摘　　要：介绍汽车电动燃油泵的组成和工作原理,分析常见的电动燃油泵失效模式,如无燃油供应、泵油压力不足、供油压力偏低及供油量不足、输油管路无残余压力、供油不足时燃油泵发出尖叫声等失效模式。The composition and work principle of the automotive eleetronic fuel pump was introduced. The familiar failure modes of auto- motive electronic fuel pump were analyzed, such as no fuel power, low pump fuel pressure and fuel supply shortage, no remnant pressure in filel pipeline, fuel pump screaming due to insufficient fuel supply, etc.

关 键 词：电动燃油泵 失效模式 故障分析
