使用一台装有透明玻璃气缸的改装发动机作为拖动装置,研究活塞内侧的油环槽回油孔附近的结构、油环刮片的切口间隙尺寸和第一道环间隙形状对机油窜油的影响。结果表明,通过使用在活塞内侧回油孔下部安装盖的活塞,经优化的上、下刮片间隙尺寸和采用特殊切口(三角阶梯形切口)的第一道环与标准活塞和标准活塞环组相比,可降低不希望有的机油窜油量,此外,组合使用改进的活塞与活塞环组可大大降低讨厌的机油窜油量。
Using a modified engine equipped with a transparent glass cylinder as the actuator, the structure near the oil return groove in the oil ring groove on the inner side of the piston was studied. The notch clearance size of the oil ring blade and the gap shape of the first ring gap interfered with the oil influences. The results showed that by using the pistons with caps mounted on the underside of the return hole in the piston, the optimized upper and lower blade clearance dimensions and the first ring with a special cut (triangular step cut) were used with standard and standard piston ring sets Compared to reduce undesirable oil trampoline, in addition, the combination of improved piston and piston ring group can greatly reduce the nasty oil trampoline.
