作者们试验研究了二环制活塞中油环的轴向窜动及其影响,并且计算出油环刮片的瞬时窜动,根据试验能够定量的确定油环轴向窜动。另外,通过对机油消耗量的连续测量表明;在压缩行程期间较重的刮片会使机油消耗量增大,因此,减轻刮片重量和提高第二道环岸压力,能够有效地降低机油消耗量。 The authors experimentally studied the axial run-up of the oil ring in a two-ring piston and its effect, and calculated the instantaneous run-out of the oil ring wiper blade, which determined the axial play of the oil ring quantitatively. In addition, continuous measurement of oil consumption indicates that heavier wipers increase oil consumption during the compression stroke, thereby reducing oil consumption due to reduced wiper weight and increased second bank pressure the amount.
