Yini eyenziwa yi-crankshaft sensor emotweni
Indima yenzwa ye-crankshaft yemoto emotweni ifaka phakathi izici ezilandelayo:
Ukulawula Isikhathi Sokuvutha : Izinzwa zesikhundla se-crankshaft ziqapha indawo yokujikeleza kwe-crankshaft futhi zinikeze idatha ebalulekile kwi-Unit control Unit (ECU) ukusiza ekunqumeni isikhathi esifanele sokudubula sesilinda ngasinye. Lokhu kuqinisekisa ukuthi i-spark plug iyavutha lapho i-piston ifika ku-TDC futhi ingxube icindezelwa esimweni sayo esifanele, ngaleyo ndlela kufezwe ukushiswa kukaphethiloli okusebenza kahle kakhulu futhi kuthuthukiswe amandla enjini kanye nokonga.
Ukulawulwa kokujova uphethiloli: Inzwa yesikhundla se-crankshaft isetshenziswa futhi ukulawula uhlelo lokujova uphethiloli, ukuqinisekisa ukuthi uphethiloli ukhishwa ngesikhathi esifanele ukuze kuhlangatshezwane nezidingo zenjini. Ngokuqapha indawo ye-crankshaft, uhlelo lungalawula ngokunembile inani lokujova uphethiloli ukuqinisekisa imiphumela emihle kakhulu yokusha ngaphansi kwezimo zokusebenza ezahlukene.
Ukuqala nokusebenza kwenjini: Ngesikhathi sokuqalisa injini, inzwa yesikhundla se-crankshaft iqinisekisa ukuthi injini iqala ngesikhathi esifanele futhi igcina ukusebenza okuzinzile. Ngaphezu kwalokho, ihilelekile ekulawulweni kwesivinini sokungasebenzisi lutho kanye nokulawula ukuhwamuka kukaphethiloli, okusiza i-ECU ukulungisa ukuvulwa kwe-throttle noma indawo ye-actuator yokungasebenzisi lutho ukuze kugcinwe isivinini senjini sokungasebenzisi lutho esizinzile.
Uma inzwa yesikhundla se-crankshaft ihluleka, uhlelo lokulawula lwe-elekthronikhi lwemoto lungabona futhi lubonise inkinga ngokufunda ikhodi yephutha, okwenza kube lula ukuxilongwa nokulungiswa kwamaphutha ngochwepheshe.
Inzwa yesikhundla se-crankshaft isebenza ukuhlinzeka ngedatha ebalulekile ohlelweni lokuphathwa kwenjini ngokulinganisa ngokunembile nokubika isikhundla nesivinini se-crankshaft. Ithola futhi ikhiphe izimpawu ze-stop point, izimpawu ze-crankshaft Angle, kanye nezimpawu zesivinini senjini, ezifakwa kwi-ECU ngesikhathi sangempela, lapho i-ECU ibala khona isikhathi sokudubula esifanele kanye nevolumu yokufaka uphethiloli yesilinda ngayinye.
Izinzwa ze-crankshaft zezimoto (i-CPS noma i-CKP) zidlala indima ebalulekile ezimotweni. Zingenye yezinzwa ezibaluleke kakhulu ohlelweni lokulawula injini, futhi imisebenzi yazo eyinhloko ifaka:
Isivinini senjini: Inzwa ye-crankshaft ingaqapha isivinini sokujikeleza kwe-crankshaft ngesikhathi sangempela, ukuze ibale ngokunembile isivinini senjini. Lolu lwazi lubaluleke kakhulu ekunqumeni izinga lokujova uphethiloli kanye ne-Angle yokushisa ethuthukisiwe.
Nquma indawo yepiston : Ngokuzwa i-engeli yokujikeleza ye-crankshaft, inzwa ye-crankshaft inganquma indawo ethile yepiston kusilinda. Lokhu kubalulekile ukulawula isikhathi sokuvutha kanye nokufakwa kukaphethiloli .
Ukuqapha isimo sokusebenza kwenjini: ingaqapha isimo sokusebenza kwenjini, uma itholakale njengomlilo noma ukuntuleka komlilo kanye nezinye izinkinga, izobamba ngokushesha isignali engavamile, futhi ifike ngesikhathi eyunithi yokulawula injini ukuze ithumele ulwazi lwesixwayiso.
Lungiselela ukusebenza kahle kokukhishwa kwegesi: Ngokulawula okunembile kwendawo ye-crankshaft, inqubo yokushiswa kwegesi ingathuthukiswa, ukukhishwa kwezinto eziyingozi kungancishiswa, kanye nokusebenza kahle kokukhishwa kwegesi emotweni.
Eminye imisebenzi: Ngaphezu kokulawula ukujova uphethiloli kanye nokusha, inzwa ye-crankshaft ibamba iqhaza ekulawuleni isivinini esingasebenzi, ekulawuleni ukujikeleza kabusha kwegesi yokukhipha, kanye nasekulawuleni ukuhwamuka kukaphethiloli.
Uhlobo nendawo yokufaka
Kunezinhlobo ezimbili eziyinhloko zezinzwa ze-crankshaft: uhlobo lwe-magnetic pulse kanye nohlobo lwe-Hall. Izinzwa ze-magnetic pulse zivame ukufakwa eduze kwe-transmission housing ye-flywheel, kuyilapho izinzwa ze-Hall zifakwa eceleni kwe-crankshaft pulley ekugcineni kwe-crankshaft noma e-transmission housing eduze kwe-flywheel. Indawo eqondile yokufaka izohluka kuye ngemodeli kanye nomklamo.
