Deutz diesel cav qeeb qeeb heev

Fault phenomenon: Lub cav diesel pib ib txwm thiab ua haujlwm ib txwm ntawm qhov siab thiab qis qis qis. Thaum cov khoom siv nyob rau hauv qhov hnyav, qhov ceev poob siab, qhov ceev poob mus txog 1100 ~ 1300rpm, thiab lub tsheb ceev kuj tseem qis, tab sis nws rov qab mus rau qhov qub tom qab ua haujlwm rau lub sijhawm luv luv.

Cov txheej txheem daws teeb meem: Tshawb xyuas cov roj system siab thiab ntws, thiab pom tias lub siab thiab ntws yog ob qho tib si qis. Tshawb xyuas cov roj kav dej thiab cov lim dej, thiab pom tias muaj cov khoom txawv teb chaws daig hauv tes roj twj. Tom qab tshem nws, nws rov qab mus rau qhov qub.

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).

Cov lus qhia: Thaum lub tshuab hluav taws xob pib pib tom qab lub sijhawm ntev, nws yuav siv sij hawm qee lub sij hawm los tsim kom muaj siab nyob rau hauv cov roj hluav taws xob qis. Yog hais tias nws tam sim ntawd nkag mus rau hnyav-load ua hauj lwm, cov zis hwj chim yuav tsawg. Nws raug pom zoo tias cov cuab yeej pib ua haujlwm hauv thaj chaw nruab nrab-ceev tsis muaj kev thauj khoom li 20 vib nas this tom qab pib.
