基于FPS传感器的润滑油品质车载监测系统

The Vehicle-mounted Inspecting System for Lubricant Oil Quality Based on Fluid Property Sensor

使用FPS油品传感器测量柴油机润滑油的黏度和介电常数,并将其标准化后建立润滑油的实车监测模型。使用该模型对某重型柴油机润滑油进行监测,所测量结果与使用石油产品运动黏度测定仪测量的结果一致。因此,采用该模型可监测柴油机润滑系统的技术状况,为实车机油的在线监测和按质换油提供了一种新方法。

The dynamic viscosity and dielectric constant of diesel engine lubricating oil were determined by FPS lubrica- ting oil quality sensor and were standardized. A vehicle monitoring model of lubricating oil was built and was used to moni- tor a heavy diesel engine lubricating oil. The monitored results are in accord with those tested using kinematic viscosity tester of petroleum product. So, this model can be applied to monitor the technical condition of diesel engine lubricating system, and a new way is offered to monitor the vehicle lubricating oil and change the lubricating oil according to its quality.
