Natural gas use in a diesel engine - methane emission testing

这一关系的目标是能够测量以天然气为主要燃料的压燃式双燃料发动机的甲烷气体排放。发现燃料技术公司的燃料系统产品将用于供应含氧飞行员燃料。为了这一开发的成功，发现号需要进行发动机测试，以确定在柴油发动机的最佳燃料条件下减少甲烷排放的方法。皇后大学和发现号已经在皇后大学发动机实验室现有的测功机上安装了一台柴油发动机和所需的外围传感器。该发动机被用作初始接合项目的一部分，以测量在不同发动机速度和负荷下使用柴油的发动机性能。还对二甲醚进行了一些有限的测试，以验证燃料 系统能够处理更易挥发的燃料。在这个后续的Engage Plus项目中，将进行测试，以确定在使用天然气和压缩可点火柴油和氧气为发动机加油时获得的甲烷排放量。该项目允许Discovery访问女王学院Ciccarelli燃烧小组的高级燃烧技能集，这些技能在工业中找不到。在该计划中获得的数据将使Discovery的产品得到优化和持续的开发，并导致额外的资金和雇用加拿大人。

The objective of this relationship is to allow the measurement of methane gas emissions from a compression ignition dual-fuel engine operating with natural gas as the primary fuel. Discovery Fuel Technologies' fuel system product will be used to supply the oxygenate pilot fuel. For this development to be successful, Discovery requires engine testing to identify methods to reduce methane emissions under optimal fueling conditions of the diesel engine. Queen's University and Discovery have set up a diesel engine and the required peripheral sensors on an existing dynamometer located in the Engine Laboratory at Queen's University. This engine was used as part of an initial Engage project to measure engine performance with diesel fuel at various engine speeds and loads. Some limited testing was also done with dimethyl-ether in order to verify that the fuel system is capable of handling the more volatile fuel. In this follow-up Engage Plus project tests will be performed to identify the amounts of methane emissions obtained when fueling the engine with natural gas and a compression ignitable diesel and oxygenate. The project allows Discovery access to the advanced combustion skill-sets of the Ciccarelli Combustion group at Queen's, skills not found in Industry. Data obtained in this program will allow optimized and continued development of Discovery's product and lead to additional funding and the hiring of Canadians.
