Khoom taw qhia
Cummins 4376246 pistons, yog ib qho tseem ceeb tshaj plaws ntawm Cummins cav, muaj npe nrov thoob ntiaj teb rau lawv qhov tshwj xeeb, nrog rau 5.9-liter thiab 6.7-liter qauv tau txais kev nyiam tshwj xeeb. Txawm hais tias nws yog 5.9-liter Cummins pistons thaum ntxov los yog lub zog ntau dua 6.7-liter Cummins pistons, lawv cov piston tsim ncaj qha cuam tshuam rau lub cav efficiency thiab kev ntseeg tau. Qhov tshwj xeeb tseem ceeb yog cov qauv 24-valve, feem ntau hu ua 24V Cummins pistons lossis 24-valve Cummins pistons, uas ua rau muaj txiaj ntsig zoo ntawm cov roj siv hluav taws xob thiab cov khoom siv hluav taws xob los ntawm kev tsim cov combustion chamber tsim thiab cov khoom siv. Cov khoom siv piston ua haujlwm siab no yog qhov tseem ceeb ntawm kev ua haujlwm ruaj khov ntawm Cummins lub cav nyob rau hauv cov xwm txheej hnyav thiab tseem yog qhov tseem ceeb rau kev hloov kho lub cav thiab kev ua haujlwm.

| Sealing tsim | Cov qauv ntawm lub deflector zawj optimizes kev faib cov roj cav, thiab qhib clearance yog precisely tswj (sab clearance 0.25-0.5mm, kawg clearance 0.04-0.1mm). |
| Kev ua haujlwm parameter | Lub voj voog loj tshaj plaws yog 1.6 lab mais. Nws yog sib xws nrog siab - siab ntau rail systems (nrog lub siab tsis kam ntawm 1800bar) thiab ua tau raws li National VI B / Euro VI D emission qauv |
| Hnav tsis kam | Kev kho mob sib xyaw ua ke ntawm plasma molybdenum diffusion thiab tungsten disulfide (WS2) txo cov coefficient ntawm kev sib txhuam los ntawm 30% thiab ua kom lub sijhawm ua haujlwm luv luv ntawm 60%. |
| Precision manufacturing | Cov txheej txheem laser honing tswj tus ntoo khaub lig mesh qauv, kev txhim kho kev sib khi los ntawm 30% thiab ua rau nws haum rau kev ua haujlwm hnyav. |
Khoom zoo
Kev sib xyaw graphite txheej thev naus laus zis ntawm daim tiab txhim kho kev sib txhuam txo los ntawm 40%, thiab kev kho nitriding ntawm lub nplhaib grooves ua tiav qhov hardness ntawm HV800+, txuas ntxiv lub neej kev pabcuam tag nrho. Lub thickness yog nce los ntawm 15%, cia nws tiv taus 1800 bar ntawm tawg siab. Cov roj cua txias sab hauv tsim kom txo tau qhov kub thiab txias los ntawm 80-120 degree, tsis txhob muaj kev pheej hmoo ntawm melting sab saum toj. Lub piston crown kab noj hniav yog txuam nrog lub kaum sab xis injector, optimizing roj atomization efficiency thiab txhim kho lub zog tso zis stability.
FAQ
Q: 1. Dab tsi yog cov ntaub ntawv tseem ceeb thiab kev siv thev naus laus zis ntawm Cummins 4376246 piston?
A: Cov graphite txheej rau ntawm daim tiab txo kev sib txhuam los ntawm 40%, thiab lub nplhaib grooves yog nitrided rau hardness ntawm HV800+. chrome-plated compression rings (hardness HV900) txo hnav los ntawm 50%, cov roj nplhaib lub caij nplooj ntoos hlav nro yog 18-22N, thiab roj noj yog<0.1g/kWh.
Q: 2. Lub cav qauv twg yog qhov piston sib haum nrog?
A: Tsim tshwj xeeb rau 24-valve 5.9L / 6.7L cav, haum rau lub tog raj kheej bores Φ90mm-Φ160mm, ua tau raws li Tuam Tshoj VI B / Euro VI D emission qauv.
Q: 3. Yuav tiv thaiv lub tog raj kheej li cas?
A: Ua kom sov li 3 feeb tom qab pib txias kom ntseeg tau tias cov roj ua kom siab; xyuas lub nplhaib sib dhos hnav txhua 5000 teev.
Q: 4. Dab tsi yog qhov kev ntim khoom thoob ntiaj teb rau lub 4376246 piston?
A: Leak- cov ntaub ntawv pov thawj kaw, lub thawv sab nrauv sau "Qhov Tseeb" nrog cov ntawv suav thiab lus Askiv, cov khoom muaj tseeb ntim nrog nitrogen rau kev tiv thaiv noo noo, thiab nrog rau MSDS daim ntawv.
Q: 5. Yuav tsum muaj ntawv pov thawj dab tsi rau kev xa tawm mus rau Tebchaws Europe thiab Tebchaws Meskas?
A: Daim ntawv pov thawj CE (EU) lossis EPA raws li daim ntawv pov thawj (US), cov ntaub ntawv yuav tsum phim lub npe khoom tiag tiag thiab ntau.
Q: 6. Cov ntaub ntawv pov thawj kev lis kev cai yog dab tsi?
A: Daim ntawv xa nyiaj ua lag luam, cov ntawv ntim khoom, daim ntawv pov thawj ntawm keeb kwm, Cummins tiv thaiv - daim ntawv pov thawj (scratch- tawm txheej rau kev pov thawj).
