Iyini i-sprocket ye-crankshaft yemoto
I-sprocket ye-crankshaft yezimoto iyisici esibalulekile enjinini. Umsebenzi wayo oyinhloko ukushayela i-camshaft ukuze ijikeleze nge-timing chain, ngaleyo ndlela ilawule ukusebenza kwesitimela se-valve. I-sprocket ye-crankshaft ivame ukufakwa ku-crankshaft futhi ixhunywe ku-camshaft sprocket nge-timing chain ukuqinisekisa ukusebenza okuhlelekile kwazo zonke izingxenye zenjini.
Isakhiwo kanye nomgomo wokusebenza
Ama-sprocket e-crankshaft avame ukwenziwa ngezinto zensimbi futhi anamandla aphezulu nokuqina. Afakwa ku-crankshaft futhi axhunywe ku-camshaft sprocket nge-timing chain. I-timing chain iqhutshwa yi-crankshaft futhi isebenzisa i-hydraulic tensioner ukugcina ukucindezeleka okufanele, ukuqinisekisa ukudluliselwa okubushelelezi nokuthembekile. I-timing chain idlulisela amandla nge-sprocket, iqhuba i-camshaft ukuthi ijikeleze futhi ngaleyo ndlela ilawule ukuvulwa nokuvalwa kwama-valve ukuqinisekisa ukusebenza okuvamile kwenjini.
Ukugcinwa nokunakekelwa
Njengoba iketanga lesikhathi lenziwe ngezinto zensimbi futhi lingadingi ukugcotshwa, empeleni alidingi ukulungiswa ngesikhathi sokusetshenziswa. Kodwa-ke, ukuqinisekisa ukusebenza kwalo okuvamile, kuyadingeka ukuhlola njalo ukucindezeleka nokuguguleka kweketanga ukuqinisekisa ukulingana okuhle phakathi kwazo zonke izingxenye nokugwema amaphutha abangelwa ukukhululeka noma ukuguguleka .
Umsebenzi oyinhloko we-crankshaft sprocket emotweni ukuqinisekisa ukuthi i-valve ifika ngesikhathi lapho injini isebenza, okwenza ukuvulwa nokuvalwa kwama-valve okungenisa kanye nawokukhipha umoya kuhambisana nokuhamba kwe-piston.
Ngokukhethekile, i-sprocket ye-crankshaft ixhuma izingxenye ezibalulekile ezijikelezayo zenjini njenge-crankshaft kanye ne-camshaft ngeketanga, iqinisekisa ukusebenza kwazo okuhambisanayo, ngaleyo ndlela ilawula ngokunembile izikhathi zokuvulwa nokuvalwa kwama-valve kanye nochungechunge lokusha.
Isimiso sokusebenza
Umgomo osebenzayo we-crankshaft sprocket ukudlulisa ukunyakaza kokujikeleza kwe-crankshaft ku-camshaft ngeketanga, ngaleyo ndlela kulawula ukuvulwa nokuvalwa kwamavalvu. Lapho i-crankshaft ijikeleza, iketanga liqhuba i-crankshaft sprocket ukuthi ijikeleze, kanti i-crankshaft sprocket bese iqhuba i-camshaft ukuthi ijikeleze ngeketanga. I-CAM ku-camshaft izocindezela indlela yevalvu, ibangele ukuthi amavalvu avuleke futhi avalwe ngesikhathi. Ngale ndlela, izinqubo zokungenisa nokukhipha injini zingavumelaniswa ngokuphelele nokunyakaza kwe-piston, kuqinisekiswe ukusebenza kahle kwenjini.
Ukugcinwa nokunakekelwa
Ukuqinisekisa ukusebenza okuvamile kwe-crankshaft sprocket, kudingeka ukuhlolwa nokugcinwa okuvamile. Izinyathelo ezithile zifaka:
Ukugcotshwa kwe-Youdaoplaceholder0 : Qinisekisa ukuthi iketanga kanye ne-sprocket kugcotshwe kahle ukuze kuncishiswe ukuguguleka nokungqubuzana.
I-Youdaoplaceholder0 Lungisa ukucindezeleka : Hlola njalo ukucindezeleka kweketanga ukuqinisekisa ukuthi lisebenza ngaphansi kokucindezeleka okufanele futhi ugweme ukuguguleka okungavamile okubangelwa ukukhululeka kakhulu noma ukuqina kakhulu.
Ukuhlanza i-Youdaoplaceholder0 : Gcina i-sprocket kanye neketanga kuhlanzekile ukuze uvimbele ukungcola ukuthi kungangeni futhi kubangele ukuguguleka noma ukuminyana.
I-Youdaoplaceholder0 Shintsha izingxenye ezigugile : Hlola njalo ukuguguleka kwama-sprocket namaketanga, bese ushintsha izingxenye ezigugile kakhulu ngesikhathi esifanele ukuze uvimbele ukwehluleka kwenjini okubangelwa ukwehluleka kwezingxenye .
Izimpawu eziyinhloko zephutha le-crankshaft sprocket emotweni ukudlidliza okukhulu kwenjini, ukukhanya kwephutha kuyakhanya, kanye namakhodi ephutha atholakala ngethuluzi lokuxilonga yi-P0016 (indawo yokufaka i-camshaft kanye ne-crankshaft ayifani) kanye ne-P0012 (i-VVT yokungenisa ayikho esimweni esihleliwe lapho iqala).
Lawa makhodi amaphutha abonisa ukuthi kungase kube nezinkinga ngohlelo lwesikhathi noma i-sprocket ye-VVT.
Imbangela yokwehluleka
Inkinga yesistimu yesikhathi ye-Youdaoplaceholder0 : Kungaba yinkinga ngesistimu yesikhathi, njengokufakwa okungalungile kwe-camshaft, i-crankshaft, kanye ne-timing chain, noma ukuhlaziywa okungajwayelekile kwesignali yesensa yesikhundla yi-ECU .
Inkinga ye-sprocket ye-Youdaoplaceholder0 VVT : Kunenkinga ngokulawulwa kwevolumu kawoyela ekamelweni elingaphambili kanye negumbi lokulaxa le-sprocket ye-VVT. Kungase kube ngenxa yevalvu yokulawula uwoyela ebambekile noma indlela kawoyela ivinjiwe, okubangela ukuthi i-sprocket ye-VVT yehluleke ukufinyelela endaweni ehleliwe .
Izindlela zokuxilonga
I-Youdaoplaceholder0 Hlola uhlelo lwesikhathi : qinisekisa ukuthi i-camshaft, i-crankshaft kanye ne-timing chain kufakwe kahle yini. Ngemva kokukhipha izinkinga zokufaka, hlola futhi ukuthi inzwa yendawo kanye nokuhlaziywa kwesignali ye-ECU kujwayelekile yini .
I-Youdaoplaceholder0 Hlola i-sprocket ye-VVT : hlukanisa i-valve yokulawula uwoyela, susa noma yiziphi izingcezu zensimbi ezingaba khona noma ezinye izinsalela, qinisekisa ukuthi indlela kawoyela ayithintekile, faka kabusha bese uhlola ukuthi iphutha selixazululiwe yini .
isinyathelo sokuvimbela
I-Youdaoplaceholder0 Ukuhlolwa nokugcinwa okuvamile: Hlola njalo isimo samafutha okugcoba ukuqinisekisa ukuthi uchungechunge kanye ne-sprocket kugcotshwe ngokwanele, kunciphisa ukungqubuzana kanye nokuguguleka.
I-Youdaoplaceholder0 Lungisa ukuqina kweketanga : Qinisekisa ukuthi ukuqina kweketanga kungaphakathi kwebanga elinconywayo futhi ugweme ukukhululeka kakhulu noma ukuqina kakhulu .
I-Youdaoplaceholder0 Khetha uwoyela wokugcoba ofanele : Sebenzisa uwoyela wokugcoba ofanele bese uwugcoba ngemvamisa enconywayo .
