Bosch 1730888 - HPI Choj hauv Scania's Fuel Injection Evolution

Nyob rau hauv ncua sij hawm ntawm kev txhaj tshuaj roj diesel, muaj cov neeg kho tshuab dinosaurs, muaj tag nrho cov digital -rail marvels - thiab tom qab ntawd muaj tus choj ntawm lawv. Bosch 1730888 tuav tus choj ntawd. Nws yog Scania OE tus lej rau ib qhoElectronic Unit Injector (EUI)uas powered qhov kev hloov los ntawm cov khoom siv hluav taws xob nkaus xwb xa mus rau kev tswj hwm hluav taws xob uas txhais tau tias niaj hnub diesel.

Thaum Scania's XPI system tom qab tau coj ntau- kev tsheb ciav hlau thev naus laus zis mus rau pem hauv ntej, HPI (High Pressure Injection) architecture sawv cev los ntawm 1730888 xa hluav taws xob lub sijhawm tswj tsis tau tso tseg lub hauv paus kev siv tshuab zoo ntawm cam- tsav tsheb. Rau cov neeg tsav nkoj uas khiav Euro 3 thiab Euro 5 Scania tsheb, qhov kev txhaj tshuaj no tsis yog ib feem qub txeeg qub teg - nws yog tus yuam sij kom khaws ntau lab -kilometer workhorses ntawm txoj kev.

 

 

 

Lub 1730888 belongs rau lubHPI (High Pressure Injection)tsev neeg - Scania's pre-XPI hluav taws xob txhaj tshuaj. Tsis zoo li ntau- txoj kev tsheb ciav hlau uas cais lub zog tsim los ntawm kev txhaj tshuaj, HPI unit injector integrates ob txoj haujlwm:

Camshaft-tsav plunger- pressurizes roj hauv lub cev injector

Electronic solenoid- tau txais PWM cov cim los ntawm ECU los tswj lub sijhawm thiab sijhawm

Integrated nozzle- atomizes roj ncaj qha mus rau hauv combustion chamber

Qhov no hybrid tsim muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb no: lub durability thiab simplicity ntawm ib tug neeg kho tshuab injector, nrog rau cov precision ntawm hluav taws xob tswj. Lub 1730888 yog qhov ua kom zoo ntawm qhov kev xav no - ib feem uas tsis yog xa roj xwb, tab sisorchestratescombustion txheej xwm nrog ECU- qhia qhov tseeb.

 

 

 

1730888 yog Scania's OE tsim rau Bosch chav injector uas muaj ntau tus neeg:

Tus cim	Tus nqi
Scania OE Naj Npawb	1730888
Alternative Scania Number	1730800
Bosch New Number	0 414 701 061

Tsheb Series Coverage

Lub injector tshwm nyob rau hauv:

Scania P-series- kev faib khoom thiab thauj hauv cheeb tsam

Scania G-series- hnyav- lub luag haujlwm thiab kev tsim kho

Scania R-series- ntev - tsheb thauj khoom

Scania F-series- cab- hla - tsheb cav

Ntau xyoo siv sijhawm kwv yees2004 txog 2018, suav nrog Euro 3 txog Euro 5 emission qauv. Lub qhov rais txuas ntxiv no piav qhia tias vim li cas 1730888 tseem yog qhov siab -xav tau qhov hloov pauv - ntau lab ntawm Scania tsheb thauj khoom thaum lub sijhawm no tseem ua haujlwm thoob ntiaj teb.

Cov ntawv thov kev lag luam

Tshaj li ntawm - tsheb loj, 1730888 kuj tseem ua haujlwm rau kev lag luam fais fab thiab tawm - cov cuab yeej loj siv los ntawm Scania DC-series cav. Nyob rau hauv cov luag hauj lwm no, qhov twg downtime yog ntsuas nyob rau hauv poob ntau lawm, injector kev ntseeg tau txhais ncaj qha mus rau lub lag luam profitability.

 

 

Precision Roj Metering

Lub 1730888 xamuaj tseeb roj metering thiab optimized atomization, kom ntseeg tau tias muaj kev sib tsoo zoo, kev ua haujlwm ruaj khov ntawm lub cav, thiab txhim kho roj kev lag luam hauv kev siv hnyav -. Lub solenoid- tswj kev txhaj tshuaj tso cai rau ECU los kho cov roj xa hauv lub sijhawm raws li kev thauj khoom, nrawm, kub, thiab qhov siab - ib yam dab tsi uas cov tshuab txhaj tshuaj tsis tuaj yeem ua tiav.

Durability Engineering

Tsim los ntawm Bosch's OEM qauv, 1730888 ntaCov khoom siv ruaj khov hauv cov khoom siv thiab cov tshuab sealing siab heevtsim los kom txo cov dej ntws thiab hnav. Nws txoj kev tsim kho ruaj khov ua kom muaj kev ua haujlwm zoo ib yam thoob plaws cov kev pabcuam txuas ntxiv raws li kev lag luam siv roj av.

HPI Advantage

Piv nrog rau cov neeg kho tshuab injectors, HPI system muaj:

Electronic lub sij hawm precision- cov xwm txheej txhaj tshuaj tswj tau mus rau microsecond

Txhim kho roj atomization- Cov qauv tshuaj tsuag zoo dua rau kev ua kom tiav

Txhim kho emissions tswj- Cov khoom siv hluav taws kub hnyiab tau ntsib Euro 3–5 tus qauv

Piv nrog rau XPI hom -rail systems, HPI muaj:

Pov thawj durability- tsawg dua hluav taws xob sensors thiab actuators ua tsis tau

Kev kuaj mob yooj yim- kev daws teeb meem tsawg dua

 

 

Common Failure Indicators

Cov cim ceeb toom ntxov ntawm kev ua tsis tiav 1730888 suav nrog:

Kev siv roj ntau ntxiv- feem ntau yog thawj qhov taw qhia ntawm nozzle hnav lossis tsis raug injector nqis

Cav misfire- nquag txuas rau kev ua haujlwm tsis zoo ntawm solenoid los yog teeb meem kev teeb tsa

Rough idle- lub tog raj kheej tsis txaus los ntawm kev xa roj tsis sib xws

Diagnostic txhaum cai- rov qab tau siv Scania cov cuab yeej kuaj mob

Kev Coding tseem ceeb

Ib qho kev sib txawv tseem ceeb ntawm 1730888 thiab cov neeg kho tshuab laus dua:electronic unit injectors yuav tsum tau coding. Txhua tus injector muaj cov yam ntxwv ntws tshwj xeeb, thiab ECU yuav tsum tau ntsuas kom haum. Tom qab hloov, lub rooj cob qhia yuav tsum:

Nruab lub injector tshiab nrog torque specifications

Siv cov tshuaj ntsuam xyuas software los sau npe tus injector's calibration code

Khiav ib lub tog raj kheej ntsuas kev hloov pauv kom cia ECU kawm cov tshuaj txhaj tshuaj tshiab cov lus teb

Kev ua tsis tau raws li qhov hloov pauv hloov pauv ua rau cov roj tsis tu ncua tsis tu ncua, ua haujlwm tsis zoo, thiab muaj peev xwm nce emissions.

Kev txiav txim siab tshem tawm

Scania unit injectors tuaj yeem txeeb tau hauv lub tog raj kheej lub taub hau lub sijhawm. Rhiav cov cuab yeej xws li swb rauj pullers feem ntau xav tau rau kev rho tawm. Kev ua siab ntev thiab cov txheej txheem tsim nyog yog qhov tseem ceeb - kev quab yuam ntau dhau ua rau muaj kev puas tsuaj rau lub taub hau thiab lub tog raj kheej.

Q1: Kuv Scania muaj lub cav DC9. Kuv yuav ua li cas thiaj paub tseeb tias 1730888 yog tus txhaj tshuaj zoo?

Tshawb xyuas koj lub cav uas twb muaj lawm rau Scania tus lej 1730888 lossis 1730800, lossis Bosch tus lej 0 414 701 061 lossis 0 414 701 036. Xyuas kom tseeb tias koj lub cav yog los ntawm DC9 tsev neeg (5-lub tog raj kheej, 8.9–9.0L). Yog tias koj lub Scania muaj DC11, DC13, lossis DC16 lub cav, qhov kev txhaj tshuaj no tsis sib xws - cov platforms siv cov tshuab txhaj tshuaj sib txawv.

Q2: Kuv hloov lub injector tab sis tseem muaj qhov tsis zoo. Dab tsi ua yuam kev?

Feem ntau yuavlub injector tsis tau codedmus rau ECU. Cov tshuab hluav taws xob hauv tsev muaj cov yam ntxwv ntws tshwj xeeb, thiab ECU yuav tsum tau kawm cov kev ntsuas qhov ntsuas tshiab. Yog tsis muaj coding, ECU siv cov qub injector cov roj trim qhov tseem ceeb, ua rau tsis sib xws. Siv Scania diagnostic software los sau npe tus lej injector thiab khiav lub tog raj kheej ntsuas kev hloov pauv.

Q3: Kuv puas tuaj yeem hloov tau ib qho 1730888 injector, lossis kuv yuav tsum hloov tag nrho cov tshuaj txhaj tshuaj?

Kev hloov tus kheej yog ua tauyog tias cov tshuaj txhaj tshuaj ntxiv nyob rau hauv qhov txwv tsis pub hnav. Txawm li cas los xij, rau siab - lub tsheb kauj vab (ntau tshaj 500,000 km), tag nrho - teeb hloov tau pom zoo. Kev sib xyaw cov tshuaj txhaj tshuaj tshiab nrog cov khoom hnav hnyav ua rau lub tog raj kheej - rau - lub tog raj kheej tsis sib xws uas ECU tsuas tuaj yeem them nyiaj ib nrab rau - thiab hauv 5-lub tog raj kheej DC9, qhov tsis sib xws yog qhov tshwj xeeb pom.

Q4: Yuav ua li cas txhaj tshuaj rov qab ntws pab kuaj xyuas qhov ua tsis tiav 1730888?

Kev noj qab haus huv 1730888 rov qab kwv yees li 30–50 ml / min ntawm cov pa tawm - tawm roj ntawm qhov tsis ua haujlwm. Kev xa rov qab ntau dhau (ntau dua 80 ml / min) qhia tias hnav sab hauv hauv qhov tswj valve lossis plunger - lub tshuab nqus tsev yog hla cov roj es tsis txhob xa nws mus rau lub tog raj kheej. Kev ntsuas rov qab ntws nrog lub tog raj kheej kawm tiav yog ib qho kev kuaj xyuas kev noj qab haus huv zoo tshaj plaws rau chav txhaj tshuaj. Yog hais tias ib tug injector rov qab ntws yog ho siab dua lwm tus, kev hloov yog tib txoj kev.
