Oyenera Cummins pressure sensor injini magawo 3408589

1. mtundu

Pali mitundu yambiri yamasensa amakina, monga resistance strain gauge pressure sensor, semiconductor strain gauge pressure sensor, piezoresistive pressure sensor, inductive pressure sensor, capacitive pressure sensor, resonant pressure sensor and capacitive acceleration sensor. Koma chogwiritsidwa ntchito kwambiri ndi piezoresistive pressure sensor, yomwe ili ndi mtengo wotsika kwambiri, yolondola kwambiri komanso mikhalidwe yabwino yofananira.

2.udindo wofunikira

Ma sensor opanikizika samangogwiritsidwa ntchito kwambiri pakuyezera kupanga, komanso amawonedwa nthawi zambiri m'miyoyo yathu masiku ano. Magalimoto athu ambiri ali ndi masensa omwe ali ndi mphamvu. Mwina anthu ambiri akudziwa kuti pali zosemphana maganizo mu magalimoto, koma kwenikweni, palinso mphamvu masensa pa njinga zamoto wamba.

Mphamvu ya njinga yamoto imachokera ku kuyaka kwa mafuta mu silinda ya injini ya petulo. Kuyaka kokwanira kokha kungapereke mphamvu yabwino, ndipo kuyaka kwabwino kuyenera kukhala ndi zinthu zitatu: kusakaniza bwino, psinjika yonse ndi kuyatsa koyenera. Kaya dongosolo la EFI lingathe kulamulira bwino chiŵerengero cha mpweya wamafuta mkati mwazofunikira zimatsimikizira mphamvu, chuma ndi ndondomeko yotulutsa injini. Kuwongolera kwa chiŵerengero cha mpweya ndi mafuta a injini ya petulo kumazindikiridwa ndikusintha momwe mafuta amayendera ndi kuchuluka kwa mpweya, kotero kuti kuyeza kulondola kwa kayendedwe ka mpweya kumakhudza mwachindunji kulondola kwa chiŵerengero cha mpweya ndi mafuta.

3.mapangidwe amkati

Zimapangidwa ndi matrix, waya wachitsulo kapena zojambulazo, pepala lodzitchinjiriza ndi waya wotuluka. Malinga ndi ntchito zosiyanasiyana, kukana kwa mtengo wotsutsa kukana kungathe kupangidwa ndi wopanga, koma kuchuluka kwa mtengo wotsutsa kuyenera kutsatiridwa: mtengo wotsutsa ndi wochepa kwambiri, ndipo kuyendetsa komweko kumafunika kukulirakulira. Nthawi yomweyo, kutentha kwa strain gauge kumapangitsa kuti kutentha kwake kukhale kokwera kwambiri. Ikagwiritsidwa ntchito m'malo osiyanasiyana, kukana kwa strain gauge kumasintha kwambiri, kutulutsa zero kumawonekera, ndipo zero zosinthira zero ndizovuta kwambiri. Komabe, kukana ndikokulirapo, kutsekereza ndikokwera kwambiri, ndipo kutha kukana kusokonezedwa ndi ma elekitirodi akunja ndikosavuta. Nthawi zambiri, ndi pafupifupi ma euro makumi ambiri mpaka makumi masauzande a mayuro.
