1, cov ntsiab lus qhia
Qauv thiab Hom: 3408324 yog ib qho hluav taws xob hluav taws xob rau cov roj twj tso kua mis (haum rau lub zog)
Siv cov qauv: Feem ntau nruab nrog Cummins engins xws li M11, NTA55, KTA19, thiab lwm yam}
Cov tub ntxhais muaj nuj nqi: los ntawm kev kho cov roj twj tso kua mis roj lub qhov, ua tiav kev kho kom haum ntawm lub cav ceev thiab hwj huam {}}
2, Ua haujlwm ua haujlwm
Electromagnetic Dratchism:
Tom qab ncaj qha tam sim no yog thov rau cov kauj, lub zog yog tsim tawm ntawm lub rotor kom tig, hloov cov roj tso tawm thiab hloov cov roj kom muaj nuj nqis .
Lub sijhawm teb tsuas yog 15 milliseconds, ua kom nrawm nrawm tswj kev teb.
• Nrhiav tau cov haujlwm ua haujlwm:
Thaum muaj hwj chim rau, nws ua rau muaj lub suab nrov (2 feem ntau tau kaw suab) {}}}}} Yog tias lub suab, nws qhia tau sab hauv daim npav jamming lossis tshuab tsis ua cas.
3, Cov Qauv Tsim Qauv thiab Kev Ntsuas Cov Qauv
1. cov qauv tseem ceeb:
Kev ua kom pom muaj kev sib txhuam siab, tab sis kev sib koom ua ke, thiab muaj kev sib koom ua ke, thiab muaj kev sib koom ua ke
Ob chav O-nplhaib foob: kom tiv thaiv kom muaj roj to, lubricating roj yuav tsum tau thov thaum lub sij hawm teeb tsa ua nruj me ntsis hauv kev sib tw.
{{02. Cov ntsiab lus tseem ceeb:
4, cov qauv ua tsis tiav thiab kev tsom xam
{{0 {}} tshuab tej yam ua yuam kev:
Daim npav muab / mus ncig ua si: vim yog impurities thiab noo noo nyob rau hauv cov roj, uas yog kev sib txig tsis muaj xeb ({} rpm)}.
Oil leakage leads to idle loss of control: After wear and tear, the clearance increases, and the fuel leakage exceeds the required amount for idle. After unloading, the idle speed remains high (>900 rpm), thiab lub nra nce ua ntej nws tuaj yeem rov qab mus rau qhov qub.
{{0 {}} Hluav Taws Xob Hluav Taws Xob:
Coil luv Circuit Court / Qhib Circuit Court: Txawv tebchaws tsis kam lees qhov kev txhaum cai ntawm lub cav "}}
Abnormal control signal: ECU drive circuit fault or poor grounding, check the harness resistance (should be>100k Ω) and signal voltage (>3V).
3.} sib piv thiab teeb meem kev teeb tsa:
Kev tsis sib haum xeeb nrog kev tswj hwm hom: ib txwm kaw actuator ua khub nrog ib txwm qhib kev tswj tswj tswj hwm tau tuaj yeem ua rau "qib siab ceev" lossis muaj peev xwm nce nrawm.
Improper tightening of bolts: Failure to tighten them step by step in the order of "bottom → left → right" (half tightening 2.8N · m → full tightening 5.6N · m) can easily cause seal failure or eccentric jamming.
5, Txhaum kev kuaj mob thiab cov qauv kuaj
1. Kev Tshawb Fawb Ua Ntej:
Mloog lub suab: Tsis muaj tseeb ob lub suab nrov thaum muaj zog ntawm → xav tias daim npav jamming .
Kev tawm tsam ntsuas: Ua kom nruj cov ntsaws thiab ntsuas cov coil kam (7 {}}}}} ωω 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4ωω 22. Yog tias nws deviates, nws yuav tsum tau hloov.
Txheeb xyuas cov roj Circuit Court: Roj lim cov thaiv lossis dej tso dej yuav ua kom nrawm actuator hnav .

3. Daim ntawv thov ntawm cov cuab yeej tshwj xeeb:
Siv OBD SCETOSTIM TEAM los nyeem cov neeg ua txhaum cai (xws li P0620), ua ib qho kev xeem yuam kev los qhib cov actuator awuator .
6, kev teeb tsa thiab txij nkawm cov lus qhia tshwj xeeb
• Cov ntsiab lus teeb tsa:
Hloov cov tshuaj o-ntiv nplhaib nrog lub tshiab thiab siv roj ci tshiab {}}}}}}}}} {{2 {.
• Ntsuas kom txuas ntxiv limespan:
Kev Pom Cov Khoom Siv Hluav Taws Xob: tsis tu ncua hloov lub lim kom ntseeg tau tias cov roj yog dawb ntawm impurities thiab noo noo .
Lwm txoj kev daws teeb meem: Rau cov xwm txheej nrog cov kev cai ceev (xws li cov tshuab roj ceev lossis cov tshuab solenoid valve siv tau los txo cov nqi thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lub neej thiab txuas ntxiv lim tiam
7, Cov ntsiab lus thiab cov lus qhia
Lub 3408324 hluav taws xob roj tswj yog cov tseem ceeb ntawm kev tswj hwm hluav taws xob, thiab ua kom muaj kev kho hluav taws xob, nws yog qhov tsim nyog ua raws li kev tswj hwm hluav taws xob, nws yog qhov tseeb} yog pom zoo kom cov kev txhim kho kom muaj kev txhim kho cov khoom siv lossis hloov mus rau hluav taws xob valve tsim kho cov kev pab cuam tshuam rau kev siv hluav taws xob {}}
