Q1: Puas yog 4P-9076 injector haum rau txhua lub cav 3508E, 3512E, thiab 3516E?
A: Yog, nws yog universally sib xws nyob rau hauv 3500E Series nrogAWM A5. Txheeb xyuas koj tus lej Serial - cov chav nyob thaum ntxov yuav xav tau ECM flash kom paub txog cov lej nkag tshiab.

Q2: Dab tsi ua rau ntxov ntxov 3500E injector tsis ua haujlwm?
A: Kev sib kis thiab dej nkag. Covkev tsheb ciav hlauua haujlwm nrog micron clearances; particle tshaj10 micronstuaj yeem tau qhab nia plungers. SivKab ntsig -cov lim dej tshwj xeebthiab tso dej cais tawm txhua hnub.

Q3: Yuav tsum muaj siab - cov kab hluav taws xob siab hloov nrog txhua qhov kev pab cuam injector?
A: Yog lawm. Cov153-5938kab yogib zaug - siv- cov txiv ntseej flare thiab lub rooj zaum deform mus tas li ntawm thawj lub zog. Reusing ib kab ua raumicro- ntxhov siabthiab siab -sab siab.

Q4: Kuv yuav xaiv li cas ntawm 10R1285 thiab 10R1290 O- cov khoom siv ntiv nplhaib?
A: 10R1285fits txheem bores;10R1290suitsloj boreslos ntawm kev kho lub taub hau. Ntsuas bore txoj kab uas hla kom tsis txhob sealing tsis ua hauj lwm thiab gas intrusion mus rau hauv lub rov qab Circuit Court.

Q5: Lub sijhawm hloov pauv rau 3500E injectors hauv thawj lub zog yog dab tsi?
A: Teem sijhawmkev ntsuam xyuas ntwsntawm4,000 teevkev kho valve. Hloov feem ntau tshwm sim ntawm8,000–10,000 teev, sib txawv nrog roj zoo thiab thauj khoom. Saib raucov pa luam yeeb dubthiab siabtso cua sovraws li hnav cov cim.

Q6: Puas yog cov khoom siv no sib haum nrog ULSD thiab biodiesel blends?
A: Yog. Pebnitrile thiab PTFEseals tiv thaiv ULSD thiabB20oxidation. Khaws ciacetane nce 45thiab xav txoglubricity additivesyog tias cov roj zoo tsis meej- lub siab - lub twj tso kua mis tso siab rau roj rau hauv lubrication.
