缸套和水套壁裂纹、工作表面极限磨损及擦伤、冷却水沿密封处泄漏等,这是造成Д100系列柴油机缸套报废的主要故障。每年由于上述故障造成的缸套更换率,约占运用数的17%。在造成柴油机机破的全部故障中,由缸套损坏所引起的约占20％。对运用中内燃机车故障情况进行分析后表明,10Д100型柴油机缸套的损坏比2Д100型柴油机约多1倍。 Cylinder liner and water jacket wall cracks, the work surface of the extreme wear and abrasion, cooling water leak along the seal, which is caused Д100 Series diesel cylinder liner scrapped the main fault. Each year due to the above failure caused by the liner replacement rate, accounting for about 17% of the number. About 20% of the total failure caused by the diesel engine is caused by cylinder liner damage. Analysis of the failure of diesel locomotives under operation shows that the damage of 10Д100 diesel engine cylinder liner is about one time more than that of 2Д100 diesel engine.
