04286450 Diesel Common Rail Pump - Dynamic Flow Regulator Nrog Adaptive Pressure Control

Thaum rail siab sib txawv tshaj 30 bar thaum lub sij hawm tip-in acceleration, combustion efficiency poob los ntawm ze li ntawm 2.5%, txhais mus rau hauv pom cov pa luam yeeb dub thiab 4-6% nplua nyob rau hauv roj kev lag luam. Cov04286450hais qhov no tsis yog los ntawm kev nce siab siab, tab sis los ntawmshortening lub siab-tsim ncualos ntawm idle mus rau tag nrho load mus rau hauv 180 milliseconds. Qhov no yog ua tiav los ntawm afeedforward-plus-PID tswj logicembedded nyob rau hauv lub twj tso kua mis integrated digital valve tsav tsheb - ib tug feature tsis tshua muaj pom nyob rau hauv tom qab kev hloov pauv ntawm tus nqi tier.

Ntau dua li kev sib tw ntawm qhov siab tshaj plaws kev ntaus nqi, 04286450 tsom rausiab-nce linearityhla tag nrho lub cav ua haujlwm daim ntawv qhia. Nws internal cam phaj siv asib txawv-radius profileuas nce zuj zus plunger tshaj tawm raws li kev ceev nce, kom ntseeg tau tias roj ntim ib qho kev mob stroke tseem zoo ib yam txawm tias thaum lub cav rpm hloov pauv los ntawm ± 200 rpm vim lub iav hloov lossis PTO kev koom tes. Rau cov neeg tsav nkoj, qhov no txhais tau tias cov lus teb zoo dua thiab rov tsim dua tshiab rau DPF - qhov kev ua haujlwm ncaj qha tus nqi txuag.

1. Ultra-Fast Metering Valve teb

Lub twj tso kua mis solenoid-tsav metering valve ua tiav apuv-stroke qhib lub sij hawm ntawm 2.1 msthiab kaw tsis pub dhau 1.8 ms, ua rau lub voj voog-los ntawm-lub voj voog roj trimming. Qhov kev teb no yog qhov tseem ceeb rau cov cav nruab nrogntau yam kev txhaj tshuaj(pilot, main, post) qhov twg lub sij hawm qhov rais shrink rau 0.5℃crankshaft kaum sab xis ntawm high speeds. Lub valve lub armature yog coated nrog anon-magnetic hnav txheej, tshem tawm cov teeb meem uas feem ntau tau tshaj tawm nrog cov qauv steel-on-steel tsim tom qab 300,000 km.

2. Active Thermal Compensation System

Diesel roj viscosity sib txawv los ntawm ntau tshaj 300% ntawm qhov txias pib ntawm -20℃thiab tag nrho ua haujlwm sov ntawm 80 degree. Lub 04286450 suav nrog abimetallic tswj lub tes tshouas kho qhov nqus throttle qhib raws li roj kub - tsis yog los ntawm lwm lub sensor, tab sis ntawmtxawv thermal expansionntawm ob lub nplhaib concentric. Qhov kev ua haujlwm tsis zoo no tswj xyuas qhov ntim ntim hauv ± 2% thoob plaws tag nrho qhov ntsuas kub, txo qhov kev xav tau ntawm ECU kho cov duab kos thiab ua kom yooj yim tom qab kev lag luam calibration.

3. Plunger & Barrel Durability Upgrade

Cov twj tso kua mis yog tsim nrog asilicon-nitride infused DLC (pob zeb diamond-zoo li carbon) top-txheej, dhau ntawm hardened chromium-nitride puag. Laboratory hnav kuaj (ISO 12156-1 HFRR) qhia a73% txo qhov caws pliav kabpiv rau uncoated plungers thaum khiav ntawm qis-sulphur diesel nrog 5% FAME. Rau cov neeg siv khoom siv biodiesel sib tov txog B30, qhov no txhais tau tias kwv yees900,000-km kev pab cuam lub sijhawmua ntej ntsuas cov dej ntws sab hauv tshaj 15 ml / min - ib daim duab tau lees paub los ntawm cov ntaub ntawv teb los ntawm European kev koom tes ua liaj ua teb.

04286450 yog tsim los ua ib tughloov kev pabcuam ncaj qharau cov cav uas thaum xub thawj siv Bosch CP1 / CP3-derived twj nrog kev hloov pauv zoo sib xws. Verified Fitments muaj xws li:

Cummins ISB 6.7 TSI(2010-2019, tom qab ua lag luam calibration yuav tsum tau rau qee qhov sib txawv)

Weichai WP10 / WP12(Euro III rau V series nrog phau ntawv hloov sijhawm)

Deutz TCD 6.1 / 7.8(Agriculture thiab kev tsim kho khoom siv)

Perkins 1200-series(Lub tshuab hluav taws xob teeb tsa txog 250 kVA)

Installation Note:Lub twj tso kua mis ships nrog arotatable inlet luj tshib- loosen lub nplhaib clamp thiab taw qhia cov khoom siv roj kom tsis txhob cuam tshuam nrog cov kav dej turbocharger. Lub sij hawm yog teem los ntawm lubpeb-qhov coupling; ua kom lub cim "0" ntawm lub iav tsav nrog lub cav TDC qhov taw qhia, tom qab ntawd tig lub twj tso kua mis lub cev kom txog rau thaum tus xa khoom valve tuav nrog cov ntaub ntawv siv (cov lus qhia ntxaws qhia los ntawm QR-txuas video).

Rau cov ntawv thov rov qab siv dua, lub ntsuas ntsuas lub valve lub PWM zaus yog lub Hoobkas teeb tsa rau 120 Hz, sib piv ECUs feem ntau (Bosch EDC16/17, Denso SH2, Delphi F2). Yog tias koj tus maub los siv ntau zaus (piv txwv li, 80 Hz lossis 200 Hz), lub valve tuaj yeem rov ntsuas dua siv tus tsav tsheb sab nraud - hu rau kev txhawb nqa rau cov txheej txheem rov ua haujlwm.

Tom qab 180 hnub ntawm kev saib xyuas thoob plaws 12 lub nkoj (sib xyaw ntawm-txoj kev thiab tawm-txoj kev), tus 04286450 qhia tsis tu ncua:

Kev txo lub sij hawm pib txias- nruab nrab 1.2 vib nas this sai dua kom ruaj khov ntawm -15℃piv rau OEM twj.

Rail siab ripple- Tsawg dua los yog sib npaug rau ± 12 bar ntawm kev caij nkoj tsis tu ncua, piv rau ± 25 bar rau lwm txoj hauv kev.

Sab nraud leak rate– xoom tsis ua hauj lwm ntawm ncej di ncauj ntsaws ruaj ruaj thaum lub sij hawm xeem lub sij hawm (lub ob-lip di ncauj PTFE foob tsim tau txais credit).

Suab nrov pab- A-weighted suab zog theem ntawm 78 dB (A) ntawm 1 m, ua rau nws yog ib qho ntawm cov twj ntsiag to hauv nws chav kawm hloov chaw.

Txheej txheem Priming:Ib txwm siv lub tshuab nqus tsev nqus kom rub cov roj los ntawm lub twj tso kua mis ua ntej pib - cranking yam tsis muaj prime tuaj yeem ua rau cov plungers hauv vib nas this.

Lim hloov lub sijhawm:Hloov lub inlet pre-screen txhua 50,000 km lossis 500 teev; tsis txhob cia siab rau lub ntsiab roj lim.

Torque qhov tseem ceeb:Mounting bolts - 25 Nm + 60℃kaum sab xis; xa kab txiv ntseej - 30 Nm (thov ib qho kev tiv thaiv kev ntes rau cov xov).

ECU adaptation:Tom qab kev teeb tsa, ua "fuel quantity adaptation reset" siv cov software kuaj mob - qhov no tshem tawm cov txiaj ntsig tau los ntawm lub twj tso kua mis dhau los thiab tiv thaiv kev siv roj ntau dhau ib ntus.

Q1: Puas tuaj yeem 04286450 hloov lub twj tso kua mis CP1 ntawm 2007 Cummins ISB yam tsis tau hloov cov kab roj?
Yog lawm, qhov chaw nres nkoj qhov hluav taws xob thiab qhov ntau thiab tsawg ntawm xov (M14 × 1.5 rau cov kab hluav taws xob siab) phim CP1 tus qauv. Txawm li cas los xij, CP1 siv qhov sib txawv tsav sib txuas - koj yuav tsum tau xaj qhov kev xaiv 12-hlau tsav hub (muag nyias) rau kev sib raug zoo nrog koj lub cav tsheb ciav hlau. Lub tshuab hluav taws xob txuas rau lub ntsuas ntsuas valve kuj tau sib xws nrog tus qauv 2-pin Deutsch ntsaws.

Q2: Kuv ua haujlwm hauv qhov chaw muaj plua plav heev (tsuas yog mining). Lub twj tso kua mis no puas muaj kev tiv thaiv ntxiv rau lub tshuab tsav lub tog raj kheej?
Yog lawm. Lub foob foob txuas nrog rau sab nraudxav wiperuas tshem tawm cov plua plav thiab av nkos ua ntej lawv ncav cuag lub qhov ncauj qhov ncauj. Lub wiper no yog hloov tau yam tsis tau disassembled lub twj tso kua mis - tsuas yog tshem tawm lub nplhaib snap thiab rub nws tawm nrog pliers. Peb pom zoo kom tshuaj xyuas lub wiper txhua 1,000 teev ua haujlwm hauv cov xwm txheej hnyav.

Q3: Lub twj tso kua mis qee zaus ua rau lub suab nrov nrov ntawm 2,000 rpm. Puas yog qhov tsis xws luag?
Tsis yog - qhov no yog qhov qub resonance ntawm lub siab nyem valve lub pilot theem thaum ua hauj lwm nyob ze ntawm lub bypass pib (nyob ib ncig ntawm 1,650 bar). Nws qhia tau hais tias lub valve tau teb kom raug rau kev hloov pauv dhau-siab. Yog hais tias lub xuav ua tsis tu ncua los yog nrog los ntawm kev poob hauv kev tsheb ciav hlau siab, xyuas cov kab rov qab rau kinks uas tuaj yeem ua rau siab rov qab siab dua 1.5 bar.

Q4: Dab tsi yog qhov txawv ntawm 04286450 thiab cov laus 0445010-series twj?
04286450 muaj aloj-inch plunger(12 mm vs . 10 mm) thiab asiab dua-flow metering valve, tso cai rau nws los txhawb cov cav txog li 400 HP, qhov 0445010 txwv rau ~ 300 HP. Tsis tas li ntawd, tus qauv tshiab siv akaw ECU interfaceuas tiv thaiv kom tsis txhob ya raws - ib qho kev ua tsis tiav ntawm qhov qub qhib-connector tsim.

Q5: Kuv puas tuaj yeem khiav lub twj tso kua mis no nrog 100% HVO (hydrotreated zaub roj) lossis paraffinic diesel?
kiag li. HVO muaj lubricity zoo dua thiab qis dua, uas ua rau txo lub twj tso kua mis sab hauv kev sib txhuam. Lub DLC txheej ua tau zoo dua nrog HVO vim nws cov khoom siv ntau dua, ua rau muaj kev sib zog me ntsis sai dua. Tsis tas yuav hloov lub twj tso kua mis lossis ECU - tsuas yog xyuas kom cov roj viscosity nyob qis dua 2.5 cSt ntawm kev ua haujlwm kub.

Q6: Kuv yuav ua li cas thiaj paub tseeb tias kuv lub twj tso kua mis yog qhov tseeb - puas muaj cov cim cuav?
Txhua yam 04286450 muaj alaser-etched alphanumeric codentawm lub mounting flange, nyeem tau hauv qab 10 × magnifier. Cov cai sib phim tus lej batch luam tawm ntawm lub thawv sab hauv. Tsis tas li ntawd, cov twj tso kua mis tiag muaj ib qhontsuab-xim O-ringnyob rau ntawm lub metering valve connector - cov khoom cuav feem ntau siv cov roj hmab dub lossis txiv kab ntxwv. Sau npe koj tus lej xov tooj hauv online kom qhib tau 2-xyoo lav.
