Pressure sensor mugalimoto ya Audi 80

Chida chonga ngati sensa yamafuta amafuta ndi chipangizo chomwe cholinga chake chachikulu ndikusinthira ma sign amphamvu yamakina kukhala ma sign amtundu wamagetsi. Pankhaniyi, ma signature amatha kukhala ndi ma voltages amitundu yosiyanasiyana. Akasinthidwa, zizindikirozi zimalola kuti kukakamizidwa kuyerekezedwe. Lero tikambirana komwe kuli sensor yamphamvu pa Audi 80, momwe mungayang'anire, momwe mungayendetsere.

Chodziwika kwambiri ndi njira ziwiri zomwe zimagwira ntchito mosiyanasiyana: 0,3 bar sensor ndi 1,8 bar sensor. Njira yachiwiri ndi yosiyana chifukwa imakhala ndi chotchinga chapadera choyera. Ma injini a dizilo amagwiritsa ntchito mipiringidzo 0,9 yokhala ndi zotsekemera zotuwa.

Madalaivala ambiri ali ndi chidwi ndi komwe kupanikizika kwa sensor kuli pa Audi 80. Malo amadalira mtundu wa injini. Pa masilindala anayi onse, chipangizo cha bar 0,3 chili kumapeto kwa chipika cha silinda, kumanzere kwa chipinda cha injini. Ndi kuthamanga kwamafuta kwa 1,8 kapena 0,9, zidazo zimamangirizidwa bwino ndi phiri la fyuluta. Pa injini ya silinda isanu, zida zili kumanzere kwa silinda, moyang'anizana ndi dzenje lomwe likuwonetsa kuchuluka kwa mafuta omwe alipo.

Kodi sensor yamafuta ya Audi 80 imagwiritsidwa ntchito bwanji?

Pamene injini ikuyenda, mikangano nthawi zina imapangika mmenemo. Kumalo kumene mavuto oterowo apezeka, mafuta ayenera kuperekedwa. Angagwiritsidwe ntchito m'njira zosiyanasiyana, monga kupopera mbewu mankhwalawa. Chofunikira pakupopera mbewu mankhwalawa ndi kukhalapo kwamphamvu. Kupanikizika kumachepa, kuchuluka kwa mafuta omwe amaperekedwa kumachepa ndipo izi zimapangitsa kuti pampu yamafuta isagwire bwino ntchito. Chifukwa cha kusokonekera kwa mpope woperekera mafuta, kukangana kwa zinthu zofunika kumawonjezeka kwambiri, chifukwa cha magawo omwe amatha kupanikizana, ndipo kuvala kwa "mtima wamagalimoto" kumathamanga. Kupewa mbali zonse zoipa, mu Audi 80 b4 kondomu dongosolo, monga zitsanzo zina, mafuta mphamvu kachipangizo kamangidwe kamangidwe kuti azilamulira.

Chizindikiro cholowetsa chimawerengedwa m'njira zingapo. Kawirikawiri, dalaivala salandira lipoti latsatanetsatane, amangokhala ndi zizindikiro monga mawonekedwe a oiler pazitsulo kapena zida mu kanyumba ngati chizindikirocho chatsika pang'ono.

Pamitundu ina yamagalimoto, sensa imatha kuwonetsedwa pamlingo wa zida ndi mivi. M'mitundu yaposachedwa, kuchuluka kwa kuthamanga kwa block sikugwiritsidwa ntchito kwambiri pakuwongolera monga kuwongolera magwiridwe antchito a injini.

Chida cha zida

Pokonzekera chitsanzo chachikale, chomwe chakhala kale chodziwika bwino, Audi 80 b4 mafuta kuthamanga sensa, miyeso zimachokera ku kusintha kwa elasticity wa nembanemba. Pokhala pansi pa kusintha kwa mawonekedwe ndi zochitika zina, nembanembayo imakhala ndi mphamvu pa ndodo, yomwe imakanikiza madzi mu chitoliro. Kumbali ina, madziwo amakanikizira pa ndodo ina ndipo amakweza kale kutsinde. Komanso chipangizo choyezera ichi chimatchedwa dynamometer.

Zosankha zamakono zamakono zimapanga miyeso pogwiritsa ntchito sensa ya transducer. Sensa iyi imayikidwa pa block ndi ma silinda, ndipo zowerengera zimatumizidwa ku kompyuta yomwe ili pa bolodi ngati mawonekedwe amagetsi osinthidwa. Mu zitsanzo zaposachedwa, ntchito ya chinthu chodziwikiratu imakhala pa nembanemba yapadera, yomwe imakhala yotsutsa. Kukana kumeneku kungasinthe mlingo wa kukana panthawi ya deformation.

Kuyang'ana ma sensors amafuta

Ndondomekoyi ikuchitika m'magawo angapo:

1. Choyamba, muyenera kuyang'ana mlingo wa mafuta.
2. Mkhalidwe wa mawaya a masensa onsewo amawunikiridwa (onse pa 0,3 bar ndi 1,8 bar).
3. Pambuyo pake, sensor yokakamiza imachotsedwa ndi bar 0,3.
4. M'malo mwa sensa yowonongeka, manometer amtundu woyenera amaikidwa.
5. Ngati mukukonzekera kugwiritsa ntchito masensa owonjezera monga VW, sitepe yotsatira ndikupukuta sensayi mu test stand stand.
6. Pambuyo pake, kugwirizana kumapangidwa ku misa ya chipangizo kuti chiwongolere.
7. Kupitilira apo, chipangizo choyezera voteji chimalumikizidwa ndi sensor yokakamiza kudzera pa chingwe chowonjezera, ndipo mita yamagetsi imalumikizidwanso ndi batri, i.e. pamtengo.
8. Ngati chirichonse chikugwirizana bwino ndipo chikhoza kugwira ntchito bwino, diode kapena nyali idzayatsa.
9. Pambuyo poyatsa diode kapena nyali, ndikofunikira kuyambitsa injini ndikuwonjezera liwiro.
10. Ngati choyezera kuthamanga chikufika pa 0,15 mpaka 0,45 bar, nyali yowonetsera kapena diode imazima. Ngati izi sizichitika, muyenera kusintha sensor ndi bar 0,3.

Pambuyo pake, timayang'ana sensor ya 1,8 ndi 0,9 bar, zomwe zimachitika motere:

1. Timadula mawaya a sensor pressure yamafuta ndi 0,8 bar kapena 0,9 bar pa injini ya dizilo.
2. Pambuyo pake, timagwirizanitsa chipangizo choyezera kuti tiphunzire kuchuluka kwa mphamvu yamagetsi pamtengo wabwino wamtundu wa batri ndi sensor yokha.
3. Ngati zonse zachitika molondola, nyali yowongolera sayenera kuyatsa.
4. Pambuyo pake, kuti muwone sensor pa bar 0,9, onjezani liwiro la injini mpaka chipangizo choyezera chomwe chaperekedwa chikuwonetsa kuwerenga m'chigawo cha 0,75 bar mpaka 1,05 bar. Ngati tsopano nyali siziyatsa, muyenera kusintha sensa.
5. Kuti muwone sensor ndi 1,8, liwiro limachulukitsidwa mpaka 1,5-1,8 bar. Nyaliyo iyeneranso kuyatsa apa. Ngati izi sizichitika, ndiye kuti muyenera kusintha zida.

Ma sensor amphamvu amafuta mu Audi 80 ayenera kuyang'aniridwa pafupipafupi. Momwe mungachitire - onani pansipa.
