Tachometer. Momwe mungawerenge ndikugwiritsa ntchito umboni wake?

Tachometer m'galimoto si chida chapamwamba. Ndi chida chothandiza chomwe chingagwiritsidwe ntchito m'njira zosiyanasiyana.

Ngati sitiyang'ana kuwerengera kwa tachometer, sitingathe kudziwa molondola liwiro lozungulira pomwe shaft yayikulu ya injini yagalimoto yathu ikuyenda. Ndipo m'pofunika kudziwa chifukwa ndi mfundo zofunika kwambiri. Kuyendetsa kulikonse kumakhala ndi mawonekedwe ake omwe amatsimikizira machitidwe ake pakugwiritsa ntchito tsiku ndi tsiku. Poyang'anira liwiro la injini, mutha kugwiritsa ntchito mawonekedwe kuti mukwaniritse zabwino zina. Kutengera liwiro la injini, titha kugwiritsa ntchito bwino kwambiri mphamvu zamagetsi tikamayendetsa mwachangu, kapena titha kuyendetsa mofatsa komanso mosatekeseka momwe tingathere, kupeza mafuta otsika kwambiri.

Kuti agwiritse ntchito tachometer molondola, dalaivala ayenera kudziwa za makhalidwe a injini. Popanda chidziwitso chotere, tachometer idzakhala chinthu chopanda ntchito cha dashboard. Ndikofunikira kudziwa mapindikidwe a torque, mayendedwe a chithunzi chake komanso liwiro lomwe mtengo wake umapezeka. Ndikofunikiranso kudziwa kuti mphamvu yayikulu ya injini ikuwoneka pa rpm, komanso momwe ma torque ndi zithunzi zamphamvu zimadutsa pazithunzi za injini.

Akonzi amalimbikitsa:

Layisensi ya dalayivala. Kusintha Kujambula Mayeso

Momwe mungayendetsere galimoto ya turbocharged?

Utsi. Malipiro atsopano oyendetsa

Pakuyendetsa kwamphamvu kapena kwamasewera, cholinga chake ndikusunga liwiro la injini pamlingo womwe umalola kuti torque yayikulu ipangidwe. Mwachidule, torque ndiyomwe imayambitsa mathamangitsidwe, osati mphamvu yayikulu. Injini imagwira ntchito bwino kwambiri pakati pa RPM yokhala ndi torque yayikulu ndi RPM yokhala ndi mphamvu yayikulu. Kutalikirana kwamtunduwu, injiniyo imasinthasintha kwambiri. Pakugwiritsa ntchito tsiku ndi tsiku, izi zikutanthauza kuti mutha kufulumizitsa mwachangu pama liwiro awa osasintha magiya. Choncho, m'pofunika kudziwa ndi kukumbukira liwiro osiyanasiyana imene injini ali ndi mphamvu yaikulu katundu. Kuti zikhale zosavuta kuyika zizindikiro pa tachometer. Zabwino kwambiri pakuthamanga kothandiza kwambiri ndikusintha magiya panthawi yomwe injiniyo ikasintha, imayamba kuthamanga kuchokera pa liwiro lomwe imafikira kapena kuyandikira torque yayikulu. Ndiye iye ali ndi mphamvu yaikulu yogonjetsa kukana kusuntha chifukwa cha kulemera kwa galimoto, kukangana ndi kukana mpweya. Zowonjezera zomwe zimaperekedwa ndi tachometer ndi chakuti injini ikufika pazipita zake, RPM yotetezeka. Izi zikuwonetsedwa ndi munda wofiira kumapeto kwa sikelo ndi kudula mu dongosolo la jekeseni. Kugwiritsira ntchito injini kunja kwa RPM yovomerezeka kungawononge galimotoyo. Nthawi zambiri, kupanikizana kwa injini kapena ndodo yolumikizira imasweka.

Poyendetsa galimoto ndikugogomezera mafuta otsika kwambiri, kudziwa mawonekedwe a injini kumathandizanso kwambiri. Zoona, madalaivala ambiri amatsatira mfundo yakuti crankshaft imayenda pang'onopang'ono, mafuta ochepa amatha kudutsa m'zipinda zoyaka, koma pali msampha m'malingaliro awa. Eya, injiniyo sayenera kupitirira liwiro linalake pa giya iliyonse. Cholinga chake ndikupewa zochitika zovulaza zomwe zimafulumizitsa kwambiri kuvala kwa mayendedwe a shaft ndi kulumikiza ndodo. Kuyendetsa pang'onopang'ono ndi mtundu wachuma chabodza. Kuyendetsa bwino kungathe kuphatikizidwa bwino ndi mafuta ochepa, koma izi zimafuna tachometer ndi chidziwitso cha makhalidwe a injini. Momwemo, kudziwa mawonekedwe onse akunja, ndi graph yogwiritsira ntchito mafuta (ndikosavuta kudziwa liwiro lopindulitsa kwambiri). Koma ngakhale pamaziko a chithunzi cha mphamvu-makokedwe, n'zotheka kudziwa osiyanasiyana zosintha yabwino mawu mafuta. Mtengo wawo ndi pafupifupi theka la zosinthika pakati pa torque yayikulu ndi mphamvu yayikulu. Mwa kusunga injini pafupi ndi mtengo uwu, powerenga tachometer, mudzaonetsetsa kuti mukuyenda bwino komanso kugwiritsa ntchito mafuta ochepa.
