Kungani izimoto zesimanje zidinga tachometer?
Akudingekile ukuthi umshayeli wesimanje abe nolwazi olunzulu ngesakhiwo semoto ukuze ayishayele ngokuphepha nsuku zonke eya noma ebuya emsebenzini. Vumelana, esikhathini sethu kukhona abanikazi bezimoto abaningi abanokuhlangenwe nakho okuthakazelisayo kokushayela abangakakwazi impendulo ecacile yombuzo wokukhuluma: kungani i-tachometer ifakwe kuphaneli yezinsimbi?
Ngisho noma, ngokushesha noma kamuva, ubheka ku-intanethi futhi ubambe ngekhanda inkulumo yesakramente: "I-tachometer iyithuluzi elikala isivinini se-crankshaft yemoto ngomzuzu owodwa," akubona bonke abashayeli abazoqonda ukuthi kungani kufanele alandele lokhu. Phela, kwabaningi, into eyinhloko ukuthi isondo lokuqondisa namasondo liyajikeleza.
Ngakolunye uhlangothi, uma abakhiqizi bezimoto besebenzisa imali ukuze bafake lolu cingo kuzo zonke izimoto ze-serial, khona-ke bayaqiniseka ukuthi "i-helmsman" iyayidinga. Kodwa-ke, empeleni, ukufundwa kwe-tachometer kulawulwa kuphela abashayeli abathuthukile, okuthi, njengomthetho, bashayele izimoto nge-gearbox manual noma basebenzise imodi "okuzenzakalelayo".
Abathandi bokushayela abanjalo banethuba lokuzungeza injini ifike ngesivinini esiphezulu ukuze kuthuthukiswe amandla. Kodwa akusiyo imfihlo ukuthi ukushayela njalo kule modi kunciphisa kakhulu ukuphila injini evuthayo yangaphakathi. Njengokunyakaza okuhlelekile ngesivinini esiphansi, akunawo umthelela omuhle kakhulu empilweni yakhe. Ngakho-ke, kuyinto efiselekayo kumshayeli ngamunye ukulawula le nkomba, okuwumsebenzi oyinhloko we-tachometer.
Kulabo ababalulekile ukuqinisekisa ukusebenza okuphephile kwemoto, ukushayela imoto kufanele kulandele imodi yejubane elilungile, ukugcina umcibisholo ungaphakathi kwemingcele eyamukelekayo. Lokhu ngeke nje kwandise isisetshenziswa senjini, kodwa kuzophinde konge amalitha engeziwe kaphethiloli.
Ngemoto ngayinye, indawo efanelekile lapho umcibisholo wedivayisi "ihamba" ngemodi ephephile ingase ihluke kuye ngohlobo lweyunithi yamandla nezici zayo. Kodwa ngokuvamile iphakathi kuka-2000 no-3000 rpm.
Ezimotweni ezine-"mechanics" kanye nemodi ye-manual "automatic", isivinini sokudayela kwe-tachometer silawulwa ngokushintshwa kwegiya. Uma kukhona i-automatic transmission, lokhu kwenziwa ngokushintsha i-gas pedal. Ngaphezu kwalokho, i-tachometer ingasetshenziswa ukuxilonga injini enephutha ngaphandle kokushiya imoto. Uma ngokungenzi lutho ijubane "lintanta" futhi umcibisholo uzulazula ngokungagunyaziwe eduze nokudayela, khona-ke kumshayeli onolwazi lokhu kuzoba isignali eqinisekisayo ukuthi sekuyisikhathi sokuvakashela isevisi yemoto.
Nokho, ngokuqinisekile, abanikazi abaningi bezimoto ungakhathazeki nhlobo ngalesi sihloko futhi ungalokothi ubheke tachometer, bethemba ngokuphelele ukudluliswa okuzenzakalelayo. Ngakho ekugcineni kulungile ukuvuma ukuthi le divayisi ifakwe ezimotweni hhayi abashayeli, kodwa namanje isetshenziselwa oomakhenikha bezimoto abayisebenzisayo ngesikhathi sokuxilongwa kwenjini.
