在柴油发动机燃烧过程中，会产生碳烟颗粒，这些碳烟颗粒要么被排放到大气中，要么被发动机的润滑剂吸收。被烟灰污染的润滑剂已被证明会产生大量的发动机磨损。烟灰相关磨损的主要机制是通过磨损，但是，在润滑剂中烟灰含量水平增加时，可能发生接触饥饿，这可能进一步增加磨损。高浓度的烟灰会增加局部酸性水平，并且在高温和挥发性气体共存的活塞周围，也可能发生腐蚀。在本文中，目前的理解，由于碳烟污染和以前的研究进行的发动机磨损。本文还讨论了碳烟的形成及其在发动机内的一般影响（包括摩擦和效率），以及其他问题，包括过滤或去除，对润滑剂的影响，发动机设计和操作，以及未来的工业目标和与碳烟污染相关的技术。
During the diesel engine combustion process, soot particles are produced and are either exhausted into the atmosphere or absorbed by the engine's lubricant. Soot-contaminated lubricant has been shown to produce significant amounts of engine wear. The main mechanism of soot-related wear is through abrasion, but, at increased levels of soot content in the lubricant, starvation of the contact can occur, which can increase wear further. High concentrations of soot can increase the local acidic level and, around the piston where high temperatures and volatile gases coexist, corrosion may also occur. In this paper, the current understanding of engine wear due to soot contamination and the previous research performed is reviewed. The paper also discusses soot formation and its general effects within the engine (including friction and efficiency), as well as other issues including filtration or removal, effects on the lubricant, engine design and operation, and future industry targets and technologies related to soot contamination.
