EPSRC : Alex Gander : EP/S513751/1Improving air quality while supporting clean growth and future transportation technology represents a significant societal challenge for Canada and the UK. Emissions of unburnt hydrocarbon (uHC) fuel directly affects public health, and their reduction from vehicles such as hybrid cars require new solutions. Recent research conducted by Professor Cyril Crua's team at the University of Brighton has demonstrated that large fuel films on the tip of injector nozzles can be stripped and released in the form of unburnt fuel. However it is not currently possible to establish how much of this liquid fuel is actually released into the exhaust in the form of uHCs. This project will establish a new collaboration with the team led by Prof. Patrick Kirchen at the University of British Columbia to develop a novel high-precision laser-based sensor that can unveil the link between the formation of fuel films inside engines, and the release of unburnt fuel into the exhaust. This will enable both teams to significantly accelerate our understanding of the mechanisms that lead to the release of uHCs into the environment, and their impact on air quality.

EPSRC：Alex Gander：EP/S513751/1改善空气质量的同时支持清洁增长和未来的交通技术对加拿大和英国来说是一个重大的社会挑战。未燃烧碳氢化合物(UHC)燃料的排放直接影响公众健康，而混合动力汽车等车辆的减排需要新的解决方案。布莱顿大学西里尔·克鲁亚教授的团队最近进行的研究表明，喷油器喷嘴尖端的大燃料膜可以被剥离并以未燃烧燃料的形式释放。然而，目前还不可能确定这种液体燃料中有多少实际上是以超HCS的形式排放到废气中的。该项目将与不列颠哥伦比亚大学的Patrick Kirchen教授领导的团队建立新的合作关系，开发一种新型的高精度激光传感器，该传感器可以揭示发动机内部燃料膜的形成和未燃烧燃料释放到尾气中之间的联系。这将使两个团队能够显著加快我们对导致UHCS释放到环境中的机制及其对空气质量的影响的理解。
