Sensor Yokakamiza Kulowa: "Diso la Deta" Lofunika Kwambiri la Injini
Sensa yokhudza kuthamanga kwa mpweya (yofupikitsidwa ngati sensa ya MAP) ndi gawo lofunika kwambiri la njira yopangira mafuta ya mtundu wa D m'mainjini opangira mafuta amagetsi, yomwe imagwira ntchito ngati "wofufuza kuthamanga kwa mpweya" wa injini. Imayang'anira nthawi zonse kusintha kwa kuthamanga kwa mpweya mu njira yopangira mpweya ndipo imapereka maziko ofunikira opangira zisankho pa chipangizo chowongolera injini (ECU).
Imalumikizidwa ku intake manifold kudzera mu chubu chopanda mpweya ndipo imatha kujambula molondola kusinthasintha kwa kuthamanga kwa mpweya mu intake manifold pansi pa mikhalidwe yosiyanasiyana yogwirira ntchito, kuisintha kukhala zizindikiro zamagetsi ndikuzitumiza ku ECU. Pakathamanga galimoto, kuthamanga kwa mpweya kumawonjezeka, ndipo sensa imatumiza chizindikiro mwachangu, chomwe ECU imawonjezera kuchuluka kwa mafuta kuti ipereke mphamvu yokwanira ya injini; ikachepetsa mphamvu ya mpweya, kuthamanga kwa mpweya kumachepa, ndipo ECU imachepetsa kulowetsa mafuta, kupewa kuwononga mafuta ndikuwonjezera kugwiritsa ntchito mafuta moyenera.
Zingathandizenso ECU kusintha nthawi yoyatsira, kulola kuti chisakanizocho chiziyaka bwino, kupeza bwino pakati pa mphamvu yotulutsa ndi yowongolera mpweya. Kwa injini zomwe zili ndi makina owongolera ma valve amagetsi, sensa yowunikira kuthamanga kwa mpweya ingagwiritsidwenso ntchito ngati njira yosungira zizindikiro zonyamula katundu, kuthandiza kusintha nthawi yotsegulira valavu yolowera mpweya ndikuwonjezera magwiridwe antchito a injini.
Chenjezo Lolephera: "Chenjezo la Thanzi" la Injini
Ngati sensa yoyezera kuthamanga kwa injini yalephera, mphamvu yogwirira ntchito ya injiniyo idzasokonekera, zomwe zimayambitsa zizindikiro zingapo zachilendo, zomwe zingabweretse mavuto pa magwiridwe antchito a galimoto komanso chitetezo cha galimotoyo.
Kulephera kwa sensa yosakhazikika pa injini yoyambira ndi yosakhazikika kungapangitse kuti ECU isathe kudziwa bwino kuchuluka kwa mphamvu yolowera, zomwe zimapangitsa kuti pakhale kusiyana pakati pa kuchuluka kwa mphamvu yolowera mafuta ndi mphamvu yolowera. Poyimitsa injini mozizira, injini ingafunike kuyesa kangapo kuti iyatse bwino, ndipo zizindikiro zimatha kusintha pang'ono ikatenthedwa, koma ikhoza kuzimitsidwa nthawi yomweyo injini ikayamba. Pa nthawi yosakhazikika, liwiro la injini limasintha kwambiri pakati pa 800-1000 rpm, ngakhale kugwedezeka ndi kuyima, mofanana ndi kulephera kwa silinda, koma kuyang'ana ma spark plugs ndi ma ignition coils kukuwonetsa zotsatira zabwinobwino, zomwe mwina zimayambitsidwa ndi signal drift^.
Kusalingana kwa Mphamvu ndi Kugwiritsa Ntchito Mafuta Pakuthamanga kwa injini, liwiro la injini limakwera koma liwiro la galimoto limawonjezeka pang'onopang'ono, zomwe zimapangitsa kuti "zimveke ngati zatha", ndi mphamvu yoyankha mochedwa kwambiri. Mphamvu ya mitundu ina ya 1.6L ikhoza kukhala yoipa kwambiri kuposa ya mitundu ya 1.0L. Izi zili choncho chifukwa sensa singathe kuyankha mwachangu kusintha kwa mphamvu ya intake throttle itatsegulidwa, ndipo kulowetsa mafuta kwa ECU kumachedwa, zomwe zimapangitsa kuti pakhale kusiyana kwa mphamvu. Nthawi yomweyo, cholakwikacho chingapangitse ECU kuweruza molakwika kuchuluka kwa intake, zomwe zimapangitsa kuti pakhale kusalingana kwa kuchuluka kwa kusakaniza, mwina kukhala kolemera kwambiri komwe kumayambitsa utsi wakuda kuchokera ku chitoliro chotulutsa utsi ndi kuyaka kosakwanira, kapena kukhala woonda kwambiri komwe kumayambitsa mphamvu yosakwanira. Mulimonsemo, kugwiritsa ntchito mafuta kudzawonjezeka kwambiri, ndipo kugwiritsa ntchito mafuta kwa magalimoto ena kumatha kukwera kuchokera pa 8L/100km kufika pa 12L/100km^.
Kuwala kwa Kuwala Kolakwika ndi Zoopsa Zomwe Zingakhalepo Pamene chizindikiro cha sensa chikupitirira malire, kuwala kwa injini (MIL) pa dashboard kudzawala. Pogwiritsa ntchito chida chowunikira cha OBD, ma code monga P0105 (kulephera kwa sensa) ndi P0106 (chizindikiro chosamveka) nthawi zambiri amatha kuwerengedwa. Pafupifupi 60% ya zolakwikazo zimachitika chifukwa cha kuwonongeka kwa sensa, ndipo 40% zimachitika chifukwa cha mavuto a mawaya. Kunyalanyaza zizindikirozi kungayambitse zolakwika zazing'ono zomwe zimakhala mavuto akuluakulu, ndipo nthawi zina, galimotoyo imatha kuyima mwadzidzidzi ikuyendetsa, makamaka panthawi yochepetsa mphamvu ya galimoto kapena kusintha giya, zomwe zimabweretsa zoopsa zazikulu zachitetezo^.
Cholakwika Chotsatira: "Kumenyedwa" Komwe Kumachitika Chifukwa cha Zinthu Zambiri
Kulephera kwa sensa ya kuthamanga kwa madzi m'thupi sikumachitika chifukwa cha chinthu chimodzi koma kumachitika chifukwa cha mavuto ambiri monga sensa yokha, mawaya, ndi mapayipi a vacuum.
Kusweka kwa dera lamkati kapena dera lalifupi mu sensa kudzaletsa chizindikiro cha kuthamanga kuti chisasinthidwe ndikutumizidwa mwachizolowezi, monga kudula kwa njira mu siteshoni yotumizira chidziwitso, ndipo ECU sidzalandira deta yolondola^.
Zizindikiro zotulutsa zosazolowereka nazonso ndi zolakwika zofala. Nthawi zambiri, chizindikirocho chiyenera kusintha mofatsa ndi vacuum ya intake manifold, ndipo ngati chizindikirocho "chachedwa", ECU idzasintha jakisoni wamafuta kutengera chidziwitso cholakwika, zomwe zimapangitsa kuti ntchito ya injini ikhale yosazolowereka^. Kuphatikiza apo, ngati payipi ya vacuum yolumikiza sensor ya intake pressure ku chitoliro cha intake yatsekeka kapena kutayikira, idzaletsa sensoryo kumva chizindikiro cholondola cha kuthamanga, monga momwe "mlatho" umaswekera ndikusokoneza kutumiza kwa chidziwitso.
Kuzindikira Molondola: Kubwezeretsa Masomphenya a Sensor
Pothana ndi vuto la sensa ya kuthamanga kwa madzi, njira zotsatirazi zitha kutengedwa kuti muthetse mavuto molondola: Choyamba, gwiritsani ntchito chida chodziwira vuto kuti muwerenge khodi yolakwika ndikuyamba kudziwa komwe vuto likupita. Ngati khodi yolakwika yokhudzana ndi sensa yawonetsedwa, yang'anani ngati payipi ya vacuum yatsekeka kapena ikutuluka, komanso ngati mawaya awonongeka kapena ali ndi kukhudzana koyipa. Kachiwiri, yesani kuyesa magwiridwe antchito pa sensa, tsegulani pulagi ya sensa, yatsani switch yoyatsira, ndikuyesa voltage pakati pa VCC terminal ndi E2 terminal pa pulagi. Nthawi zambiri, iyenera kukhala pakati pa 4.5 ndi 5.5V. Ngati voltage si yachilendo, yang'anani mawaya kuchokera ku ECU kupita ku sensa kapena ECU yokha. Pomaliza, gwiritsani ntchito njira yosinthira. Sinthani sensa yolakwika yomwe ikuganiziridwa kuti ndi yolakwika ndi yachibadwa. Ngati cholakwikacho chatha, zitha kutsimikiziridwa kuti sensayo yawonongeka.
Ngakhale kuti sensa yoyezera kuthamanga kwa injini ndi yaying'ono, ndiyofunikira kwambiri kuti injini igwire bwino ntchito. Kumvetsetsa ntchito yake, zizindikiro za vuto, ndi njira zodziwira matenda kungathandize eni magalimoto kuzindikira mavuto pakapita nthawi, kupewa zolakwika zazing'ono zomwe zimayambitsa kutayika kwakukulu ndikusunga injiniyo bwino nthawi zonse.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
