Imoto tachometer - iyini futhi yenzelwe ini

I-tachometer yemoto

Eceleni kwesivinini esisheshayo kudeshibhodi yazo zonke izimoto zesimanje kune-tachometer. Abanye abantu bakholelwa ngephutha ukuthi le divayisi ayinamsebenzi kumshayeli ojwayelekile. Eqinisweni, i-tachometer idlala indima ebalulekile ekusebenzeni kahle kwenjini.

Isebenza kanjani le divayisi, injani, i-tachometer ihlobene kanjani nokusebenza kahle kwemoto nokuthi ungayifaka kanjani kahle? Okuningi kulokhu ngokuqhubekayo kusibuyekezo sethu.

Yini i-tachometer yemoto

I-tachometer yidivayisi exhunywe kuyo injini crankshaft, ukukala imvamisa yokujikeleza kwayo. Kubukeka njengegeji elinomcibisholo nesikali. Esikhathini esiningi, imisebenzi yale divayisi isetshenziswa abashayeli abathanda ukushayela ngokushesha. Ekudlulisweni mathupha noma nge-othomathikhi kwimodi yezandla, kungenzeka "ukuyiphenduphendula" injini ngejubane eliphezulu ukuze uthole amandla okuhamba phambili lapho ushintsha amagiya.

Nazi ezinye izizathu zokuthi kungani i-tachometer idingeka kuyo yonke imoto.

1. Ukusebenza kwenjini yomlilo yangaphakathi ngejubane elincishisiwe (kufika ku-2000 rpm) kunciphisa kakhulu ukusetshenziswa kukaphethiloli, kepha lokhu kuzodala izinkinga ezihlobene. Isibonelo, lapho unyakaza, imoto ingaphansi komthwalo osindayo. Inhlanganisela kaphethiloli ekamelweni lomlilo isatshalaliswa ngokungalingani, lapho isha khona kabi. Ngenxa yalokho - ukwakheka komsizi kumasilinda, ama-spark plugs nama-piston. Ngesivinini esincishisiwe, ipompo likawoyela lidala ingcindezi enganele yokugcoba injini, okuvela kuyo indlala kawoyela, futhi imihlangano yecrankshaft iphela ngokushesha.
2. Ukusebenza okuqhubekayo kwenjini ngesivinini esikhuphukile (ngaphezu kuka-4000) akugcini ngokuholela ekusetshenzisweni ngokweqile kwephethiloli, kodwa futhi kunciphisa kakhulu imithombo yayo. Kule modi, injini yangaphakathi yomlilo iyashisa, uwoyela ulahlekelwa yizakhiwo zawo, futhi izingxenye zihluleka ngokushesha. Ungayinquma kanjani inkomba efanelekile lapho "ungayiguqula" khona imoto?

Kuze kube manje, abakhiqizi bafaka i-tachometer ezimotweni. Isibonisi ebangeni elisuka ku-1/3 kuye ku-3/4 ekuguqulweni lapho imoto ihambisa khona amandla amakhulu kubhekwa njengelungile kumoto (le nkomba iboniswe kumadokhumenti obuchwepheshe womshini).

Lesi sikhawu sihlukile emotweni ngayinye, ngakho-ke umshayeli kufanele aqondiswe hhayi kuphela ngokuhlangenwe nakho kwabanikazi be- "combat classics", kepha nezincomo zomkhiqizi. Ukunquma leli nani, isikali se-tachometer sehlukaniswe saba yizindawo eziningana - okuluhlaza okotshani, okuphuzi (kwesinye isikhathi kuba igebe elingenambala phakathi kokuluhlaza nokubomvu) nokubomvu.

Indawo eluhlaza yesikali se-tachometer ikhombisa imodi yezomnotho yemoto. Kulokhu, imoto izoba nemikhakha emibi. Lapho inaliti idlulela endaweni elandelayo (imvamisa ingaphezulu kwe-3500 rpm), injini isebenzisa uphethiloli omningi, kepha ngasikhathi sinye iba namandla amakhulu. Kuyadingeka ukusheshisa kulezi zivinini, ngokwesibonelo, ngesikhathi sokudlula.

Ebusika, i-tachometer nayo ibalulekile, ikakhulukazi ngesikhathi sokufudumeza injini efakwe i-carburetor. Kulokhu, umshayeli ulungisa inani lezinguquko nge-lever "choke". Kuyingozi ukufudumeza injini ngejubane elikhulu, ngoba okukhiphayo kushisa lokusebenza kufanele kwenziwe kahle (funda ngokushisa kwenjini esihlokweni esehlukile). Kunzima kakhulu ukucacisa le nkomba ngomsindo wenjini. Lokhu kudinga i-tachometer.

Izimoto zesimanje zilawula ukwanda / ukwehla kwama-revs ngokwazo enqubweni yokulungiselela injini ohambweni. Ezimotweni ezinjalo, le divayisi izosiza umshayeli ukuthola isikhathi sokushintsha kwejubane.

Ngemininingwane yokuthi ungagxila kanjani ezinkomba ze-tachometer ngenkathi ushayela, bona ividiyo:

Ukuhamba nge-tachometer ne-speedometer

Kungani udinga i-tachometer

Ukuba khona kwale divayisi akuphazamisi ukusebenza kwemoto noma izinhlelo zayo ngandlela thile. Esikhundleni salokho, kuyinto evumela umshayeli ukuthi alawule ukusebenza kwenjini. Ezimotweni ezindala, isivinini senjini singatholakala ngomsindo.

Ubuningi bezimoto zesimanje banomsindo omuhle kakhulu wedwa, ngenxa yokuthi nomsindo wenjini awuzwakali kahle. Njengoba ukusebenza njalo kwenjini ngejubane eliphezulu kugcwele ukwehluleka kweyunithi, le pharamitha kufanele ihlolwe. Esinye sezimo lapho idivayisi ezoba wusizo khona ukuthola isikhathi sokushintsha igiya lokuya phezulu noma phansi lapho usheshisa imoto.

Ngenxa yalesi sizathu, ideshibhodi ifakwe i-tachometer, eyenzelwe imoto ethile. Le divayisi ingakhombisa inani elilungile lezinguquko zale yunithi, kanye nomugqa obizwa ngokuthi obomvu. Ukusebenza kwesikhathi eside kwenjini yomlilo yangaphakathi akuthandeki kulo mkhakha. Njengoba injini ngayinye inemikhawulo yayo yesivinini esiphezulu, i-tachometer kufanele ifaniswe nemingcele yeyunithi yamandla.

Isimiso sokusebenza kwedivayisi

AmaTachometer asebenza ngohlelo olulandelayo.

• Uhlelo lokushisa olwenziwe luqala injini... Inhlanganisela kaphethiloli womoya egumbini lomlilo iyasha, eqhuba izinduku zokuxhuma zeqembu le-piston. Baphendukisa i-crankshaft yenjini. Ngokuya ngemodeli yedivayisi, inzwa yayo ifakwe ku-motor unit oyifunayo.
• Inzwa ifunda inkomba yejubane le-crankshaft. Ngemuva kwalokho ikhiqiza ukudonsa kwemithambo bese ibathumela kwiyunithi yokulawula idivayisi. Lapho, lesi siginali sisebenzisa i-arrow drive (siyishukumisela esikalini), noma sinikeze inani ledijithali eliboniswa esikrinini esihambisanayo sedeshibhodi.

Isimiso esiqondile sokusebenza kwedivayisi sincike ekuguqulweni kwayo. Kunezinhlobonhlobo zamadivayisi anjalo. Zihlukile komunye nomunye hhayi ngaphandle kuphela, kepha futhi nasendleleni yokuxhuma, kanye nangendlela yokucubungula idatha.

Idizayini ye-Tachometer

Onke ama-tachometer ahlukaniswe ngokwejwayelekile ngezigaba ezintathu.

1. Imishini. Lokhu kuguqulwa kusetshenziswa ezimotweni ezindala nasezithuthuthu. Ingxenye eyinhloko kulokhu ikhebula. Ngakolunye uhlangothi, ixhuma ku-camshaft (noma i-crankshaft). Omunye umkhawulo ulungiswe ngendlela yokwamukela etholakala ngemuva kwesikali sedivayisi.

Ngesikhathi sokujikeleza kwe-shaft, umnyombo ophakathi ujika ngaphakathi kukasayizi. I-torque idluliselwa emagiyeni lapho kuxhunywe khona umcibisholo, okuyimisa kahle. Ngokuvamile, amadivayisi anjalo afakwe kuma-motor anejubane eliphansi, ngakho-ke isikali esikuwo sihlukaniswe saba izingxenye ezinenani lama-250 rpm. konke.

2. I-Analog. Banemishini engaphezu kweminyaka engama-20 ubudala. Izinketho ezithuthukisiwe zifakiwe ezimotweni zesabelomali sanamuhla. Ngokubukeka, lokhu kuguqulwa kufana kakhulu nokwedlule. Inesikali esiyisiyingi esinomcibisholo ohamba ngaso.

Umehluko omkhulu phakathi kwe-tachometer ye-analog netachometer ewumshini kusendleleni yokudlulisela inkomba yejubane. Amadivayisi anjalo aqukethe ama-node amane.

• Inzwa. Ixhuma ku-crankshaft noma ku-camshaft ukuze ifunde i-rpm.
• Ikhoyili kazibuthe. Ifakwe ezindlini ze-tachometer. Kutholwa isignali evela enzwa, eguqulwa ibe amandla kazibuthe. Cishe zonke izinzwa ze-analog zisebenza ngokuya ngalesi simiso.
• Imicibisholo. Ifakwe uzibuthe omncane ophendula amandla enkambu akhiqizwe kwekhoyili. Ngenxa yalokhu, umcibisholo udluliselwe ezingeni elifanele.
• Izikali. Izigaba kuso ziyefana nasendleleni ye-analogue yemishini (kwezinye izimo ingu-200 noma i-100 rpm).

Amamodeli wedivayisi anjalo angajwayelekile futhi akude. Esimweni sokuqala, zifakwe kudeshibhodi eduze kwe-speedometer. Ukuguqulwa kwesibili kungafakwa kunoma iyiphi indawo efanelekile kudeshibhodi. Ngokuyinhloko, lesi sigaba samadivayisi sisetshenziswa uma umshini ungenayo into enjalo evela efektri.

3. Ezobuchwepheshe. Lolu hlobo lwedivayisi lubhekwa njengolunembile kakhulu. Ziqukethe inani elikhudlwana lezinto ngokuqhathaniswa nezinketho zangaphambilini.

• Inzwa efunda ukuzungeza komphako efakwe kuwo. Ikhiqiza ama-pulses adluliselwa ku-node elandelayo.
• Iprosesa icubungula idatha futhi idlulisele isiginali ku-optocoupler.
• I-optocoupler iguqula imizwa kagesi ibe amasiginali akhanyayo.
• Khombisa. Ibonisa inkomba engaqondwa ngumshayeli. Idatha ingakhonjiswa ngesimo sezinombolo noma ngesimo sesikali esiphothuliwe ngomcibisholo.

Imvamisa ezimotweni zesimanje, i-tachometer yedijithali ixhunywe kuyunithi yokulawula ngogesi yemoto. Ukuvimbela ifoni ukuthi ingadli amandla ebhethri lapho ukuthungela kuvaliwe, iyacima ngokuzenzakalela.

Izinhlobo nezinhlobo zama-tachometers

Kunezinhlobo ezintathu zama-tachometers esewonke:

• Uhlobo lwemishini;
• Uhlobo lwe-Analog;
• Uhlobo lwedijithali.

Kodwa-ke, noma ngabe hlobo luni, ama-tachometer angalingana futhi abe kude ngokuya ngendlela yokufaka. I-elementi elungisa ijubane le-crankshaft ifakwa ikakhulu endaweni yayo eseduze, okungukuthi, eduze ne-flywheel. Imvamisa oxhumana naye uxhunywe kwikhoyili yokushisa noma koxhumana naye we-crankshaft sensor.

Imishini

Ukuguqulwa kokuqala kwama-tachometers kwakungumshini nje. Idivayisi yayo ifaka ikhebula lokushayela. Umkhawulo owodwa nesilayida uxhuma ku-camshaft noma ku-crankshaft, kuthi omunye uye ku-gearbox we-tachometer.

I-torque idluliselwa ku-gearbox, eqhuba amandla kazibuthe. Lokho, nakho, kwehlisa inaliti ye-tachometer ngenani elidingekayo. Lolu hlobo lwedivayisi lunephutha elikhulu (kufika ku-500 rpm). Lokhu kungenxa yokuthi ikhebula liyajika ngenkathi kudluliswa amandla, okuhlanekezela amanani wangempela.

I-Analog

Imodeli ethuthuke kakhulu yi-tachometer ye-analog. Ngaphandle, kufana kakhulu nokuguqulwa kwangaphambilini, kepha kwehlukile kumgomo wokudlulisa inani le-torque kudrayivu yomcibisholo.

Ingxenye ye-elektroniki yedivayisi ixhunywe kwinzwa yesikhundla se-crankshaft. Kukhona ikhoyili kazibuthe ngaphakathi kwe-tachometer ephambukisa inaliti ngenani elidingekayo. Ama-tachometers anjalo nawo anephutha elikhulu (kufika ku-500 rpm).

I-Digital

Ukuguqulwa kwakamuva kakhulu kwama-tachometers kungu-digital. Ama-Turnovers angaboniswa njengezinombolo ezikhanyayo. Kumamodeli athuthuke kakhulu, ukudayela okubonakalayo ngomcibisholo kuyaboniswa esikrinini.

Idivayisi enjalo ixhunywe nenzwa ye-crankshaft. Esikhundleni sekhoyili kazibuthe kuphela, i-microprocessor ifakwa kuyunithi ye-tachometer, ebona amasiginali avela kunzwa futhi ikhiphe inani elihambisanayo. Iphutha lamadivayisi anjalo lincane kakhulu - cishe ama-revolution angu-100 ngomzuzu.

Isungulwe

Lawa ngama-tachometers afakwe emotweni asefektri. Umenzi ukhetha ukuguqulwa okuzokhombisa amanani we-rpm ngokunembile ngangokunokwenzeka futhi akhombise imingcele ephezulu evunyelwe emotweni enikeziwe.

Lawa ma-tachometer yiwona anzima kakhulu ukuwalungisa nokuwafaka esikhundleni ngoba afakwe kudeshibhodi. Ukucisha nokufaka idivaysi entsha, kuyadingeka ukuthi uhlukanise yonke ideshibhodi, futhi kwesinye isikhathi nedeshibhodi (kuya ngemodeli yemoto).

Ukude

Kulula kakhulu ngama-tachometer akude. Afakwe noma ikuphi kukhonsoli yezimoto, noma kuphi lapho umshayeli efisa khona. Amadivayisi anjalo asetshenziswa emishinini lapho i-tachometer inganikezwa kusuka efektri.

Ngokuvamile, amadivayisi anjalo adijithali noma okungenani i-analog, ngoba indawo akuyo ayincikile ebude bekhebula. Ngokuyinhloko, ama-tachometers anjalo afakwe eduze kwedeshibhodi. Lokhu kuvumela umshayeli ukuthi akwazi ukulawula isivinini senjini ngaphandle kokuphazamiseka emgwaqweni.

Indlela yokusebenzisa ulwazi lwe-tachometer?

Ukufundwa kwe-tachometer kusiza umshayeli ukuthi azulazule ezimeni ezahlukene. Okokuqala, le divayisi isiza ukuletha iyunithi yamandla ngesivinini esibucayi. Isivinini esiphezulu sivunyelwe kuphela esimweni esiphuthumayo. Uma usebenza njalo injini kule modi, izohluleka ngenxa yokushisa ngokweqile.

I-tachometer inquma ukuthi yiliphi iphuzu lapho kungenzeka ukushintshela ejubaneni elikhulayo. Abashayeli abanolwazi baphinde basebenzise i-tachometer ukuze bashintshele egiyeni eliphansi (uma uvula i-neutral bese uvula igiya eliphansi uma ungenzi lutho, imoto izoluma ngenxa yejubane lokujikeleza kwamasondo okushayela ngaphansi kwalawo ayewazungeza ngaphambili).

Uma ugxila kahle ekufundweni kwe-tachometer, unganciphisa ukusetshenziswa kukaphethiloli (imodi yezemidlalo enesivinini esivamile sisebenzisa uphethiloli owengeziwe). Ukushintsha amagiya ngesikhathi futhi kukuvumela ukuthi ukhulise impilo yokusebenza yezingxenye zeqembu le-cylinder-piston noma ukhethe imodi yokushayela efanele.

Ama-tachometers avela kumamodeli emoto ahlukene awashintsheki, ngoba lezi zakhi zenzelwe izinhlobo ezithile zezinjini nezimoto.

I-tachometer ixhunywe kanjani nezinzwa ezizenzakalelayo

Lapho uthenga i-tachometer entsha, umshayeli angabona ukuthi ayikho inzwa ehlukile kukhithi. Eqinisweni, le divayisi ayinayo inzwa ngayinye, efakwe kushaft yemoto. Asikho nje isidingo saso. Kwanele ukuxhuma izintambo kwenye yezinzwa ezilandelayo.

• Inzwa ye-Crankshaft. Ilungisa isikhundla sezikhonkwane kusilinda sokuqala senjini futhi inikeze umfutho kagesi. Lesi siginali siya kwikhoyili kazibuthe noma kwiprosesa (kuya ngohlobo lwedivayisi). Lapho, umfutho uguqulwa ube yinani elifanele bese uboniswa esikalini noma ngokudayela.

• Idling sensor (i-valve XX ilungile). Ezinjini zomjovo, inesibopho sokunikeza umoya ezinhlwini zokungenisa eziningi, ngokudlula i-valve mpintsha. Ezinjini ze-carburetor, lo mlawuli ulawula ukunikezwa kukaphethiloli esiteshini esingenzi lutho (lapho unyathela amabhuleki enjini, kuvimbela ukuhamba kukaphethiloli, okuholela emnothweni wephethiloli). Ngophethiloli olawulwa yi-valve, nesivinini senjini naso siyanqunywa.

• ECU. Ama-tachometer anamuhla axhunywe kuyunithi yokulawula ngogesi, ethola amasiginali kuzo zonke izinzwa ezixhunywe enjinini. Lapho kungena idatha eningi, izilinganiso zizoba ezinembe kakhudlwana. Kulokhu, inkomba izothunyelwa ngephutha elincane.

Ukungasebenzi kahle okukhulu

Lapho inaliti ye-tachometer ingachezuki phakathi nokusebenza kwenjini (futhi kumamodeli amaningi emoto amadala le divayisi ayinikeziwe nhlobo), umshayeli kuzodingeka anqume isivinini ngomsindo wenjini evuthayo yangaphakathi.

Isibonakaliso sokuqala sokungasebenzi kahle ekusebenzeni kwe-tachometer yomshini (i-analogue) ukwephulwa kokuhamba kahle komcibisholo. Uma igxuma, igxuma noma igxuma / iwa kakhulu, udinga ukuxilonga ukuthi kungani i-tachometer iziphatha ngale ndlela.

Nakhu okudingeka ukwenze uma ukusebenza okungalungile kwe-tachometer kutholwa:

Ngakho-ke, i-tachometer izosiza umshayeli ukuthi asebenzise kahle injini yemoto yakhe. Izinkomba ze-RPM zenza sikwazi ukunquma isikhathi sokushintshwa kwamagiya nokulawula ukusetshenziswa kukaphethiloli ngendlela ejwayelekile yokushayela.

Ividiyo ngesihloko

Nansi ividiyo emfushane yokuthi ungaxhuma kanjani i-tachometer yangaphandle:

I-Aliexpress. I-tachometer yesilawuli kude + uxhumano

Imibuzo nezimpendulo:

Uyini umehluko phakathi kwe-tachometer ne-speedometer? Amadivayisi asebenza ngesimiso esifanayo. I-tachometer kuphela ekhombisa ijubane lokujikeleza kwe-crankshaft, kanti i-speedometer ikhombisa amasondo angaphambili emotweni.

Ilinganisa kanjani i-tachometer emotweni? Isikali se-tachometer sihlukaniswe imikhakha ekhombisa isivinini senjini. Ukuze kube lula ukulinganisa, ukuhlukaniswa kuhambisana nokuphenduka okuyinkulungwane ngomzuzu.

Mangaki ama-revolutions okufanele abe khona ku-tachometer? Uma ungenzi lutho, le parameter kufanele ibe esifundeni sika-800-900 rpm. Ngokuqala okubandayo, i-rpm izoba ku-1500 rpm. Njengoba injini evuthayo yangaphakathi ifudumala, zizokwehla.
