Optical diagnostic tools have advanced significantly in recent years in industrial and academic facilities for non-intrusive and effective methods. A high-speed camera is an essential tool for advanced research activities at the Clean Combustion Engine Laboratory of the University of Windsor. Our research focuses on the renewable fuel and clean combustion process for current and future engines, from autoignition of high reactivity fuels such as diesel and dimethyl ether, to spark ignition of low reactivity air-fuel mixture, such as natural gas, gasoline and ethanol. Several constant-volume combustion vessels, a rapid compression machine (RCM), and a single-cylinder research engine equipped with optical diagnostic tools are employed to study the ignition and dynamic combustion control process. As clean combustion engines continue to be the powerhouse of the transportation in the next 50 years, government regulations and OEM pursuits for customer needs of highly-efficient, renewable fueled, and ultra-low clean engines are the driving force for advanced combustion control and diagnostic research. This high-speed camera plays an essential role for the precision diagnostic research on transient events of a combustion process which outcomes will be not only in the mechanism studies of advancing scientific knowledge but also the smart control of the combustion towards renewable and sustainable fuel-flexible clean engines. The diagnostic parameters obtained through the proposed equipment will provide with the crucial information for the highly efficient engine combustion control, including hybrid vehicles and autonomous driving lookup tables for optimized engine operating modes. Through the collaborative industrial projects in the past years, many research outcomes resulted from the use of the high-speed camera have led to recent patents on ignition innovations that attracted our partners to use in their clean engine advancement. Both PI and co-PI have the expertise in clean engines, combustion diagnostics and emission control using optical diagnostics and combustion simulation. HQPs will learn image processing, optical manipulation of specific filters to identify certain light sources or emissions of light, and the correlation to combustion process and flow field principles. As optical techniques are widely used in industry and research labs, the knowledgeable engineers in this area are in demand for imaging analysis and diagnostic methodologies for calibration and efficiency improvements. HQPs in the research team will apply the advanced knowledge in high-tech diagnostic system for ion-current, corona plasma and ultra-high pulsation LED light source to develop the best-practical approaches of solving engineering problems.

近年来，光学诊断工具在工业和学术设施方面已经取得了显着发展，用于非侵入性和有效方法。高速相机是温莎大学清洁燃烧引擎实验室高级研究活动的重要工具。我们的研究着重于当前和未来发动机的可再生燃料和清洁燃烧过程，从高反应性燃料（如柴油和二甲基）等高反应性燃料，到引发低反应性空气燃料混合物（例如天然气，汽油，汽油和乙醇）的点火。几个恒定体积燃烧容器，快速压缩机（RCM）以及配备了光学诊断工具的单缸研究引擎来研究点火和动态燃烧控制过程。 随着干净的燃烧发动机在未来50年内继续成为运输的强国，政府法规和OEM追求对高效，可再生能源的客户需求和超低清洁发动机的需求是高级燃烧控制和诊断研究的驱动力。这款高速摄像机对于燃烧过程的短暂事件的精确诊断研究起着至关重要的作用，结果不仅在推进科学知识的机制研究中，而且还将是对燃烧可再生且可持续的燃料燃料可燃烧的清洁引擎的智能控制。通过拟议设备获得的诊断参数将提供高效的发动机燃烧控制的关键信息，包括混合动力汽车和自动驾驶查找表，用于优化的发动机操作模式。通过过去几年的协作工业项目，由于使用高速相机的使用而产生的许多研究成果已为点火创新提供了最近的专利，吸引了我们的合作伙伴在清洁发动机的前进中使用。 PI和CO-PI都具有使用光学诊断和燃烧模拟的清洁发动机，燃烧诊断和排放控制方面的专业知识。 HQP将学习图像处理，对特定过滤器的光学操纵以识别某些光源或光的发射，以及与燃烧过程和流场原理的相关性。由于光学技术广泛用于行业和研究实验室，因此该领域知识渊博的工程师需要进行成像分析和诊断方法，以进行校准和提高效率。研究团队中的HQP将应用高科技诊断系统中的高级知识，以解决离子电流，电晕等离子体和超高脉动LED光源，以开发解决工程问题的最佳实践方法。
