The chipangizo ndi mfundo ntchito ya sensa kugogoda
Resonant Knock Sensor Chipangizo
Pali mitundu iwiri ya masensa ogogoda - resonant ndi Broadband. Ma resonant pakali pano amaonedwa kuti ndi osatha (amatchedwa "akale") ndipo sagwiritsidwa ntchito m'magalimoto atsopano. Amakhala ndi kukhudzana kumodzi ndipo amapangidwa ngati mbiya. Sensa ya resonant imasinthidwa pafupipafupi ndi mawu ena, omwe amafanana ndi ma microexplosions mu injini yoyaka mkati (mafuta detonation). Komabe, pa injini iliyonse yoyaka mkati, ma frequency awa ndi osiyana, chifukwa zimatengera kapangidwe kake, m'mimba mwake pisitoni, ndi zina zotero.
Mbali inayi, sensor yogogoda ya Broadband imapereka chidziwitso chokhudza mawu ku injini yoyaka mkati kuchokera ku 6 Hz mpaka 15 kHz (pafupifupi, ikhoza kukhala yosiyana ndi masensa osiyanasiyana). Mwakutero, ECU imasankha kale ngati phokoso linalake ndi microexplosion kapena ayi. Sensa yotereyi imakhala ndi zotuluka ziwiri ndipo nthawi zambiri imayikidwa pamagalimoto amakono.
Mitundu iwiri ya masensa
Maziko a mapangidwe a Broadband knock sensor ndi chinthu cha piezoelectric, chomwe chimasintha makina omwe amapangidwa kuti akhale magetsi ndi magawo ena (nthawi zambiri, kusintha kwamagetsi komwe kumaperekedwa ku gawo lamagetsi lamagetsi a injini yoyaka mkati, ECU ndi kawirikawiri werengani). chotchedwa weighting agent chimaphatikizidwanso mu kapangidwe ka sensa, zomwe ndizofunikira kuwonjezera mphamvu yamakina.
Sensa ya Broadband ili ndi zolumikizira ziwiri, zomwe, kwenikweni, voteji yoyezera imaperekedwa kuchokera ku chinthu cha piezoelectric. Mtengo wamagetsiwa umaperekedwa ku kompyuta ndipo, kutengerapo, gawo lowongolera limasankha ngati kuphulika kumachitika panthawiyi kapena ayi. Pazifukwa zina, vuto la sensa likhoza kuchitika, lomwe ECU imadziwitsa dalaivala poyambitsa nyali yochenjeza ya Check Engine pa dashboard. Pali njira ziwiri zofunika zowonera sensa yogogoda, ndipo izi zitha kuchitika ndikuchotsa komanso osachotsa sensor pamalo ake oyika pa injini.
Kuyeza kwa magetsi
Ndizothandiza kwambiri kuyang'ana ICE kugogoda sensa ndi multimeter (dzina lina ndiloyesa magetsi, likhoza kukhala lamagetsi kapena makina). Chekechi chitha kuchitika pochotsa sensa pampando kapena kuyang'ana pomwepo, komabe, zidzakhala zosavuta kugwira ntchito ndikuchotsa. Chifukwa chake, kuti muwone, muyenera kuyika multimeter mumayendedwe amagetsi olunjika (DC) pafupifupi 200 mV (kapena kuchepera). Pambuyo pake, gwirizanitsani zofufuza za chipangizocho kumalo opangira magetsi a sensa. Yesetsani kuyanjana bwino, monga khalidwe la mayeso lidzadalira izi, chifukwa ma multimeters otsika (otsika mtengo) sangazindikire kusintha pang'ono kwa magetsi!
ndiye muyenera kutenga screwdriver (kapena chinthu china cholimba cha cylindrical) ndikuchiyika mu dzenje lapakati la sensa, ndiyeno muzichitapo kanthu kuti pakhale mphamvu mu mphete yachitsulo yamkati (musapitirire, nyumba ya sensor ndi pulasitiki ndipo imatha kusweka!). Pankhaniyi, muyenera kulabadira kuwerengera kwa multimeter. Popanda kuchitapo kanthu pamakina pa sensa yogogoda, mtengo wamagetsi kuchokera pamenepo udzakhala zero. Ndipo mphamvu yogwiritsidwa ntchito kwa izo ikuwonjezeka, mphamvu yotulutsa mphamvu idzawonjezekanso. Kwa masensa osiyanasiyana, amatha kukhala osiyana, koma nthawi zambiri mtengo umachokera ku zero mpaka 20 ... 30 mV ndi kuyesetsa kochepa kapena kwapakatikati.
Njira yofananira ikhoza kuchitidwa popanda kugwetsa sensa pampando wake. Kuti muchite izi, muyenera kuletsa kulumikizana kwake (chip) ndikulumikizanso ma probes a multimeter kwa iwo (komanso kupereka kukhudzana kwapamwamba). ndiye, mothandizidwa ndi chinthu chilichonse, kanikizireni kapena kugogoda ndi chinthu chachitsulo pafupi ndi malo omwe aikidwa. Pankhaniyi, mtengo wamagetsi pa multimeter uyenera kuwonjezeka pamene mphamvu yogwiritsidwa ntchito ikuwonjezeka.

Komabe, ndikofunikira kupanga cheke chowonjezera.
Komanso, mtengo wamagetsi otulutsa kuchokera ku sensa yogogoda ukhoza kuyang'aniridwa ndikuyika pazitsulo zina (kapena zina, koma kuti ziziyendetsa bwino mafunde, ndiye kuti, kuphulika) ndikuzigunda ndi chinthu china chachitsulo mkati. kuyandikira pafupi ndi sensa (samalani kuti musawononge chipangizocho!). Sensa yogwira ntchito iyenera kuyankha izi mwa kusintha mphamvu yamagetsi, yomwe idzawonetsedwa mwachindunji pazenera la multimeter.
Mofananamo, mukhoza kuyang'ana resonant ("wakale") kugogoda sensa. Kawirikawiri, ndondomekoyi ndi yofanana, muyenera kugwirizanitsa kafukufuku wina ndi kukhudzana kwake, ndipo yachiwiri ndi thupi lake ("nthaka"). Pambuyo pake, muyenera kugunda thupi la sensa ndi wrench kapena chinthu china cholemera. Ngati chipangizocho chikugwira ntchito, ndiye kuti mtengo wamagetsi otulutsa pawindo la multimeter udzasintha kwakanthawi kochepa. Apo ayi, mwinamwake, sensor ili kunja kwa dongosolo. Komabe, ndikofunikira kuyang'ananso kukana kwake, popeza kutsika kwamagetsi kungakhale kochepa kwambiri, ndipo ma multimeter ena sangagwire.
Pali masensa omwe ali ndi zolumikizira (zotulutsa zotulutsa). Kuyang'ana iwo ikuchitika chimodzimodzi, chifukwa ichi muyenera kuyeza mtengo wa linanena bungwe voteji pakati pa kukhudzana ake awiri. Kutengera kapangidwe ka injini yoyatsira mkati, sensa iyenera kuthetsedwa chifukwa cha izi kapena ikhoza kuwonedwa pomwepo.
Chonde dziwani kuti pambuyo pakukhudzidwa, mphamvu yowonjezereka yotulutsa iyenera kubwereranso pamtengo wake woyambirira. Masensa ena ogogoda olakwika, akayambika (kugunda kapena pafupi nawo), amachulukitsa mtengo wamagetsi otulutsa, koma vuto ndilakuti atakumana nawo, voteji imakhalabe yayikulu. Kuopsa kwa izi ndikuti ECU sichizindikira kuti sensayo ndi yolakwika ndipo siyiyambitsa kuwala kwa Injini. Koma zenizeni, malinga ndi chidziwitso chochokera ku sensa, gawo lowongolera limasintha mbali yoyatsira ndipo injini yoyaka mkati imatha kugwira ntchito mwanjira yomwe siili yabwino kwagalimoto, ndiye kuti, kuyatsa mochedwa. Izi zitha kuwonekera pakuwonjezeka kwamafuta, kuwonongeka kwa magwiridwe antchito, zovuta pakuyambitsa injini yoyaka mkati (makamaka nyengo yozizira) ndi zovuta zina zazing'ono. Kuwonongeka kotereku kungayambitsidwe ndi zifukwa zosiyanasiyana, ndipo nthawi zina zimakhala zovuta kumvetsa kuti zimayambitsidwa ndi ntchito yolakwika ya sensor yogogoda.
Kukana muyeso
Kugogoda masensa, onse resonant ndi burodibandi, akhoza kufufuzidwa ndi kuyeza kusintha kukana mkati mu mode zamphamvu, ndiko kuti, mu ntchito yawo. Njira yoyezera ndi mikhalidwe ikufanana kwathunthu ndi muyeso wamagetsi womwe tafotokozazi.
Kusiyana kokha ndiko kuti multimeter imasinthidwa osati muyeso yoyezera voteji, koma muyeso yoyezera mtengo wamagetsi. Muyeso woyezera umafika pafupifupi 1000 ohms (1 kOhm). M'malo odekha (opanda detonation), kukana kwamagetsi kudzakhala pafupifupi 400 ... 500 Ohms (mtengo weniweniwo udzakhala wosiyana ndi masensa onse, ngakhale omwe ali ofanana ndi chitsanzo). Kuyeza kwa masensa a wideband kuyenera kuchitidwa polumikiza ma multimeter probes ku ma sensor lead. ndiye kugogoda pa sensa yokhayo kapena pafupi ndi izo (pamalo omwe amamangiriridwa mu injini yoyaka mkati, kapena, ngati itathyoledwa, ikani pamwamba pazitsulo ndikuyigunda). Nthawi yomweyo, yang'anani mosamala zowerengera za tester. Panthawi yogogoda, mtengo wotsutsa udzawonjezeka pang'ono ndikubwereranso. Kawirikawiri, kukana kumawonjezeka kufika 1 ... 2 kOhm.
