Kugwira ntchito pagalimoto
Ntchito yayikulu ya sensor yagonjetso ndikuwona kugogoda pagogo ya injini, ndikuletsa kugogoda posintha nyumbayo, kuti muteteze injini kuti asawonongeke.
Sensor yogogoda imatembenuza kugwedeza kwamakina kukhala magetsi kukhala magetsi omwe amapatsira gawo lamagetsi ku gawo la magetsi (ecu). Ecu imasintha mbali yolowera molingana ndi chikwangwani kuti mupewe kuchitika kosalekeza. Sensor Syser nthawi zambiri imagwiritsa ntchito ukadaulo wa piezoelectic. Injiniyo ikagwedezeka ndikusiyidwa ndikupanga chizindikiro chamagetsi, omwe amafalikira kwa ecu kudzera mu waya wokhazikika pokonza.
Mfundo yogwira ntchito ya kugogoda imakhazikika pa piezoelecric zotsatira, injini zikagogoda, piezoelectric staramics mkati mwa sensor imazimitsidwa, kupanga chizindikiro chamagetsi. Zizindikiro izi zimatumizidwa ku ecu, yomwe imasinthiratu mbali yotsogola yotengera deta yosungidwa kuti mupewe kugogoda. Kuphatikiza apo, zomveketsa zimatha kudziwa kuthamanga ndi udindo wa injini, kupereka zambiri zothandizira kukonza injini.
Senso ya kugontha nthawi zambiri imakhazikitsidwa pamalo enaake mu injini ya injini, monga pakati pa ma cylinders a 2 ndi 3 a makina a cylinder kapena 2 ndi 2 clillinder. Malo ake okwera amachititsa kuti chidwi cha girsic i injini ndi kugogoda.
Ngati sensor yalephera, ngakhale siyingapangitse injiniyo kulephera kuyamba, idzayambitsa matenda monga yitter, kutaya mphamvu, mafuta osokoneza bongo. Chifukwa chake, ntchito yoyenera ya senso ya kugontha ndiyofunikira kwambiri injini.
Sensor Autoty Syyr ndi chipangizo chokhazikitsidwa pa injini ya injini, makamaka imagwiritsidwa ntchito kuwona kugogoda kwa injini. Pali mitundu yambiri ya masensa agogo, omwe amapezeka kwambiri ndi gawo la magnostictric komanso piezzoelectric.
Lembani ndi kapangidwe ka khungu
Magnenogrict: Muli ndi maginito pachimake, maginito okhazikika ndi coil yosakhazikika. Injiniya ikagwedezeka, maginito amphamvu, zomwe zimapangitsa kuti musinthe magnetic flux mu coil, zomwe zimapangitsa kuti zisungunuke.
Piezoelectric ceramic: injini ikagwedeza, nthawi mkati mwake imagwera kuti ipange chizindikiro chamagetsi. Chifukwa chizindikirocho ndi chofooka, cholumikizira nthawi zambiri chimakutidwa ndi waya wokhazikika.
Piezoelectric resonance: Yokhazikitsidwa kumtunda kwa thupi la injini, kugwiritsa ntchito piezoelecric zotsatira kuti asinthe makina kugwedezeka m'magetsi. Pamene pafupipafupi kugwedezeka pafupipafupi ndi kosagwirizana ndi chilengedwe cha sensor, reminomenb
Momwe Hight amagwira ntchito
Sensor yogogoda imazindikira kugwedezeka ndi mawu a injini ndikuwatembenuza kukhala zamagetsi omwe amatumizidwa ku bungwe loyang'anira injini (Ecu). Ecu imasintha mbali yolowera molingana ndi chizindikiro chovomerezeka kuti chichitike. Mfundo yofunika kwambiri yomwe ili motere:
Magnetrict.
Piezoelectric ceramic: injini ikagwedezeka, gawo la piezoelect lafinyidwa kuti lipange chizindikiro chamagetsi, Ecu imasintha nthawi yoyatsidwa malinga ndi chizindikiro.
Piezoelectric resonance mtundu wa kugwedezeka kwa Pinokock ndizofanana ndi chilengedwe cha sensor, zonena za remomenon zimachitika, ndipo magetsi akuluakulu agogodawa amatulutsa ku ecu.
Udindo wa zoponya zoseweretsa m'magalimoto
Ntchito yayikulu ya sensor yogogoda ndiyo kuyeza kuchuluka kwa injini. Injini ya injini ikayamba kugogoda, chizindikiro chamagetsi limafalikira kwa ecu, ndipo ecu imasintha mbali yofikiramo moyenera kuti ilepheretse kugogoda kwina. Kugogoda kungayambitse kuwonongeka kwa injini, kotero kuti masensa agogoda amagwira ntchito yofunika kwambiri poteteza injini.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga nkhani zina patsamba lino!
Chonde ndiyitane ngati mukufuna zinthu ngati izi.
