HX35W Turbocharger – Pulse-Tuned Rau Cummins 6BT|Surge-Npaj Txhim Kho Kom Zoo Rau Siab-Siab Common-Rail Conversions

Lub HX35W (Tshooj No. 3802778 / OEM 3592766) tsis yog lwm qhov poob - hloov; nws yog ib tug khiav-calibrated ntsuas uas reinterpres li cas pa pulse zog yog sau los ntawm 6BT's inline- rau firing xaj. Qhov twg feem ntau tom qab kev lag luam turbos tseem ceeb tshaj plaws lub zog siab tshaj plaws, chav tsev no tsom raumem tes sib cais- siv lub vaj tse asymmetrical faib turbine (ntxaib- nkag, 120℃sib cais) uas txo tus ntoo khaub lig- lub tog raj kheej cuam tshuam thaum lub sijhawm sib tshooj. Rau cov tswv retrofitting mechanical 6BT engines nrog hluav taws xob ntau -rail txhaj tshuaj (piv txwv li, P- twj tso kua mis rau CP3 hloov dua siab tshiab), qhov tsim no suppresses lub cyclic variation nyob rau hauv rail siab uas feem ntau tshwm sim ntawm 2,200-2,600 rpm, txiav siab ripple los ntawm ± 120 bar mus rau ± 35 bar rau precision txhaj tshuaj.

Turbine Housing Configuration:Sib faib nkag nrog qhov tseeb A / R ntawm 0.91 (kub sab), ua kom zoo rau cov pa tawm pa tawm raws li 6BT's 120℃crank intervals.

Compressor Log Inducer:56.0 mm / exducer 76.2 mm – daim ntawv qhia dav npog 0.18–0.52 kg/s, nrog ib tug surge kab hloov 15% sab laug piv rau generic HX35 variants.

Wastegate Actuator:Integrated boost- tswj tau, preloaded mus rau 22 psi, nrog ib tug stroke nkhaus uas phim 6BT lub Tshuag boost luj tshib; adjustable ntawm 6-mm hex txiv ntseej rau fine-tuning.

Bearing System:Siab- pub cov bushings floating nrog rau cov roj inlet loj (M12 × 1.5) thiab ua tau - nyob rau hauv txwv (0.9 mm) kom tsis txhob over- roj thaum pib txias - paub qhov mob ntawm qhov siab - mais Cummins blocks.

Turbine Log Khoom:Inconel 718 nrog 10-hnav tsis muaj kev tsim qauv, ntsuas rau 760℃nruam thiab 830℃ncov (20-thib ob overshoot tso cai).

Cummins 6BT 5.9L (tswj twj tso kua mis thiab thaum ntxov VP44-tsim qauv, 1994-2002 Dodge Ram).

Muaj ntau hom: Case IH tsheb laij teb, New Holland ua ke, thiab Onan gensets siv 6BT puag.

Bolt- ntawm kev sib raug zoo nrog tus qauv T3 flange manifolds; yuav tsum tsis muaj adapter phaj.

Lub 6BT yog Ameslikas lub tshuab tshuab, tab sis muaj kev vam meej tom qab kev lag luam muaj nyob rau ntau - kev hloov tsheb ciav hlau siv Bosch CP3 lossis Denso HP5 twj. Hauv cov kev teeb tsa no, ECU tso siab rau qhov sib luag, cov kab hluav taws xob txhawb nqa los suav cov roj ntau. HX35W's compressor map nta aflatter efficiency kob(72–78%) thoob plaws 2.0–2.8 siab piv band, uas ncaj qha txhais mus rau tsawg dua "boost spikes" uas tsis meej pem txoj kev tsheb ciav hlau - siab PID maub los. Kev nkag teb chaws los ntawm kev sim mule (1998 Dodge 2500, CP3-swapped) tau pom tias HX35W txo cov kev txhaj tshuaj kho los ntawm 22% thaum lub sij hawm 6% qib rub ntawm 65 mph, piv rau HX35 tus qauv. Qhov tshwm sim: txias EGTs (los ntawm ~ 50 degree) thiab ruaj khov zoo dua thaum lub A / C compressor cycles.

Roj ntws flange: Siv lub Hoobkas 1/2 "NPT adapter, tab sis txheeb xyuas qhov dej ntws txoj kab nqes - tsawg kawg 5℃downward los tiv thaiv crankcase siab rov qab.

Cov pa roj carbon monoxide: Muab nrog ntau- txheej steel (MLS) gasket; torque manifold studs mus rau 45 ft -lbs nyob rau hauv ib tug kauv qauv.

Boost reference chaw nres nkoj: Lub tsev nyob compressor suav nrog kev mob siab rau 1/8 "NPT chaw nres nkoj rau sab nraud boost gauges lossis hluav taws xob sensors - tsis txhob tee rau hauv kab khib nyiab, vim nws hloov cov lus teb ntawm actuator.

Pom zoo so-nyob rau hauv: Idle rau 3 feeb, tom qab ntawd siv 50% load rau 10 feeb ua ntej puv -throttle operation - lub caij no lub bushing nto.

Q1: Kuv tab tom khiav ib qho - kev hloov tsheb ciav hlau nrog lub twj tso kua mis hloov kho - lub turbo no puas tuaj yeem ua haujlwm siab dua (piv txwv li, 1,600 bar)?
Yog, lub turbine vaj tse thiab lub log tsis cuam tshuam los ntawm kev tsheb ciav hlau siab. Txawm li cas los xij, kev tsheb ciav hlau siab dua feem ntau txhais tau tias muaj roj ntau dua, uas nce EGTs. Saib xyuas koj lub pyrometer - yog tias EGT siab tshaj 700℃rau ntau tshaj 10 vib nas this, xav txog lub vaj tsev loj dua (peb muab kev xaiv 0.96 A / R) lossis dej - tshuaj methanol.

Q2: Muaj me ntsis "flutter" suab nrov ntawm lub compressor thaum kuv tso tawm lub throttle - puas yog qhov puas tsuaj?
Qhov no yog compressor surge thaum lub kaw lus kaw. HX35W's surge margin yog dav dua li feem ntau, tab sis yog tias lub suab nrov nrov, xyuas koj qhov kev txwv huab cua. Lub lim lim lim hloov qhov chaw ua haujlwm mus rau qhov nce siab. Hloov cov khoom yog tias lub siab poob siab tshaj 5 inH₂O.

Q3: Kuv puas tuaj yeem siv cov khoom khib nyiab tuaj yeem nrog lub tshuab hluav taws xob txhawb nqa?
Yog - tus actuator lub caij nplooj ntoos hlav tus nqi yog linear. Rau cov tswj hluav taws xob, tsuas yog cap lub siab siv hose thiab txuas koj lub solenoid rau tib qhov chaw nres nkoj. Teem koj tus maub los rau hauv lub voj voog lub luag haujlwm ntawm 25% thiab nplua -tune los ntawm qhov ntawd; lub tuaj yeem teb tau zoo rau PWM cov teeb liab mus txog 30 Hz.

Q4: Kuv 6BT muaj 300,000 mais - Kuv puas yuav tsum hloov cov roj noj kab thaum txhim kho lub turbo?
kiag li. Cov kab qub qub feem ntau muaj kev txwv orifices thiab roj hmab liners uas delaminate. Siv cov kab tshiab braided stainless hlau nrog 0.9-mm txwv kev sib xyaw ua ke - peb pom zoo kom peb cov khoom siv (ib feem naj npawb HX35-OIL-01) kom ntseeg tau tias cov roj ntws zoo yam tsis muaj overpressurizing cov ntawv xov xwm bearings.

Q5: Lub turbo no siv rau hauv Dodge Rams thiab cov khoom siv ua lag luam - puas qhov chaw khib nyiab txawv?
Rau kev siv tsheb, 22 psi yog qhov zoo tagnrho rau kev thauj khoom. Rau cov gensets nyob ruaj ruaj (s tas li 1,800 rpm), thim rov qab lub preload mus rau 18 psi kom tsis txhob muaj kev txhawb nqa tsis tsim nyog thaum tsis muaj - thauj khoom - qhov no tuaj yeem txuas lub neej ntev txog 2,000 teev.

Q6: Kuv yuav ua li cas paub qhov txawv HX35W units los ntawm cov ntawv luam uas zoo ib yam?
Txheeb xyuas cov turbine inlet casting - cov chav muaj tiag muaj "HX35W" engraving nrog ib tug batch code pib nrog "38" nyob ze ntawm lub pov tseg pivot. Tsis tas li ntawd, hnyav lub compressor log; thawj siv forged 2618 aluminium alloy (kwv yees . 185 gram), thaum cov khoom cuav yog hnyav dua cam khwb cia zinc-alloy (tshaj 220 grams) thiab ua rau cov hniav tsis ua haujlwm.
