Izizathu ezi-4 eziyinhloko zokuthi kungani i-tachometer ibalulekile ekusebenzeni kwemoto

Imvamisa ibonakala ezimotweni ezithuthwayo kuphela, i-tachometer ibalulekile ekuqoqweni kwedatha, ukushintsha amagiya, ukonga uphethiloli, nempilo yenjini.

Izimoto zesimanje, amaloli kanye nama-SUV ancika kakhulu kwezobuchwepheshe minyaka yonke. Kusukela kumasistimu okuphepha asizwa umshayeli kuya kusofthiwe ethuthukisiwe yokuqapha nokulungiswa kwesistimu kaphethiloli, umshayeli wansuku zonke wanamuhla wehluke kakhulu kunawakudala. Enye yezinto ezisele (imvamisa ezimotweni ezinegiya elishintshwayo) yi-tachometer. Eminyakeni edlule, "i-tachometer" yayisetshenziswa umshayeli ukuze anqume isikhathi esingcono kakhulu nesisebenza kahle kakhulu sokusuka egiyeni eliphansi ukuya kwephezulu. Namuhla, i-tachometer ebonakalayo ayibalulekile njengoba yayinjalo eminyakeni edlule, kodwa isebenza ngenjongo.

Ukuqonda inhloso yangempela ye-tachometer

Ngokuphambene nenkolelo evamile, i-tachometer ingaphezu nje kwegeji ebonisa isivinini senjini. Eqinisweni, i-tachometer iqukethe uhlelo lwemishini yokulawula eqoqa idatha, idlulisela ku-ECU (iyunithi yokulawula injini) futhi ithinta ukusebenza kwezinhlelo eziningana ezizimele. Ngokusemthethweni, i-tachometer iyithuluzi elikala ukujikeleza kwe-crankshaft yenjini, enesibopho sokuzungezisa induku ngayinye yokuxhuma nepiston emjikelezweni womlilo. Uma i-crankshaft izungeza amadigri angu-360, iqeda ukuguquguquka okuphelele. Isivinini esiphelele sokujikeleza kwe-crankshaft silinganiswa ngama-revolution ngomzuzu noma i-rpm.

I-RPM iboniswa kugeji, ngokuvamile etholakala kudeshibhodi yomshayeli futhi, ezimweni eziningi, ngakwesokunxele. Ivamise ukukhombisa uchungechunge lwezinombolo ukusuka kuziro kuye ku-8 noma 9 ezinemigqa eminingana phakathi kwenombolo ngayinye kusibonisi se-analog noma sedijithali. Inombolo ephakathi kuka-0 no-9 empeleni ichazwa ngokuthi izikhathi eziyi-1,000 zalelo nani. Amadijithi okugcina aboniswa ku-tachometer ngokuvamile agqanyiswa ngokubomvu. Uma injini ishesha, umcibisholo uzokhomba inombolo elingana ne-rpm yenjini. Uma umcibisholo ukhomba uphawu olubomvu, kuthathwa ngokuthi "umugqa obomvu" noma usebenza ngaphezu komkhawulo onconywayo.

Ukwazi umsebenzi tachometer, ake sibheke 4 izizathu eziyinhloko ukuthi kungani kubalulekile ukusebenza imoto.

1. Ithwebula futhi idlulise idatha ukusiza ukushintsha imoto yakho

Uma unomshini ozishintshayo futhi une-tachometer, uzoqaphela ukufana okuthile uma usuka egiyeni eliphansi uye egiyeni eliphezulu. I-transmission ihlelelwe ukuthi inyuke ngesivinini esinikeziwe. I-RPM ikalwa nge-tachometer bese idluliselwa ku-TCM (Transmission Control Module) noma i-ECU. Ama-revolution afanayo aboniswa kugeji. Nakuba isikali ngokwaso singesezinjongo zokubonisa kuphela, sivumela umshayeli ukuthi azi ukuthi alindele nini ukushintsha.

2. Yazisa abashayeli bokuhambisa ngesandla ukuthi bagudluke nini

I-tachometer sensor isiza nomshayeli ukuthi azi ukuthi ulishintsha nini igiya ngalinye uma esebenzisa i-manual transmission. Izimoto eziningi, amaloli, nama-SUV ashintshwayo kufanele asuke phansi aye phezulu lapho i-tachometer ifunda phakathi kuka-3,000 no-4,000 wenjini rpm. Abashayeli bavame ukufundiswa ukushintsha injini ngokusekelwe kumsindo kanye nezimo zokushayela esikhundleni sokuhlehliswa kwe-tachometer, kodwa i-tachometer yenza umsebenzi obalulekile ngokunikeza inkomba ebonakalayo.

3. Isiza Ekuthuthukiseni Ukonga Kwamafutha

I-tachometer esebenzayo ingasiza nalabo abanama-manual transmission bathuthukise ukonga kukaphethiloli. Iningi labakhiqizi bezimoto liyacacisa ebhukwini lomnikazi wemoto ukuthi iyiphi i-RPM okufanele ishintshwe injini ukuze isebenze kahle. Ukuze kuzuzwe ukusebenza kahle okukhulu, injini yesimanje yangaphakathi evuthayo ihlanganiswa nohlobo oluthile lokudluliswa noma ukudluliswa kanye nesilinganiso se-axle yokushayela. Inhlanganisela yawo womathathu amasistimu ahlukene yaziwa njengesitimela esinamandla. Ukushintsha okunconywe ngumkhiqizi kusiza ukudlulisa amandla emasondweni ngokuhudula okuncane. Ngokuncishiswa "komthwalo" noma "ukudonsa" enjinini, uphethiloli omncane uyashiswa, okuholela ekongeni kukaphethiloli okungcono.

4. Yandisa impilo yenjini.

Injini evuthayo yangaphakathi iqukethe izingxenye ezimbalwa ezihambayo ezidinga ukugcotshwa ukuze zisebenze. Njengoba ingxenye ngayinye ihamba, ukungqubuzana kwakhiwa ngokuphenduka ngakunye kwenjini, bese kuba nokushisa. Lapho injini ijikeleza ngokushesha (noma i-RPM ephezulu), ukushisa okungeziwe kuzokhiqizwa. Uma lokhu kwenzeka, izingxenye zensimbi ezixhumene nazo zigcina zishisa zize ziqale ukulahlekelwa ukuthambisa, okungaholela ekuhlulekeni okuyinhlekelele. Uma i-tachometer kanye nezingxenye ezihambisanayo zisebenza kahle, ukudluliselwa kungashintsha ngesikhathi, noma izishayeli zokuhambisa ngesandla zingashintsha njengoba kunconyiwe, andise impilo yenjini.

I-tachometer idlala indima ebalulekile enjinini yesimanje njengoba ihamba kakhulu kunenaliti ehambayo kugeji. Uma uqaphela ukuthi inzwa ye-tachometer ayisebenzi, kungase kube uphawu lwenkinga encane, njengenzwa ephukile noma intambo exekethile, noma inkinga enamandla amakhulu, njengenzwa yesikhathi esonakele. Uma usola ukuthi i-tachometer ayisebenzi emotweni yakho, thinta umakhenikha ochwepheshe futhi ubatshele ukuthi bahlole imbangela yenkinga ukuze kulungiswe kahle.
