一、序言本文详述并讨论了机车柴油机的辅助系统以及它们所带有的保护装置。安装在这些系统上的保护装置旨在一旦辅助系统或柴油机产生故障时保护柴油机。机车柴油机的这些辅助系统为柴油机有效且可靠地产生动力创造了条件。这些辅助系统即指冷却、润滑、燃油和空气等系统,见图1。自一九五四年以来,机车功率已经从1950制 I. Preface This document details and discusses the auxiliary systems of locomotive diesel engines and the protective devices they carry. The protection installed on these systems is designed to protect the diesel engine in the event of a malfunction of the auxiliary system or the diesel engine. These auxiliary systems for locomotive diesel engines create the conditions for effective and reliable diesel engine power generation. These auxiliary systems refer to cooling, lubrication, fuel and air systems, see Figure 1. Since 1954, locomotive power has been from the 1950 system
