Carbon emissions from diesel engines are a major source of automotive pollution and are harmful to the environment. It is known that the diesel combustion exhaust releases carbon soot particle, which is partially mixed in operational and used engine oil. Under the Paris Agreement, Canada is committed to reducing its greenhouse gas emissions (GHG) by 30% below 2005 levels by 2030. To combat climate change by reducing the carbon footprint, the objective of the proposed research project is to investigate and develop a clean, high power efficiency and eco-friendly microwave technology for processing carbon soot in the operational and used engine oil in automotive application. In particular, the proposed project will develop a novel high power density power conversion circuit that is capable of generating microwave energy (in the range of thousands of MHz) efficiently for use in carbon soot elimination. In a microwave energy generator, the key element is the high voltage power supply. Hence, power conversion circuit with a very high voltage conversion ratio is required. The proposed power conversion circuit will feature very large step-up voltage conversion ratio with loss-less switching behavior to maximize the circuit efficiency. Successful outcomes from this project will help OMTEC to maintain its position as a leader in the development of cutting edge technology for the oil processing of diesel engine application. In addition to technology advancement, the proposed research project will provide opportunities for students to develop strong analytical skills to devise novel power electronic circuits, and to gain extensive hardware testing experience in proof-of-concept power circuit prototypes for microwave energy generation. The developed hardware prototypes of all the devised power conversion circuit concepts will be tested at the Advanced Power Electronics Laboratory for Sustainable Energy Research at York University.

柴油发动机的碳排放是汽车污染的主要来源，对环境有害。 众所周知，柴油机燃烧废气会释放碳黑颗粒，该碳黑颗粒部分地混合在运行和使用过的发动机油中。 根据《巴黎协定》，加拿大承诺到 2030 年将其温室气体排放量 (GHG) 比 2005 年水平减少 30%。为了通过减少碳足迹来应对气候变化，拟议研究项目的目标是调查和开发清洁能源、高功率效率且环保的微波技术，用于处理汽车应用中运行和使用过的发动机油中的碳烟。 特别是，该项目将开发一种新型高功率密度功率转换电路，能够有效地产生微波能量（数千兆赫兹范围内），用于消除碳烟。 在微波能量发生器中，关键元件是高压电源。 因此，需要具有非常高的电压转换比的功率转换电路。 所提出的功率转换电路将具有非常大的升压电压转换比和无损耗开关行为，以最大限度地提高电路效率。 该项目的成功成果将帮助 OMTEC 保持其在柴油发动机应用油加工尖端技术开发领域的领导者地位。 除了技术进步之外，拟议的研究项目还将为学生提供机会，培养强大的分析技能，以设计新颖的电力电子电路，并在微波能量产生的概念验证电源电路原型方面获得丰富的硬件测试经验。 所有设计的电源转换电路概念的开发硬件原型将在约克大学可持续能源研究高级电力电子实验室进行测试。
