Duk jerin K suna nuna canji a cikin tsararraki da fifiko ga Honda. Motoci na wannan jerin sun fara jujjuya agogon agogo, an maye gurbin motar a nan tare da sarkar daya, kuma ana amfani da sabon tsarin VTEC - iVTEC a cikin waɗannan injinan. Akwai sauran hanyoyin fasaha da ra'ayoyi. Sama da shekaru goma ana samun nasarar sarrafa wadannan injuna akan sabbin motocin Honda, wadanda ke da matukar bukata ta fuskar muhalli da tattalin arziki. Suna cinye ɗanyen mai, kuma shaye-shayen ya ƙunshi ƙananan abubuwa masu cutarwa ga muhalli.
Mafi mahimmanci, ƙwararrun ƙwararrun Honda sun sami damar daidaita motocin, suna ba da kyakkyawan ƙarfi da ƙarfi. A versatility na dandamali ne ma da - K24 engine samu daban-daban gyare-gyare tare da gyare-gyare halaye, wanda ya sa ya yiwu a yi amfani da su a kan daban-daban motoci.
Musamman abin lura shine tsarin iVTEC, wanda ke tsara lokacin lokaci kuma yana ba ku damar cimma mafi kyawun amfani da man fetur. Hatta injunan iVTEC mai lita 2.4 na amfani da man fetur dan kadan fiye da injinan lita 1.5 na zamanin baya. Tsarin ya nuna kansa daidai lokacin da ake ɗaukar sauri - injuna tare da wannan fasaha ba su wuce 12-14 lita / 100 km ba yayin tuki mai ƙarfi na birni, wanda shine kyakkyawan sakamako ga injin lita 2.4.
Saboda wadannan abũbuwan amfãni, da K-jerin Motors ya zama mashahuri kuma masu motoci sun sami karbuwa sosai, amma bayan wani lokaci matsaloli sun fara bayyana dangane da amincin zane.
babbar matsalar
Babbar matsala tare da injunan K-jerin (ciki har da nau'ikan lita 2.4) shine camshafts masu shayewa. A wani lokaci, sun gaji sosai kuma kawai sun kasa buɗe bawul ɗin shaye-shaye daidai. A zahiri, injuna tare da sawa camshaft ba su yi aiki daidai ba. Alamar alama tana ninki uku, a layi daya, yawan man fetur ya karu, kuma an lura da saurin ninkaya. Hakan ya tilastawa masu motocin kawar da su, inda a baya suka gyara bangaren wutar lantarki. Wasu ma ba su yi gyare-gyare ba saboda tsadar sassa da sabis na injiniyoyi - a matsakaita, jimlar kuɗin gyaran ya kasance dalar Amurka 700-800. Wannan ya kara tsanantawa da gaskiyar cewa bayan gyarawa da maye gurbin camshaft na shaye-shaye, bayan wani lokaci tare da amfani mai ƙarfi, matsalar ta sake bayyana - riga tare da sabon camshaft.
A lokacin gyaran, babu wanda zai iya ba da tabbacin cewa sabbin sassa za su daɗe na dogon lokaci, a lokuta da yawa, gabaɗayan kan silinda ya buƙaci maye gurbin, tunda ko da gadon camshaft yana da alaƙa da lalacewa. Bayan bincike mai zurfi na lokuta daban-daban, masana sun yanke shawarar cewa matsalar tana cikin tsarin samar da man shafawa ga taron, amma menene daidai yake da shi - babu wanda ya sani. Akwai ka'idar cewa matsalar ta ta'allaka ne a cikin kunkuntar tashoshi na samar da mai ga camshaft, amma wannan ba tabbas bane.
Wasu masana sun yi iƙirarin cewa Honda kawai ta yi kuskuren ƙididdige abubuwan da ke cikin gami don gina camshafts, kuma an gabatar da nau'ikan nau'ikan nau'ikan kayan gyara marasa lahani. Ana zargin, Honda ya fara sarrafa ingancin sassan da aka yi amfani da shi da kyau kuma ya ba da damar camshafts marasa inganci su shiga na'urar.
Har ila yau akwai ka'idodin makirci. A cewarsu, da gangan ƙwararrun Honda suka ƙirƙiro sassa masu ƙarancin albarkatu ta yadda ake kawo motoci a tashoshin sabis na hukuma akai-akai.
Wanne sigar daidai ba a sani ba, amma gaskiyar ita ce, da gaske an yi sabbin camshafts ta amfani da wata fasaha ta daban. A kan tsohon "Honda" Motors na D da B jerin an yi amfani da taurare camshafts - gwaje-gwaje sun tabbatar da wannan. Idan an jefa wannan ɓangaren injin ɗin B ko D akan bene na siminti, zai karye zuwa guda da yawa, amma camshaft daga injin K zai kasance cikakke.
Lura cewa a kan wasu injunan K-jerin babu irin waɗannan matsalolin, a kan wasu kuma dole ne a maye gurbin camshafts kowane kilomita 20-30. Bisa ga lura da masu sana'a da masu sana'a, matsalar sau da yawa taso a kan injuna cike da danko mai - 5W-50, 5W-40 ko 0W-40. Wannan ya kai ga ƙarshe cewa K-jerin Motors bukatar wani bakin ciki mai da danko na 0W-20, amma wannan kuma bai bada garantin dogon engine rayuwa.
Sauran matsaloli
Batun da ba shi da mahimmanci shine rashin aiki na solenoid da kuma bakon fashewar kayan VTC. Matsala ta ƙarshe tana faruwa akan injunan K24 tare da haɓakawa. Ba a san ainihin musabbabin wadannan matsalolin ba, amma akwai shakkun samun sauyin man da bai dace ba. Bude taron yana ba ku damar sanin mummunan lalacewa da yunwar mai ke haifarwa, toshewar taro da mai da wuya ba a gano shi ba, wanda ya yi amfani da masara a lokacin aiki na dogon lokaci.
Akwai kuma wasu matsalolin "classic":
- Gudun iyo - ana warware ta ta hanyar tsaftace ma'auni da KXX.
- Jijjiga - akan sawa injiniyoyi, bel ɗin lokaci na iya shimfiɗawa, wanda ke haifar da girgiza. Hakanan yana da kyau a duba hawan injin.
- Ruwan mai - a mafi yawan lokuta, matsalar ta ta'allaka ne a gaban hatimin crankshaft mai. Sauya shi zai magance wannan matsalar.
Anan ne matsalolin suka ƙare. Idan ka ware matsalar tare da camshaft, da K24Z da gyare-gyare ne m injuna. Idan an kiyaye shi da kyau kuma an zuba shi da mai tare da danko na 0W-20, kuma ana canza man shafawa sau ɗaya a kowace kilomita 5-6, to, zai yi aiki na dogon lokaci ba tare da wata matsala ba da buƙatar saka hannun jari a gyara. Gaskiya ne, dole ne ku saka hannun jari a cikin mai, amma wannan ba tsada bane kamar maye gurbin camshaft. Tare da ingantaccen kulawa, motar za ta “gudu” nisan kilomita dubu 300 kyauta. Wani wuri a kusa da 200 dubu, kawai dole ne ku maye gurbin sarkar lokaci - ya ƙare a lokacin, amma akwai lokuta lokacin da masu maye gurbin su bayan 300 dubu kilomita.
Wasu masu motoci sun yi imanin cewa bayan gudu na kilomita dubu 100 wajibi ne a yi amfani da man fetur mai mahimmanci - wannan ba daidai ba ne kuma zai iya haifar da lalacewa ga camshaft. Gaskiyar ita ce, tashoshin mai ta hanyar da ake isar da mai zuwa ga nodes ɗin da ake buƙata ba a saita su da faɗi ba, don haka bai kamata ku yi amfani da mai mai ɗanɗano ba bayan kilomita dubu 100. Dole ne a bi ƙaƙƙarfan shawarwarin masana'anta. Bugu da ƙari, a cikin takardar bayanan motar Honda, yana ba da cikakkun bayanai game da lokacin, yadda da kuma irin man da za a zuba.
Takaitaccen
Motocin K-jerin, gami da K24Z, ba sa son masu sana'a da yawa saboda gazawar camshaft akai-akai. Duk da haka, a gaskiya, idan an kula da motar da kyau, injin zai rayu na dogon lokaci.

Har ila yau, motar ta sami damar daidaitawa - gyare-gyare daban-daban na iya ƙara ƙarfin K24 na ciki na konewa zuwa 300 hp. Tuning Studios (Cokaka, Mugen) suna ba da kaya iri-iri don kammala waɗannan injunan - sun shahara ba kawai a tsakanin masu son ba, har ma da ƙwararru. A cikin wasu da'irori, injunan K-jerin na Honda ana ɗauka sun fi dacewa don kunnawa fiye da jerin B-series na almara. Koyaya, injunan B-jerin ba su sami irin wannan lahani ba kamar saurin lalacewa na camshaft.
Gabaɗaya, Honda K24Z da gyare-gyare sune injuna masu dogara tare da dogon albarkatu, amma suna buƙatar kulawa da dacewa da amfani da man fetur daidai.
