Development of Ultrasonic Oil Condition and Level Sensors for Use with NEXCEL

项目目标：该项目的目标是开发一种超声波传感器，可以预测NEXCEL油槽内润滑剂的状态并长时间测量其液位。在此应用中使用超声波将极大地帮助油电池的设计，因为它将消除跨越细胞壁的通道的必要性，导线连接到内部安装的油传感器，从而消除潜在的泄漏路径和故障模式。目的：探讨超声传感与现有液位传感方法的协同作用。识别传感器参数和波浪条件，以在NEXCEL内实现最准确的液位测量。当油降解时，确定最适合测量的特性，以及哪种传感器类型更有能力进行这些测量，确定可以测量哪些润滑油参数来确定油的状况。确定最佳的超声波脉冲方法，通过NEXCEL细胞壁实现润滑剂状态的测量。在NEXCEL基座上创建第二个原型传感器，它将与NEXCEL底部有足够的接触。在可能的情况下调查并尽量减少变化-温度，尺寸，传感器之间的比较（均匀负载和粘合剂粘合层）等等。使用符合NEXCEL目标要求的低成本部件构建原型超声波传感器。在NEXCEL车队或配备NEXCEL系统的发动机测力仪上进行测试开发。潜在的应用和好处：NEXCEL是一种新颖而卓越的油底壳，旨在减少二氧化碳排放，确保快速简便的机油和过滤器更换，安全收集和回收机油，确保精确的机油-发动机匹配，最后，它有助于油更快地预热，停止长时间的冷启动。该项目旨在增加传感器，帮助预测油位和状态，从而更好地使用机油，及时更换机油，延长发动机部件的使用寿命。

Project Aim:The aim of this project is to develop an ultrasonic sensor that can predict the state and measure the level of the lubricant inside the NEXCEL oil cell over an extended period. The use of ultrasound for this application will greatly help with the design of the oil cell because it will remove the necessity to have a channel across the cell wall, for wires leading to an internally mounted oil sensor, thus removing a potential leak path and failure mode.Objectives: Explore the synergy of ultrasonic sensing with current level sensing methods. Identify sensor parameters and wave conditions to achieve most accurate level measurement within the NEXCEL. Identify the most suitable properties to measure as oil degrades and which sensor type is more capable at taking those measurements Identify which lubricant parameters can be measured to determine oil condition. Determining the best ultrasonic pulsing method to achieve measurement of the lubricant state through the NEXCEL cell wall. Create second prototype sensor on the NEXCEL dock, which will have sufficient contact with the bottom of the NEXCEL. Investigate and minimise variability where possible - Temperature, dimensions, comparisons between sensors (uniform loads and adhesive bonding layers) and more. Build prototype ultrasonic sensors using low cost parts that adhere to the requirements of the NEXCEL objectives. Test developments on the NEXCEL vehicle fleet or an engine dynamometer fitted with the NEXCEL system.Potential Application and Benefits:NEXCEL is a novel and superior oil sump that has been designed to reduce carbon dioxide emissions, ensure quick and easy oil and filter changes, safely collect and recycled oil, ensure a precise oil-engine match and finally, it helps the oil to warm up more quickly, stopping prolonged cold starts. This project aims to add sensors that will help predicted oil level and state, which in turn will lead to better use of engine oil, timely oil changes and the longer life of engine components.
