Umsebenzi wesondo lesiginali ye-Crankshaft.
Umsebenzi oyinhloko wesondo lesignali ye-crankshaft ukucacisa kahle indawo kanye ne-Angle ye-crankshaft, kanye nesivinini senjini. Ivamise ukusebenza ngokubambisana nezinzwa ze-camshaft ukuze kuqinisekiswe ukusebenza kwenjini okuzinzile nokwandisa ukusebenza kahle. Ukucacisa:
Nquma indawo ye-crankshaft: Isondo lesignali ye-crankshaft, ngomklamo walo othize nendawo, ivumela inzwa ukuthi ibone ngokunembile indawo yamanje kanye ne-Engeli ye-crankshaft, okubalulekile ekulawuleni isikhathi sokubasa kanye nomjovo kaphethiloli.
Isebenza nge-camshaft position sensor: Isondo lesignali ye-crankshaft lisebenza nenzwa yokuma ye-camshaft ukuze linqume isikhathi esiyisisekelo sokubasa. Lokhu kusebenzisana kuqinisekisa ukuthi injini ingadunyiswa ngesikhathi esifanele ukuze isebenze kahle futhi isebenze kahle.
Isondo lesignali ye-crankshaft ngokuvamile lisetshenziswa isondo lesignali yamazinyo angu-60-2, kukhona ingxenye yezinyo engekho, ngenzwa ngokuya ngesimo sezinyo kanye nesignali yezinga eliphezulu neliphansi lengxenye yezinyo elahlekile ukuze kwahlulele isigaba sokuqala se-crankshaft. Lo mklamo uvumela inzwa ukuthi ihlulele ngokunembile indawo kanye nesigaba se-crankshaft ngokusebenzisa ukuma kwezinyo kanye namasignali ezinga eliphezulu neliphansi lezinyo elingekho, futhi ngaleyo ndlela izuze ukulawula okunembile kwesimo sokusebenza kwenjini. idizayini ekhethekile yesondo lesignali ye-crankshaft, ehlanganiswe nokucutshungulwa kwesignali ye-crankshaft yi-ECU (iyunithi yokulawula ngogesi), ingobunye bobuchwepheshe obubalulekile bokubona ukusebenza kahle nokuzinzile kwenjini. .
Isivinini senjini yokuqapha: Isondo lesignali ye-crankshaft liphinde liqaphe isivinini senjini futhi lidlulisele idatha ku-ECU (iyunithi yokulawula i-elekthronikhi) ukuze ilawulwe ngokunembile isikhathi sokubasa kanye nesikhathi sokujova, okubalulekile ekuthuthukiseni ukusebenza kahle kukaphethiloli kanye nokunciphisa ukungcola.
Ngamafuphi, isondo lesignali ye-crankshaft liyingxenye ebalulekile ezinjinini zesimanje, esiza amasistimu okulawula injini enze kahle ukusebenza nokuqinisekisa ukusebenza okuphephile ngokunikeza indawo enembile nolwazi lwejubane.
Yiziphi ukubonakaliswa kokuhluleka kwediski yesiginali ye-crankshaft?
Uma idiski yesiginali ye-crankshaft ihluleka, izoba nochungechunge lwemiphumela ekusebenzeni okujwayelekile kwemoto, ikakhulukazi ngale ndlela elandelayo:
Okokuqala, inkomba yephutha iyakhanyisa, okuyimpendulo eqondile yohlelo lokuzihlola lwemoto ngemva kokuthola inkinga. Okwesibili, lapho uqala imoto, ungathola ukuthi inqubo yokuqala yinde kunokujwayelekile, ngoba injini izama ukuqala ngokujwayelekile ngokusebenzisa inzwa yendawo ye-camshaft, kodwa ngenxa yephutha lediski yesignali, inqubo yokuqala ivinjelwe. Ngesikhathi sokushayela, ukusebenza kwe-uniform cruise cruise yemoto kungase kuthinteke futhi awukwazi ukusebenza ngendlela evamile. Ngaphezu kwalokho, injini ingase ibonakale idlidliza engavamile, futhi ikhiphe intuthu emhlophe.
Umsebenzi oyinhloko wenzwa yendawo ye-crankshaft ukuqapha isivinini senjini, futhi ngokwalolu lwazi ukunquma inani lomjovo kaphethiloli kanye ne-Angle yokuthungela kusengaphambili. Lokhu kuqinisekisa ukuthi injini iyashiswa futhi iqalwe ngesikhathi esifanele, ngaleyo ndlela kunciphisa umonakalo emotweni. Kodwa-ke, uma kunenkinga ngephaneli yesignali ye-crankshaft, lolu chungechunge lwemisebenzi yokuqapha nokulungiswa lungathinteka, okuholela ekusebenzeni kwenjini okungazinzile.
Inzwa yokuma kwe-crankshaft ivamise ukufakwa kumsabalalisi, okuyingxenye ebalulekile yokuthola indawo ye-TDC yepiston, ngakho-ke kwesinye isikhathi ibizwa ngokuthi inzwa ye-TDC. Uma le nzwa ihluleka, kufanele ihlolwe futhi ilungiswe ngokushesha ukuze kuvinjelwe ukwehluleka ekwandeni futhi kubangele umonakalo omkhulu emotweni.
