(Summary description)
　　The normal consumption of diesel engine oil generally accounts for 0.7~2.5% of diesel consumption, if it exceeds this number of times, it indicates that the diesel engine consumes too much oil. Reasons for excessive consumption: first, the oil cylinder liner piston group sneaks into the combustion chamber; Second, the oil rushes into the combustion chamber along the gap between the valve and the conduit; The third is to leak oil from other seals.Consumption reduction measures:(1) Replace with new energy-saving piston rings, especially oil rings, to improve oil scraping power and prevent oil from entering the combustion chamber; After the cylinder liner is worn, it should be repaired in time, and the cylinder liner, piston ring and piston can be replaced if necessary.(2) Always keep the crankcase negative pressure or zero pressure to prevent positive pressure. Single-cylinder diesel engines can be equipped with negative pressure valves, and multi-cylinder diesel engines can be equipped with filter vents.(3) The valve guide should be replaced in time after wear to prevent the oil from entering the combustion chamber along the valve stem.(4) The use of sealing adhesive can play the role of sealing, leakage-proof, fastening and plugging the gap, so as to achieve the purpose of preventing leakage of oil. If the oil seal is damaged, replace it in time.(5) Change the oil regularly. When the oil becomes thin or aging and loses its lubricating effect, replace the new oil in time.
