本文简要讨论了与现代柴油机可靠性有关的气缸组零部件——活塞、活塞环和气缸套的状况,包括在降低费用的条件下,为提高寿命所采取的理论上的、柴油机和装配方面的试验技术。详细地叙述了运用问题的典型特征和从设计及费用方面解决这些问题的办法。本文还列举了应用设计价值分析在不损害可靠性条件下降低零部件费用的实例。 This article briefly discusses the condition of the cylinder block components - pistons, piston rings and cylinder liners - that are relevant to the reliability of modern diesel engines, including the theoretical and theoretical considerations of diesel engine and assembly at lower costs, Test technology. Described in detail the typical characteristics of the use of the problem and the solution to these problems in terms of design and cost. This article also lists examples of application design value analysis to reduce component costs without compromising reliability.
