyenera. kukhala.

Njira 2 (popanda kuchotsa mgalimoto)

1. Timayika galimoto pa jack rolling (kapena telescopic imodzi) kuti chinachake gudumu limodzi silinakhudze pamwamba dziko.
2. Timalumikiza kukhudzana kwa sensa ndi voltmeter.
3. Timatembenuza gudumu ndikuzindikira ngati voteji ikuwoneka - ngati pali voteji ndi ma frequency mu Hz, ndiye kuti sensor yothamanga imagwira ntchito.

Njira 3 (onani ndi chowongolera kapena babu)

1. Lumikizani waya wothamanga kuchokera ku sensa.
2. Pogwiritsa ntchito kuwongolera, tikuyang'ana "+" ndi "-" (m'mbuyomu kuyatsa moto).
3. Timapachika gudumu limodzi monga momwe timachitira kale.
4. Timagwirizanitsa ulamuliro ku "Signal" waya ndikuzungulira gudumu ndi manja athu. Ngati "-" ikuwunikira pagawo lowongolera, ndiye kuti sensor yothamanga ikugwira ntchito.

Ngati kuwongolera sikuli pafupi, ndiye kuti mutha kugwiritsa ntchito waya wokhala ndi babu. Chekecho chikuchitika motere: timagwirizanitsa mbali imodzi ya waya ndi kuphatikiza kwa batri. Chizindikiro china ku cholumikizira. Pozungulira, ngati sensa ikugwira ntchito, kuwalako kumawoneka.

Chithunzi cholumikizira

DS fufuzani ndi woyesa

Kuyang'ana liwiro la sensor drive

1. Timakweza galimotoyo pa jack kuti tiyike gudumu lakutsogolo.
2. Tikuyang'ana sensa drive yomwe imatuluka m'bokosi ndi zala zathu.
3. Sinthani gudumu ndi phazi lanu.

Speed ​​sensor drive

Kuyang'ana pagalimoto ya DC

Timamva ndi zala zathu ngati galimotoyo ikugwira ntchito komanso ngati ikugwira ntchito mokhazikika. Ngati sichoncho, ndiye kuti timasokoneza galimotoyo ndipo nthawi zambiri timapeza mano owonongeka pamagiya.

Reed switch DS mayeso

Sensa imapanga zizindikiro zamtundu wamtundu wamakona amakona. Kuzungulira ndi 40-60% ndipo kusinthaku kumachokera ku 0 mpaka 5 volts kapena kuchokera ku 0 kupita kumagetsi a batri.

Induction DS mayeso

Chizindikiro chomwe chimachokera ku kuzungulira kwa magudumu, kwenikweni, chimafanana ndi kugwedezeka kwa mphamvu ya mafunde. Choncho, voteji amasintha malinga ndi liwiro rotational. Chilichonse chimachitika chimodzimodzi monga pa crankshaft angle sensor.
