Fuel System Fuel Filter Differential Pressure - Check
必须安装燃料滤清器压差表，以便确定何时需要进行燃料滤清器的保养。 此仪表及燃气滤清器由用户提供。
燃气滤清器压差表指示燃气滤清器燃气进口侧和燃气出口侧之间的燃气压差。 当燃气滤清器堵塞时，压差会增加。
运行发动机至额定转速和正常工作温度。 检查燃气滤清器的压差。 燃气滤清器的保养取决于燃气系统的压力。
- 对于低压气燃气系统，在燃气滤清器压差达到
1.7 kPa (0.25 psi) 时保养燃气滤清器。 - 对于高压气燃气系统，在燃气滤清器压差达到
34 kPa (5 psi) 时保养燃气滤清器。
有关具体说明，请参阅专门说明书, SEHS9298, "燃气滤清器的安装和保养"。 请咨询您的卡特彼勒代理商以获得帮助。
