Fenomèn fay: Motè dyezèl la kòmanse nòmalman epi li travay nòmalman nan vitès san fè anyen konsa wo ak ba. Lè ekipman an anba chay lou, vitès la desann seryezman, vitès la desann nan apeprè 1100 ~ 1300rpm, ak vitès veyikil la tou ba, men li retounen nan nòmal apre li fin travay pou yon kout peryòd de tan.
Pwosesis depanaj: Tcheke presyon sistèm gaz la ak koule, epi jwenn ke presyon an ak koule yo tou de ba. Tcheke tiyo sistèm gaz yo ak filtè, epi jwenn ke gen matyè etranje kole nan ponp lwil oliv men an. Apre netwaye li, li retounen nan nòmal.
Analysis of the reasons: The diesel engine starts normally, and the high and low idle speeds work normally, indicating that there is no fault in the electrical part of the diesel engine, and the fault point should be in the fuel system. The blockage of fuel system pipelines and filters affects the normal fuel supply of the diesel engine, causing the pressure in the low-pressure oil circuit to build up slowly, resulting in less fuel supply to the cylinder, low fuel supply pressure, poor atomization, and low diesel engine power. It can usually return to normal after solving the problem of clogged fuel system pipes and filters. In addition, a faulty fuel pump can cause the same phenomenon. You can judge whether the oil transfer pump is working normally by checking the diesel oil line pressure (>5bar) and flow rate (>8L).
Sijesyon: Lè motè dyezèl la kòmanse apre yon entèval long, li pran yon sèten kantite tan pou konstwi presyon nan kous lwil oliv ba-presyon. Si li imedyatman antre nan operasyon lou-chaj, pouvwa pwodiksyon an pral ba. Li rekòmande ke ekipman an kòmanse travay nan zòn nan vitès mwayen san chaj pou apeprè 20 segonn apre demaraj.
