Uchungechunge lwe-K24 luhlanganisa izinjini zesimanje zobuchwepheshe ezithole ukuguqulwa nezinguqulo ezahlukene. I-K24Z motors ingenye yochungechunge, oluhlanganisa ama-motor angu-7 anezinguquko ezincane zokuklama.
Ukuguqulwa
Izinjini ze-Honda K-series ezingu-2.4 litre zithathe indawo yenjini evuthayo yangaphakathi ye-F23. Basuselwe ezinjinini ezingu-2 litre K20. Ukuthi nje i-K24 isebenzisa ama-crankshaft ane-piston stroke enwetshiwe (99 mm vs 86 mm), ama-pistons ngokwawo anobubanzi obukhudlwana, i-cylinder block ehlukile kanye nezinduku ezintsha zokuxhuma zifakiwe lapha. Ikhanda lesilinda lifakwe isistimu ye-I-VTEC yokuphathelene; azikho izinxephezelo ze-hydraulic, ngakho-ke injini idinga ukulungiswa kwe-valve uma kunesidingo. Ngokuvamile isidingo sivela ngemva kwamakhilomitha ayizinkulungwane ezingu-40.
Njengoba kufanele noma iyiphi injini ephumelelayo (naphezu kokushiyeka kwayo, izinjini ze-K24 zibhekwa njengempumelelo), zathola ukuguqulwa okuhlukahlukene - A, Z, Y, W. Zonke zihlukile komunye nomunye ngokuklama, amandla, i-torque, isilinganiso sokucindezela.
Ikakhulukazi, uchungechunge lwe-Z lwaluhlanganisa amamotho ayi-7:
- I-K24Z1 iyi-analogue yenjini ye-K24A1, ukuguqulwa kokuqala kwenjini ye-K24. Lena injini yomlilo yangaphakathi esetshenziswa umphakathi enezigaba ezi-2 zokuthatha izinto eziningi, i-i-VTEC valve timing kanye nohlelo lwe-stroke ku-camshaft yokudonsa. Inomnotho futhi inokuqukethwe okuphansi kwezinto eziyingozi ekuphumeni. Isilinganiso sokucindezela - 9.7, amandla - 166 hp. ngo-5800 rpm; i-torque - 218 Nm. Le nguqulo isetshenziswa esizukulwaneni sesithathu i-CR-V. Yagcina ukufakwa ngo-3 futhi ayisasetshenziswa.
- I-K24Z2 - i-K24Z1 efanayo, kodwa ngama-camshaft ashintshiwe, isilinganiso sokucindezela 10.5. amandla anda afinyelela ku-177 hp. ku-6500 rpm, i-torque - 224 Nm ku-4300 rpm.
- I-K24Z3 – inguqulo enezinga eliphezulu lokucindezela (10.5).
- I-K24Z4 – i-K24Z1 efanayo.
- I-K24Z5 – i-K24Z2 efanayo, kodwa nge-181 hp.
- I-K24Z6 - ekwakhiweni kwayo iyinjini efanayo yangaphakathi evuthayo i-K24Z5, kodwa enamakhamera ahlukene.
- I-K24Z7 - le nguqulo ithole izinguquko zokuklama. Amanye ama-piston, ama-intake manifold nama-camshaft afakwe lapha. Uhlelo lwe-VTEC lusetshenziswa ku-5000 rpm. Amandla enjini adlule uphawu lwama-200 futhi afinyelela ku-205 hp. ngo-7000 rpm; i-torque - 230 hp ngo-4000 rpm. Injini isetshenziswa ezimotweni ezintsha zakwaHonda.
isithunzi
Lonke uchungechunge lwe-K luphawula ushintsho ezizukulwaneni nasezintweni ezibalulekile zeHonda. Ama-motor alolu chungechunge aqala ukuzungeza iwashi, idrayivu yathathelwa indawo yi-chain drive, futhi lezi zinjini zisebenzisa uhlelo olusha lwe-VTEC - iVTEC. Kukhona nezinye izixazululo nemibono yezobuchwepheshe. Sekuyiminyaka engaphezu kweshumi lezi zinjini zisetshenziswa ngempumelelo ezimotweni ezintsha zakwaHonda, ezingaphansi kwezidingo eziphezulu ngokwezemvelo nomnotho. Badla uphethiloli omncane, futhi i-exhaust iqukethe inani elincane lezinto eziyingozi emvelweni.
Okubaluleke kakhulu ukuthi ochwepheshe be-Honda bakwazi ukulinganisa izinjini, ukuhlinzeka nge-torque enamandla kakhulu namandla. Ukuguquguquka kwamapulatifomu nakho kuyinhlanganisela - injini ye-K24 ithole ukuguqulwa okuhlukahlukene okunezici ezishintshile, okwenza kube nokwenzeka ukuzisebenzisa ezimotweni ezahlukene.
Okuphawuleka kakhulu isistimu ye-iVTEC, elawula isikhathi futhi ikuvumela ukuthi uzuze ukusetshenziswa kophethiloli okuphelele. Ngisho izinjini ezingu-2.4-litre iVTEC zidla kancane uphethroli uma kunenjini yakudala engu-1.5 litre. Isistimu yazibonakalisa kahle uma isheshisa - izinjini ezinalolu buchwepheshe azizange zidlule amalitha angu-12-14/100 km ngesikhathi sokushayela kakhulu edolobheni, okuwumphumela omuhle kakhulu wenjini engu-2.4-litre.
Ngenxa yalezi zinzuzo, i-K series motors yaduma futhi yamukelwa kahle abathandi bezimoto, kodwa ngemva kwesikhathi esithile, izinkinga ezihlobene nokuthembeka komklamo zaqala ukuvela.
inkinga enkulu
Inkinga enkulu ngezinjini zochungechunge lwe-K (kuhlanganise nezinguqulo ezingu-2.4-litre) yi-exhaust camshafts. Ngesinye isikhathi baguga kakhulu futhi bamane bengakwazi ukuvula ama-valve e-exhaust ngendlela efanele. Ngokwemvelo, izinjini ezine-camshaft ezigugile azizange zisebenze kahle. Uphawu lwesici luyakhubeka; ngesikhathi esifanayo, ukusetshenziswa kukaphethiloli kunyukile kanye nesivinini sishintshashintsha. Lokhu kuphoqe abanikazi ukuthi balahle izimoto zabo ngemuva kokulungisa kuqala uphiko lukagesi. Abanye abazange balungise ngisho nokulungisa ngenxa yezindleko eziphakeme zezingxenye ezisele kanye nezinsizakalo zikamakhenikha - ngokwesilinganiso, izindleko eziphelele zokulungisa zazingamadola angama-700-800 aseMelika. Konke lokhu kwathuthukiswa yiqiniso lokuthi ngemva kokulungiswa nokushintsha i-camshaft yokukhipha, ngemva kwesikhathi esithile ngokusetshenziswa okujulile inkinga yavela futhi - nge-camshaft entsha.
Ngesikhathi sokulungiswa, akekho ongaqinisekisa ukuthi izingxenye ezintsha ezisele zizohlala isikhathi eside; ezimweni ezingavamile, lonke ikhanda le-cylinder lalidinga ukushintshwa, ngoba ngisho nombhede we-camshaft wawugqoke. Ngemuva kokuhlaziywa okujulile kwamacala ahlukahlukene, ochwepheshe bafinyelela esiphethweni sokuthi inkinga ibisohlelweni lokuhlinzeka nge-lubricant kuyunithi, kepha akekho owaziyo ukuthi yini engalungile ngayo. Kukhona inkolelo-mbono yokuthi inkinga ilele eziteshini zokuphakela i-lubricant emincane ku-camshaft, kodwa lokhu akuqinisekile.
Abanye ochwepheshe bathi i-Honda imane ibale ngokungalungile ukwakheka kwe-alloy ukuze kwakhiwe ama-camshafts, futhi izinguqulo zabekwa phambili mayelana nenqwaba yezingxenye ezisele ezinesici. Ngokusobala, i-Honda yaqala ukulawula kabi izinga lezingxenye ezisetshenzisiwe futhi yavumela amakhamera wekhwalithi ephansi ukuthi angene emgqeni womhlangano.
Izinkolelo-mbono zozungu nazo zikhona. Ngokusho kwabo, ochwepheshe bakwaHonda benza ngamabomu izingxenye ezinesevisi ephansi ukuze izimoto zilethwe eziteshini ezisemthethweni kaningi.
Iyiphi inguqulo elungile akwaziwa, kodwa iqiniso liwukuthi ama-camshaft amasha enziwa kusetshenziswa ubuchwepheshe obuhlukile. Ezinjinini ezindala ze-Honda zochungechunge lwe-D no-B, kwasetshenziswa ama-camshaft aqinile - ukuhlolwa kuqinisekisile lokhu. Uma le ngxenye yochungechunge lwenjini engu-B noma D ijikijelwa phansi kukakhonkolo, izohlukana ibe izingxenye ezimbalwa, kodwa i-camshaft evela ku-K injini izohlala injalo.
Qaphela ukuthi kwezinye izinjini zochungechunge lwe-K azikho izinkinga ezinjalo, kwamanye ama-camshafts kwakudingeka ashintshwe njalo ngamakhilomitha ayizinkulungwane ezingu-20-30. Ngokombono wezingcweti nabanikazi, inkinga yayivame ukuvela ezinjini lapho uwoyela we-viscous uthululelwa khona - 5W-50, 5W-40 noma 0W-40. Lokhu kwaholela esiphethweni sokuthi izinjini K-uchungechunge zidinga uwoyela mncane nge viscosity 0W-20, kodwa futhi lokhu akuzange kuqinisekise ukuphila isikhathi eside injini.
Ezinye izindaba
Inkinga engabalulekile kangako ukungasebenzi kahle kwe-solenoid kanye negiya le-VTC elibanga umsindo ongajwayelekile. Inkinga yokugcina yenzeka ezinjinini ze-K24 ezithuthukisiwe. Izimbangela eziqondile zalezi zinkinga azaziwa, kodwa kukhona izinsolo zokushintshwa kukawoyela okufika ngesikhathi. Ukuvula iyunithi kwenza kube nokwenzeka ukunquma ukuguga okukhulu okubangelwa indlala kawoyela; kuyaqabukela kutholakale ukuthi iyunithi igcwele uwoyela, okuvele kuphekwe ngesikhathi sokusebenza isikhathi eside.
Ezinye izinkinga "zakudala" nazo zikhona:
- Isivinini sokubhukuda - singaxazululwa ngokuhlanza i-throttle valve ne-IAC.
- Ukudlidliza - ezinjinini ezigugile, ibhande lesikhathi linganwebeka, okubangela ukudlidliza. Kuyelulekwa futhi ukuthi uhlole izigxivizo zenjini.
- Ukuvuza kukawoyela - ezikhathini eziningi inkinga iba ku-crankshaft oil seal yangaphambili. Ukuyishintsha kuzoxazulula le nkinga.
Yilapho izinkinga ziphela khona. Ngaphandle kodaba lwe-camshaft, i-K24Z nezinto eziphuma kuyo izinjini ezinokwethenjelwa. Uma uyigcina kahle futhi uthele amafutha nge-viscosity ye-0W-20, futhi ushintshe amafutha kanye njalo ngamakhilomitha ayizinkulungwane ezingu-5-6, khona-ke izosebenza isikhathi eside ngaphandle kwezinkinga kanye nesidingo sokutshala imali ekulungiseni. Yiqiniso, kuzodingeka utshale amafutha, kodwa akubizi njengokushintsha i-camshaft. Ngokulungiswa okufanele, injini izogijima ngokukhululeka amakhilomitha ayizinkulungwane ezingama-300+. Endaweni ethile ezungeze uphawu lwezinkulungwane ezingama-200, uzomane ushintshe uchungechunge lwesikhathi - ngaleso sikhathi luzoguga, kodwa kube khona izimo lapho abanikazi beshintsha khona ngemva kwe-300 km.
Abanye abanikazi bezimoto bakholelwa ukuthi ngemva kokushayela amakhilomitha ayizinkulungwane eziyi-100 kudingekile ukusebenzisa amafutha e-viscous ngaphezulu - lokhu akulungile futhi kungaholela ekulimazeni kwe-camshaft. Iqiniso liwukuthi iziteshi zikawoyela lapho i-lubricant ihanjiswa khona ezingxenyeni ezidingekayo azibanzi, ngakho-ke akufanelekile ukusebenzisa amafutha e-viscous ngaphezulu ngemva kwamakhilomitha ayizinkulungwane eziyi-100. Izincomo eziqinile zomenzi kufanele zilandelwe. Ngaphezu kwalokho, esitifiketini sokubhaliswa kwemoto, i-Honda inikeza iziqondiso ezicacile zokuthi nini, kanjani futhi hlobo luni lwamafutha okufanele luthelwe.
Isifingqo
Izimoto zochungechunge lwe-K, okuhlanganisa ne-K24Z, azithandwa omakhenikha abaningi ngenxa yokuhluleka kaningi kwe-camshaft. Kodwa-ke, empeleni, uma uyinakekela kahle injini yakho, injini yakho izohlala isikhathi eside. Udinga nje ukuqhela kunoma yisiphi iseluleko bese ulandela imithetho yesondlo. Ukugcinwa kwenjini yomlilo yangaphakathi kusezingeni eliphezulu - injini iyahlakazwa, ilungiswe futhi ihlanganiswe ngokushesha.
Injini futhi inamandla okushuna - ukuguqulwa okuhlukahlukene kungakhuphula amandla enjini yomlilo yangaphakathi ye-K24 aze afike ku-300 hp. Tuning Studios (Spoon, Mugen) zinikeza kits ahlukahlukene ukuze ulungise lezi izinjini - awaziwa kuphela nayizimfundamakhwela, kodwa futhi phakathi ochwepheshe. Kweminye imibuthano, kukholakala ukuthi uchungechunge lwe-K lwezinjini ze-Honda lufaneleka kangcono ukushuna kunochungechunge lwe-B oludumile. Kodwa-ke, izinjini ze-B-series azizange zihlupheke njengokungathi ukuguga okusheshayo kwe-camshaft.
Ngokuvamile, "Honda K24Z" kanye ukuguqulwa - izinjini onokwethenjelwa ukuphila isikhathi eside, kodwa zidinga kakhulu ukunakekelwa okufika ngesikhathi kanye nokusetshenziswa uwoyela kwesokudla.
