Yintoni iplagi yesenzi yeoyile yemoto?
I-automotive oil pressure sensor, eyaziwa ngokuba yi-oil pressure sensor, yinxalenye ebalulekileyo yokujonga kwinkqubo yokuthambisa injini. Umsebenzi wayo ophambili kukujonga rhoqo uxinzelelo lwangaphakathi lwe-oyile yenjini nokuguqula isignali yoxinzelelo efunyenweyo ibe sisignali yombane, ethi emva koko idluliselwe kwideshibhodi yesithuthi okanye kwiyunithi yokulawula injini (ECU).
Xa uxinzelelo lweoyile lungaqhelekanga (njengokuba luphantsi kakhulu), i-sensor yoxinzelelo lweoyile iya kuqalisa isibane se-alamu yoxinzelelo lweoyile kwideshibhodi, ilumkise umqhubi ukuba anikele ingqalelo ngokukhawuleza ukuze athintele umonakalo omkhulu kwinjini ngenxa yokungathambisa ngokwaneleyo. Ke ngoko, ibizwa ngokuba "ngumlindi wokhuseleko" ngokuqinisekisa ukusebenza kakuhle kwenjini.
Imisebenzi ephambili
Ukubeka esweni uxinzelelo: Ngokusebenzisa i-diaphragm yoxinzelelo lwangaphakathi okanye i-sensor chip, iyaziva utshintsho kuxinzelelo lweoyile ize iziguqule zibe ziimpawu zombane.
Ukuhanjiswa kwesignali: Ithumela imiqondiso yombane kwi-oyile pressure gauge ekwideshibhodi ukuze ibonise ixabiso loxinzelelo lwexesha langempela.
Ukuqalisa i-alamu: Xa uxinzelelo lungaphantsi komda wokhuseleko, isekethe ye-alamu iyavulwa, ikhanyisa isibane sesilumkiso.
Ulawulo oluncedisayo: Kwezinye izithuthi, i-ECU iya kulungisa imeko yokusebenza kwenjini ngokusekelwe kulwazi loxinzelelo lweoyile, njengokunciphisa amandla okukhupha ukuze kukhuselwe injini.
Inkcazo emfutshane yomgaqo wokusebenza
I-oyile pressure sensor idla ngokuba ne-chip ye-film pressure sensor chip kunye ne-signal processing circuit. Xa injini isebenza, i-oyile pressure ityhala i-diaphragm ngaphakathi kwi-sensor, itshintsha ukumelana kwayo okanye ixabiso le-capacitance, ivelise umahluko we-voltage, eguqulwa ibe yi-voltage signal, ikhuliswe kwaye icutshungulwe ngaphambi kokuba iphume. Ukuba i-pressure iphantsi kakhulu, i-alamu circuit iya kuqalisa isilumkiso ngoko nangoko.
Iimpawu eziqhelekileyo zeziphene
Isibane se-alamu yoxinzelelo lweoyile sihlala sivuliwe okanye sikhanya rhoqo
Uxinzelelo lweoyile oluboniswa kwideshibhodi alukho okanye luyatshintshatshintsha ngamandla
Injini yenza ingxolo engaqhelekanga, amandla ayancipha, kwaye ukusetyenziswa kwepetroli akuqhelekanga (mhlawumbi kungenxa yokungaqondi kakuhle kwe-ECU kunye nokunqongophala kwamandla)
Isalathisi segeyiji yoxinzelelo sikhomba phezulu okanye isibane se-alamu asicimi ngexesha lovavanyo lokubeka umhlaba phantsi
Isalathiso sendawo
Isixhobo sokuvavanya uxinzelelo lweoyile sidla ngokuba kufutshane nesihluzi seoyile, kwaye indawo ethile iyahluka ngokuxhomekeke kwimodeli yesithuthi. Sifumaneka rhoqo kwi:
Ngaphezulu okanye ecaleni kwesihluzi seoyile
Kufuphi nesihlalo sesihluzo seoyile ngasemva kwebhloko yesilinda yenjini
Kwezinye iimodeli zezithuthi, isenokuba kufutshane nesigqubuthelo sesilinda okanye uqhagamshelo lombhobho wokungenisa
Qaphela: Iinkcukacha zentambo yenzwa, imida yoxinzelelo, kunye neendlela zocingo zinokwahluka kwiimodeli ezahlukeneyo zezithuthi. Xa utshintsha, kuyacetyiswa ukusebenzisa iindawo zokuqala okanye ezisemgangathweni ze-OEM, kwaye uqinisekise ukusetyenziswa ngokufanelekileyo kwe-sealant kunye ne-torque ukuthintela ukuvuza kweoyile.
Ukungasebenzi kakuhle kwe-oyile yemoto (oko kukuthi, i-oyile ye-oyile ye-oyile) kuya kuchaphazela ngqo ukujonga inkqubo yokuthambisa injini. Ukuba ayilungiswanga ngokukhawuleza, inokukhokelela kumonakalo omkhulu woomatshini. Ezi zilandelayo ziimpawu eziqhelekileyo zempazamo, izizathu, kunye nezisombululo.
Iimpawu eziphambili zempazamo
Isibane sesilumkiso sedeshibhodi sivuliwe: Emva kokuba imoto iqalile, isibane sesilumkiso soxinzelelo lweoyile sihlala sivuliwe (hayi ukuze uzihlole okwethutyana), okanye sikhanya ngokuphindaphindiweyo ngelixa uqhuba. Ezinye iimodeli ziya kubonisa imiyalezo efana nokuthi "Uxinzelelo lweoyile ephantsi" okanye "Ukusilela kweSensor", ngelixa iimodeli eziphezulu zinokubonisa ukutsiba okungaqhelekanga kumaxabiso oxinzelelo lweoyile (njengokubonisa ngaphantsi kwe-0.5 bar okanye ngaphezulu kwe-10 bar xa ungenzi nto).
Ukungasebenzi kakuhle kwenjini: Malunga nama-60% eemeko zempazamo ziya kuhamba nokwehla kwamandla, okubonakala njengokukhawulezisa kancinci kunye nokuphendula okulibazisekileyo xa udlula imoto; i-ECU yezinye izithuthi iya kubangela indlela yokukhusela, inciphise isantya senjini (ngesiqhelo ingadluli kwi-3000 rpm), okanye ibangele ukushukuma okanye ubunzima obuqala phantsi kweemeko ezibandayo.
Ingxolo engaqhelekanga yenjini kunye nomonakalo ofihlakeleyo: Ngenxa yokungathambisa ngokwaneleyo, izandi zokungqongqoza zinokwenzeka kwisihlalo se-camshaft okanye se-valve, okanye ingxolo engaqhelekanga evela kwikhonkco lexesha. Ukusilela kwexesha elide kunokukhokelela kumonakalo ongenakuguqulwa ofana nokuguguleka kweebheringi, imikrwelo yeringi yepiston, kunye neendleko zokulungisa zihlala zidlula i-5,000 yuan.
Iikhowudi zempazamo kunye nokuhamba kwedatha okungaqhelekanga: Ukusebenzisa isixhobo sokuxilonga i-OBD, iikhowudi ezithile zempazamo zinokufundwa, ezifana ne-P01CA (umbane ogqithisileyo kwisekethe yesensa yoxinzelelo lweoyile) okanye i-P01CB (umbane ophantsi). Kwiimeko eziqhelekileyo, ukuphambuka phakathi koxinzelelo lweoyile oluvakalayo yisensa kunye nedatha efunyenwe yi-ECU kufuneka ibe yi-≤ 0.1 bar. Ukuba idlula kwi-0.3 bar, kunokugqitywa ukuba isensa ayiqhelekanga.
Ezinye iimpawu: Ezinye izithuthi zinokufumana ukusetyenziswa kwepetroli okwandileyo, isibane se-injini (Check Engine) esihlala sivuliwe rhoqo, okanye ukufundwa koxinzelelo lweoyile okungaqhelekanga kwideshibhodi (njengomboniso osisigxina we-0.99 bar ngesantya esingasebenziyo).
Izizathu eziqhelekileyo zokuphosakala
Ukungasebenzi kakuhle kweplagi ye-oyile sensor yenye yezizathu. Ngokuqhelekileyo, yingxaki yenkqubo ebangela ukuba ukubhaqwa kungaqhelekanga:
Iingxaki zeoyile: Ubuninzi beoyile obungonelanga, ioyile engcolileyo, ukuqina okungaqhelekanga (okuncinci kakhulu okanye okutyebileyo kakhulu), umgangatho weoyile ophantsi.
Ukusilela kwesekethe yeoyile kunye namacandelo: Ukuvuza kwepayipi yeoyile, isihluzi seoyile esivalekileyo, ipompo yeoyile egugileyo, ivalvu ye-bypass okanye intwasahlobo yevalvu ethintela uxinzelelo ukuba ithambile kakhulu/ixinene/ ibhola yentsimbi yonakele.
Isekethe kunye nesensa ngokwayo: Isekethe emfutshane, isekethe evulekileyo, unxibelelwano olubi kwisekethe yangaphakathi yesensa, okanye ukuguga kwesensa, iringi yokutywina eyonakeleyo ekhokelela ekuvuzeni kweoyile, ukungena kwamanzi/ukungena kokungcola.
Ezinye izinto: Ubushushu obugqithisileyo benjini, indawo engafanelekanga yokufakelwa, i-voltage yombane engazinzile, indawo evulekileyo kakhulu phakathi kwe-crankshaft kunye ne-bearing, njl.
Iindlela zokuphendula kunye nezisombululo
Jonga ngoko nangoko inqanaba leoyile: Ukuba ioyile incinci kakhulu, yongeza kwimida ephezulu nesezantsi yedipstick. Ukuba inqanaba liqhelekile kodwa isibane sokulumkisa sisavuliwe, musa ukuqhubeka nokuqhuba.
Tshintsha ngeoyile esemgangathweni ophezulu: Sebenzisa ioyile epheleleyo eyenziweyo ehlangabezana neemfuno zesithuthi. Kuphephe ukusebenzisa iimveliso eziphantsi okanye eziphelelwe lixesha.
Uhlolo lobuchwephesha: Kucetyiswa ukuba imoto ihlolwe kwindawo yokulungisa yobuchwephesha kwiiyure ezingama-48, kugxilwe ekujongeni:
Ixabiso lokumelana ne-sensor (uluhlu oluqhelekileyo ludla ngokuba yi-50–1000 Ω, olutshintsha ngokweqondo lobushushu).
Imeko yesekethe yeoyile, ipompo yeoyile, ivalvu yokunciphisa uxinzelelo, njl.
Nokuba uqhagamshelo lwesekethe luqhelekile na.
Tshintsha i-sensor: Ukuba i-sensor iqinisekisiwe ukuba yonakele, yitshintshe ngenxalenye yomgangatho wokuqala okanye ethembekileyo, kwaye uqinisekise ukuba ufakelo olufanelekileyo.
Amanyathelo okuthintela: Tshintsha rhoqo isihluzi seoyile kunye neoyile, kuphephe ukukhawulezisa ngokukhawuleza kunye nokuqhobosha, ukunciphisa impembelelo kwinjini, kwaye uphuhlise umkhwa wokulungisa rhoqo.
Isikhumbuzo esibalulekileyo: Iplagi ye-oyile sensor ayithambiseli injini ngokuthe ngqo, kodwa ukungasebenzi kwayo kuya kuthintela umniniyo ekubeni ayazi uxinzelelo lwe-oyile lokwenyani. Ukuba iqhutywa ngenxa yokungaqondi kakuhle, inokubangela ukuba injini "ityhafise i-bearing", kwaye iziphumo zibe zimbi kakhulu kunokutshintsha i-sensor.
