看了一篇《一槽双环的探讨》文章后,我突发奇想,能否在不扩槽的情况下实现“一槽双环”呢?如果将现行的活塞环厚度减少一半,不也可以达到“一槽双环”的目的吗? 抱着试试看的想法,我在一辆旧NF125A车上进行了试验。首先将换下来的旧环用手工磨薄。原环的厚度是1.2毫米的梯形环。只磨底部,保留另一面梯形形状,将厚度磨到0.6毫米。这样,两环叠合后的厚度刚好1.2毫米。叠合时底部相对,将缺口大的另一面朝向环槽岸,在避开气口的位置加
After reading an article titled “One Groove Bicyclic Discussion,” I suddenly wondered if we could achieve a “one-slot double-loop” without expanding the slot. If the thickness of the existing piston ring is reduced by half, it can not be achieved “One Slot Bicycles” for the purpose? With the idea of trying it out, I tested it on an old NF125A car. First, replace the old ring by hand thinning. The original ring thickness is 1.2 mm trapezoidal ring. Only the bottom of the mill, retaining the other side of the trapezoidal shape, the thickness of 0.6 millimeters. In this way, the thickness of the two rings overlap just 1.2 mm. Laminated at the bottom of the relative, the other side of the notch toward the ring groove shore, to avoid the position of the air port plus
