SBIR Phase I: Versatile In-Situ Engine Lubricant Health Sensor

这项小型企业创新研究（SBIR）第一阶段项目将开发一种创新的、具有成本效益的油质传感器，该传感器可以检测发动机机油何时以及如何降解，作为智能发动机健康监测系统的组成部分。电流传感器通常只适用于特定类型的油或特定类型的降解机制（例如金属碎片或水污染），或者从发动机运行时间等信息间接推断油的状况。目前，还没有一种单一的、具有成本效益的机载传感器能够识别来自不同来源的石油降解。通过在单个传感器上集成一套传感功能，新型传感器将允许在线监测各种模式的油降解。这项研究的更广泛/商业影响是开发车载传感器，可以持续监测发动机的健康状况，并在需要维修时向操作员/驾驶员发出警报。智能发动机将确定其最佳使用间隔，并利用先进的油质传感器提供的信息，避免因频繁换油而增加成本，或因不频繁换油而增加发动机磨损。一个可靠的、经济的机载油况传感器将有利于发动机原始设备制造商，因为他们可以通过降低客户的生命周期成本来获得竞争优势，并使最终用户受益，因为他们的操作和维护成本降低了。

This Small Business Innovation Research (SBIR) Phase I project will develop an innovative, cost-effective, oil quality sensor that can detect when and how engine oil becomes degraded, as an integral part of a smart engine health monitoring system. Current sensors typically work only with a specific type of oil or a specific type of degradation mechanism (e.g. metal fragments or water contamination) or indirectly infer oil condition from information such as engine run time. Presently no single, on-board, cost-effective sensor that will identify oil degradation from different sources is available. The new sensor will allow on-line monitoring to detect various modes of oil degradation by incorporating a suite of sensing capabilities on a single sensor. The broader/commercial impacts of this research are developments to on-board sensors that can continuously monitor engine health and alert the operator/driver when service is required. A smart engine will determine its optimal service interval and with information provided by the advanced oil quality sensor can avoid added cost of too frequent oil changes or increased engine wear from too infrequent oil changes. A reliable, cost-effective on-board oil condition sensor will be beneficial to the engine original equipment manufacturers as they can gain a competitive edge by reducing lifetime cost to their customers, and benefit the end users as their operation and maintenance costs are reduced.
