Canada’s commitment to Paris accord can only be realized with a significant reduction in emissions from oil and gas, and transportation sectors. Oil and gas accounts for 26% and transportation for 23% of Canada’s total GHG emissions. In North America, combustion of gasoline and diesel fuel make up for 84% of all transportation energy. Therefore, any improvement in combustion energy efficiency, can have a large impact on the total emission. Combustion efficiency and emission intimately relate to the fuel injection and mixing inside the combustion chamber. More and more engines utilize Gasoline Direct Injection (GDI) because of its higher fuel efficiency. In addition, diesel and biodiesel fuels are become more popular, again because of their fuel efficiency. Therefore, further improvements in the fuel efficiency and emission reduction require a better understanding of the fuel injection and atomization processes and development of models to predict these processes. Such models can be implemented in spray combustion codes to modify engine designs, optimize the combustion efficiency, and reduce emissions.

加拿大对《巴黎协定》的承诺只有在石油、天然气和运输部门大幅减少排放的情况下才能实现。石油和天然气占加拿大温室气体排放总量的26%，交通运输占23%。在北美，汽油和柴油燃料的燃烧占所有运输能源的84%。因此，任何燃烧能源效率的提高，都可以对总排放量产生很大的影响。燃烧效率和排放与燃烧室内的燃油喷射和混合密切相关。越来越多的发动机采用汽油直喷（GDI），因为它具有更高的燃油效率。此外，柴油和生物柴油燃料越来越受欢迎，也是因为它们的燃油效率高。因此，进一步提高燃油效率和减少排放需要更好地了解燃油喷射和雾化过程，并开发模型来预测这些过程。这些模型可以在喷雾燃烧规范中实现，以修改发动机设计，优化燃烧效率，减少排放。
