Il-magna diesel Deutz tnaqqas serjament

Fenomenu tal-ħsara: Il-magna diesel tibda b'mod normali u taħdem b'mod normali f'veloċitajiet idle għoljin u baxxi. Meta t-tagħmir ikun taħt tagħbija tqila, il-veloċità tinżel serjament, il-veloċità tinżel għal madwar 1100 ~ 1300rpm, u l-veloċità tal-vettura hija wkoll baxxa, iżda terġa 'lura għan-normal wara li taħdem għal perjodu qasir ta' żmien.

Proċess ta 'soluzzjoni ta' problemi: Iċċekkja l-pressjoni u l-fluss tas-sistema tal-fjuwil, u sib li l-pressjoni u l-fluss huma t-tnejn baxxi. Iċċekkja l-pipelines tas-sistema tal-fjuwil u l-filtri, u ssib li hemm materja barranija mwaħħla fil-pompa taż-żejt tal-idejn. Wara li tnaddafha, terġa 'lura għan-normal.

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).

Suġġeriment: Meta l-magna diesel tinbeda wara intervall twil, tieħu ċertu ammont ta 'żmien biex tinbena pressjoni fiċ-ċirkwit taż-żejt bi pressjoni baxxa. Jekk immedjatament tidħol f'operazzjoni ta 'tagħbija tqila, il-qawwa tal-ħruġ tkun baxxa. Huwa rakkomandat li t-tagħmir jibda jaħdem fiż-żona ta 'veloċità medja mingħajr tagħbija għal madwar 20 sekonda wara l-istartjar.
