Umsebenzi wesondo lesignali ye-crankshaft.
Indima eyinhloko yesondo lesignali le-crankshaft ukunquma ngokunembile indawo kanye ne-engela ye-crankshaft, kanye nesivinini senjini. Ngokuvamile isebenza ngokubambisana nezinzwa zesikhundla se-camshaft ukuqinisekisa ukusebenza okuzinzile kwenjini nokuthuthukisa ukusebenza. Ukucacisa:
Nquma indawo ye-crankshaft: Isondo lesignali ye-crankshaft, ngomklamo walo kanye nendawo yalo ethile, livumela inzwa ukuthi ibone ngokunembile indawo yamanje kanye ne-Engela ye-crankshaft, okubaluleke kakhulu ekulawuleni isikhathi sokusha kanye nokufakwa kukaphethiloli.
Ukusebenza ngenzwa yesikhundla se-camshaft: Isondo lesignali le-crankshaft lisebenza nenzwa yesikhundla se-camshaft ukunquma isikhathi esiyisisekelo sokusha. Lokhu kubambisana kuqinisekisa ukuthi injini ingashayiswa ngesikhathi esifanele ukuze isebenze kahle futhi ishelele.
Isondo lesignali ye-crankshaft ngokuvamile lisetshenziswa isondo lesignali yamazinyo angu-60-2, kukhona ingxenye yezinyo engekho, yi-sensor ngokwesimo sezinyo kanye nesignali yezinga eliphezulu neliphansi lengxenye yezinyo engekho ukwahlulela isigaba 1 se-crankshaft. Lo mklamo uvumela i-sensor ukuthi yahlulele ngokunembile indawo kanye nesigaba se-crankshaft ngesimo sezinyo kanye nezibonakaliso zezinga eliphezulu neliphansi zezinyo elingekho, futhi ngaleyo ndlela ifinyelele ukulawula okunembile kwesimo sokusebenza kwenjini. umklamo okhethekile wesondo lesignali ye-crankshaft, kuhlanganiswe nokucutshungulwa kwesignali ye-crankshaft yi-ECU (iyunithi yokulawula ye-elekthronikhi), ungomunye wobuchwepheshe obubalulekile bokuqaphela ukusebenza kahle nokuzinzile kwenjini.
Ukuqapha isivinini senjini: Isondo lesignali le-crankshaft liphinde liqaphe isivinini senjini futhi lidlulisele idatha ku-ECU (iyunithi yokulawula kagesi) ukuze kulawulwe isikhathi sokusha kanye nesikhathi sokujova, okubalulekile ekuthuthukiseni ukusebenza kahle kukaphethiloli kanye nokunciphisa ukukhishwa kwegesi.
Ngamafuphi, isondo lesignali le-crankshaft liyingxenye ebalulekile ezinjinini zesimanje, lisiza izinhlelo zokulawula injini ukuthi zisebenze kahle futhi ziqinisekise ukusebenza okuphephile ngokunikeza ulwazi olunembile lwesikhundla kanye nesivinini.
Yiziphi izimpawu zokwehluleka kwediski yesiginali ye-crankshaft?
Uma idiski yesignali ye-crankshaft ihluleka, izoba nemiphumela eminingi ekusebenzeni okuvamile kwemoto, ikakhulukazi kanje:
Okokuqala, isibonakaliso sephutha siyakhanya, okuyimpendulo eqondile yesistimu yokuzihlola yemoto ngemva kokuthola inkinga. Okwesibili, lapho uqala imoto, ungathola ukuthi inqubo yokuqala inde kunokujwayelekile, ngoba injini izama ukuqala ngokujwayelekile ngenzwa yesikhundla se-camshaft, kodwa ngenxa yephutha lediski yesiginali, inqubo yokuqala iyaphazamiseka. Ngesikhathi sokushayela, umsebenzi wokuhamba ngesikebhe ofanayo wemoto ungathinteka futhi ungakwazi ukusebenza ngokujwayelekile. Ngaphezu kwalokho, injini ingase ibonakale idlidliza ngokungajwayelekile, futhi ikhiphe ngisho nentuthu emhlophe.
Umsebenzi oyinhloko wenzwa yesikhundla se-crankshaft ukuqapha isivinini senjini, futhi ngokusho kwalolu lwazi kunqunywe inani lokufakwa kukaphethiloli kanye ne-Angle yokushisa ethuthukisiwe. Lokhu kuqinisekisa ukuthi injini iyadubula futhi iqalwe ngesikhathi esifanele, ngaleyo ndlela kuncishiswe umonakalo emotweni. Kodwa-ke, uma kunenkinga ngephaneli yesignali ye-crankshaft, lolu chungechunge lwemisebenzi yokuqapha nokulungisa lungathinteka, okuholela ekusebenzeni kwenjini okungazinzile.
Inzwa yesikhundla se-crankshaft ivame ukufakwa ku-distributor, okuyingxenye ebalulekile yokuthola indawo ye-TDC ye-piston, ngakho-ke ngezinye izikhathi ibizwa ngokuthi inzwa ye-TDC. Uma le sensor yehluleka, kufanele ihlolwe futhi ilungiswe ngokushesha ukuze kuvinjelwe ukwehluleka ukuthi kwande futhi kubangele umonakalo omkhulu emotweni.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
