Ithetha ukuthini i-crankshaft sensor yemoto?
I-crankshaft sensor, eyaziwa ngokuba yi-crankshaft position sensor, yi-core sensor kwinkqubo yolawulo lwe-elektroniki yenjini. Isetyenziswa kakhulu ukubona indawo yokujikeleza kwe-crankshaft, isignali ephezulu esembindini ye-piston, kunye nesantya senjini, kwaye inika idatha ebalulekileyo kwiyunithi yolawulo lwenjini (ECU) ukulawula ixesha lokutsha kunye nexesha lokujova ipetroli. Umgaqo wokusebenza we-crankshaft sensor uxhomekeke kuhlobo lwayo, oluquka ikakhulu uhlobo lokungeniswa kwe-magnetic-electric, uhlobo lwe-Hall effect, kunye nohlobo lwe-photoelectric. Uhlobo lokungeniswa kwe-magnetic-electric luvelisa imiqondiso nge-electromagnetic induction, uhlobo lwe-Hall effect luchonga indawo kusetyenziswa utshintsho lwe-Hall voltage, kwaye uhlobo lwe-photoelectric ludlulisela ulwazi ngokuvalwa kwemingxuma yokukhanya kunye nokuguqulwa kwesignali ye-photoelectric; ezi sensor zihlala zisebenza kunye ne-camshaft position sensor ukumisela ngokuchanekileyo i-angle ye-crankshaft kunye ne-angular velocity, ukuqinisekisa ukuchaneka kwexesha lokutsha kunye nexesha lokujova ipetroli. Umsebenzi wayo ubalulekile, kungekuphela nje ukumisela amaxesha okutsha kunye nokujova ipetroli, kodwa kunye nokuhlalutya ukutshintsha kwe-angle ye-crankshaft ukubona ukungasebenzi kakuhle kwenjini kunye nokubonelela ngenkxaso yedatha yolawulo olungasebenziyo kunye nolawulo lokuphuma kwepetroli. Ekugcinweni kweemoto, iimpazamo eziqhelekileyo ze-crankshaft sensor ziquka ukulahleka kwesiginali okanye ukuphazamiseka, okunokubangela ubunzima ekuqaliseni injini, ukungahlali kakuhle, okanye ukulahleka kwamandla; iindlela zokufumanisa zihlala ziquka ukujonga uqhagamshelo lweentambo, iimpawu zokuphuma, okanye amaxabiso okumelana ne-sensor ukuqinisekisa ukusebenza okuqhelekileyo.
Iimpazamo eziqhelekileyo ze-crankshaft sensor ziquka ukulahleka kwesiginali okanye ukuphazamiseka, okunokubangela ubunzima ekuqaliseni injini, ukungahlaliseki kakuhle, okanye ukulahleka kwamandla; iindlela zokufumanisa zihlala ziquka ukujonga uqhagamshelo lweentambo, iimpawu zokuphuma okanye amaxabiso okumelana ne-sensor ukuqinisekisa ukusebenza okuqhelekileyo.
Ukungasebenzi kakuhle kwe-crankshaft sensor kunokukhokelela kwiimpawu ezinje ngokusilela kokuqala kwenjini, ukutshaya okungahambi kakuhle kunye nexesha lokufakwa kwepetroli, ukwanda kokungcangcazela kwenjini kunye nokuvalwa kokukhawulezisa, njl.njl., kwaye kuyimfuneko ukuyijonga nokuyitshintsha ngexesha.
Iimpawu ezingaqhelekanga zokuqalisa kunye notyando
Ukungasebenzi kakuhle kwe-crankshaft sensor kuchaphazela ngokuthe ngqo ixesha lokutsha kunye nexesha lokufaka ipetroli kwinjini, kwaye kubonakala ngolu hlobo:
Ubunzima bokuqalisa okanye ukungakwazi ukuqala: Ngenxa yokungakwazi kwesensor ukubonelela ngesignali yokuma kwe-crankshaft, i-ECU (iyunithi yokulawula injini) ayikwazi ukulawula ukutsha kunye nokufakwa kwepetroli, nto leyo ebangela ukuba ixesha lokuqalisa libe ngaphezulu kwemizuzwana emi-5 okanye ukungasebenzi kaninzi kokutsha, kwaye kwiimeko ezinzima, umbane ophezulu kunye nokufakwa kwepetroli kuyacinywa.
Ukungcangcazela kwenjini kunye nokulahleka kwamandla:
Ukungenzi nto okungazinzanga: Isantya senjini sitshintshatshintsha ngokungacwangciswanga phakathi kwe-600-1200 rpm, kwaye isandi sesiteringi siyabonakala.
Ukukhawulezisa okubuthathaka: Isantya senjini kunzima ukusidlula i-3000 rpm xa unyuka, kwaye umbhobho wokukhupha umoya unokukhupha izandi eziphumayo okanye umsi omhlophe (ngenxa yokutsha okungaphelelanga).
Umngcipheko wokucima kwenjini ngexesha lokuqhuba: Ukuphazamiseka kwamandla ngequbuliso kunokwenzeka ngexesha lokuqhuba ngesantya esiphezulu, kwaye i-ECU ingena kwimo yokukhusela ize icime ngenkani, nto leyo eyingozi kakhulu.
Imisebenzi yenkqubo kunye neempawu zesilumkiso
Ukungasebenzi kakuhle kwenkqubo ye-elektroniki:
Imisebenzi efana nolawulo lokuhamba ngenqanawa, ukuyeka ukuqala ngokuzenzekelayo, kunye nokuqhoboshela i-exhaust iyaphazamiseka ngokuthe ngqo.
Isibane sempazamo sihlala sivuliwe okanye sikhanya, kwaye ezinye iimodeli zibangela ii-alamu zonxibelelwano ze-EPS/ABS.
Ukukhutshwa komoya okungaqhelekanga kunye nokusetyenziswa kwepetroli: Umsi omhlophe oqhubekayo onevumba elifana nepetroli uyaphuma, isenzi seoksijini sixela ikhowudi yempazamo yokungalingani komxube wepetroli, kwaye ukusetyenziswa kwepetroli kunyuka kakhulu.
Umahluko kwizibonakaliso zobunzima bempazamo
Ingxaki encinci: Isithuthi sibuthathaka xa siqhuba sinyuka intaba, impendulo ye-accelerator iyacotha, kodwa ukusebenza kwamandla akutshintshi kakhulu.
Ingxaki enkulu: Ayikwazi ukuqala, kwaye injini ingenza isandi sepiston ebetha ivalvu (kwiimodeli ezindala).
Xa i-sensor ye-crankshaft position yenjini ingasebenzi, imoto iya kubonisa iimpawu ezifana nokuqalisa okungaqhelekanga, ukulahleka kombane, ukungcangcazela okwandileyo, kunye nokukhanya kwe-fault okuvuliweyo, ngolu hlobo lulandelayo:
Ukuqalisa okungaqhelekanga
Ukulahleka kwesignali yesenzwa kuya kubangela ukutsha okungahambi kakuhle kunye nexesha lokufakwa kwepetroli, okubonakala ngolu hlobo:
Ubunzima bokuqalisa ngokubandayo: Kuthatha imizamo emininzi ukuze kuvuthelwe, kwaye kwiimeko ezinzima, akunakwenzeka kwaphela ukuba kuvuthelwe.
Ulwandiso lwexesha lokuqalisa: Ixesha lokujikeleza kwenjini lide kakhulu, kwaye kusenokubakho izandi ezingaqhelekanga.
Iingxaki zokuqhuba
Ingxaki ibangela ukungalingani kwenkqubo yamandla, kwaye iimpawu eziqhelekileyo ziquka:
Ukukhawulezisa okubuthathaka: Impendulo yokunyuka okanye ukudlula iyancipha, kwaye i-accelerator pedal kufuneka icinezelwe ngokupheleleyo ukuze inyuse isantya.
Ukungcangcazela okungasebenziyo: Injini iyangcangcazela ngamandla xa ipakwe, kwaye ivili lokuqhuba okanye isihlalo sivakala ngokucacileyo.
Ukukhutshwa komsi omhlophe: Ukutsha okungaphelelanga kubangela ukuba umsi omhlophe uphume kumbhobho wokukhupha umoya. Ukwanda kokusetyenziswa kwepetroli: Ngenxa yokulawulwa okungachanekanga kokufakwa kwepetroli, ukusebenza kakuhle kwepetroli kuyehla.
Ukusilela kwenkqubo ye-elektroniki
Imiqondiso yenzwa engaqhelekanga iya kubangela ukusabela kwetsheyini:
Isibane sempazamo siyakhanya: Isibane sempazamo yenjini kwideshibhodi sihlala sivuliwe okanye sikhanya.
Ukungasebenzi kakuhle: Iinkqubo zokulawula ukuhamba ngenqanawa kunye neebhuleki zokukhupha umoya azinakusetyenziswa.
Umngcipheko wokuvalwa kwenjini: Injini isenokucima ngequbuliso ngelixa iqhuba ngesantya esiphezulu, nto leyo ebeka iingozi zokhuseleko.
