Iyini inzwa ye-camshaft yezimoto
Inzwa ye-camshaft yezimoto (eyaziwa nangokuthi inzwa yesignali ehambisanayo) iyithuluzi elisetshenziselwa ukuthola indawo kanye ne-engela ye-camshaft, enikeza isignali eyinhloko yokulawula ukushaqeka ku-ECU ukuqinisekisa ukusebenza kahle nokuzinzile kwenjini.
Umsebenzi oyinhloko
I-Youdaoplaceholder0 Nquma ukuhlukaniswa kwesilinda kanye nokuma : Ngokuthola indawo yesikhathi sangempela se-camshaft, kusiza i-ECU ukuhlonza ngokunembile isikhungo esiphezulu esifile sokucindezelwa kwepiston yesilinda sokuqala, kufinyelela ekulawulweni kokujova uphethiloli okulandelanayo, ukulungiswa kwesikhathi sokushiswa kanye nokulawulwa kokuqhumisa.
Ukufakwa kwesignali ye-Youdaoplaceholder0 ku-ECU: Guqula i-engeli enamandla ye-camshaft ibe ukufakwa kwesignali kagesi ku-ECU, okusebenza njengesisekelo esiyinhloko sokulawula ukushisa kanye nokufakwa kukaphethiloli.
Indawo yokufaka
Ngokuvamile ifakwa engxenyeni engaphambili yesembozo se-camshaft (njengengxenye engaphambili ye-camshaft yokungenisa enguNombolo 1 yenjini yeToyota K3-VE), futhi kwamanye amamodeli, ifakwa ngaphakathi kwephampu kawoyela enomfutho ophezulu noma umsabalalisi.
Uhlobo kanye nomgomo wokusebenza
Isebenzisa isakhiwo sikagesi-magnetic. Ngokubona izinguquko kumandla kagesi abangelwa izinguquko zikagesi lapho i-CAM ijikeleza, iyiguqula ibe yisignali yesikhundla. Isibonelo, inzwa ye-magneto-electric enamaphini amathathu yenjini ye-Toyota K3-VE ikhipha amasignali okushaya ngephini yesikhathi (emele ama-angle angu-60°, 180°, kanye no-360° crank).
Izimpawu eziyinhloko zenzwa ye-camshaft enephutha emotweni zifaka phakathi ubunzima bokuqala, isivinini esingazinzile sokungenzi lutho, ukusetshenziswa kukaphethiloli okwandisiwe, izibani zamaphutha ezikhanyisiwe, ukusheshisa okubuthakathaka kanye nokuthuthumela komzimba. Lezi zimpawu zivela ekungakwazini kwenzwa ukudlulisa ngokunembile izimpawu zesikhundla se-camshaft ku-ECU, okuholela ekuphazamisekeni kwezinhlelo zokuthungela kanye nokujova uphethiloli.
Izimpawu eziyinhloko ze- ziyi-
Ubunzima bokubamba indawo0 ekuqaliseni noma ukungakwazi ukuqala : Uchungechunge lokusha luyaphazamiseka, injini kunzima ukuyiqala, futhi ingase ime ngokuzumayo lapho ifudumala.
I-Youdaoplaceholder0 Isivinini sokungenzi lutho esingazinzile kanye nokuzamazama komzimba wemoto : I-ECU ithola izimpawu eziphazamisayo, okuholela ekushintsheni okukhulu kwesivinini sokungenzi lutho kanye nokuzamazama kwemoto okungavamile.
I-Youdaoplaceholder0 Ukwanda okukhulu kokusetshenziswa kukaphethiloli : Uhlelo lokufaka uphethiloli lusebenza ngokungahlelekile, okuholela ekushisweni kukaphethiloli okungaphelele kanye nokwanda kokusetshenziswa kukaphethiloli.
I-Youdaoplaceholder0 Ukusheshisa okubuthakathaka kanye nokushayela ngokuxhamazela : I-ECU yehluleka ukulawula ngokunembile ukufakwa kukaphethiloli kanye nokushisa, okuholela ekukhishweni kwamandla okuthambile kanye nokusheshisa okuhamba kancane noma okuxhamazela.
Isibani sephutha sihlala sivuliwe: uhlelo lwe-OBD luthola okungajwayelekile bese luqala isibani sephutha senjini (njengekhodi yephutha ye-P0340-P0344).
I-Youdaoplaceholder0 Ukuguguleka kwenjini okusheshayo : Ukungasebenzi kahle kwesikhathi eside kungaholela ekushiseni okungaphelele futhi kuqinise ukuguguleka kwenjini kwangaphakathi.
Umthelela ongaba khona we-Youdaoplaceholder0
Amaphutha angabangela ukonakala kokukhishwa kwegesi, ukulinganiselwa kwamandla (imodi yokuxhuga), noma ukuma ngesikhathi sokushayela. Kudingeka ukulungiswa ngesikhathi ukuze kuvinjelwe ukulimala kwenjini.
Inzwa ye-camshaft yezimoto idinga ukuhlanzwa okuqondiwe ngokusekelwe ezimweni zokusetshenziswa. Uma kukhona ukwehla kwamandla, ukusetshenziswa kukaphethiloli okungajwayelekile noma amakhodi amaphutha, ukuhlanza kungabuyisela ngempumelelo ukusebenza kwenzwa. Uma kungekho ukuphazamiseka, ukuhlanza njalo akudingeki.
Ukunqunywa kwe-Youdaoplaceholder0 ngesidingo sokuhlanza
I-Youdaoplaceholder0 kumele ihlanzwe :
Injini ibhekane nezimo ezingavamile njengobunzima bokuqalisa, ukuphazamiseka kwamandla, kanye nokwenyuka okukhulu kokusetshenziswa kukaphethiloli (isibonelo, endabeni ye-BMW, ukusetshenziswa kukaphethiloli kwehle kusuka ku-12.8L kuya ku-8.2L/100km).
I-ECU ithola amakhodi amaphutha ahlobene nenzwa yesikhundla se-camshaft (njenge-P0340/P0341).
Udaka lwamafutha noma izingcezu zensimbi ezinamathela ebusweni benzwa (uma ubukhulu budlula u-0.3mm, zidinga ukwelashwa).
Izimo ze-Youdaoplaceholder0 lapho kungadingeki ukuhlanzwa:
Inzwa igoqwe esikrinini sesihlungi esihlanganisiwe futhi ihlanzwa njalo ngowoyela wenjini (njengoba iklanyelwe kwamanye amamodeli ezimoto).
Ngaphansi kokulungiswa okuvamile, injini isebenza kahle ngaphandle kwamakhodi ephutha.
Umhlahlandlela wokusebenza kokuhlanza ochwepheshe we-Youdaoplaceholder0
Amaphuzu ayisihluthulelo e-Youdaoplaceholder0 okuqaqa nokuhlanganisa :
Sebenzisa isikhongozeli esingu-10mm bese usijikelezisa ngo-30° emuva ukuze uvuleke. Sinyakazise kancane ukuze uvimbele izingxenye zikagesi ukuthi zingawi.
Nqamula i-terminal engalungile yebhethri ukuze uvimbele i-short circuit.
Imininingwane yokuhlanza ye-Youdaoplaceholder0 :
Futha isihlanzi se-carburetor nge-engela engu-45°, ugxile ekuhlanzeni izikhala ze-rotor (hhayi ngaphezu kwemizuzu emi-2).
Uma unamabala aqinile, sebenzisa ibhulashi elithambile elihlanganiswe nesihlanzi se-elekthronikhi ukuze ukhuhle kancane.
Imigomo yokwamukelwa kwe-Youdaoplaceholder0 :
Umjikelezo womsebenzi wamagagasi asikwele atholwe yi-oscilloscope kufanele ube phakathi kuka-45% no-55%.
Ngemva kokufakwa kabusha, ikhodi yephutha idinga ukusulwa futhi isitifiketi sokuhlola isekethe sixhunywe.
Izincomo zomjikelezo wokulungisa we-Youdaoplaceholder0:
Ukuhlanza kokuvimbela kwe-Youdaoplaceholder0 :
Hlola ngokuvumelana njalo emakhilomitha angu-60,000 noma uma ibhande lesikhathi lishintshwa.
Izimoto ebezisebenzisa uwoyela wenjini osezingeni eliphansi isikhathi eside kufanele zihlolwe kafushane zibe amakhilomitha angu-30,000.
Ukulungiswa kwansuku zonke kwe-Youdaoplaceholder0 :
Hlola ukuthi ipulaki yesensa iyavuza yini uwoyela njalo uma ushintsha uwoyela wenjini.
Gcina indawo yenjini ihlanzekile futhi ugweme ukufuthwa ngqo kwezibhamu zamanzi ezinomfutho ophezulu endaweni yesensa.
Uma ufuna ukwazi okwengeziwe, qhubeka ufunda ezinye izihloko ezikulesi siza!
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
Inkampani Zhuo Meng Shanghai Auto Co., Ltd. uzibophezele ekuthengiseni i-MG&I-MAXUSizingxenye zezimoto zamukelekile ukuthenga.
