Nosozlik hodisasi: dizel dvigatel an'anaviy tarzda ishga tushadi va yuqori va past bo'sh tezlikda normal ishlaydi. Uskunalar og'ir yuk ostida bo'lsa, tezlik jiddiy ravishda pasayadi, tezlik taxminan 1100 ~ 1300 rpm ga tushadi va avtomobil tezligi ham past bo'ladi, lekin qisqa vaqt ichida ishlagandan keyin normal holatga qaytadi.
Muammolarni bartaraf etish jarayoni: Yoqilg'i tizimining bosimi va oqimini tekshiring va bosim va oqimning ikkalasi ham past ekanligini aniqlang. Yoqilg'i tizimining quvurlari va filtrlarini tekshiring va qo'l moy nasosida begona moddalar tiqilib qolganligini aniqlang. Tozalashdan keyin u normal holatga qaytadi.
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).
Taklif: Dizel dvigatel uzoq vaqt oralig'idan so'ng ishga tushirilganda, past bosimli yog 'devrida bosim hosil qilish uchun ma'lum vaqt kerak bo'ladi. Agar u darhol og'ir yuk bilan ishlashga kirsa, chiqish quvvati past bo'ladi. Uskunani ishga tushirgandan so'ng taxminan 20 soniya davomida yuksiz o'rtacha tezlik zonasida ishlashni boshlash tavsiya etiladi.
