Handling and solving method of fuel oil consumption increase of excavator

Anhui excavator excavator is added to tell you: fuel consumption is a common question is wrong in the excavator, excavator digging machine burning oil refers to the fuel consumption than the paragraph with the same type excavator digging machine found high fuel consumption in the work, and work with a black smoke phenomenon, burning oil is oil in incineration.

Fault classification:

One, the excavator fuel consumption anomaly increases, more fuel consumption;

Two, the exhaust black smoke;

Excavator burning oil reason:

1, the lower exhaust work digging machine black smoke, and the investigation of oil consumption also more than usual, that burning oil may be digging machine, piston ring wear, valve gap, valve guide, gap piston device fault reasons.

Void 2, cylinder liner and piston is too large, perhaps the oil piston ring stuck or cracking.

3, if the burning oil appearance occurred after accompanied by exhaust oil appearance, is likely to be severe cracking formation may wear piston rings.

4, burning oil, if the exhaust is not very serious, may be the turbocharger seal is not strict formation, at the moment, it is argued that the two tubes of the turbine is removed to see if there is no oil, if there is oil to clarify the turbocharger.

5, other, engine valve seal is bad, it will form an excavator burning oil surface.

6, extra oil.

Anhui excavator tells you: common disposal method of oil burning engine oil:

1, check the oil is not too much.

2, check the turbocharger turbine, the intake and exhaust two hose release, normal should be dry. Found that there is oil on the turbine may have a doubt about the oil from the turbine to the exhaust pipe.

3, in the morning just to play a note when the exhaust pipe, if black smoke and a clear oil smell is likely to be the turbine oil.

4, check the engine exhaust gas pipe weight is not heavy, normal should see a light smoke, if the gas is very heavy, severe and even drop oil, the repair engine.

5, the other, the turbine oil channeling oil is generally less ferocious, should be the main point of view of the exhaust pipe.
