Kwenzekani uma ipulaki yesensa kawoyela yonakele?
Uma inzwa kawoyela (inzwa yokucindezela kawoyela) yonakele, imoto izobonisa izenzakalo ezifana ne-alamu yensimbi, ukusebenza kwenjini okungavamile, kanye nokuvuza kawoyela noma amakhodi athile amaphutha.
I-alamu yensimbi kanye nokukhubazeka kokubonisa
Isibani se-alamu kawoyela sihlala sivuliwe njalo: Lokhu kuyindlela eqondile nevamile kakhulu yokusabela, okubonisa ukuthi uhlelo luthola ukucindezela kawoyela okungavamile.
Isibani sephutha lenjini siyavuleka: Ikhompyutha yemoto (ECU) ingase ibangele isexwayiso sephutha lenjini ngenxa yokwamukela isignali engavamile.
Isibonisi sokucindezela uwoyela esingalungile: Isibonakaliso sokucindezela uwoyela kudeshibhodi singase sibonise inani elizinzile (njengokubonisa njalo u-0.99) noma ukuphambuka okuphawulekayo ekucindezelweni kwangempela.
Ukusebenza kwenjini okungavamile
Ukulahlekelwa amandla kanye nokulinganiselwa kokusebenza: Ngenxa yokuqalisa kwendlela yokuvikela ukuthambisa, amandla enjini kanye nesivinini kuzoncipha, okwenza ukusheshisa kube buthaka, kuzizwe "kuntula amandla", futhi kube nokulinganiselwa kwesivinini.
Ukungazinzi kwenjini okungenzi lutho noma ukuvala injini okungavamile: Kungase kube nokujikijela okungasebenzi, isivinini esishintshashintshayo, noma ezimweni ezimbi kakhulu, injini ingase izivale ngokuzenzakalelayo ukuze izivikele.
Imisindo engavamile kanye nokudlidliza: Ngenxa yokungagcwalisi ngokwanele, ukungqubuzana kwangaphakathi kwenjini kuyanda, okubangela ukungqubuzana kwensimbi kanye nokudlidliza okungavamile.
Ukusetshenziswa kukaphethiloli kunganda: Ukugcotshwa kabi kwesikhathi eside kuholela ekugugeni okukhulu kwenjini, okungase kubangele ukwanda kokusetshenziswa kukaphethiloli.
Ezinye izimpawu ezihlobene
Ukuvuza okungenzeka kukawoyela: Uma uphawu lwenzwa lonakele (njenge-gasket yangaphakathi ephukile), kungase kube nokuvuza kukawoyela endaweni yokufaka.
Funda amakhodi ephutha athile: Ngokuxhumanisa ikhompyutha yemoto nethuluzi lokuxilonga, amakhodi ephutha afana ne-"P01CA" (i-voltage ephezulu yenzwa yokucindezela uwoyela) angafundwa ngokukhomba ngqo leli phutha.
Inzwa yokucindezela uwoyela ifakiwe endaweni eyinhloko yamafutha enjini. Uma injini isebenza, idivayisi yokulinganisa ingcindezi ithola ingcindezi kawoyela bese iguqula isignali yokucindezela ibe isignali kagesi ethunyelwa kwisekethe yokucubungula isignali. Ngemva kokukhulisa i-voltage kanye nokukhulisa ugesi, isignali yokucindezela ekhulisiwe ixhunywe ngomugqa wesignali kuya kwisikhombisi sokucindezela uwoyela, ishintsha isilinganiso samanje ngamakhoyili amabili ngaphakathi kwesikhombisi sokucindezela uwoyela ukuze ibonise ingcindezi kawoyela yenjini. Isignali yokucindezela ekhulisiwe nayo iqhathaniswa ne-voltage ye-alamu esethwe kwisekethe ye-alamu. Uma ingaphansi kwe-voltage ye-alamu, isekethe ye-alamu ikhipha isignali ye-alamu bese ikhanyisa isibani se-alamu ngentambo ye-alamu.
Indlela yokuxhumanisa yenzwa yokucindezela uwoyela kagesi ifana ncamashi neyenzwa yendabuko yomshini, ekwazi ukufaka esikhundleni inzwa yokucindezela yomshini futhi ixhumeke ngqo esibonisini sokucindezela uwoyela wemoto kanye nesibani se-alamu esinomfutho ophansi ukukhombisa ukucindezela uwoyela wenjini kadizili futhi inikeze isignali ye-alamu enomfutho ophansi. Uma kuqhathaniswa nenzwa yendabuko yokucindezela uwoyela we-piezoresistive, inzwa yokucindezela uwoyela wezimoto kagesi inezinzuzo zokungabi nezingxenye ezihambayo zomshini (okungukuthi, azikho oxhumana nabo), ukunemba okuphezulu, ukuthembeka okuphezulu, kanye nokuphila isikhathi eside, futhi ihambisana nezidingo zokuthuthukiswa kwe-elekthronikhi yezimoto.
Ngenxa yendawo yokusebenza enzima yezimoto, izinzwa kudingeka zibe lukhuni kakhulu. Ekwakhiweni kwezinzwa zokucindezela uwoyela wezimoto zikagesi, akuzona nje kuphela amadivayisi okulinganisa ukucindezela amelana nokushisa okuphezulu, amelana nokugqwala, kanye nokunemba okuphezulu okudingeka kukhethwe, kodwa futhi nezingxenye ezinokwethenjelwa ezinobubanzi bokushisa bokusebenza okubanzi kudingeka kukhethwe. Ngaphezu kwalokho, kudingeka kuthathwe izinyathelo zokulwa nokuphazamiseka kwesekethe ukuze kuthuthukiswe ukuthembeka kwenzwa.
