反复研究实验证明:柴油机使用钢带组合油环是非常必要的。钢带组合油环,过去由于内衬簧凸缘和刮片内圆表面的磨损,使油耗恶化。现这种磨损可由增大内衬簧凸缘与刮片内圆表面的接触面积,或适当选择刮片内圆表面的镀层厚度来解决。文章提供了行车30万公里(使用寿命2000小时)的钢带组合油环所需要的接触面积和必需的镀层厚度。新开发的组合油环具有良好的控油性能,83年已用于丰田汽车发动机。
Repeated research and experiments show that: Diesel oil ring combination is very necessary. Steel band oil ring, in the past due to the inner wall of the spring and scraper blade inner wear and tear, so that deterioration of fuel consumption. This wear can be increased by the liner spring flange and the inner surface of the blade contact area, or appropriate selection of the inner surface of the blade coating thickness to solve. The article provides the contact area and the required coating thickness for a strip oil ring 300,000 kilometers (2,000 hours of service life). Newly developed combination of oil ring has good oil control performance, 83 years has been used for Toyota Motor Engine.
