I-brake fluid. Imiphumela yokuhlolwa eyethusayo

Ngokocwaningo olwenziwa yi-Automotive Institute, amabhuleki ama-DOT-4 ama-brake fluids amane kwayishumi awahlangabezani nezindinganiso ezithile. Uketshezi olusezingeni eliphansi luyakhula, futhi ezimweni ezimbi kakhulu lungaphuca imoto amandla okwehlisa ijubane.

Isikhungo Sesayensi Yezinto Zokusebenza se-Institute of Road Transport sihlole ikhwalithi yoketshezi lwamabhuleki lwe-DOT-4 oludumile emakethe yasePoland. IQuality Compliance Analysis ihlanganise imikhiqizo eyishumi edumile yezimoto. Ochwepheshe be-ITS bahlolile, okuhlanganisa inani lamaphuzu abilayo kanye ne-viscosity, i.e. amapharamitha anquma ikhwalithi yoketshezi.

– Imiphumela yokuhlolwa ibonise ukuthi uketshezi olune kweyishumi aluhlangabezani nezidingo ezishiwo ezingeni. Iziphuzo ezine zabonisa ukuthi indawo yokubilisa yayiphansi kakhulu, futhi ezimbili zazo zicishe zahwamuka ngokuphelele ngesikhathi sokuhlolwa futhi azizange zibonise ukumelana ne-oxidation. Endabeni yayo, imigodi yokugqwala yavela nasezintweni zaselabhorethri,” kuchaza u-Eva Rostek, inhloko ye-ITS Materials Research Center.

Eqinisweni, ukusetshenziswa kwalolo hlobo (olusezingeni eliphansi) lwamabhuleki lungakhuphula amakhilomitha futhi, ezimweni ezimbi kakhulu, kwenze kungenzeki ukuthi imoto ime.

I-Brake fluid ilahlekelwa izakhiwo zayo ngokuya ngeminyaka, ngakho abakhiqizi bezimoto batusa ukuyishintsha okungenani kanye njalo eminyakeni emibili kuya kwemithathu. Naphezu kwalokhu, ucwaningo ngo-2014 lwabonisa ukuthi amaphesenti angu-22 Abashayeli basePoland abakaze bamshintshe, futhi abangamaphesenti angu-27 bashintsha. izimoto ezihloliwe, wayenelungelo lokushintsha ngokushesha.

- Kumele sikhumbule ukuthi i-brake fluid i-hygroscopic, i.e. imunca amanzi endaweni ezungezile. Amanzi amancane, ayanda amapharamitha abilayo futhi ayanda ukusebenza kahle komsebenzi. Iphuzu elibilisayo loketshezi lwekilasi le-DOT-4 akufanele libe ngaphansi kuka-230 ° C, futhi uketshezi lwekilasi le-DOT-5 akufanele lube ngaphansi kuka-260 ° C, lukhumbuza u-Eva Rostek kusuka ku-ITS.

Amabhuleki asebenzayo anoketshezi lwekhwalithi ephezulu ohlelweni afinyelela amandla awo agcwele cishe imizuzwana engu-0,2. Empeleni, lokhu kusho (ukuthatha ukuthi imoto ehamba nge-100 km/h ihamba ibanga elingu-27 m/s) ukuthi ukubhuleka akuqali kuze kube amamitha angu-5 ngemva kokufakwa kwebhuleki. Ngoketshezi olungahlangabezani nemingcele edingekayo, ibanga lokubhuleka lizokhuphuka lize lifike izikhathi ezingu-7,5, futhi imoto izoqala ukwehla ngamamitha angu-35 kuphela kusukela lapho ucindezela i-pedal yebhuleki!

Izinga le-brake fluid lithinta ngokuqondile ukuphepha kokushayela, ngakho-ke lapho ukhetha, landela izincomo zabakhiqizi bezimoto futhi uthenge amaphakheji avaliwe kuphela.
