The control of exhaust emissions are facing a moving target that gets ever more stringent once an existing regulation standard is about to be met. The primary regulated pollutants for automotive engines are the nitrogen oxides (NOx), particulate matters (PM), total hydrocarbons (THC), and carbon monoxide (CO). The regulations on fuel efficiency and CO2 emission are in the Euro VI and US5 emission regulations in concert with low carbon vehicles research. To meet the growing global demand for liquid transportation fuels with lower-carbon footage, more efficient, and cleaner-burning engines, methyl ether, i.e., dimethyl ether (DME) and oxymethylene ether (OME) have become an optimal replacement for diesel fuel as the fuel production from bio-sources are gaining better yield. The research project focuses on the systematic investigation and assessment of the feasibility of methyl ethers as alternative fuels in diesel engines using Ford truck engine models. DME and OME are soot-free burning fuels. The DME engines have compatible engine performance in diesel application despite of lower energy density and similar fueling and injection system to liquefied propane gas (LPG) engines, thus relatively cost-effective in after-treatment and fuel management. In parallel with the Ford Europe project which focuses on DME passenger cars, Ford Canada is taking the lead on bringing the fuel suppliers, engine expertise and supply chains to develop DME/OME pick-up trucks, and to demonstrate the DME engine production ability for on-road testing in Canada. The proposed research will include DME/OME fuel impacts on clean combustion control and emission characteristics from fueling management, boost, injection, spray, ignition, and air management to combustion behavior and pollutant formation history. The proposed industry-academic collaborations will address the challenges in developing the DME/OME engine technologies. The targeted engine will be used on the demonstration vehicles after 2-3 years. The outcomes after 5 years will be Ford demonstration DME vehicles on the road tests.

排气排放的控制面临着一个移动的目标，一旦实现了现有的监管标准，它就会变得越来越严格。汽车发动机的主要调节污染物是氮氧化物（NOX），颗粒物（PM），总碳氢化合物（THC）和一氧化碳（CO）。燃油效率和二氧化碳排放的法规与低碳车辆的研究一起在欧洲VI和US5排放法规中。为了满足以低碳镜头，更高效和清洁燃烧的发动机（即甲基醚，即二甲基醚（DME）和氧甲基乙醚（OME）（OME）的增长，以满足全球对液体运输燃料的需求不断增长。生物源的燃料产量正在提高产量。该研究项目的重点是使用福特卡车发动机模型的柴油发动机的甲基醚作为替代燃料的可行性进行系统的研究和评估。 DME和OME是无烟灰的燃烧燃料。 DME发动机在柴油机应用中具有兼容的发动机性能，尽管能量密度较低，并且与液化丙烷气体（LPG）发动机相似的加油和注入系统，因此在后处理和燃料管理方面相对具有成本效益。与福特欧洲项目的重点关注DME乘用车，福特加拿大正在领导着燃料供应商，发动机专业知识和供应链以开发DME/OME Pick-Up卡车，并展示DME发动机生产能力的能力加拿大的公路测试。拟议的研究将包括DME/OME燃料对清洁燃烧控制和排放特性的影响，从燃料管理，增强，注射，喷雾，点火和空气管理到燃烧行为和污染物形成历史。 拟议的行业学术合作将解决开发DME/OME发动机技术的挑战。 2 - 3年后，目标发动机将用于示范车辆。 5年后的结果将是福特示威DME车辆在道路测试中。
