Inzwa yoxinzelelo lokuthatha.
Isivamvo soxinzelelo lokuthatha umoya (ManifoldAbsolutePressureSensor), emva koku kubhekiselwa kuyo njenge-MAP. Idityaniswe kwi-intake manifold kunye netyhubhu yokucoca, kunye nomthwalo ohlukeneyo wesantya se-injini, utshintsho lwe-vacuum kwi-intake manifold luyanyanzeliswa, emva koko utshintsho lokumelana kwi-sensor luguqulwa lube ngumqondiso wombane we-ECU ukuya. lungisa isixa sokutofa kunye ne-engile yexesha lokutshisa.
Kwi-injini ye-EFI, i-sensor yoxinzelelo lwe-intake isetyenziselwa ukufumanisa umthamo wokungena, okubizwa ngokuba yi-D-injection system (uhlobo lwe-velocity density). I-sensor yoxinzelelo lwe-intake ibona umthamo wokungena awubonakali ngokuthe ngqo njenge-sensor yokungena, kodwa isebenzisa ukubonwa ngokungathanga ngqo, kwaye iphinda ichaphazeleke ngezinto ezininzi, ngoko kukho iindawo ezininzi ezahlukeneyo ekufumaneni nasekugcinweni kune-sensor yokungena, kwaye isiphene esenziwayo sikwanazo ncakasana.
Isivamvo soxinzelelo lokuthatha sibona uxinzelelo olupheleleyo lwendlela yokungena emva kwevalve ye-throttle, ebona utshintsho olupheleleyo loxinzelelo kwi-manifold ngokwesantya senjini kunye nomthwalo, emva koko iguqule amandla ombane kwiyunithi yokulawula injini (ECU), kwaye I-ECU ilawula ubungakanani benaliti yamafutha esisiseko ngokobungakanani bombane wophawu.
Inzwa yoxinzelelo lwe-intake luhlobo lwenzwa esetyenziselwa ukubeka esweni utshintsho loxinzelelo kwinkqubo yokuthatha injini. Idlala indima ebalulekileyo kwiimoto okanye kwezinye izixhobo ze-injini yokutsha yangaphakathi.
Imisebenzi ephambili ye-sensor yoxinzelelo lokuthatha yile ilandelayo:
1. Ukulungiswa kwamafutha: I-sensor yoxinzelelo lwe-intake inokulinganisa uxinzelelo kumbhobho wokungenisa kwaye unikeze idatha yoxinzelelo oluchanekileyo kwiyunithi yokulawula injini. Ngokusekelwe kule datha, iyunithi yokulawula inokulungelelanisa ukunikezelwa kwepetroli ukubonelela ngokusebenza okuphezulu kokutsha kunye nokusebenza.
2. Ukulawulwa kwe-injini: Umqondiso we-sensor yoxinzelelo lokuthatha usetyenziselwa ukuphuhliswa kwezicwangciso zokulawula injini. Lungisa ixesha lokucima, ixesha levalvu, kunye nezinye iiparamitha eziphambili ezisekwe kutshintsho kuxinzelelo lokuthatha amandla angcono, uqoqosho lwamafutha, kunye nolawulo lokukhutshwa.
3. Ukubona impazamo: I-sensor yoxinzelelo lwe-intake inokubeka iliso kwimeko yokusebenza kwenkqubo yokuthatha kwaye ithumele ikhowudi yephutha kwiyunithi yokulawula xa kwenzeka i-anomaly. Oku kunceda ukufumanisa kunye nokuxilonga iingxaki ezinxulumene nenkqubo yokuthatha, njengokuvuza komoya kumbhobho wokungena, ukungaphumeleli kwenzwa okanye uxinzelelo olungaqhelekanga.
Kukho konke, i-sensor ye-intake pressure sensor inikezela ngedatha echanekileyo yokulawula injini ngokulinganisa utshintsho loxinzelelo kwi-duct yokungenisa ukunyusa ukusebenza kakuhle kokutsha, ukuphuma kwamandla kunye nokulawula ukukhutshwa. Idlala indima ebalulekileyo ekusebenzeni okuqhelekileyo kunye nokuxilongwa kwempazamo ye-injini.
Ziziphi iimpawu zenzwa yeqondo lokushisa eliphukileyo?
01 Injini iyadika
I-injini ebuthuntu luphawu olucacileyo lwenzwa engalunganga yobushushu bokungena. Xa isignali yobushushu bamanzi enikezelwa yi-sensor yeqondo lokushisa lomoya kwi-ECU iphezulu kuneqondo lokushisa lamanzi langempela, umxube uya kuba mncinci, okubangela ukukhawuleza kwe-injini kunye nokunciphisa amandla. Ukongeza, ngenxa yokuba i-ECU ayifumani uphawu oluchanekileyo lobushushu bamanzi, umxube unokuba mkhulu kakhulu okanye ube mncinci kakhulu, okwenza kube nzima ukuqala imoto ebandayo. Ngoko ke, ukusombulula le ngxaki, ngokuqhelekileyo kuyimfuneko ukugqithisa i-sensor yeqondo lokushisa lomoya.
02 Awukwazi ukulawula ngokuchanekileyo inaliti yamafutha
Umonakalo kwi-sensor yeqondo lokushisa kuya kubangela ukungakwazi ukulawula ngokuchanekileyo i-injection fuel. Oku kungenxa yokuba i-sensor yobushushu bomoya othathayo inoxanduva lokujonga ubushushu bomoya ongena enjini kwaye idlulise olu lwazi kwiyunithi yokulawula i-elektroniki yesithuthi (ECU). I-ECU ihlengahlengisa umthamo wenaliti yamafutha ngokusekwe kule datha ukuze kuphuculwe ukusebenza kakuhle kwe-injini kunye nokusebenza kakuhle kwamafutha. Ukuba i-sensor yonakalisiwe, i-ECU ayiyi kukwazi ukufumana idatha echanekileyo yeqondo lokushisa lomoya, okubangela ukuba i-injection ye-fuel engafanelekanga. Oku akuchaphazeli ukusebenza kwe-injini kuphela, kodwa kunokukhokelela ekwandeni kokusetyenziswa kwamafutha.

Ifeni ihlala ibaleka okanye ayibaleki
Umonakalo wenzwa yeqondo lokushisa lomoya wokungena kunokubangela ukuba i-fan ijikeleze ngokuqhelekileyo okanye hayi. Xa kukho ingxaki kwinzwa yobushushu bokungena, ayikwazi ukufunda ngokuchanekileyo ubushushu obupholileyo be-injini, echaphazela iyunithi yokulawula i-fan. Ukuba ufundo lwesivamvo luphantsi, ifeni inokuqhubeka ibaleka kwilinge lokwehlisa ubushushu bokupholisa. Ngakolunye uhlangothi, ukuba ukufundwa kuphezulu, i-fan isenokungaqali, ibangele ukuba injini ishushu. Ngoko ke, ukuziphatha okungaqhelekanga kwefeni kunokuba ngumqondiso ocacileyo wokungaphumeleli kwenzwa yokushisa yomoya.
04 Isalathisi sobushushu bamanzi esingaqhelekanga
Isalathisi sokushisa kwamanzi esingaqhelekanga luphawu olucacileyo lwenzwa yokushisa yokungenisa umoya owonakeleyo. Xa kukho ingxaki kwinzwa yobushushu bokungena, isenokungakwazi ukufunda ngokuchanekileyo ubushushu obupholileyo be-injini, okukhokelela ekufundweni okungachanekanga kwesilinganisi sobushushu bamanzi. Oku kungachaneki kunokubangela ukuba umqhubi angayiqondi kakuhle imeko yobushushu be-injini, nto leyo echaphazela ukhuseleko lokuqhuba. Ngoko ke, xa isalathisi sokushisa kwamanzi sifunyenwe singaqhelekanga, i-sensor yeqondo lokushisa lomoya kufuneka ihlolwe ngokukhawuleza kunye nokulungiswa okufunekayo okanye ukutshintshwa.
