Determination of fuel consumption:
The consumption of oil is measured by the oil level gauge (1) and measured by the fuel consumption when maintaining a certain oil level.
Therefore, the oil level check to determine the oil consumption is to be accurately performed. Excavator spare parts
Check the oil level to avoid the change of oil quantity and the error of oil circulation, check the intermittent time at the start of construction.
The engine that is replenished from the cylinder head is inspected after about 30 minutes after replenishment. Komatsu spare parts
Oil consumption:
The oil consumption is determined by the size of the engine, working conditions, etc.
Also, the length of working hours, temperature, external pressure (highland work), etc., will also change the consumption of oil.
In addition, when the piston ring openings overlap, etc., it will also cause a temporary increase in consumption. Komatsu excavator spare parts
Oil consumption rate:
The consumption of oil will vary greatly depending on the model and working conditions. Therefore, it is difficult to judge whether the consumption is abnormal or not by "how many L is consumed in one day".
In order to correct the change of the type of engine (the size of the engine) and the working conditions, the consumption of the oil is expressed by the relative fuel consumption and how much oil is consumed, that is, the "oil consumption rate".
Oil consumption (L)
Oil consumption rate: ————×1000%
Fuel consumption (L)
Determination of oil consumption rate:
★ In addition to accurately checking the oil level, accurately measure the (oil) consumption, and accurately determine the fuel consumption.
★The consumption of oil is affected by many conditions, so it is necessary to judge according to the measurement result of long time (need to be about 1 month).
When the consumption is greatly increased, it must be processed in advance.
The new car (working time is less than 500H) has a tendency to increase consumption due to the running-in relationship of the sliding surface.
The engine with a turbocharger, the oil circulation to the turbocharger, etc., the oil consumption tends to increase.
Long-term working engine due to the wear of the piston ring and cylinder liner, the oil consumption rate deteriorates (according to the degree of wear)
The engine with light load and high speed operation, although the fuel consumption is small, the circulation of oil does not change, and because the combustion pressure does not increase, the amount of oil brought back by the piston ring becomes larger, and the oil consumption rate increases.
★ When judging the consumption rate of oil, it is necessary to combine all of the above factors and judge that it is necessary to pay attention to the fact that if it is judged numerically, it sometimes produces an erroneous treatment method. Also, as a general standard, the same type of machine Compared to
More than 0.5 -1. 0% → Be careful
More than 1.0 to 2% → Judging as many
More than 2% → consumption is large or abnormal
