Sei motokari dzemazuva ano dzichida tachometer?
Hazvidikanwi kuti mutyairi wemazuva ano ave neruzivo rwakakwana rwechimiro chemotokari kuitira kuti aityaire zvakachengeteka zuva nezuva kuenda nekudzoka kubasa. Bvumiranai, munguva yedu kune varidzi vakawanda vemotokari vane ruzivo rwekutyaira runoshamisa avo vasati vaziva mhinduro yakajeka kumubvunzo wekutaura: sei tachometer yakaiswa pane chimbo chezviridzwa?
Kunyange kana, nokukurumidza kana kuti gare gare, ukatarisa paInternet uye wobata nomusoro mutsara wesakaramende: “Tachometer mudziyo unoyera kumhanya kwecrankshaft yemotokari muminiti imwe,” haasi mutyairi wose achanzwisisa kuti nei iye pachake achifanira kutevera izvi. Mushure mezvose, kune vakawanda, chinhu chikuru ndechokuti chidhiraivho uye mavhiri anotenderera.
Kune rumwe rutivi, kana automakers vakashandisa mari kuisa chigadzirwa ichi mumotokari imwe neimwe, saka vane chokwadi chokuti "helmsman" inoida. Asi, nhamo, chaizvoizvo, kuverenga tachometer kunonyanya kudzorwa chete nevatyairi vepamusoro, avo, sekutonga, vanotyaira motokari nebhokisi regiya rekushandisa kana kushandisa bhuku re "otomatiki" mode.
Vanotyaira vakadai vane mukana wekutenderedza injini kusvika pakumhanya kwepamusoro kuvandudza masimba. Asi hachisi chakavanzika kuti kugara uchityaira mune iyi modhi kunoderedza zvakanyanya hupenyu hweinjini yekupisa. Kungofanana nekufamba kwakarongeka pakumhanya kwakaderera, haina mhedzisiro yakanaka pahutano hwake. Nokudaro, zvinodikanwa kuti mutyairi mumwe nomumwe adzore chiratidzo ichi, iro ndiro basa guru re tachometer.
Kune avo vakakosha kuve nechokwadi chekushanda kwakachengeteka kwemota, kutyaira mota kunofanirwa kutevedzera yakanyanya kumhanya modhi, kuchengetedza museve mukati memiganhu inogamuchirwa. Izvi hazvizongowedzera injini sosi, asiwo chengetedza mamwe marita emafuta.
Pamotokari imwe neimwe, iyo yakakwana nzvimbo iyo museve wemudziyo "unofamba" mune yakachengeteka modhi inogona kunge yakasiyana zvichienderana nerudzi rwesimba remagetsi uye maitiro ayo. Asi kazhinji iri pakati pe2000 ne3000 rpm.
Mumotokari dzine "mechanics" uye ine bhuku re "otomatiki" modhi, kumhanya kweiyo tachometer dial inodzorwa nekuchinja kwegiya. Pamberi peiyo otomatiki kutapurirana, izvi zvinoitwa nekushandisa gasi pedal. Mukuwedzera, tachometer inogona kushandiswa kuongorora injini isina kunaka pasina kusiya motokari. Kana pasina basa kumhanya "kunoyangarara" uye museve uchidzungaira zvisina mvumo uchitenderedza dial, saka kumutyairi ane ruzivo ichi chichava chiratidzo chinogutsa chekuti inguva yekushanyira sevhisi yemotokari.
Zvisinei, chokwadi, vazhinji varidzi vemotokari havanetseki pamusoro peiyi nyaya zvachose uye havambotarisiri tachometer, vachivimba zvachose neotomatiki hutachiwana. Saka pakupedzisira zvakanaka kubvuma kuti chigadzirwa ichi chakaiswa mumotokari kwete yevatyairi, asi zvakadaro kune auto mechanics vanoishandisa panguva yekuongorora injini.
