Hais txog Mazda K-series cav

K series los ntawm Mazda yog V-shaped engine nrog ib tug ntim ntawm 1,8 mus rau 2,5 litres.

Cov neeg tsim tawm ntawm cov kab ntawm cov cav no tau teeb tsa lawv tus kheej lub hom phiaj ntawm kev tsim lub zog hluav taws xob uas yuav ua kom muaj txiaj ntsig zoo, muab kev nrawm nrawm, muaj roj tsawg thiab ua tau raws li txhua qhov kev nyab xeeb ib puag ncig.

Tsis tas li ntawd, nws tau txiav txim siab los nruab K series cav nrog lub suab zoo nkauj uas piav txog lub zog tag nrho ntawm lub plawv ntawm lub tsheb.

Mazda K series cav tau tsim los ntawm 1991 txog 2002. Cov kab no suav nrog cov kev hloov kho hauv qab no ntawm cov motors:

1. K8;
2. KF;
3. KJ-KEV;
4. KL;

Txhua lub cav ntawm cov khoom nthuav tawm muaj V-zoo li tus tsim nrog lub tog raj kheej lub taub hau ntawm 60 degrees. Lub thaiv nws tus kheej yog ua los ntawm txhuas, thiab lub tog raj kheej taub hau nrog ob camshafts. K series xyaw raws li kev tsim qauv, raws li cov neeg tsim khoom, yuav tsum muaj qhov zoo hauv qab no:

1. Kev siv roj tsawg nrog tsawg emissions ntawm cov khoom tsis zoo rau hauv qhov chaw;
2. Zoo acceleration dynamics, nrog rau ib tug qab ntxiag engine suab;
3. Txawm tias muaj tseeb hais tias lawv muaj ib tug V-zoo li tus tsim nrog rau lub tog raj kheej, lub cav ntawm no series yuav tsum yog lub lightest thiab compact nyob rau hauv lawv cov chav kawm ntawv;
4. Muaj cov qib siab ntawm lub zog thiab durability txawm tias nyob rau hauv kev nce loads.

Hauv qab no yog Pentroof combustion chamber, uas yog nruab nrog tag nrho cov kab ntawm K series xyaw:

Kev hloov kho ntawm K series cav

K8 - yog lub zog tsawg tshaj plaws los ntawm cov koob no thiab tib lub sijhawm thawj lub cav uas tau teeb tsa ntawm lub tsheb tsim khoom. Cav muaj peev xwm yog 1,8 l (1845 cm³). Nws tsim muaj 4 li qub rau ib lub tog raj kheej, nrog rau cov hauv qab no:

1. DOHC yog ib qho system uas muaj ob lub camshafts nyob rau hauv lub tog raj kheej taub hau. Ib tug ncej yog lub luag hauj lwm rau kev khiav hauj lwm ntawm lub intake li qub, thiab lub thib ob rau lub tso li qub;
2. VRIS yog ib qho system uas hloov qhov ntev ntawm cov khoom siv manifold. Nws tso cai rau ntau optimized zog thiab torque thiab txhim kho roj efficiency.

Lub hauv paus ntsiab lus ua haujlwm ntawm VRIS system yog qhia hauv daim duab hauv qab no:

Ob qhov kev teeb tsa ntawm lub cav no tau tsim - Asmeskas (K8-DE), ua tau 130 hp. thiab Japanese (K8-ZE) nrog 135 hp.

KF- lub cav ntawm cov qauv no muaj qhov ntim ntawm 2,0 l (1995 cm³) thiab tau tso tawm ntau lub versions. Raws li ntau yam kev ntsuas fais fab, KF-DE version muaj los ntawm 140 txog 144 hp. Tab sis nws cov npoj yaig Nyij Pooj KF-ZE muaj 160-170 hp ntawm nws qhov chaw pov tseg.

KJ-ZEM - chav tsev fais fab no, nrog kev hloov pauv ntawm 2,3 liters, yog nyob rau hauv ib lub sij hawm suav hais tias yog ib qho ntawm cov tshiab tshaj plaws ntawm tag nrho cov cav los ntawm Mazda. Qhov no tshwm sim vim nws ua haujlwm raws li "Miller Cycle", lub ntsiab lus uas yog siv lub supercharger. Nws pab txhawb kom muaj txiaj ntsig compression piv, uas ua rau muaj zog ntau ntxiv ntawm no rau lub tog raj kheej V-twin cav. Lub supercharger nws tus kheej yog tsim nyob rau hauv daim ntawv ntawm ib tug ob-ntsia hlau system uas tswj lub boost. Tag nrho cov no tau tso cai rau lub cav, nrog kev hloov pauv ntawm 2,3 litres, tsim lub zog ntawm 217 hp thiab lub zog ntawm 280 N * m. KJ-ZEM tau raug suav nrog hauv cov npe ntawm cov tshuab zoo tshaj plaws rau xyoo 1995 - 1998.

KL - lub cav tsev neeg ntawm no series muaj ib tug ua hauj lwm ntim ntawm 2,5 litres (2497 cm³). Tsuas muaj peb qhov kev hloov pauv ntawm lub zog no - Japanese version KL-ZE, uas muaj 200 hp; American KL-DE, uas yog lub ntiaj teb version thiab muaj los ntawm 164 txog 174 hp. Tsis tas li ntawd, ib qho version ntawm KL-03 tau tsim tawm sab nraud Tebchaws Meskas, uas tau teeb tsa rau Ford Probes. Nws yog ib nqi sau cia hais tias nyob rau hauv 1998, ib tug txhim khu kev qha version ntawm lub KL, hu ua KL-G626, twb qhia nyob rau hauv lub Mazda 4. Lub tshuab nqus tsev tau raug hloov kho, lub cam khwb cia crankshaft tau siv los txo qhov kev sib hloov loj, thiab lub tshuab hluav taws xob los ntawm Ford EDIS tau siv thawj zaug.

Hauv qab no yog daim duab kos duab ntawm KL lub cav:

Rau siv! KL series ntawm cov cav tau nruab nrog VRIS system, uas cov neeg tsim khoom suav tias yog cov thev naus laus zis tseem ceeb tshaj plaws ntawm cov tiam tshiab. Nws cov ntsiab lus yog tias qhov ntim thiab qhov ntev ntawm lub resonance chamber nyob rau hauv lub pa manifold hloov ua tsaug rau rotary li qub. Qhov no ua rau nws ua tau kom ua tiav qhov zoo tshaj plaws piv ntawm lub zog thiab lub zog ntawm txhua lub cav ceev!

Cov Ntaos Ntaus

Rau cov ntaub ntawv ntau dua thiab yooj yim tshaj plaws, tag nrho cov yam ntxwv tseem ceeb tshaj plaws ntawm K series cav tsev neeg tau sau tseg hauv cov lus hauv qab no:

K8	KF	KJ-ZEM	KL

Nws tseem yuav tsum tau ntxiv tias cov peev txheej ntawm cov cav hauv K series txawv thiab nyob ntawm qhov ntim, nrog rau muaj lub turbocharger. Yog li, piv txwv li, kwv yees qhov peev txheej ntawm K8 qauv yuav yog 250-300 txhiab km. Lub neej ntev ntawm KF xyaw tuaj yeem ncav cuag 400 txhiab km, tab sis qhov xwm txheej nrog KJ-ZEM txawv me ntsis.

Lub cav no tau nruab nrog lub turbocharger, uas ua rau kom muaj zog ua haujlwm thaum ua rau nws muaj kev ntseeg siab. Yog li ntawd, nws cov mileage yog li 150-200 txhiab km. Yog hais tias peb tham txog KL cav, ces lawv lub neej kev pab mus txog 500 txhiab km.

Rau siv! Txhua lub cav muaj nws tus lej xov tooj, suav nrog K series los ntawm Mazda. Rau cov combustion engines nyob rau hauv tag nrho nws cov kev hloov kho, cov ntaub ntawv hais txog tus xov tooj yog muab tso rau ib tug tshwj xeeb platform, uas yog nyob rau sab xis ntawm lub engine, ze rau lub sump. Nws yuav tsum tau muab sau tseg hais tias lub cav serial tooj kuj yuav duplicated ntawm ib tug ntawm lub tog raj kheej taub hau, nyob rau hauv qab ntawm lub pem hauv ntej tus neeg nrog caij qhov rooj, nyob rau hauv lub windshield. Nws tag nrho yog nyob ntawm lub tsheb hom!

Cov tsheb uas K series cav tau nruab

Cov npe ntawm cov tsheb uas tau nruab nrog cov kab ntawm cov cav no tau sau tseg hauv cov lus hauv qab no:

K8	Mazda MX-3, Eunos 500
KF	Mazda Mx-6, Xedos 6, Xedos 9, Mazda 323f, Mazda 626, Eunos 800
KJ-ZEM	Mazda Millenia S, Eunos 800, Mazda Xedos 9

Qhov zoo thiab qhov tsis zoo ntawm K series cav

Piv nrog rau cov kab dhau los ntawm cov cav, cov koob no yog qhov txawv los ntawm ntau qhov kev tsim kho tshiab, uas suav nrog kev hloov pauv rau cov chav combustion, kev noj haus thiab tso pa tawm, kev tswj hluav taws xob, nce kev ntseeg siab thiab txo suab nrov.

Tsis tas li ntawd, cov neeg tsim khoom tau tswj hwm kom ua tiav cov kev ua kom nrawm nrawm nrog kev siv roj tsawg thiab qis emissions ntawm cov khoom tsis zoo rau hauv qhov chaw. Tej zaum tsuas yog qhov teeb meem tseem ceeb, xws li feem ntau V-twin xyaw, yog nce roj noj.

Nco ntsoov! Japanese cav, suav nrog cov los ntawm Mazda, yog qhov txawv ntawm lawv txoj kev ntseeg tau thiab kav ntev. Nrog rau kev saib xyuas raws sijhawm thiab xaiv cov khoom siv zoo rau lub cav, tus tswv yuav tsis tas yuav kho lub tsheb no!
