4 zvikonzero zvikuru nei tachometer yakakosha pakuita kwemotokari

Kazhinji inongoonekwa mumotokari dzekufambisa, iyo tachometer yakakosha pakuunganidza data, kushandura giya, hupfumi hwemafuta, uye hupenyu hweinjini.

Mota dzemazuvano, marori uye maSUV ari kuramba achitsamira patekinoroji gore rega rega. Kubva pamasisitimu ekuchengetedza anobatsirwa nemutyairi kuenda kune yepamusoro peturu system yekutarisa uye kugadzirisa software, mutyairi wemazuva ano akasiyana zvakanyanya neaya ekare. Chimwe chezvinhu zvakasara (kazhinji pamotokari dzine giya rekuchinja) ndiyo tachometer. Mumakore apfuura, "tachometer" yaishandiswa nemutyairi kuona nguva yakanakisisa uye yakanakisisa yekuchinja kubva pasi kusvika kune yakakwirira. Nhasi, tachometer yekuona haina kukosha sezvayakanga yakaita makore apfuura, asi inoshandisa chinangwa.

Kunzwisisa chinangwa chaicho che tachometer

Kusiyana nezvinodavirwa nevakawanda, tachometer inopfuura geji rinoratidza kumhanya kweinjini. Muchokwadi, iyo tachometer ine sisitimu yemidziyo yekudzora inounganidza data, inoendesa kune ECU (injini yekudzora unit) uye inokanganisa kushanda kweanoverengeka akazvimirira masisitimu. Zviri pamutemo, tachometer chishandiso chinoyera kutenderera kweinjini crankshaft, iyo inokonzeresa kutenderera kweimwe neimwe tsvimbo yekubatanidza uye piston mukutenderera kutenderera. Kana crankshaft ichitenderera 360 madhigirii, inopedza shanduko yakakwana. Yese kumhanya kwekutenderera kwe crankshaft inoyerwa mumarevolutions paminiti kana rpm.

Iyo RPM inoratidzwa pane geji, kazhinji inowanikwa pane dhibhodhi yemutyairi uye, kazhinji, kuruboshwe. Inowanzoratidza nhevedzano yenhamba kubva pazero kusvika pa8 kana 9 ine mitsetse yakati wandei pakati peimwe nhamba paanalogi kana dhijitari kuratidzwa. Nhamba iri pakati pa 0 na 9 inotsanangurwa sechi1,000 kupeta nhamba iyoyo. Nhamba dzekupedzisira dzinoratidzwa pa tachometer dzinowanzoratidzwa mutsvuku. Kana injini iri kukurumidza, museve unonongedzera kune nhamba yakaenzana neinjini rpm. Kana museve wakanongedza kune mucherechedzo mutsvuku, unoonekwa se "redline" kana kushanda pamusoro peinokurudzirwa.

Kuziva basa re tachometer, ngationei 4 zvikonzero zvikuru nei zvakakosha pakushanda kwemotokari.

1. Inobata uye kutumira data kubatsira kushandura mota yako

Kana iwe uine otomatiki kutapurirana uye uine tachometer, iwe unozoona kumwe kuenderana kana uchichinja kubva pagiya rezasi kuenda kune yakakwira giya. Iyo dhizaini yakarongerwa kukwidziridzwa pane yakapihwa injini kumhanya. RPM inoyerwa netachometer yoendeswa kuTCM (Transmission Control Module) kana ECU. Iwo marevolutions akafanana anoratidzwa pane geji. Nepo chiyero pachacho chiri chezvinangwa zvekuratidzira chete, chinoita kuti mutyairi azive nguva yekutarisira shanduko.

2. Rega madhiraivha ekufambisa azive nguva yekuchinja

Iyo tachometer sensor inobatsirawo mutyairi kuziva nguva yekuchinja giya rega rega paunenge uchishanda dhairekitori. Mota zhinji, marori, uye maSUV ane manual shifting anofanirwa kusimuka kubva pasi kuenda kumusoro kana tachometer ichiverenga pakati pe3,000 and 4,000 engine rpm. Vatyairi vanowanzodzidziswa kushandura injini zvichienderana nezwi uye kutyaira mamiriro pane revs ye tachometer, asi tachometer inoshanda basa rinokosha nekupa chiratidzo chekuona.

3. Inobatsira Kuvandudza Kushanda Kwemafuta

Tachometer inoshanda inogonawo kubatsira avo vane manual transmission kuvandudza hupfumi hwavo hwemafuta. Vazhinji vagadziri vemota vanotsanangura mugwaro remuridzi wemota pane iyo RPM injini inofanirwa kuchinjirwa kuti inyatsoshanda. Kuti uwane kunyatsoshanda, injini yemazuva ano yekupisa yemukati inosanganiswa neimwe mhando yekutapurirana kana kutapurirana uye dhiraivha axle ratio. Iko kusanganiswa kweatatu ese akasiyana masisitimu anozivikanwa sechitima chemagetsi. Kuchinja kunokurudzirwa nemugadziri kunobatsira kufambisa simba kumavhiri nekukweva kushoma. Nekuderedzwa "mutoro" kana "kudhonza" painjini, mafuta mashoma anopiswa, zvichikonzera hupfumi huri nani.

4. Inowedzera hupenyu hweinjini.

Injini yemoto yemukati ine zvikamu zvakati wandei zvinofamba zvinoda lubrication kuti ishande. Sezvo chikamu chimwe nechimwe chinofamba, kukwesha kunogadzirwa nekutenderera kwese kweinjini, uyezve, kupisa. Iyo inokurumidza iyo injini inotenderera (kana iyo yakakwirira iyo RPM), ndiko kuwedzera kupisa kunogadzirwa. Kana izvi zvikaitika, simbi dzinenge dzasangana dzinopedzisira dzapisa kusvika dzatanga kurasikirwa nemafuta, izvo zvinogona kukonzera kukundikana kukuru. Kana iyo tachometer uye zvikamu zvekuwedzera zviri kushanda nemazvo, kutapurirana kunogona kuchinja nenguva, kana madhiraivha ekutapurirana anogona kuchinja sezvaanokurudzirwa, achiwedzera hupenyu hweinjini.

Iyo tachometer inoita basa rakakosha muinjini yemazuva ano sezvo ichienda zvakanyanya kupfuura kungoita tsono inofamba pane geji. Kana iwe ukacherechedza kuti tachometer sensor haisi kushanda, inogona kuva chiratidzo chechinetso chiduku, chakadai senzwi rakaputsika kana tambo yakasununguka, kana dambudziko rinogona kunge rakakomba, rakadai seyakanganisika nguva sensor. Kana iwe uchifungidzira kuti tachometer haisi kushanda pamotokari yako, taura nenyanzvi makanika uye uite kuti vaongorore chakakonzera dambudziko kuitira kuti kugadzirisa kwakakodzera kuitwe.
