Chifukwa chiyani magalimoto amakono amafunikira tachometer?
Sikoyenera kuti dalaivala wamakono adziwe bwino za kapangidwe ka galimoto kuti ayendetse bwino tsiku lililonse popita ndi pobwera kuntchito. Gwirizanani, m'nthawi yathu ino, pali eni magalimoto ambiri omwe ali ndi luso loyendetsa galimoto omwe samadziwabe yankho lomveka la funso losavuta: chifukwa chiyani tachometer imayikidwa pa chipangizo?
Ngakhale mutayang'ana pa intaneti ndi kuloweza mawu a sakramenti akuti: "Tachometer ndi chipangizo chomwe chimayesa liwiro la crankshaft ya galimoto mu mphindi imodzi," si dalaivala aliyense amene angamvetse chifukwa chake ayenera kutsatira izi. Ndipotu, kwa ambiri, chinthu chachikulu ndi chakuti chiwongolero ndi mawilo amazungulira.
Kumbali ina, ngati opanga magalimoto amawononga ndalama kukhazikitsa chipangizochi m'galimoto iliyonse yopanga, ndiye kuti ali otsimikiza kuti "helmsman" amafunikira. Koma, tsoka, kwenikweni, kuwerenga kwa tachometer kumayendetsedwa makamaka ndi madalaivala apamwamba, omwe, monga lamulo, amayendetsa magalimoto ndi gearbox yamanja kapena kugwiritsa ntchito buku la "automatic" mode.
Okonda ma drive otere amakhala ndi mwayi wozungulira injini mpaka kuthamanga kwambiri kuti apititse patsogolo mphamvu. Koma si chinsinsi kuti nthawi zonse kuyendetsa mu mode izi kwambiri amachepetsa moyo wa injini kuyaka mkati. Monga momwe kusuntha kwadongosolo kumathamanga otsika, sikukhala ndi zotsatira zabwino pa thanzi lake. Choncho, ndi zofunika kuti dalaivala aliyense azilamulira chizindikiro ichi, chomwe ndi ntchito yaikulu ya tachometer.
Kwa iwo omwe ali ofunikira kuti awonetsetse kuti injini ikuyenda bwino, kuyendetsa galimoto kuyenera kutsata liwiro labwino kwambiri, kusunga muvi mkati mwa malire ovomerezeka. Izi sizingowonjezera gwero la injini, komanso kupulumutsa malita owonjezera amafuta.
Pagalimoto iliyonse, malo abwino kwambiri pomwe muvi wa chipangizocho "umayenda" munjira yotetezeka ukhoza kukhala wosiyana malinga ndi mtundu wamagetsi ndi mawonekedwe ake. Koma nthawi zambiri zimakhala pakati pa 2000 ndi 3000 rpm.
M'magalimoto okhala ndi "mechanics" komanso ndi "automatic" mode, kuthamanga kwa kuyimba kwa tachometer kumayendetsedwa ndi kusintha kwa zida. Pamaso pa kufala kwadzidzidzi, izi zimachitika ndikuwongolera chopondapo cha gasi. Komanso, tachometer angagwiritsidwe ntchito kuzindikira injini zolakwika popanda kusiya galimoto. Ngati popanda ntchito liwiro "loyandama" ndipo muvi ukuyendayenda mopanda chilolezo kuzungulira kuyimba, ndiye kuti kwa dalaivala wodziwa izi chidzakhala chizindikiro chotsimikizika kuti ndi nthawi yoyendera galimoto.
Komabe, ndithudi, ambiri eni galimoto musadandaule za mutu uwu konse ndipo konse kuyang'ana tachometer, kukhulupirira kwathunthu kufala basi. Choncho pamapeto pake ndi bwino kuvomereza kuti chipangizo ichi chaikidwa m'magalimoto osati madalaivala, komabe kwa makina oyendetsa galimoto omwe amawagwiritsa ntchito panthawi yofufuza injini.
