随着现代内燃机效率的提高,发动机轴承面临的挑战也日益增多。例如,起动-停车系统使曲轴和轴瓦经历混合摩擦阶段的循环数增加,具体取决于行驶状态。Federal-Mogul公司在颗粒增强聚酰胺亚胺的基础上推出一种新型减摩层,它能防止金属减摩层在这种条件下可能会出现的磨损。 With the improvement of the efficiency of modern internal combustion engines, the challenges of engine bearings are also increasing. For example, the number of cycles that a start-stop system subjects a crankshaft and a bush to hybrid friction stages increases, depending on the driving conditions. Federal-Mogul introduced a new anti-friction layer based on particle-reinforced polyamideimides, which prevents wear on the metal anti-friction layer under these conditions.
