(1)柱塞套的定位螺钉应符合要求，不可过长，否则会使柱塞套在泵体内被顶歪，影响柱塞在套内灵活运动，加速偶件磨损，还会使螺钉与回油孔间隙过小，甚至堵住回油孔，不能及时回油，造成发动机“飞车”。(2)柱塞套定位螺钉不应拧得过紧，否则会使套筒变形，卡住柱塞。其安装要求是：在未装出油阀紧座时，拧紧定位螺钉后，柱塞套在泵体内能小距离上下灵活移动，但不产生转动。(3)切不可漏装定位螺钉的铜垫片，并且要此处密封，否则会造成漏油，还会导致空气进入喷油泵，使发动机运转不稳定。
4、出油阀座的垫片不得漏装、损坏，而且要求平整：
(1)出油阀座的高压密封紫铜垫和低压密封橡胶垫，装前必须仔细检查，要求完好无损，更不得漏装，否则会造成高压油腔与低压油腔相通，致使油泵不能正常工作。(2)安装出油阀紧座时，拧紧力距必须适度。拧紧以后柱塞在柱塞套内任何位置都能灵活运动，不产生局部卡滞现象。(3)垫片必须平整。如垫片凹凸不平或有皱折，出油阀紧座拧紧后，柱塞套易单边受力，加速柱塞偶件磨损。
5、按规定要求，正确调整好供油提前角。
1、进气压力温度传感器损坏现象：
ON档，发动机故障灯常亮;原地缓踩油门时冒少量黑烟，急加速冒大量黑烟；发动机没劲；故障码：P01D6（进气压力传感器电压低于下限）原因分析：进气压力信号异常，ECU无法接收到正确的进气量信息，导致喷油量也随之异常，则燃烧不充分，发动机没劲，在加油过程中冒黑烟。线束连接出问题和传感器失效都会导致该故障。解决措施：检查进气压力温度传感器。

Formerly established by the Machinery Ministry of China in 1989 and held every other year since then, BICES has grown from what was originally a domestic new products and new technology show to be one of leading international trade fairs for construction, building and mining machinery in Asia with over 1,000 exhibitors and more than 150,000 visitors from China and overseas markets. Focusing on PODGK po@china-lutong.net the theme ‘Digital, Efficiency, Green and Reliable’, BICES 2023 will present high-end, intelligent, and new green technologies, products and services for the industry.
BICES is a world leading exhibition in fields of construction machinery, building material machinery, mining machinery and commercial vehicles. You are welcome to join as either exhibitors or visitors to explore the huge business opportunities awaiting you at BICES 2023. If you’re attending, please stop by and see us at booth E1022 in Hall E1. I hope to see you soon!
2、水温传感器损坏现象：
ON档，发动机故障灯常亮；ON档水温始终显示大值120℃；发动机限扭、没劲；故障码：P003D（水温传感器电压低于下限值）原因分析：水温传感器失效，ECU检测到水温传感器输出信号不可信时使用替代值，ECU出于保护发动机的目的，发动机的扭矩。解决措施：检查水温传感器。
