Bosch DLLA157P649 Injector Nozzle - Txiav DN_PD Uas Lub Zog Mitsubishi Diesels

Hauv lub ntiaj teb kev txhaj tshuaj diesel, cov lej feem ntau tsis tshua muaj qhov sib txawv. Lawv yog iblus- ib tug compact code uas qhia rau ib tug kawm qhov muag txhua yam hais txog lub Cheebtsam lub geometry, ntws yam ntxwv, thiab npaj daim ntawv thov. CovBosch DLLA157P649yog ib qho piv txwv zoo meej.

Qhov no tsis yog ib lub nozzle xwb. Nws yog ibspecification encoded nyob rau hauv number case- DN_PD series nozzle uas tau tsav Mitsubishi diesel xyaw thoob plaws teb chaws, los ntawm lub teeb coj mus muag tsheb mus rau hnyav - tsheb thauj khoom. Txhua tus cwj pwm hauv "DLLA157P649" yog lub ntsiab lus: tsev neeg lub taub hau, lub kaum sab xis, tus nqi ntws, hom tuav. Thiab kev nkag siab cov lus ntawd yog thawj kauj ruam kom nkag siab tias yog vim li cas lub nozzle tseem ceeb.

 

 

Bosch's nozzle numbering system yog alegacy ntawm precision- tus qauv code uas tau muaj sia nyob ntau xyoo ntawm kev hloov pauv thev naus laus zis.

Ua txhaum DLLA157P649 :

Code Element	Lub ntsiab lus
D	D=DN nozzle tsev neeg (tus qauv nozzle tsim)
LL	LL=Ntev di ncauj / ntev protrusion nozzle tsim
A	A=Ib qho tshwj xeeb nozzle geometry variant
157	Spray angle:157 degrees- lub kaum sab xis uas cov roj tau txhaj rau hauv lub combustion chamber
P	P=P- hom nozzle (tus qauv muaj nozzle hom)
649	Flow rate / calibration code - txheeb xyuas cov yam ntxwv tshwj xeeb ntawm cov roj xa khoom

Qhov no qhia koj li cas:

Lub nozzle xa ib157-degree tsuag lub kaum sab xis- optimized rau tej piston tais geometry

Nws yog ibdaim di ncauj ntev tsim- qhov ntev protrusion yog sib npaug rau lub tog raj kheej taub hau lub taub hau lub taub hau

Cov649 flow codetxhais tau hais tias lub nozzle yog calibrated rau ib tug tshwj xeeb engine daim ntawv thov cov roj xa khoom yuav tsum tau

Kev sib txuas ntawm Denso: Lub DLLA157P649 kuj raug txheeb xyuas los ntawm tus lej Denso093400-6490. Qhov kev siv tus lej thib ob no muaj nyob hauv kev lag luam diesel qhov chaw - Bosch thiab Denso feem ntau tsim tus ntoo khaub lig- cov nozzles sib xws rau tib daim ntawv thov.

DLLA157P649 yog tsim los tiv thaiv cov xwm txheej huab cua ntawm diesel combustion:

Specification	Paub meej
Cov naj npawb	DLLA157P649 / 093400-6490
Hom Nozzle	DN_PD series, P- hom
Khoom siv	W6Mo5Cr4V2 (High Speed ​​Steel) / 18CrNi8
Hardness	HRC 62-65
Qhov hnyav	0, 04kg
Khoom siv lub cev	Hlau
Daim ntawv pov thawj	ISO9001
Warranty	Reflects manufacturers tus qauv zoo

Material science tseem ceeb: CovW6Mo5Cr4V2yog lub siab -ceev steel paub rau nwstshwj xeeb hnav tsis kamthiab muaj peev xwm tswj tau hardness ntawm siab kub. Cov18 Nc8yog ib rooj plaub-cov hlau tawv tawv uas muab cov tub ntxhais tawv tawv nrog hnav- tiv taus nto. Kev sib xyaw ua ke xa cov kav ntev uas yuav tsum tau ua rau siab -kev txhaj tshuaj diesel.

Nqus hardening- lub nozzle tau dhau lub tshuab nqus tsev kom ua tiav qhov tawv tawv ntawmHRC 62-65. Cov txheej txheem no tshem tawm cov oxidation ntawm qhov chaw thiab ua kom muaj kev sib haum xeeb ntawm cov khoom, qhov tseem ceeb rau qhov kev sib khi ntawm qhov chaw uas txhais tau tias qhov kev ua haujlwm ntawm lub tshuab nozzle.

 

 

Lub DLLA157P649 belongs rau lubP-hom nozzle tsev neeg- ib qho ntawm ntau hom nozzle siv dav hauv kev txhaj tshuaj diesel . P- hom nozzles yog tus cwj pwm los ntawm:

Standardized qhov ntev- interchangeable hla ntau lub tuam txhab

Pov thawj ntseeg- billions ntawm cov sij hawm ua hauj lwm nyob rau ntau xyoo ntawm kev siv

Teb- pabcuam tau- tuaj yeem kuaj thiab hloov nrog cov khoom siv yooj yim

Tus nqi- zoo- kev tsim khoom yooj yim dua li cov kab tsheb ciav hlau

Lub P- hom nozzle yog rau kev txhaj tshuaj diesel dab tsi lub qhov hluav taws xob yog rau roj av cav- ib qho kev sib xyaw ua ke uas tau ua kom zoo rau ze rau - zoo meej los ntawm ntau xyoo ntawm kev txhim kho txuas ntxiv.

 

 

DLLA157P649 ua haujlwm hauvob qho tib si mechanical thiab common rail txhaj tshuab. Thaum lub nozzle nws tus kheej yog ib tug neeg kho tshuab Cheebtsam - qhib thaum roj siab tshaj lub caij nplooj ntoos hlav nro thiab kaw thaum lub siab poob - nws yog siv nyob rau hauv cov cav nrog cov kev tsheb ciav hlau roj systems.

Nyob rau hauv ib tug general rail system:

Roj yog pressurized los ntawm lub siab - lub twj tso kua mis siab thiab khaws cia nyob rau hauv lub common rail accumulator

ECU txiav txim lub sijhawm txhaj tshuaj thiab lub sijhawm

Lub injector solenoid qhib kom tso siab rau - roj siab kom ncav cuag lub nozzle

Lub DLLA157P649 atomizes cov roj rau hauv cov huab cua zoo rau combustion

Lub nozzle lub luag hauj lwm tsis hloovTxawm hais tias lub kaw lus yog cov neeg kho tshuab lossis cov tsheb ciav hlau: nws hloov pauv siab - cov roj ua kua roj rau hauv cov tshuaj zoo atomized uas sib xyaw nrog cov cua compressed kom tiav combustion.

 

 

Nozzles yog cov khoom siv hnav. Lub koob thiab nozzle lub cev poob lawv precision haum. Cov qauv tshuaj tsuag degrades. Qhov qhib siab drifts.

Cov cim qhia tias DLLA157P649 xav tau kev hloov pauv:

Pib nyuaj- lub cav cranks tab sis ua tsis tiav

Poob zog- lub tsheb sib tw hauv qab load

Rough idle los yog misfire- combustion tsis sib xws

Cov pa luam yeeb ntau dhau- cov pa luam yeeb dub qhia tias muaj atomization tsis zoo

Kev siv roj ntau ntxiv- lub cav hlawv roj ntau dua rau tib txoj haujlwm

Kev kuaj mob: Nozzles tuaj yeem kuaj nrog anozzle testeruas siv lub siab thiab tso cai rau pom kev soj ntsuam ntawm cov qauv tshuaj tsuag. Yog tias cov qauv tshuaj tsuag tsis sib npaug lossis qhov qhib siab tsis raug, lub nozzle xav tau hloov.

 

 

Q1: Lub cav twg siv DLLA157P649?
Nws yog siv nyob rau hauvMitsubishi diesel xyawsuav nrog6D14, 6D14T, 6D15, 4D31A, S4F, S6F-T, 8DC8, 8DC81, 8DC9, 8DC91, thiab 8DC10. Cov ntawv thov suav nrog Volvo FH12 tsheb thauj khoom thiab Peugeot Partner tsheb lag luam.

Q2: Qhov txawv ntawm DLLA157P649 thiab 093400-6490 yog dab tsi?
Lawv yog tib lub nozzle.DLLA157P649 yog tus naj npawb Bosch nozzle; 093400-6490 yog tus naj npawb Denso. Ob leeg xa mus rau qhov zoo ib yam.

Q3: Cov khoom siv dab tsi yog DLLA157P649 ua los ntawm?
Lub nozzle yog tsim los ntawmW6Mo5Cr4V2 siab- ceev steelthiab18CrNi8 cov ntaub ntawv- hardening steel, nrog ib tug deg hardness ntawmHRC 62-65ua tiav los ntawm lub tshuab nqus tsev hardening.

Q4: Kuv puas tuaj yeem hloov lub nozzle xwb, lossis kuv puas xav tau lub tshuab ua tiav?
Kojtuaj yeem hloov lub nozzle xwb- nws yog ib qho khoom siv tau. Txawm li cas los xij, kev hloov lub nozzle yuav tsum tau muab tshem tawm kom zoo, tu, thiab calibration ntawm lub injector. Yog hais tias lub injector muaj cov sij hawm siab, kev kho kom tiav yog pom zoo.

Q5: Dab tsi yog qhov lav ntawm nozzle?
Lub nozzle los nrog lub warranty uas qhia txog cov chaw tsim khoom cov qauv zoo.
