Canada's target is to reduce greenhouse gas (GHG) emissions by 40~45% below 2005 levels by 2030 and to net-zero GHG emissions by 2050. To meet US 2026 and EU 7 emission regulations also, this collaborative research project is to maximize energy efficiency towards low-carbon propulsion with ultra-low pollutant emissions, which require further decrease in both GHG and air pollutant emissions. The proposed research will help Ford and policy makers to lower the transition barrier of decarbonization of engines. Intelligent ignition control strategies will be developed, together with innovative injection strategy and combustion schemes, to realize clean and highly efficient combustion process under both steady-state and transient operation conditions. The proposed research include four main objectives: 1) To improve engine efficiency with ultra low tailpipe emissions via advanced propulsion technologies, including in-cylinder combustion strategy and advanced after-treatment systems.2) To perform a fundamental study on ignition mechanisms of low temperature plasma and on-demand ignition energy scheduling in ultra lean/diluted mixtures; explore the efficacy of advanced ignition strategies under various injection strategies and in-cylinder flow control.3) To study low temperature flame detection mechanisms for prompt and smart combustion diagnostics.4) To develop an intelligent ignition control algorithm in ECU for enhancing the efficacy and durability of the ignition system, enabling clean and efficient combustion with in-cycle closed loop control.With the adaptation of renewable fuels to lower carbon footprint, 40% GHG emission reduction goal is feasible for 2030 target. Benefits expected to engineering disciplines include: a) Development of fuel efficient and clean automotive engines for vehicle downsizing and powertrain hybridization; b) Advanced knowledge of ignition mechanisms for intelligent ignition strategies of adapting various fuels, c)Applicable diagnostic tools to detect and estimate the burning status under excessive lean/diluted conditions for high efficiency.

加拿大的目标是将温室气（GHG）的排放量减少40至45％以下，到2030年，到2050年，到2050年的净零温室气体排放量。要满足我们2026年和EU 7排放法规，该协作研究项目是为了使能源效率最大化，以高低污染物的污染物降低了污染物，这两种污染物均可降低ghg的污染物，并需要降低ghg的空气。拟议的研究将帮助福特和政策制定者降低发动机脱碳的过渡障碍。将制定智能点火控制策略，以及创新的注入策略和燃烧方案，以在稳态和瞬态操作条件下实现干净且高效的燃烧过程。拟议的研究包括四个主要目标：1）通过先进的推进技术，包括超低尾管排放，包括缸内燃烧策略和先进的后处理系统。2）对低温等离子体的点火机制进行基础研究，以进行低温等离子体的点火机制，并在Ultra Lean稀释的混合/稀释的混合物中进行点火机制；探索各种注射策略和缸内流动控制下高级点火策略的功效。为了降低碳足迹，2030目标可行的40％温室气体排放目标是可行的。工程学科预期的好处包括：a）开发用于车辆缩小和动力总成杂交的燃油效率清洁的汽车发动机； b）针对适应各种燃料的智能点火策略的点火机制的高级知识，c）适用的诊断工具，可在过度的精益/稀释条件下检测和估算高效率的燃烧状态。
