Iyini isondo lesignali ye-automobile crankshaft
Isondo lesignali ye-automobile crankshaft, eyaziwa nangokuthi i-crankshaft position sensor noma inzwa yesivinini senjini, umsebenzi wayo oyinhloko ukuqapha isivinini se-crankshaft kanye ne-Angle yenjini, ukuze kutholakale ngokunembile indawo ye-crankshaft. Idatha eqoqiwe idluliselwa ku-Engine Control Unit (ECU) noma kwamanye amasistimu ekhompiyutha afanelekile ukuze kuqinisekiswe ukulawulwa okunembile kwesikhathi sokuvutha kwenjini .
Isimiso sokusebenza
Isondo lesignali ye-crankshaft ngokuvamile liklanywa njengesondo elinamasegimenti amazinyo amaningi. Lapho isondo lesiginali lidlula inzwa, i-voltage ye-AC iyakhiqizwa, futhi imvamisa yale voltage iyashintshashintsha ngokushintsha kwesivinini. Lo mklamo uvumela inzwa ukuthi ilinganise isivinini senjini sisebenzisa isignali yokushaya kwenhliziyo.
Uhlobo nendawo yokufaka
Isondo lesignali ye-Crankshaft ngokomgomo wokukhiqiza amasignali lingahlukaniswa ngohlobo lokungeniswa kazibuthe, uhlobo lwe-photoelectric kanye nohlobo lweHholo izinhlobo ezintathu. Izinzwa zeHholo Ezivamile ngokuvamile zisebenzisa idizayini enezintambo ezi-3, okuhlanganisa ikhebula lamandla, ikhebula lesignali ye-AC kanye nekhebula elivikela isignali ye-AC. Indawo yokufaka ivamise ukuba kumsabalalisi, endaweni yendlu ye-clutch, ngaphambili noma ngemuva kwe-crankshaft, njll., kuye ngohlobo lwenzwa nomklamo wenjini .
Sebenza ngekhonsathi nezinye izingxenye
Isondo lesignali ye-crankshaft ngokuvamile lisebenza ngokuhlanganyela nenzwa yendawo ye-camshaft ukuze kunqunywe isikhathi esiyisisekelo sokubasa. Ngokuhlinzeka ngolwazi olunembayo lwendawo, baqinisekisa ukuthi injini ingasebenza ngokulandela ukudubula okunqunywe kusengaphambili, ngaleyo ndlela izuze ukusebenza kahle nangempumelelo.
Umsebenzi oyinhloko wesondo lesiginali ye-crankshaft yemoto ukuthola isivinini se-crankshaft kanye ne-Engeli yenjini, ukunquma indawo ye-crankshaft, bese udlulisela imiphumela etholiwe kuyunithi yokulawula injini (ECU) noma kwezinye izinhlelo zekhompuyutha ezifanele ukuqinisekisa ukulawulwa okunembile kwesikhathi sokuvutha kwenjini.
Ngokukhethekile, isondo lesignali ye-crankshaft (eyaziwa nangokuthi inzwa yokuma kwe-crankshaft noma inzwa yesivinini senjini) inemisebenzi elandelayo:
Hlola isivinini senjini : Thola isimo sokusebenza senjini ngokuthola isivinini se-crankshaft.
Thola indawo ye-TDC yepiston : Khomba indawo ye-TDC yesilinda piston ngayinye. Lokhu kubalulekile ekulawuleni ukuvutha kanye nesikhathi sokujova uphethiloli. Isibonelo, iyakwazi ukuhlinzeka ngamasiginali we-TDC yesilinda sokulawula ukuvutha kanye namasiginali we-TDC yesilinda sokuqala sokulawula umjovo kaphethiloli olandelanayo .
inikeza isignali ye-Crankshaft Angle : Ngokuthola i-engeli ye-crankshaft, qinisekisa ukuthi ukuthungela kwenjini kanye nesikhathi sokujova uphethiloli sinembile.
Isebenza ne-camshaft position sensor : Ivamise ukusebenza nenzwa yokuma ye-camshaft ukuze kuqinisekiswe ukuthi isikhathi esiyisisekelo sokuthungela senjini sinembile. Inzwa yokuma kwe-camshaft inquma ukuthi iyiphi i-cylinder piston eku-compression stroke, kuyilapho inzwa yendawo ye-crankshaft inquma ukuthi iyiphi i-cylinder piston eku-TDC .
Ngaphezu kwalokho, izici zokuklama zesondo lesignali ye-crankshaft zihlanganisa isondo elinamasegimenti amazinyo amaningi. Lapho isondo lesiginali lidlula inzwa, i-voltage ye-AC iyakhiqizwa okuvama kwayo kuguquguquka ngesivinini .
