Bosch 1805344 Common Rail Injector: Lub Cav Nres Tus Saib Xyuas - Silencing Phantom Combustion Pulse Uas Defeats Scania's Retarder ntawm 12% Qhov Coob

Nyob rau hauv lub ntiaj teb no ntawm hnyav-haul Scania tsheb thauj khoom, cav braking tsis yog ib qho kev pab yooj yim - nws yog thawj kab ntawm kev tiv thaiv ntawm ib tug 60-tonne tag nrho ua ke pawg thiab ib tug khiav tawm qhovntsej thiaj tsis mob. Thaum cov pa nres nres thiab cov injectors raug txib kom xoom roj, tus neeg tsav tsheb cia siab tias yuav muaj kev sib txuam, kev kwv yees rov qab quab yuam. Ntawm Scania R500 nqis los ntawm qib 12% nrog lub cav ntoo thauj khoom, ib qho Bosch 1805344 injector dhau los ua qhov tsis pom kev saboteur: nws rab koob nozzle tau tsim 2-micron yaig channel ntawm lub rooj zaum, tso cai rau minuscule kom muaj nuj nqis ntawm diesel los nkag rau hauv txhua qhov kev sib tsoo chamber. Qhov no roj ignites, ua ib tug phantom zog mem tes uas tam sim no fights lub nres nres, destabilizing tag nrho cov downhill khiav thiab yuam tus neeg tsav tsheb mus rau qhov kev pab cuam brakes. Bosch 1805344 remanufactured common rail injector silences this phantom combustion by restoring a zero-leak needle seat validated at 1800 bar static pressure, xa rov qab lub Scania DC13 lub cav kom huv si, kwv yees lub cav nres uas ua rau lub hauv paus nres txias thiab tus neeg tsav tsheb hauv kev hais kom ua.

 

 

Bosch 1805344 yog remanufactured common rail injector, nqa lub network ntawm cross-referenced identifiers uas xauv nws rau hauv Scania DC13 (Euro 6) thiab DC09 (Euro 5/Euro 6) cav tsev neeg.

Tus lej Bosch no qhia txog nws qhov kev tsim vaj tsev sab hauv nrog chav sib pauv 0 986 441 108, lub hauv paus ntawm Scania common rail injector program. Lub 1805344 tsis yog ib qho kev hloov pauv dav dav - nws yog Scania-calibrated tivthaiv uas nws lub nozzle tsuag lub kaum sab xis, rab koob nqa profile, thiab IQA code yog sib phim rau lub cav tswj qhov kev txhaj tshuaj daim ntawv qhia rau kev pom kev combustion thiab aftertreatment thermal tswj.

 

 

Lub 1805344 yog engineered rau Scania modular DC cav platform, ib tsev neeg ntawm inline 5- thiab 6-lub tog raj kheej powerplants uas hwj chim txhua yam los ntawm ntev-haul G-series tsheb laij teb mus rau off-highway industrial units.

Tag nrho-load txhaj tshuaj kom muaj nuj nqis yog calibrated rau 85 ± 4 mm³ / stroke ntawm 1800 bar rail siab. Lub peev xwm no txhawb nqa lub zog siab kawg thaum tswj hwm qhov dav dav dav - los ntawm kev txhaj tshuaj ntawm 1.5 mm³ / stroke mus rau qhov siab tshaj plaws ntawm 180 mm³ / stroke thaum lub zog siab. Thaum lub cav nres ua haujlwm, lub injector yuav tsum xa cov roj xoom hla txhua lub tog raj kheej, ib qho xwm txheej uas xav tau kev ncaj ncees ntawm rab koob lub rooj zaum.

 

 

Lub Rooj Rooj Zaum yog Lub Rooj Sib Tham Siab
Nyob rau hauv lub 1805344, lub nozzle koob rooj zaum tiv thaiv ib tug precision-av conical nto, tsim ib tug hlau-rau-hlau foob uas withstands rail siab mus txog 2000 bar. Thaum Scania EMS hais kom xoom roj thaum lub cav nres, lub solenoid tseem tsis muaj zog, lub chamber tswj tuav lub koob kom ruaj khov ntawm nws lub rooj zaum, thiab tsis muaj roj nkag mus rau hauv lub hnab ntim. Txawm li cas los xij, yog tias rab koob lossis lub rooj zaum tau tsim micro-erosion los ntawm cavitation los yog ib qho nyuaj particle cuam tshuam, cov ntaub ntawv to. Txawm hais tias 2-micron channel yuav tso cai rau cov roj nkag mus rau hauv lub combustion chamber nyob rau hauv qhov seem rail siab uas nyob rau hauv lub sij hawm braking (feem ntau 350-500 bar). Cov roj no ignites los ntawm lub tshav kub ntawm compression, tsim ib tug me me hwj chim mem tes uas counteracts lub retarding quab yuam ntawm lub pa nres nres. Tus neeg tsav tsheb pom qhov no yog ib qho kev sib tw khiav los yog poob ntawm kev sib tsoo braking.

Bosch Remanufacturing: Ib Koob Tshiab, Zero-Leak Guarantee
Bosch 1805344 remanufacturing kiag li hloov lub nozzle los ua ke. Cov koob hnav thiab lub rooj zaum tau muab pov tseg. Ib rab koob tshiab, machined los ntawm lub tshuab nqus tsev-remelted high-speed steel thiab DLC-coated, yog lapped rau hauv lub rooj zaum tshiab. Kev sib cuag band yog tsawg dua 0.5 hli dav thiab zoo kawg nkaus ncig, ua rau nws tus kheej lub zog foob uas nruj raws li kev tsheb nqaj hlau siab nce. Ntawm EPS xeem lub rooj ntev zaum, txhua txhua 1805344 tau ua qhov kev ntsuam xyuas zoo li qub: lub tshuab txhaj tshuaj yog nias rau 1800 bar thiab cais tawm rau 180 vib nas this. Lub koob yees duab siab daws teeb meem saib xyuas lub taub hau lub taub hau. Qhov kev lees paub yog xoom tee dej - tsis muaj roj tuaj yeem tawm ntawm lub nozzle. Cov txheej txheem no tau lees paub tias lub tshuab txhaj tshuaj yuav tuav lub xeev xoom-roj thaum lub sijhawm ua haujlwm ntawm lub cav nres, tshem tawm cov phantom combustion pulses uas degrade braking kev ua tau zoo thiab hnav lub hauv paus nres.

IQA Coding rau Balanced Cav Braking
Thaum lub cav nres, tag nrho rau lub tog raj kheej yuav tsum ua rau xoom torque. Yog hais tias ib tug injector lub koob xau tso cai rau ib tug me me roj xa, lub tog raj kheej generates ib tug zoo torque mem tes thaum lwm tus nyob nruab nrab. Qhov kev tsis txaus ntseeg no ua rau muaj kev vibration vibration kis los ntawm lub driveline. Lub 1805344 yog tus kheej ntws-mapped thiab muab ib tug 7-tus lej IQA code uas kho rau txhua qhov kev tsim tawm-tolerance flow deviation. Thaum programmed rau hauv Scania EMS, cov cai no ua kom ntseeg tau tias txawm tias qhov tsawg tshaj plaws txhaj tshuaj, qhov sib npaug ntawm lub tog raj kheej-rau-lub tog raj kheej yog tswj, thiab lub cav nres tseem muaj zog, sib npaug.

Q1: Yuav ua li cas lub koob me me tuaj yeem cuam tshuam rau lub cav nres yog tias lub injector tsis xav tau txhaj tshuaj?
Thaum lub cav nres, EMS txiav tag nrho cov injector energizing signals, tab sis cov tsheb ciav hlau tseem muaj zog. Ib rab koob hnav lub rooj tso cai rau cov roj nkag mus rau hauv lub tog raj kheej raws li qhov seem seem. Cov roj ignites los ntawm compression tshav kub, tsim ib tug me me zoo torque uas tawm tsam tus nres nres lub retarding quab yuam. Tus neeg tsav tsheb xav tias qhov no yog ib qho kev sib tsoo lossis tsis muaj zog nres.

Q2: Kuv puas tuaj yeem kuaj xyuas lub tshuab nqus dej tsis tau tshem cov tshuaj?
Kev soj ntsuam borescope los ntawm lub qhov hluav taws xob lub qhov hluav taws xob tom qab qhov kub kaw tuaj yeem pom cov roj ntub ntawm lub piston yas, qhia tias lub taub dej ntws. Tsis tas li ntawd, kev ntsuas kev tsheb ciav hlau siab (kev soj ntsuam kev poob siab nrog lub cav tawm) tuaj yeem txheeb xyuas lub tog raj kheej uas poob siab sai dua li lwm tus, qhia txog txoj hauv kev los ntawm lub koob txhaj tshuaj lub rooj zaum.

Q3: Puas yuav Bosch 1805344 kho qhov kev tsis txaus siab "cag nres tsis muaj zog" ntawm kuv Scania R450?
Yog hais tias qhov kev tsis txaus siab yog tshwm sim los ntawm ib los yog ntau tshaj injectors nrog micro-tawg thaum lub sij hawm braking, hloov lub offending injector nrog ib tug 1805344 yuav restore tag nrho engine nres kev ua tau zoo. Txawm li cas los xij, xyuas kom cov pa nres valve, VGT actuator, thiab kev tswj huab cua kuj ua haujlwm kom raug, vim tias cov haujlwm no ua haujlwm.

Q4: Puas yog lub tshuab txhaj tshuaj no xav tau qhov tshwj xeeb Scania EMS software hloov tshiab tom qab kev teeb tsa?
Tsis tas yuav hloov kho software. IQA code yuav tsum tau nkag mus siv Scania SDP3 lossis cov cuab yeej kuaj mob tau zoo, thiab rov pib dua cov kev hloov pauv roj yuav tsum tau ua. EMS yuav siv cov tshuaj txhaj tshuaj tshiab cov ntaub ntawv calibration tam sim ntawd.

Q5: Puas yog Bosch 1805344 rov qab-tshaj nrog Euro 5 Scania xyaw?
Yog lawm. Lub 1805344 yog sib xws nrog Euro 5 thiab Euro 6 versions ntawm Scania DC09 thiab DC13 xyaw uas siv ib qho kev sib koom ua ke rail txhaj tshuaj. Nco ntsoov xyuas tus naj npawb injector uas twb muaj lawm ua ntej xaj.

Q6: Dab tsi tiv thaiv lub rooj zaum koob tshiab los ntawm kev tsim cov micro-erosion tib lub sijhawm?
Lub DLC txheej ntawm koob muab ib qho nyuaj, tsis tshua muaj kev sib txhuam nto uas tiv thaiv cavitation yaig thiab abrasive hnav. Siv cov roj av zoo zoo nrog lubricity txaus thiab tswj xyuas cov roj lim hloov lub sijhawm yuav ua rau lub rooj zaum muaj kev pabcuam zoo tshaj plaws.
