5W40 ọ bụ mmanụ kachasị mma mgbe niile?

Mmanụ engine nwere akara 5W40 eleghị anya, ụdị mmanụ engine a na-ahọrọkarị maka ụgbọ ala ndị njem. Ma gịnị ka mbiri nke a pụtara na ọ ga-egosi mgbe niile mmanụ kacha mma maka ụgbọ ala anyị?

Mmanụ nwere ọtụtụ ọrụ dị mkpa - na-ajụ oyi akụkụ na-akpụ akpụ nke injin, na-ebelata esemokwu na ịnya ụgbọ ala, akara akụkụ na-akpụ akpụ na ọbụna na-eme ka engine dị ọcha na na-egbochi corrosion... Nke a bụ ya mere o ji dị mkpa iji mmanụ na-echebe engine kacha mma.

Ụzọ dị mkpụmkpụ karị, mmanụ ahụ dị mkpa karị

A na-ejikọta ọrụ nke engine na ọrụ mmanụ. Otú ọ dị, ọ bara uru ịmara na engine na-akawanye njọ ọ bụghị mgbe, dịka ọmụmaatụ, ụgbọ ala na-agba ọsọ na-agba ọsọ n'okporo ụzọ, ma. mgbe ịmalite na emenyụ... Ya mere, njem dị mkpirikpi bụ ihe kacha sie ike maka injin.

O nwere ike ịbụ ihe ijuanya, mana ọ bụrụ na ị na-anya ụgbọ ala maka obere oge, ị ga-achọ mmanụ ka mma karịa ma ọ bụrụ na ị na-anya ọtụtụ narị kilomita na-adịghị akwụsị akwụsị. Ezigbo mmanu ịgbatị ndụ nke onye engine componentsna n'ezie - ọ ga-enye gị ohere ịmalite engine na ọnọdụ ihu igwe kachasị njọ (dịka ọmụmaatụ, na ntu oyi siri ike).

Ọ na-ekpo ọkụ karị, na-ebelata viscosity.

Isi oke nke mmanụ bụ viscosity ya. Ka mmanụ na-ekpo ọkụ, viscosity ya na-ebelata. Ka injin ahụ na-ajụ oyi, viscosity na-abawanye.. N'ikwu ya n'ụzọ ọzọ - na okpomọkụ dị elu, oyi akwa mmanụ na-adị gịrịgịrị, na mgbe anyị na-agbakwunye trottle na engine na-ekpo ọkụ, obere rpm na mmanụ ezughị ezu, engine nwere ike ịla n'iyi maka oge!

Agbanyeghị, enwere ike ịnwe nsogbu mmanụ ahụ dị oke viscousdị ka ọ nwere ike iru n'otu n'otu n'ime engines kwa nwayọọ nwayọọ.

0W kacha mma maka ntu oyi

N'ebe a, anyị kwesịrị ime ihe mgbawa site na ọkwa viscosity. Oke nwere leta W (ọtụtụ mgbe site na 0W ruo 20W) na-egosi viscosity oyi. Obere oke W, ka nguzogide ntu oyi na-abawanye..

0W mmanụ ga-eguzogide ọtụtụ frosts - engine kwesịrị ịmalite ọbụna na okpomọkụ n'okpuru -40 degrees Celsius. Mmanụ 20W na-eme ihe kachasị njọ na obere okpomọkụnke nwere ike igbochi engine ịmalite na -20 degrees.

Mmanụ injin na-ekpo ọkụ

Mana nke ahụ abụghị ihe niile, n'ihi na oke nke abụọ dịkwa mkpa. Ọnụọgụ e mechara leta W na-egosi mmanụ viscosity mgbe engine na-ekpo ọkụ na okpomọkụ na-arụ ọrụ nke ọma (ihe dịka 90-100 degrees Celsius).

Ogo viscosity kacha ewu ewu bụ 5W40.. Mmanụ dị otú ahụ n'oge oyi na-eme ka o kwe omume ịmalite engine na okpomọkụ nke -35 degrees, na mgbe ọ na-ekpo ọkụ, ọ na-enye viscosity nke kacha mma maka ọtụtụ nkeji ike. Maka ọtụtụ - mana ọ bụghị maka mmadụ niile!

Mmanụ viscosity dị ala

A na-akpọ mmanụ nke 20 ma ọ bụ 30 ọkwa mmanụ azọpụta ike... Na ala viscosity, na-ebelata mmanụ nguzogide, nke pụtara obere ọnwụ nke engine ike. Otú ọ dị, mgbe ọkụ, ha na-etolite ọtụtụ ihe nkiri nchebe dị mkpa.

Nke a dị ala viscosity na-enye ohere ka mmanụ na-agba ọsọ ngwa ngwa n'etiti akụrụngwa engine, ma n'ọtụtụ powertrains, nchebe a agaghị ezuru. N'ọnọdụ dị otú ahụ engine nwere ike na-agbaji.

Ọtụtụ mgbe, a na-agbanye mmanụ nke ụdị a n'ime engines nke oge a - ọ bụrụhaala na onye nrụpụta na-akwado iji mmanụ nke viscosity a.

Mmanụ viscosity dị elu

Mmanụ nke akara 50 na 60, n'ụzọ megidere nke ahụ, nwere viscosity dị elu, ya mere, n'ụzọ ihe atụ, ha yiri "oke". N'ihi ya, ha na-etolite a thicker oyi akwa mmanụ na ha mma na-echebe moto si bufee ibu... Ojiji nke mmanụ dị otú ahụ nwere ike inwe mmetụta na-adịghị mma na oriri mmanụ na ike.

Ụdị mmanụ a na-ejikarị eme ihe. n'ime igwe ndị na-eyi nke ọma, nakwa na ndị "nara mmanụ". Mmanụ na-egbuke egbuke nwere ike ibelata oriri mmanụ na ọbụna, n'ihi njirimara akara ha. belata mkpụgharị engine... Ma ọ na-eme na elu-viscosity mmanụ a na-akwado ha maka ụgbọ ala egwuregwuiji chekwaa draịva gị siri ike nke ọma nke na-achọsi ike.

Ekwesịrị m ịgbanwe viscosity?

Na-aza ajụjụ aha, Mmanụ 5W40 (ma ọ bụ 0W40) ezigbo ika (dịka. Castrol, Liqui Moly, Elf) ga-abụ nhọrọ kacha mma n'ọtụtụ ọnọdụ.
