Petrol engines, diesel engines, plug-in hybrids, battery or hydrogen fuel cells seem confusing but necessary varieties as powertrains in the near or long term future. Enhanced efficiency through more advanced technology is needed consistently across all model series. Petrol internal combustion (IC) engine has experienced a remarkable development in the past years, through the engine downsizing, variable valve timing, direct injection, turbocharging and internal friction reduction, etc. However, to fully utilize the advanced combustion technology, it would be beneficial if the pistons and combustion chamber walls have a ceramic coating surface (as a protection armour) better against compression loads and heat on one hand; on the other hand, the ceramic coating would reduce combustion heat loss to coolant, leading to high thermal efficiency and thus lower fuel consumption and emission; additionally, the ceramic coating with a proper coating thickness can decrease the heating-up effect to intake air which would reduce tendency of the engine knocking problem. The objective of this proposed research project is to develop smart ceramic oxide coatings on IC engine combustion chamber walls which have appropriate thermal management properties tailored for enhancement of both engine thermal efficiency and power performance. It is expected that the smart coating technology would result in 5-10% improvement in fuel economy and thus reduction of 1 million tons of CO2 emission in Canada if 20% Canadian vehicles use the technology.**The project will hire 1 PDF, 1 Ph.D., 1.5 Master's, 1 Research Associate, and a few Co-op students for their HQP training in university and industrial R&D environments and provide talents for automotive and manufacturing sectors. The outcome of this research would allow automakers to adopt environmentally responsible solutions to reach their emissions and fuel efficiency targets. Thus, the proposed project will be very significant in environmental protection, technological advancement, and job creation and retaining for Canada. ********

汽油发动机，柴油发动机，插电式混合动力车，电池或氢燃料电池似乎令人困惑，但作为动力总成在近期或长期的未来中。在所有模型系列中，都需要通过更先进的技术提高效率。汽油内燃烧（IC）发动机在过去几年中经历了巨大的发展，通过引擎缩小，可变的阀门，直接注入，涡轮增压和内部摩擦减少等。但是，要完全利用先进的燃烧技术，如果活塞壁和耐加热室的加热效果更好，则可以使用高级燃烧技术，并且会有更好的压缩效果。另一方面，陶瓷涂层将减少对冷却液的燃烧热量损失，从而导致较高的热效率，从而降低燃油消耗和排放。此外，具有适当涂层厚度的陶瓷涂层可以降低加热效果，从而减少发动机敲击问题的趋势。该提出的研究项目的目的是在IC发动机燃烧室墙壁上开发智能陶瓷氧化物涂料，该腔室墙壁具有适当的热管理特性，以提高发动机的热效率和功率性能。预计，如果20％的加拿大车使用该技术，则智能涂料技术将导致燃油经济性提高5-10％，从而减少100万吨CO2在加拿大的排放。这项研究的结果将使汽车制造商能够采用对环境负责的解决方案来达到其排放和燃油效率目标。因此，拟议的项目将在环境保护，技术进步以及创造就业机会和保留加拿大方面非常重要。 ********
