摘要柴油机喷油器内部沉积物现象在几个关键燃料市场中是一个日益严重的问题，越来越多的汽车制造商报告了该领域的问题。本文将介绍阿夫顿化学公司对这些矿床来源的深入调查。阿夫顿能够识别并将这些矿床归类为两类：羧酸盐和有机酰胺。一个系统的解决问题的方法适用于这些存款，成功地确定了各自的来源。本文将讨论用于识别沉积物的分析技术，以及为确认其来源假设而开发的发动机测试的细节。将审查发动机试验的结果，以复制现场问题，并将讨论解决这一日益严重的服务问题的建议。
ABSTRACT The phenomenon of diesel injector internal deposits is a growing issue in several key fuel markets, with an increasing range of automotive vehicle manufacturers reporting problems in the field. This paper will describe Afton Chemical Corporation’s in-depth investigations into the sources of these deposits. Afton was able to identify and categorize these deposits as belonging to two groups: Carboxylates and Organic Amides. A systematic problem solving approach was applied to these deposits which successfully identified their respective sources. This paper will discuss the analytical techniques used to identify the deposits, as well as details of the engine tests developed to confirm the hypotheses for their sources. Results of the engine tests to replicate the field issues will be reviewed and recommendations for solutions to this growing in-service problem will be discussed.
