K24 series suav nrog cov tshuab thev naus laus zis niaj hnub uas tau txais ntau yam kev hloov kho thiab cov qauv. Motors K24Z - ib qho ntawm cov koob, uas suav nrog 7 lub cav nrog kev hloov me me.
Kev hloov kho
Lub 2.4-liter Honda K-series xyaw hloov F23 ICE. Lawv ua raws li 2-liter K20 cav. Nws tsuas yog hais tias K24 siv crankshafts nrog kev ncua piston stroke (99 hli piv rau 86 hli), cov pistons lawv tus kheej muaj txoj kab uas hla loj dua, lub tog raj kheej sib txawv, cov hlua txuas tshiab tau teeb tsa ntawm no. Lub tog raj kheej lub taub hau yog nruab nrog ib tug proprietary I-VTEC system, tsis muaj hydraulic lifters, yog li lub cev muaj zog yuav tsum tau hloov valve yog tias tsim nyog. Feem ntau qhov xav tau tshwm sim tom qab 40 txhiab kilometers.
Raws li befits ib tug muaj kev vam meej lub cev muaj zog (txawm hais tias lub shortcomings, K24 engine yog xam tau tias yog kev vam meej), nws tau txais kev hloov pauv txawv - A, Z, Y, W. Lawv txhua tus sib txawv ntawm ib leeg, lub zog, torque, compression piv.
Hauv particular, 7 motors mus rau hauv Z series:
- K24Z1 yog ib qho analogue ntawm K24A1 lub cav, uas yog thawj qhov kev hloov kho ntawm lub cav K24. Qhov no yog ib tug pej xeem nyob rau hauv combustion engine nrog ib tug 2-theem intake manifold, ib tug i-VTEC valve lub sij hawm thiab mob stroke system ntawm lub intake camshaft. Nws yog kev lag luam thiab muaj cov ntsiab lus tsawg ntawm cov khoom tsis zoo hauv cov pa. Compression piv - 9.7, lub zog - 166 hp. ntawm 5800 rpm; torque - 218 Nm. Qhov no version yog siv rau 3rd tiam CR-V. Nws yog qhov kawg ntsia hauv 2012 thiab tsis siv lawm.
- K24Z2 - tib yam K24Z1, tab sis nrog hloov camshafts, compression piv 10.5. lub zog nce mus rau 177 hp. ntawm 6500 rpm, torque - 224 Nm ntawm 4300 rpm.
- K24Z3 - version nrog ntau dua compression piv (10.5).
- K24Z4 yog tib yam K24Z1.
- K24Z5 - tib yam K24Z2, tab sis nrog lub zog ntawm 181 hp.
- K24Z6 - los ntawm kev tsim nws yog tib yam ICE K24Z5, tab sis nrog sib txawv camshafts.
- K24Z7 - qhov no version tau txais kev hloov pauv tsim. Lwm cov pistons, intake manifold thiab camshafts yog ntsia ntawm no. VTEC system yog siv ntawm 5000 rpm. Lub cav fais fab tau tshaj 200 cim thiab mus txog 205 hp. ntawm 7000 rpm; torque - 230 hp ntawm 4000 rpm. Lub cev muaj zog yog siv rau ntawm cov tsheb tshiab Honda.
Zoo
Tag nrho K series cim kev hloov pauv hauv tiam neeg thiab qhov tseem ceeb rau Honda. Cov motors ntawm no series pib tig clockwise, tsav ntawm no tau hloov nrog ib tug saw, thiab lub tshiab VTEC system - iVTEC kuj siv nyob rau hauv cov motors. Muaj lwm yam kev daws teeb meem thiab cov tswv yim. Tau ntau tshaj kaum xyoo, cov cav no tau ua tiav zoo ntawm cov tsheb tshiab Honda, uas yuav tsum tau ua raws li kev xav tau ntawm ecology thiab kev lag luam. Lawv haus cov roj av me me, thiab cov pa muaj me me ntawm cov khoom tsis zoo ib puag ncig.
Qhov tseem ceeb tshaj plaws, cov kws tshaj lij Honda tswj kom sib npaug ntawm cov motors, muab lub zog zoo thiab lub zog. Lub versatility ntawm platforms kuj yog ib tug ntxiv - lub cav K24 tau txais ntau yam kev hloov kho nrog hloov cov yam ntxwv, uas ua rau nws muaj peev xwm siv lawv nyob rau hauv txawv tsheb.
Tshwj xeeb tshaj yog tsim nyog yog lub iVTEC system, uas tswj lub sij hawm ntawm lub sij hawm thiab tso cai rau koj mus cuag tau zoo roj noj. Txawm tias 2.4-litre iVTEC cav siv roj av me ntsis dua li yav dhau los tiam 1.5-litre cav. Lub kaw lus pom nws tus kheej zoo kawg nkaus thaum khaws ceev - cov cav nrog cov thev naus laus zis no tsis dhau 12-14 liters / 100 km thaum tsav tsheb hauv nroog, uas yog qhov txiaj ntsig zoo rau lub cav 2.4-liter.
Vim tias cov txiaj ntsig zoo no, K-series motors tau nrov thiab tau txais txiaj ntsig zoo los ntawm cov neeg tsav tsheb, tab sis tom qab qee lub sij hawm teeb meem pib tshwm sim cuam tshuam nrog kev ntseeg siab ntawm tus tsim.
qhov teeb meem loj
Qhov teeb meem loj tshaj plaws nrog K-series cov cav (xws li 2.4-liter versions) yog cov camshafts. Qee lub sij hawm, lawv hnav tawm ntau heev thiab tsuas yog tsis tuaj yeem qhib lub qhov tso pa tawm kom raug. Lawm, cav nrog ib tug hnav camshaft tsis ua hauj lwm kom raug. Ib tug yam ntxwv tsos mob yog tripling, nyob rau hauv parallel, noj roj av nce, thiab ua luam dej ceev tau pom. Qhov no yuam cov tswv kom tshem tawm cov tsheb, yav tas los kho lub hwj chim chav tsev. Qee qhov tseem tsis tau ua kev kho mob vim yog tus nqi siab ntawm cov khoom siv thiab cov kev pabcuam ntawm cov kws kho tsheb - qhov nruab nrab, tag nrho cov nqi kho yog 700-800 US las. Qhov no yog tag nrho cov aggravated los ntawm qhov tseeb hais tias tom qab kho thiab hloov lub tso camshaft, tom qab ib co sij hawm nrog intensive kev siv, qhov teeb meem tshwm sim dua - twb nrog ib tug tshiab camshaft.
Thaum lub sij hawm kho, tsis muaj leej twg tuaj yeem lav tias cov khoom tshiab yuav siv sij hawm ntev, nyob rau hauv tsawg zaus, tag nrho lub tog raj kheej taub hau yuav tsum tau hloov, txij li txawm lub camshaft txaj yuav tsum hnav. Tom qab kev tshuaj xyuas nruj ntawm ntau qhov xwm txheej, cov kws tshaj lij tuaj yeem txiav txim siab tias qhov teeb meem yog nyob rau hauv cov khoom siv roj nplua nyeem rau lub rooj sib txoos, tab sis qhov tseeb yog qhov tsis ncaj ncees lawm - tsis muaj leej twg paub. Muaj ib txoj kev xav hais tias qhov teeb meem nyob rau hauv txoj kab nqaim ntawm lubricant mov rau lub camshaft, tab sis qhov no tsis yog qhov tseeb.
Qee cov kws tshaj lij tau sib cav tias Honda tsuas yog xam qhov sib xyaw ntawm cov hlau rau kev tsim cov camshafts, thiab cov qauv tau muab tso rau pem hauv ntej hais txog cov khoom loj loj ntawm cov khoom seem. Allegedly, Honda pib tswj tsis zoo ntawm cov khoom siv thiab tso cai rau cov camshafts uas tsis zoo nkag mus rau hauv lub conveyor.
Conspiracy theories kuj muaj. Raws li lawv, cov kws tshaj lij Honda txhob txwm tshaj tawm cov khoom siv nrog cov peev txheej qis kom cov tsheb raug coj mus rau cov chaw pabcuam raug cai ntau dua.
Qhov twg yog qhov tseeb tsis paub, tab sis qhov tseeb yog tias cov camshafts tshiab tau tsim los siv cov cuab yeej sib txawv. Ntawm cov qub "Honda" motors ntawm D thiab B series, hardened camshafts tau siv - kev sim tau lees paub qhov no. Yog tias qhov no los ntawm B lossis D series cav raug muab pov rau hauv pem teb pob zeb, nws yuav tawg ua ob peb daim, tab sis lub camshaft los ntawm K lub cav yuav nyob twj ywm.
Nco ntsoov tias ntawm qee lub cav K-series tsis muaj teeb meem zoo li no, ntawm lwm tus camshafts yuav tsum tau hloov txhua txhua 20-30 txhiab kilometers. Raws li kev soj ntsuam ntawm cov kws tsim khoom thiab cov tswv, qhov teeb meem feem ntau tshwm sim ntawm cov cav uas tau ntim cov roj khov - 5W-50, 5W-40 lossis 0W-40. Qhov no coj mus rau qhov xaus tias K-series motors xav tau cov roj nyias nyias nrog viscosity ntawm 0W-20, tab sis qhov no kuj tsis tau lees tias lub cav lub neej ntev.
Lwm yam teeb meem
Ib qho teeb meem tsawg dua yog lub solenoid ua haujlwm tsis zoo thiab qhov txawv txav ntawm VTC iav. Qhov teeb meem kawg tshwm sim ntawm K24 lub cav nrog kev txhawb nqa. Qhov laj thawj tiag tiag ntawm cov teeb meem no tsis paub, tab sis muaj qhov tsis txaus ntseeg ntawm kev hloov roj tsis raws sijhawm. Qhib lub rooj sib txoos tso cai rau koj los txiav txim siab qhov hnyav hnyav tshwm sim los ntawm kev tshaib plab roj, clogging ntawm lub rooj sib txoos nrog cov roj tsis tshua pom, uas tau coked corny thaum lub sijhawm ua haujlwm ntev.
Lwm cov teeb meem "classic" kuj muaj:
- Kev ua luam dej nrawm - tuaj yeem daws tau los ntawm kev ntxuav lub throttle valve thiab IAC.
- Kev vibration - ntawm lub cev muaj zog, lub sij hawm siv yuav ncab, uas ua rau muaj kev vibration. Nws tseem pom zoo kom kuaj xyuas lub cav mounts.
- Roj xau - feem ntau qhov teeb meem nyob rau hauv pem hauv ntej crankshaft roj foob. Hloov nws yuav daws tau qhov teeb meem no.
Qhov no yog qhov teeb meem xaus. Yog tias koj tsis suav nrog qhov teeb meem nrog lub camshaft, ces K24Z thiab nws cov kev hloov kho yog lub cav txhim khu kev qha. Yog tias nws raug tswj xyuas kom zoo thiab nchuav nrog cov roj viscosity ntawm 0W-20, thiab cov roj nplua nyeem hloov ib zaug txhua 5-6 txhiab kilometers, ces nws yuav ua haujlwm ntev heev yam tsis muaj teeb meem thiab yuav tsum tau nqis peev hauv kev kho. Muaj tseeb, koj yuav tau nqis peev rau cov roj, tab sis qhov no tsis yog kim li hloov lub camshaft. Nrog kev saib xyuas kom raug, lub cev muaj zog yuav "khiav" 300+ txhiab kilometers. Qee qhov ntawm ib ncig ntawm 200 txhiab, koj tsuas yog yuav tsum tau hloov cov saw hlau lub sijhawm - nws hnav los ntawm lub sijhawm ntawd, tab sis muaj cov xwm txheej thaum cov tswv hloov nws tom qab 300 txhiab km.
Qee tus tswv tsheb ntseeg tias tom qab kev khiav ntawm 100 txhiab kilometers nws yog ib qho tsim nyog yuav tsum tau siv cov roj viscous ntau dua - qhov no tsis yog lawm thiab tuaj yeem ua rau muaj kev puas tsuaj rau lub camshaft. Qhov tseeb yog tias cov roj raws los ntawm cov roj nplua nyeem xa mus rau qhov tsim nyog cov nodes tsis tau teeb tsa dav dua, yog li koj yuav tsum tsis txhob siv roj ntau dua tom qab 100 txhiab kilometers. Cov neeg tsim khoom nruj me ntsis cov lus pom zoo yuav tsum ua raws. Ntxiv mus, nyob rau hauv daim ntawv teev cov ntaub ntawv rau lub tsheb Honda, nws muab cov lus qhia meej txog thaum twg, yuav ua li cas thiab hom roj npaum li cas.
Txoj kev xaus
K-series tsheb, suav nrog K24Z, tsis nyiam los ntawm ntau tus kws tsim khoom vim qhov tsis ua haujlwm camshaft tsis tu ncua. Txawm li cas los xij, hauv kev muaj tiag, yog tias lub cev muaj zog tau saib xyuas kom zoo, lub cav yuav nyob ntev. Koj tsuas yog yuav tsum tau rov qab los ntawm ib qho lus qhia thiab ua raws li cov cai tswj kev pabcuam. Kev tswj xyuas ntawm lub cav combustion yog nyob rau theem siab - lub cav yog disassembled, kho thiab sib dhos sai.
Tsis tas li ntawd, lub cev muaj zog tau txais lub peev xwm rau kev hloov kho - ntau yam kev hloov kho tuaj yeem ua rau lub zog ntawm K24 sab hauv combustion engine rau 300 hp. Tuning studios (Dawb, Mugen) muab ntau yam khoom siv rau kev ua tiav cov cav no - lawv nyiam tsis yog cov neeg nyiam ua haujlwm xwb, tab sis kuj yog cov kws tshaj lij. Hauv qee lub voj voog, Honda's K-series xyaw yog suav tias yog qhov zoo dua rau kev kho dua li cov lus dab neeg B-series. Txawm li cas los xij, cov tshuab B-series tsis tau txais qhov tsis zoo li qhov hnav ntawm lub camshaft ceev.
Feem ntau, Honda K24Z thiab kev hloov kho yog lub cav txhim khu kev qha nrog cov peev txheej ntev, tab sis lawv xav tau kev saib xyuas raws sijhawm thiab siv cov roj kom raug.
