电喷发动机燃油压力调节器运行状况及油压高低直接关系着燃油喷射的精确度,同时对发动机工作性能也有一定影响,其影响力一般较为隐秘,容易被忽略,从而引发一系列的故障。发动机燃油压力调节器虽然结构简单,然而其在电喷发动机中所发挥的作用则较大,是一个较为复杂的压力控制过程。就目前多个汽车维修案例来看,汽车很多故障都与发动机燃油压力调节器故障存在或多或少的联系,基于发动机燃油压力调节器故障的影响力,本文结合一起电喷发动机燃油压力调节器故障实例对其故障诊断与排除措施展开了论述分析。
EFI engine fuel pressure regulator operating conditions and the level of fuel pressure is directly related to the accuracy of fuel injection, while the engine performance also has a certain impact, its influence is generally more hidden, easily overlooked, causing a series of failures. Although the structure of the engine fuel pressure regulator is simple, its role in the EFI engine is larger, which is a more complicated pressure control process. At present, many car repair cases, many problems with the engine fuel pressure regulator failure is more or less linked, based on the impact of the engine fuel pressure regulator failure, combined with an EFI engine fuel pressure regulator Fault examples of its fault diagnosis and troubleshooting are discussed and analyzed.
