Maitiro ekutarisa yekumhanyisa sensor

kana ICE inogara isina basa, saka, kazhinji, iwe uchafanirwa kutarisa akati wandei masensa (DMRV, DPDZ, IAC, DPKV) kuti uone ane mhosva. Pakutanga takatarisa nzira dzekuongorora:

• crankshaft position sensor;
• throttle position sensor;
• idle sensor;
• mass air flow sensor.

Ikozvino kuita-iwe-iwe pachako yekumhanyisa sensor cheki ichawedzerwa kune iyi runyorwa.

Muchiitiko chekuputsika, sensor iyi inotumira data isina kururama, iyo inotungamirira kusashanda kwete kwete chete injini inopisa mukati, asiwo zvimwe zvikamu zvemotokari. Iyo mota yekumhanyisa mita (DSA) inotumira masaini kune sensor iyo inodzora kushanda kweinjini pakusaita basa, uye zvakare, uchishandisa PPX, inodzora kuyerera kwemhepo iyo inodarika iyo throttle. Iyo yakakwirira kumhanya kwemotokari, kunowedzera kuwanda kwemasaini aya.

Nheyo yekushanda kweiyo kasi sensor

Iyo yekumhanyisa sensor mudziyo wemota zhinji dzemazuva ano yakavakirwa paHoro maitiro. Mukuita kwekushanda kwayo, inotumirwa kukombiyuta yemotokari ine pulse-frequency zviratidzo munguva pfupi. kureva, kwekiromita imwe yenzira, sensor inotumira anenge 6000 masaini. Muchiitiko ichi, kuwanda kwekutenderera kwepulse kunoenderana zvakananga nekumhanya kwekufamba. Iyo yemagetsi control unit inoverengera kumhanya kwemotokari zvichienderana nehuwandu hwezviratidzo. Pane chirongwa cheizvi.

The Hall effect chiitiko chemuviri chinosanganisira kutaridzika kwemagetsi emagetsi panguva yekuwedzera kwe conductor ine yakananga ikozvino mune magnetic field.

ndiyo yekumhanyisa sensor iri padivi pegiya bhokisi, kureva, mune yekumhanyisa dhiraivha mashini. Iyo chaiyo nzvimbo yakasiyana kune dzakasiyana mhando dzemota.

Maitiro ekuona kana iyo yekumhanyisa sensor isiri kushanda

Unofanira pakarepo kuteerera vakadaro zviratidzo zvekuputsika se:

• hapana kugadzikana kusina basa;
• iyo speedometer haishande zvakanaka kana kuti haishande zvachose;
• kuwedzera mafuta
• kuderedzwa kweinjini.

zvakare, iyo-bhodhi komputa inogona kupa kukanganisa pamusoro pekushaikwa kwezviratidzo paDSA. Sezvingatarisirwa, kana BC yakaiswa pamotokari.

Speed ​​sensor

Nzvimbo yeiyo sensor yekumhanyisa

Kazhinji kazhinji, kuparara kunokonzerwa nedunhu rakazaruka, saka, kutanga kune zvose, zvakakosha kuongorora kuvimbika kwayo. Kutanga iwe unofanirwa kubvisa simba uye kuongorora mabatirwo e oxidation uye tsvina. Kana zvirizvo, saka unofanirwa kuchenesa vanobatika uye kushandisa Litol.

Kazhinji waya dzinodambuka pedyo neplug, nekuti ndiko kwavanokotama uye chivharo chinogona kuputika. iwe unodawo kutarisa kushorwa munharaunda yevhu, iyo inofanira kuva 1 ohm. Kana dambudziko risati ragadziriswa, saka zvakakodzera kutarisa kasi sensor yekushanda. Zvino mubvunzo unomuka: sei kutarisa kasi sensor?

Pamotokari dzeVAZ, uye kune vamwe zvakare, sensor inowanzoiswa iyo inoshanda maererano neHoro effect (kazhinji inopa 6 pulses mune imwe shanduko yakazara). Asi pane zvakare sensors yeimwe musimboti: tsanga uye inductive... Ngatitangei titarise kusimbiswa kweiyo inonyanya kufarirwa DSA - zvichibva pane iyo Hall maitiro. Iyo sensor yakashongedzerwa nemapini matatu: pasi, voltage uye pulse chiratidzo.

Kuongorora iyo yekumhanyisa sensor

Kutanga iwe unofanirwa kuziva kana paine pasi uye voltage ye12 V mune vanobatika. Aya maitirwo anoridzwa uye pulse yekubata inoedzwa torsion.

Iyo voltage pakati peiyo terminal uye pasi inofanirwa kunge iri pakati pe0,5 V kusvika 10 V.

Nzira 1 (tarisa ne voltmeter)

1. Isu tinobvisa iyo yekumhanyisa sensor.
2. Isu tinoshandisa voltmeter. Isu tinoona kuti ndeipi terminal ine chekuita nei. Isu tinobatanidza iyo inopinda yekusangana yevoltmeter kune iyo terminal inoburitsa pulse masaini. Kubatana kwechipiri kwevoltmeter yakavakirwa painjini yekupisa mukati kana mutumbi wemotokari.
3. Kutenderedza iyo yekumhanyisa sensor, isu tinoona pane zviratidzo here mubasa rekutenderera uye kuyera iyo inobuda voltage ye sensor. Kuti uite izvi, iwe unogona kuisa chidimbu chechubhu pane axis ye sensor (tendeuka nekumhanya kwe 3-5 km / h.) Iyo inokurumidza kutenderedza sensor, iyo yakakwira voltage uye frequency mu voltmeter. kuva.

Nzira 2 (pasina kubvisa kubva mumotokari)

1. Isu tinoisa mota pane rolling jack (kana yenguva dzose telescopic imwe) kuitira kuti chimwe chinhu vhiri rimwe harina kubata pamusoro nyika.
2. Isu tinobatanidza ma sensor contacts ne voltmeter.
3. Isu tinotenderedza vhiri uye kuona kana voltage ichioneka - kana paine voltage uye frequency muHz, ipapo yekumhanyisa sensor inoshanda.

Nzira 3 (tarisa nekutonga kana girobhu rechiedza)

1. Bvisa iyo impulse waya kubva kune sensor.
2. Tichishandisa kudzora, tiri kutsvaga "+" uye "-" (kare kubatidza ignition).
3. Isu tinorembera vhiri rimwe senge mune yakapfuura nzira.
4. Isu tinobatanidza kutonga kune "Signal" waya uye kutenderera gumbo nemaoko edu. Kana "-" ichivhenekera pane control panel, ipapo sensor yekumhanyisa iri kushanda.

Kana kutonga kusiri pedyo, saka unogona kushandisa waya ine girobhu. Cheki inoitwa sezvinotevera: tinobatanidza rumwe rutivi rwetambo kune kuwedzera kwebheteri. Imwe chiratidzo kune chinongedzo. Pakutenderera, kana sensor iri kushanda, mwenje unopenya.

Dhizaini yekubatanidza

DS tarisa nemuongorori

Kutarisa iyo yekumhanyisa sensor drive

1. Isu tinosimudza mota pajeki kuitira kuti titurike chero vhiri rekumberi.
2. Tiri kutsvaga sensor drive inonamira kunze kwebhokisi neminwe yedu.
3. Tenderedza vhiri netsoka.

Speed ​​sensor yekutyaira

Kuongorora iyo DC drive

Tinonzwa neminwe yedu kana dhiraivha iri kushanda uye kuti inoshanda zvakadzikama. Kana zvisina kudaro, saka tinoparadzanisa dhiraivha uye kazhinji tinowana mazino akakuvadzwa pamagiya.

Reed chinja DS bvunzo

Iyo sensor inogadzira masaini emhando yerectangular pulses. Kutenderera kuri 40-60% uye switching kubva 0 kusvika 5 volts kana kubva 0 kusvika bhatiri voltage.

Induction DS bvunzo

Chiratidzo chinobva pakutenderera kwemavhiri, chokwadi, chinofanana nekushanduka kwemafungu emhepo. Naizvozvo, voltage inosiyana nekumhanya kwekutenderera. Zvese zvinoitika nenzira imwechete sepaiyo crankshaft angle sensor.
