Indima ye-Sensor ye-Camshaft isikhundla.
Iqhaza Lezinzwa Zesikhundla Sezithuthi Zesikhundla:
1, inzwa ye-camshaft isikhundla ukuqoqa isiginali ye-angle enamandla e-camshaft, futhi ifake iyunithi yokulawula ngogesi (ECU), ukuze inqume isikhathi sokulahla kanye nesikhathi sokuhlwitha, ngakho-ke ukuthathwa nokuphela kokudla nokuphelelwayo kuyatholakala;
2, ukuze kufezeke ngokulandelana kokulawulwa kokulimala kwamafutha okulawula, ukulawulwa kwesikhathi sokulahla kanye nokulawulwa kwe-deflagration. Ngaphezu kwalokho, isiginali yesikhundla saseCamshaft isetshenziselwa ukukhomba umzuzu wokuqala wokulahla lapho injini iqala. Ngoba inzwa yesikhundla se-camshaft ingakhomba ukuthi iyiphi i-cylinder piston esezofinyelela i-TDC, ibizwa ngokuthi inzwa yokuhlonza i-cylinder;
I-3, isakhiwo kanye nesimiso esisebenzayo se-camshaft isikhundla senzwa kanye ne-crankshaft isikhundla sesikhundla ngokufanayo, futhi kuvame ukufakwa ndawonye, kepha isikhundla sokufaka semodeli ngayinye sehlukile, kepha kufanele ifakwe esikhundleni sobudlelwano bokuhambisa obuqondile ne-crankshaft, i-camshaft, i-flywheel noma umsabalalisi;
4, mane nje usebenzise uhlelo lwe-crankshaft sensor ecu lunenqubo ekhethekile yokuhlukanisa ukulandelana, ukuhlukanisa ukulandelana kokulahla kwesilinda, iphuzu elidumile "ukubala", i-crankshaft isebenza ngenombolo enqunyelwe. Ngakho-ke uhlelo lungakwazi "ukubala" ama-cylinders ahlukile okudubula endaweni efanayo ye-crankshaft, ngakho-ke inzwa eyodwa yanele.
I-Camshaft Photomen Sensor yaziwa nangokuthi inzwa yokukhonjwa ye-Cylinder, ukuze ihlukanise kusuka ku-crankshaft isikhundla senzwa (CPS), inzwa ye-camshaft isikhundla ngokuvamile imelelwa yi-CIS. Umsebenzi we-Camshaft isikhundla se-Sensor ukuqoqa isibonakaliso sesikhundla se-valve camshaft futhi ufake i-ECU, ukuze i-ECU ingakhomba isikhungo esiphezulu se-cylinder Ngaphezu kwalokho, isiginali yesikhundla saseCamshaft isetshenziselwa ukukhomba umzuzu wokuqala wokulahla lapho injini iqala. Ngoba inzwa yesikhundla se-camshaft ingakhomba ukuthi iyiphi i-cylinder piston esezofinyelela i-TDC, ibizwa ngokuthi inzwa yokuhlonza i-cylinder.
I-Camshaft Sensor Ukusebenza Okubi
Ubunzima be-01 ekuqaliseni imoto
Ubunzima bokuqala imoto ukuvezwa okusobala kwephutha le-camshaft sensor. I-sensor yesikhundla se-camshaft inquma ukulandelana kwenjini. Lapho yehluleka, ukulandelana kokulahla kuyaphuma ngokuhleleka, okwenza injini iqale ngobunzima futhi kwesinye isikhathi ayiqali nhlobo. Lesi simo asisithinta kuphela ukusebenza kokuqala kwemoto, kepha futhi kungadala ukulimala okwengeziwe enjini. Ngakho-ke, uma nje kutholakala ukuthi imoto kunzima ukuqala, kufanele ubheke ukuthi ngabe inzwa ye-camshaft isebenza kahle ngokushesha okukhulu.
02 ukusheshisa ubuthakathaka
Ukwehluleka kwemoto ukusheshisa kuwukubonakaliswa okusobala komonakalo we-camshaft inzwa. Lapho inzwa ye-camshaft yehluleka, i-ECU ayikwazi ukubona ngokunembile ushintsho lwe-camshaft isikhundla. Lokhu kuzothinta izinhlelo zokudla nokuphelelwa yisikhathi zenjini, okuholele ekunciphiseni ekunciphiseni nasekuqedeni kohlelo lokuqeda amandla aseduzane. Ngoba lezi zinto ezibalulekile azisebenzi kahle, imoto izothola ukukhathala lapho isheshisa, ikakhulukazi lapho ijubane lingaphansi kwama-2500 rpm.
03 ukukhulisa uphethiloli
Ukusetshenziswa kaphethiloli okwandisiwe kungukubonakaliswa okusobala kokuhluleka kwenzwa ye-camshaft. Lapho inzwa ye-camshaft inephutha, uhlelo lwamafutha olusenziwa ngekhompyutha lungaba nesiphithiphithi, lubangele i-nozzle noma i-injector ukufiphala uphethiloli ngokuhleleka. Lesi simo somjovo esiphazamisekile asigcini nje ngokukhulisa ukusetshenziswa kwamafutha wemoto, kodwa futhi kungadala ukuthi ijubane le-Injini lingakwazi ukuthuthuka, futhi imoto ibonakala ibuthakathaka. Ngakho-ke, uma ukwanda okungajwayelekile kokusetshenziswa kwamafutha emoto kutholakala, kungahle kube yisiginali ukuthi inzwa ye-camshaft inephutha.
04 I-Veral Healt Light
Ukukhanya kwephutha lemoto kuvame ukusho ukuthi izinzwa eziningi zingasebenza ngokungasebenzi kahle. Ikakhulu lapho inzwa ye-camshaft yesikhundla ilimele, le nto isobala kakhulu. Izinzwa ze-Camshaft zivame ukuba nezinzwa ze-wire-wire ehholo, kufaka phakathi amakhebuli we-12V noma ama-5V wamandla, izintambo zesiginali kanye nezintambo ze-ling. Lapho ipulaki likhishwe futhi injini isiqalile, uma kungekho okukhishwayo kwamandla kagesi phakathi komugqa wesiginali nomugqa wesisekelo, lokhu kuvame ukusho ukuthi inzwa ilimele. Kulokhu, ukukhanya kwemoto ukwehluleka kwemoto kungenzeka ukukhumbuza umshayeli ukuthi ahlolwe okuningiliziwe.
05 Umzimba uthuthumela ngokungajwayelekile
Ukuzamazama komzimba okungajwayelekile kuwukubonakaliswa okusobala kokuhluleka kwenzwa ye-camshaft. Lapho kunenkinga nge-sensor ye-camshaft, i-enjini yokulawula injini yemoto kungenzeka ingakwazi ukufunda kahle isimo esisebenzayo senjini, okuholela ekusebenzeni kwenjini engazinzile nokuthuthumela komzimba okungajwayelekile. Le Jitter ivame ukubizwa ngokuthi imoto isheshisa noma icekela phansi. Ukuze kuqinisekiswe ukuphepha okushayela, lapho izinkinga ezinjalo zitholakala, ukuhlolwa kochwepheshe nokunakekela kufanele kwenziwe ngesikhathi.
