Kodi n'zotheka kudzaza mafuta 5w40 m'malo mwa 5w30?

Limodzi mwa mafunso otchuka kwambiri pakati pa oyendetsa galimoto ndi kusinthana kwa mafuta agalimoto. M'mabwalo ambiri, mungapeze mafunso wamba monga: "Kodi n'zotheka kudzaza mafuta 5w40 m'malo 5w30?", "Kodi n'zotheka kusakaniza madzi amchere ndi synthetics kapena semi-synthetics?" ndi zina zotero. Tayankha kale ambiri mwa mafunsowa patsamba lathu la Vodi.su, ndipo tidasanthulanso mwatsatanetsatane mawonekedwe a SAE amafuta amafuta. Munkhaniyi, tiyesa kudziwa ngati kugwiritsa ntchito 5w40 m'malo mwa 5w30 ndikololedwa.

Engine mafuta 5w40 ndi 5w30: kusiyana ndi makhalidwe

Mawu akuti YwX, pamene “y” ndi “x” ali manambala ena, ayenera kusonyezedwa pazitini za injini kapena mafuta otumizira mafuta. Ili ndiye index ya viscosity ya SAE (Society of Automobile Engineers). Makhalidwe omwe ali mmenemo ali ndi tanthauzo ili:

• Chilembo cha Chilatini W ndi chidule cha English Winter - yozizira, ndiko kuti, mafuta ndi mafuta, kumene timawona kalata iyi, ikhoza kuyendetsedwa pa kutentha kwapansi pa zero;
• Nambala yoyamba - muzochitika zonsezi ndi "5" - imasonyeza kutentha kochepa komwe mafuta amapereka crankshaft cranking ndipo amatha kuponyedwa kudzera mumagetsi popanda kutentha kowonjezera, chifukwa cha 5W0 mafuta ndi mafuta chiwerengerochi chimachokera ku -35 ° C ( kutsekemera) ndi -25 °C (kutembenuka);
• manambala otsiriza (40 ndi 30) amasonyeza kutentha osachepera ndi pazipita fluidity posungira.

Choncho, monga sikovuta kulingalira, malinga ndi gulu la SAE, mafuta a injini ali pafupi ndi mzake ndipo kusiyana pakati pawo kuli kochepa. Timalemba kuti timveke bwino monga mndandanda:

1. 5w30 - amasunga mamasukidwe akayendedwe pa kutentha yozungulira osiyanasiyana kuchoka 25 mpaka kuphatikiza 25 madigiri;
2. 5w40 - yopangidwa kuti ikhale yotalikirapo kuyambira 25 mpaka kuphatikiza madigiri 35-40.

Dziwani kuti kutentha kwapamwamba sikofunikira ngati kutsika, chifukwa kutentha kwa mafuta mu injini kumakwera kufika madigiri 150 ndi pamwamba. Ndiye kuti, ngati muli ndi mafuta a Mannol, Castrol kapena Mobil 5w30, izi sizikutanthauza kuti paulendo wopita ku Sochi, kumene kutentha kumakwera pamwamba pa madigiri 30-40 m'chilimwe, ziyenera kusinthidwa nthawi yomweyo. Ngati mumakhala kotentha nthawi zonse, ndiye kuti muyenera kusankha mafuta ndi mafuta omwe ali ndi nambala yachiwiri yapamwamba.

Ndipo kusiyana kwina kofunikira pakati pa mitundu iwiriyi yamafuta ndi kusiyana kwa mamasukidwe akayendedwe. The zikuchokera 5w40 ndi viscous kwambiri. Choncho, kuyamba galimoto pa kutentha otsika n'kosavuta ngati wodzazidwa ndi mafuta ochepa viscous - mu nkhani iyi, 5w30.

Ndiye ndizotheka kutsanulira 5w30 m'malo mwa 5w40?

Mofanana ndi funso lina lililonse lokhudza kayendedwe ka magalimoto, pali mayankho ambiri ndi zambiri "buts". Mwachitsanzo, ngati pali vuto lalikulu, kusakaniza mitundu yosiyanasiyana ya mafuta ndi mafuta ndikovomerezeka, koma pambuyo pake mungafunike kutulutsa injini. Choncho, kuti apereke malingaliro a akatswiri kwambiri, m'pofunika kusanthula luso la galimotoyo, malangizo a wopanga, ndi momwe amagwirira ntchito.

Timalemba zochitika zomwe kusintha kwa mafuta okhala ndi index yayikulu ya viscosity sikutheka, koma nthawi zina kumangofunika:

• pakugwira ntchito kwa nthawi yayitali kwa galimotoyo m'madera okhala ndi nyengo yotentha;
• ndi kuthamanga pa odometer makilomita oposa 100 zikwi;
• ndi kutsika kwa psinjika mu injini;
• pambuyo kukonzanso injini;
• ngati chopukutira kuti chigwiritsidwe ntchito kwakanthawi kochepa

Inde, atadutsa makilomita 100, mipata pakati pa pistoni ndi makoma a silinda amawonjezeka. Pachifukwa ichi, mafuta ochulukirapo ndi mafuta amachuluka, kutsika kwa mphamvu ndi kuponderezana. Mafuta ochulukirapo a viscous ndi mafuta amapanga filimu yowonjezereka pamakoma kuti achepetse mipata. Chifukwa chake, posintha kuchokera ku 5w30 kupita ku 5w40, mumawongolera magwiridwe antchito ndikukulitsa moyo wagawo lamagetsi. Zindikirani kuti m'malo opangira mafuta owoneka bwino, kuyesetsa kochulukirapo kumagwiritsidwa ntchito popukusa crankshaft, chifukwa chake kuchuluka kwamafuta sikungachepetse kwambiri.

Mikhalidwe yomwe kusintha kuchokera ku 5w30 kupita ku 5w40 kumakhala kosafunika kwambiri:

1. mu malangizo, wopanga analetsa kugwiritsa ntchito mitundu ina ya mafuta ndi mafuta;
2. galimoto yatsopano posachedwa kuchokera ku salon pansi pa chitsimikizo;
3. kuchepa kwa kutentha kwa mpweya.

Komanso choopsa kwambiri kwa injini ndi mkhalidwe wa kusakaniza lubricant ndi fluidity osiyana. Mafuta sikuti amangopaka malo, komanso amachotsa kutentha kwakukulu. Ngati tisakaniza zinthu ziwiri zosiyana za fluidity ndi viscosity coefficients, injini idzatentha kwambiri. Nkhaniyi ndi yofunika kwambiri pamagetsi amakono apamwamba kwambiri. Ndipo ngati pamalo operekera chithandizo mumapatsidwa kuti mudzaze 5w30 m'malo mwa 5w40, kulimbikitsa izi chifukwa cha kusowa kwamafuta ofunikira m'nyumba yosungiramo katundu, musavomereze, chifukwa pambuyo pakusintha kotereku kutentha kumakulirakulira, zomwe ndi wodzala ndi mulu wonse wamavuto okhudzana.

anapezazo

Kutengera zonse zomwe tafotokozazi, timapeza kuti kusintha kwamtundu umodzi kapena wina wamafuta ndi mafuta ndikotheka pokhapokha mutaphunzira mwatsatanetsatane za mawonekedwe amagetsi ndi zofunikira za wopanga. Ndikoyenera kupewa kusakaniza mafuta kuchokera kwa opanga osiyanasiyana komanso pazoyambira zosiyanasiyana - zopanga, semi-synthetics. Kusintha koteroko ndi koopsa kwa magalimoto atsopano. Ngati mtunda ndi waukulu, m'pofunika kukaonana ndi akatswiri.
