NA20P thiab NA20S Nissan cav
Txheem
Thoob plaws hauv nws keeb kwm ntev, Nissan tau tsim thiab tsim ntau yam khoom siv tsheb los ntawm nws cov kab sib dhos. Kev txhawj xeeb ntawm cov tshuab thiab lawv cov khoom tau txais kev lees paub zoo tshaj plaws thoob plaws ntiaj teb. Hnub no peb yuav tham txog qhov kawg. Yuav kom meej meej, peb yuav tham txog 2-liter units ntawm NA series sawv cev los ntawm NA20P thiab NA20S. Cov lus piav qhia ntawm txhua qhov sib txawv ntawm cov motors, lawv cov yam ntxwv thiab kev ua haujlwm tuaj yeem pom hauv qab no.
Lub tswv yim thiab keeb kwm ntawm kev tsim cov motors
Thaum pib ntawm lub 80s ntawm lub xyoo pua xeem, Nissan engineers ntsib ib tug loj thiab lub luag hauj lwm. Nws cov ntsiab lus yog los hloov cov kev coj ncaj ncees thiab technically tsis siv nyob rau hauv combustion xyaw ntawm Z series nrog ib yam dab tsi tshiab thiab tsis muaj tsawg zoo.
Txoj kev daws teeb meem no poob rau hauv ib nrab ntawm lub 80s, thaum nyob rau hauv 1989 lub motors ntawm NA kab txiav txim siab hnub no mus rau hauv serial ntau lawm. Tom ntej no, cia peb tham txog 2-liter cov neeg sawv cev ntawm koob. Lub cav 1,6-liter yuav suav tias yog lwm lub sijhawm.
Yog li, NA20s ntawm lub cav yog ob-liter fais fab nroj tsuag tsim los ntawm Nissan. Koj tuaj yeem ntsib lawv hauv ob qhov sib txawv:
- NA20S - roj av carburetor cav.
- NA20P yog ib chav roj uas siv los ntawm qhov tshwj xeeb txhaj tshuaj.
Sib nrug los ntawm hom recharge, qhov hloov pauv ntawm NA20s tsis txawv ntawm ib leeg. Txhua lub cav ntawm cov koob yog tsim los ntawm lub hauv paus ntawm ib qho txhuas thaiv thiab nws lub taub hau, nrog rau siv ib lub camshaft. Vim tias qhov kev tsim no, tsuas muaj 4 li qub rau txhua tus ntawm 2 lub tog raj kheej ntawm lub cav. Txias rau txhua tus neeg sawv cev ntawm koob yog kua.
Lub cav NA20S tau tsim los ntawm 1989 txog 1999. Chav tsev no tau nruab rau ntawm sedans ntawm Nissan kev txhawj xeeb. Nws tau siv dav tshaj plaws ntawm Cedric thiab Crew qauv.
NA20P tau tsim los ntawm tib lub xyoo thiab tseem yog. Lub tswv yim ntawm lub cav no tau ua tiav zoo heev uas nws tseem muaj peev xwm siv nyiaj loj-loj Japanese qauv. Feem ntau, cov roj NA20 tuaj yeem pom ntawm Nissan Truck, Atlas thiab Caravan.

Lub NA20 motors tau tsim tshwj xeeb hauv atmospheric variations nrog cov yam ntxwv qhia hauv lub rooj. Nws tsis tuaj yeem nrhiav lwm cov qauv ntawm NA20S thiab NA20P hauv Tshuag.
Kev Pabcuam thiab Kho
Motors "NA" tsis yog tsuas yog ua tiav rau Nissan ntawm cov nyiaj tau los ntawm lawv qhov muag, tab sis kuj zoo heev. Ob-liter cav ntawm kab tsis muaj qhov tshwj xeeb, yog li lawv tsuas muaj cov lus pom zoo los ntawm tag nrho lawv cov neeg siv khoom.
Tsis yog NA20S lossis NA20P tsis muaj qhov tsis raug. Nrog kev kho kom zoo thiab kev saib xyuas kom zoo, cov chav nyob hauv nqe lus nug tsis tshua tawg thiab ntau dua li rov qab lawv cov peev txheej ntawm 300 - 000 mais.
Yog tias qhov kev puas tsuaj ntawm NA20th tsis tuaj yeem zam tau, koj tuaj yeem thov rau kev kho nws ntawm qhov chaw pabcuam kiag li. Kev kho cov cav no, zoo li lwm yam los ntawm Nissan, yog ua los ntawm ntau lub khw kho tsheb, thiab teeb meem nrog nws tshwm sim tsis tshua muaj.
Tus tsim thiab lub tswv yim dav dav ntawm NA20S thiab NA20P yog qhov yooj yim me ntsis, yog li "kev coj lawv mus rau lub neej" tsis nyuaj. Nrog rau kev txawj ntse thiab kev paub dhau los, koj tuaj yeem kho tus kheej.
Raws li kev hloov kho tshiab ntawm NA20s, nws yog qhov ua tau. Txawm li cas los xij, nws tsis tsim nyog kho cov cav no tsawg kawg yog ob qho laj thawj:
- Ua ntej, nws yog inexpedient nyob rau hauv cov nqe lus ntawm cov nyiaj. Nws yuav ua tau kom nyem tawm ntawm lawv tsis ntau tshaj 120-130 horsepower, tab sis cov nuj nqis yuav tseem ceeb.
- Qhov thib ob, cov peev txheej yuav poob qis heev - txog li 50 feem pua ntawm cov muaj, uas tseem ua rau kev hloov kho tshiab tsis muaj txiaj ntsig.
Ntau tus neeg tsav tsheb nkag siab txog qhov tsis muaj txiaj ntsig ntawm kev txhim kho NA20S thiab NA20P, yog li lub ntsiab lus ntawm kev kho lawv tsis nyiam ntawm lawv. Ntau zaus, cov tswv ntawm cov motors no txaus siab rau qhov muaj peev xwm hloov tau.
Raws li kev xyaum qhia, qhov zoo tshaj plaws kev xaiv rau kev siv ntawm lub tom kawg yog yuav ib tug diesel cav los ntawm Nissan nrog lub npe "TD27" los yog nws turbo version "TD27t". Rau txhua tus qauv ntawm cov chaw tsim khoom, lawv haum zoo kawg nkaus, tau kawg - nyob rau hauv cov nqe lus ntawm kev hloov NA20s.
