随着技术的发展,国家排放法规日益严格,非公路用电控发动机得到越来越广泛的应用。发动机作为工程机械核心部件,其稳定性和可靠性显得尤为重要。一旦发动机出现诸如掉速等问题,将不仅仅影响工程进度,可能还会带来经济损失。本文从1台调试状态的挖掘机故障入手,详细阐述了电控发动机燃油系统故障排除的过程及方法。某中型液压挖掘机在调试阶段时,出现低速 With the development of technology, the national emission regulations are becoming more and more strict, and non-road electric control engines are more and more widely used. Engine as a core component of construction machinery, its stability and reliability is particularly important. Once the engine problems such as speed off, will not only affect the progress of the project, may also bring economic losses. This article starts from a debugging state of the excavator fault, elaborated the process and method of troubleshooting of the fuel system of the electronically controlled engine. A medium-sized hydraulic excavator in the commissioning phase, low speed
