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。 已知柴油机燃烧废气释放碳烟颗粒，其部分地混合在操作和使用的发动机油中。 根据《巴黎协定》，加拿大承诺到2030年将温室气体排放量在2005年的基础上减少30%。 为减少碳足迹以应对气候变化，拟议研究项目的目标是研究和开发一种清洁、高功率效率和环保的微波技术，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，拟议项目将开发一种新型的高功率密度功率转换电路，能够有效地产生微波能量（在数千MHz的范围内），用于消除碳烟灰。 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，具有无损耗的开关行为，以最大限度地提高电路效率。 该项目的成功成果将有助于OMTEC保持其在柴油发动机应用油加工尖端技术开发方面的领导者地位。 除了技术进步，拟议的研究项目将为学生提供机会，培养强大的分析能力，设计新颖的功率电子电路，并获得广泛的硬件测试经验，在微波能量产生的概念验证功率电路原型。 所有设计的功率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。
