QHOV TSEEB: Cav Mitsubishi 4D56
PRODUCT INTRODUCTION
Lub 2.5-liter Mitsubishi 4D56 diesel cav tau sib sau ua ke los ntawm kev txhawj xeeb los ntawm 1986 txog 2016 thiab tau nruab rau Pajero thiab Pajero Sport SUVs, L200 pickups thiab Delica minibuses. Lub hwj chim chav tsev no tau ua lub hauv paus rau lub npe nrov Hyundai D4BA, D4BF thiab D4BH diesel xyaw.
Lub cav 4D56 tau tsim nyob rau hauv 1986 los ntawm Japanese tsheb tuam txhab Mitsubishi. Tom qab ntawd, rau 10 xyoo, Japanese engineers tau ua tiav nws. Lub luag haujlwm tseem ceeb rau cov neeg tsim qauv yog txhawm rau txhim kho lub zog thiab kev pabcuam lub neej, kom muaj kev ruaj ntseg zoo.
4D56 yog tsim raws li tus qauv layout, lub tog raj kheej taub hau yog ua los ntawm txhuas thiab thaiv yog ua los ntawm cam khwb cia hlau. Nws yog kev siv cov alloys uas ua rau nws muaj peev xwm ua tiav qhov loj tshaj plaws thiab muab thermal stability zoo. Nyob rau hauv 2001, zus tau tej cov 4D56 nrog ib tug Common Rail roj system pib. Cov pistons tshiab tau siv, uas txo qhov compression piv rau 17. Tag nrho cov no tso cai rau kom muaj zog thiab torque.
4D5 tsev neeg kuj muaj xws li cav: 4D55.
Lub cav tau nruab rau:
Mitsubishi Delica 3 (P03) xyoo 1986 – 1999; Delica 4 (PA4) xyoo 1994 – 2007;
Mitsubishi L200 2 (K10) xyoo 1986 - 1996; L200 3 (K70) xyoo 1996 – 2006; L200 4 (KB) xyoo 2006 – 2016;
Mitsubishi Pajero 1 (L040) xyoo 1986 - 1991; Pajero 2 (V30) 1990 – 2000; Pajero 3 (V70) 1999-2006;
Mitsubishi Pajero Sport 1 (K90) xyoo 1996 - 2008; Pajero Sport 2 (KH) 2008-2016.

Qhov tsis zoo ntawm lub cav Mitsubishi 4D56
Chav tsev diesel no ntshai ntawm overheating thiab lub tog raj kheej taub hau gasket tawg tsis tu ncua. Tab sis hloov lub gasket tsis txaus, koj yuav tau zom cov mating nto. Tom qab ob peb qhov kev puas tsuaj, cov kab nrib pleb feem ntau tuaj yeem pom nyob ze li qub lossis prechambers.
Lwm qhov teeb meem loj ntawm lub cav no yog qhov tawg ntawm lub crankshaft, thiab qhov no tshwm sim tshwj xeeb tshaj yog thaum lub sijhawm txav mus ntev ntawm lub cav qis. Hauv cov cav nrog Common Rail system, cov ntawv xov xwm crankshaft yog tuab dua thiab kev tawg yog tsawg dua.
Rau cov laj thawj pom tseeb, cov roj hluav taws xob xa cov teeb meem ntau rau cov tswv ntawm xws li diesel xyaw, thiab qhov no siv rau ob lub vortex chamber thiab Common Rail versions.
Lub sijhawm siv sijhawm tsis muaj peev txheej loj thiab tsis tas yuav tsum tau khiav 90,000 km, tshwj xeeb tshaj yog tias koj tsis nruj nws txhua 30,000 km. Nrog kev so, nws tsuas yog tawg tawm ntawm lub rocker, tab sis nyob rau hauv lub Common Rail version ntawm lub cav, nws feem ntau rub tawm lub mounting bolts ntawm camshaft yokes. Thaum lub sij hawm sib npaug ntawm txoj siv sia, nws feem ntau poob rau hauv txoj siv sij hawm thiab ua rau nws tawg.
Tsis tas li ntawd, cov roj xau muaj nyob ntawm no, yuav luag tag nrho cov gaskets thiab cov ntsaws ruaj ruaj hws, lub crankshaft pulley thiab lub tshuab nqus tsev twj tso kua mis muaj cov peev txheej tsawg, EGR valve clogs, ntau yam teeb meem cuam tshuam nrog airing, thiab pistons tawg ntawm qhov me me. Thiab tsis txhob hnov qab xyuas lub valve tshem tawm txhua 20,000 km lossis lawv tsuas yog hlawv tawm.
