Honda L15A, L15B, L15C cav

Nrog rau kev qhia txog cov qauv ntawm cov qauv hluas tshaj plaws thiab cov phooj ywg Civic, Fit (Jazz) compact tsheb, Honda launched ib tsev neeg tshiab "L" petrol units, qhov loj tshaj plaws yog cov neeg sawv cev ntawm L15 kab. Lub cev muaj zog hloov qhov nrov D15, uas yog me ntsis loj me me.

Nyob rau hauv lub cav 1.5L no, Honda engineers siv 220mm siab txhuas BC, 89.4mm stroke crankshaft (26.15mm compression qhov siab) thiab 149mm ntev txuas rods.

Kaum rau-valve L15s tau nruab nrog VTEC system uas ua haujlwm ntawm 3400 rpm. Qhov kev ncua ntev manifold yog optimized rau kev ua haujlwm nruab nrab. Cov pa nrog EGR system yog ua los ntawm stainless hlau.

Muaj kev hloov pauv ntawm L15 nrog tus tswv ntawm i-DSi (ntse ntse dual sib txuas ignition) system nrog ob lub tswm ciab diagonally opposite ib leeg. Cov cav no tau tsim tshwj xeeb kom txuag tau roj thiab txo cov emissions, thiab tom qab Fit lawv tsiv mus rau lwm cov qauv ntawm Honda, tshwj xeeb tshaj yog Mobilio thiab Lub Nroog.

Ntxiv rau qhov tseeb tias muaj 8- thiab 16-valve L15s, lawv kuj muaj nrog ob qho tib si thiab ob lub camshafts. Qee qhov kev hloov kho ntawm lub cav no tau nruab nrog turbocharging, PGM-FI thiab i-VTEC system. Tsis tas li ntawd, Honda kuj muaj kev hloov pauv ntawm L15 lub cav - LEA thiab LEB.

Lub cav naj npawb yog nyob rau ntawm lub tog raj kheej thaiv nyob rau hauv qab txoj cai thaum saib los ntawm lub hood.

L15A ua

Ntawm cov kev hloov kho ntawm lub cav L15A (A1 thiab A2), nws tsim nyog hais txog L15A7 chav tsev nrog 2-theem i-VTEC system, serial ntau lawm uas tau pib hauv 2007. Lub L15A7 tau txais cov tshiab pistons thiab sib zog txuas rods, loj li qub thiab sib zog rockers, raws li zoo raws li ib tug kho cua txias system thiab txhim kho manifolds.

Lub 15-liter L1.5A tau nruab rau ntawm Fit, Mobilio, Tus khub thiab lwm yam qauv Honda.

Qhov zoo, qhov tsis zoo thiab kev ruaj ntseg ntawm L15A / B / C

Kev ntseeg siab ntawm 1.5-liter cav ntawm tsev neeg "L" yog nyob rau theem tsim nyog. Hauv cov chav no, txhua yam yog qhov yooj yim heev thiab lawv ua haujlwm yam tsis muaj teeb meem.

Tshaj:

• VTEC;
• i-DSI systems;
• PGM-FI;

Daim ntawv

• Kev kaw lus tsis raug kaw.
• Kev ruaj ntseg.

Ntawm cov cav nrog i-DSI system, tag nrho cov ntsaws ntsaws yuav tsum tau hloov raws li xav tau. Txwv tsis pub, txhua yam zoo li niaj zaus - kev saib xyuas raws sijhawm, kev siv cov khoom siv zoo thiab cov roj. Lub sijhawm sib txuas tsis tas yuav tsum muaj kev saib xyuas ntxiv, tshwj tsis yog kev kuaj pom lub sijhawm thaum lub sijhawm ua haujlwm tag nrho.

Txawm hais tias L15 tsis yog qhov zoo tshaj plaws ntawm kev tswj xyuas, tag nrho cov kev tsim qauv siv los ntawm Honda mechanics tso cai rau cov cav no kom muaj cov npoo loj ntawm kev nyab xeeb los tiv thaiv kev ua haujlwm ntau tshaj plaws.

Kev them nyiaj yug L15

Tuning engines ntawm lub L15 series yog ib tug heev dubious ua hauj lwm, vim hais tias niaj hnub no muaj ntau lub tsheb nrog ntau haib units, nrog rau cov uas nruab nrog ib tug turbine, tab sis yog hais tias koj xav ntxiv "nees" rau tib lub L15A, koj yuav tsum tau. chaw nres nkoj lub tog raj kheej lub taub hau, nruab ib lub txias kom tsawg, ib tug loj damper, ib tug manifold "4-2-1" thiab pem hauv ntej ntws. Ib zaug ntsia rau Honda's VTEC-enabled Greddy E-tswj qhov kawg sub-computer, 135 hp tuaj yeem ua tiav.

Turbo L15B

Honda cov tswv nrog lub turbocharged L15B7 tuaj yeem pom zoo kom ua cov nti tuning thiab yog li nce qhov nce mus rau 1.6 bar, uas thaum kawg yuav tso cai rau koj mus txog 200 "nees" ntawm lub log.

Lub kaw lus ntawm cov cua txias rau cov khoom noj khoom haus, pem hauv ntej intercooler, tuned pa system thiab "hlwb" ntawm Hondata yuav muab txog 215 hp.

Yog tias koj muab cov khoom siv turbo tso rau ntawm lub cav L15B lub cev muaj zog, koj tuaj yeem nce mus txog 200 hp, thiab qhov no yog qhov siab tshaj plaws uas cov khoom lag luam L15 tsis tu ncua tuav.

xaus

Lub L15 series cav tsis tuaj ntawm lub sijhawm zoo tshaj plaws rau Honda. Thaum lub sij hawm tig ntawm lub xyoo pua, Japanese automaker pom nws tus kheej nyob rau hauv stagnation, txij li thaum lub structurally zoo meej, qub hwj chim units yog tsis yooj yim sua kom dhau los ntawm ib tug technical point ntawm view. Txawm li cas los xij, lub tuam txhab cov neeg siv khoom muaj peev xwm xav tau kev tsim kho tshiab, uas tau muab ntau los ntawm cov neeg sib tw. Thiab Honda tau txais kev cawmdim tsuas yog los ntawm cov hits xws li CR-V, HR-V thiab Civic, pib xav txog ib tiam tshiab ntawm subcompacts. Tias yog vim li cas thiaj li muaj tsev neeg dav dav ntawm L-engines, uas yog thawj zaug xeeb rau tus qauv Fit tshiab, cov ceg txheem ntseeg muag tau siab heev.

L-motors tuaj yeem raug suav hais tias yog ib qho ntawm feem ntau nrhiav tom qab hauv keeb kwm ntawm Honda. Tau kawg, los ntawm qhov pom ntawm kev saib xyuas, cov cav no tseem ceeb heev rau cov nroj tsuag hluav taws xob ntawm lub xyoo pua xeem, txawm li cas los xij, muaj teeb meem tsawg dua nrog lawv.

Qhov zaus ntawm kev teem sijhawm txij nkawm thiab kev ua siab ntev ntawm L-series kuj tseem qis dua "cov txiv neej laus" xws li cov neeg sawv cev ntawm D- thiab B-kab, tab sis ua ntej cov chav nyob tsis tas yuav tsum ua raws li ntau qhov chaw ib puag ncig. cov qauv thiab kev lag luam.
