在毛主席的无产阶级革命路线指引下,各条战线都取得了伟大的胜利。我国内燃机制造工业在进一步提高产品质量的基础上,正朝着高增压、高效率方向迅速发展。随着柴油机平均有效压力和速度的提高,作用在活塞上的机械负荷和热负荷也不断地增大;这就对活塞的材料、设计和制造工艺提出了新的要求。例如在材料上寻找耐热、耐磨、导热好、膨胀小、热稳定性好的合金;在结构上采用了镶顶、活
Under Chairman Mao’s proletarian revolutionary line, all fronts have achieved great victories. China’s internal combustion engine manufacturing industry to further improve product quality, based on the direction of high pressurization, high efficiency and rapid development. As the average effective pressure and speed of the diesel engine increase, the mechanical and thermal loads acting on the piston also increase. This puts forward new requirements on the material, design and manufacturing process of the piston. For example, looking for heat-resistant materials, wear-resistant, good thermal conductivity, small expansion, good thermal stability of the alloy; in the use of the structure of the top, live
