Kusarudzwa kwemafuta egiya kunobatsira kusarudza iyo chaiyo kuumbwa

Kurongeka kwepasirese kwemafuta ekutepfenyura kunobvumira varidzi vemotokari kuti vasarudze zviri nyore iyo yakakwana yekufambisa kuumbwa kwemabhokisi egiya, makesi ekufambisa, cheni uye madhiraivha egiya, nzira dzekufambisa dzebhiza ravo resimbi.

API kupatsanurwa kwemafuta egiya

Iro hurongwa hwekupatsanura hunopatsanura marudzi ese emakomboni kuita makirasi mashanu. Mutevedzeri wayo weEuropean ZF TE-ML, iyo inotsanangura zvachose zvinyorwa zvese zve hydromechanical transmissions. Aya anotevera API mapoka anosiyaniswa zvichienderana nemisimboti yekushanda uye dhizaini yekufambisa, vhoriyamu yezvakakosha zvinowedzera:

• GL-1: zvinwiwa zvisina zvinowedzera, zvinokwanisika kuwedzera anti-furo, antioxidant, depressant, anti-corrosion additives kune mamwe mabhureki emafuta egiya muhuwandu hudiki. Inokodzera marori nemichina inoshandiswa mukurima.
• GL-2: kazhinji inodururwa mukufambiswa kwezvikamu zvekurima, zvine anti-kupfeka zvinowedzera.
• GL-3: haikodzeri magiya ehypoid, huwandu hwezvinowedzera zvakakosha izvo zvinoderedza kupfeka pazvikamu zvemotokari zvingangoita 2,7 muzana.
• GL-4: maumbirwo anoshandiswa mumagiya akawiriraniswa anoshanda pasi pemamiriro akasiyana-siyana egiravhiti, mumagiya makuru echero chekutakura uye asina kuwiriraniswa magiya mabhokisi. GL-4 zvinwiwa, zvinoenderana neiyo API kupatsanura kwemafuta egiya, ine ina muzana muzana EP yekuwedzera.
• GL-5: haishandiswe kumabhokisi egiya, asi, kuva pasi rose, akakodzera chero mamwe mafambisirwo, ane huwandu hwakawanda hweakawanda ekuwedzera ekuwedzera (kusvika 6,5%).

Gear oiri classification system

SAE Gear Oiri Viscosity

Iyo yakajairika yekuAmerican kupatsanura egiya maoiri ne viscosity muchimiro cheakasiyana akajairwa mayunitsi. Makambani ekufambisa emotokari anotora zvakatemwa zveSAE. Uye pahwaro hwavo vanopa kurudziro pasarudzo yekutumira nziyo dzemakina magiya mabhokisi uye maaxles (anotungamira). Iyo giya yemafuta viscosity index (semuenzaniso, 85W0140) inoratidza iwo makuru maparamita emvura uye inokamura muzhizha nechando (bhii "W"). Uku kumaka kwemafuta egiya kuri nyore uye kunonzwisisika kune vatyairi.

Zvakakosha kuziva kuti mafuta egiya anosarudzwa sei: kusarudzwa uye kusarudzwa kwezvinyorwa kunoitwa maererano nezviratidzo zviviri zve viscosity - yakakwirira uye yakaderera tembiricha. Chiratidzo chekutanga chinotorwa pahwaro hwekinematic viscosity panzvimbo yekubikira yemvura, yechipiri - nekuyera tembiricha iyo inoumbwa ine chiratidzo che150000 cP (Brookfield viscosity). Iko kune yakakosha tafura yeviscosity yemafuta egiya, ayo vanogadzira vanotungamirwa nayo.

Kusarudzwa kwemafuta ekutakurisa nemhando yemota

Kunyanya, kusarudzwa kwakadaro hakusi kwakaoma kuita iwe pachako, kana iwe ukadzidza mazano ekugadzirisa uye kusarudzwa kwemafuta emagetsi. Kutanga iwe unofanirwa kutarisa kubvumidzwa kwemugadziri wemotokari kune chaiyo komisheni inoshandiswa pamotokari yako, pamwe nekuona kwemafuta egiya zvinoenderana neSAE. Uye wobva wabata nekirasi yemhando yemvura zvinoenderana neEuropean (ACEA) neAmerican (API) kupatsanurwa kwemagiya emafuta mabhureki:

• kune peturu injini - ACEA (A1-A5): mhando inoonekwa seyakakwirira, iyo yakakura nhamba mushure metsamba A;
• yeinjini dzedhiziri - ACEA (B1-B5);
• universal for diesel units yakaiswa pamotokari mushure me2004 - ACEA (С1-С5);
• nokuda kwemotokari dizeli injini - API boka "C";
• peturu injini - API boka "S".

Uye usakanganwa kuti pasherufu yemafuta egiya kazhinji inogumira kumakore mashanu kubva pazuva rekugadzirwa.
