This effort explores the feasibility of extending the dilution limit of an engine during cold-start conditions by using reformer gas and characterizes experimentally the chemical interactions of reformer gas with large-carbon-number hydrocarbon fuels representative of gasoline over a range of pressures, temperatures, and equivalence ratios. The investigation includes determination of flame speed with digital particle-imaging velocitmetry (DPIV) using a counterflow burner, and characterization of oxidation scattering, and planar laser-induced fluorescence (PLIF) using a piston reactor. Engine experiments are conducted to determine the effect from the use of reformer gas on cold-start hydrocarbon emissions.Under the education plan, research findings are integrated into course development. The program also includes outreach efforts at the precollege level including science project advising, classroom visits, hands on laboratory sessions, and laboratory demonstrations.

这项工作探讨了通过使用改革剂气体在冷启动条件下扩大发动机稀释极限的可行性，并通过实验表征改革者气体与大碳量的碳氢化合物燃料的化学相互作用，代表汽油的大型压力，温度和等效率。 研究包括使用逆流燃烧器和氧化散射的表征以及使用活塞反应器的平面激光诱导的荧光（PLIF）来确定使用数字粒子成像速度（DPIV）的火焰速度。 进行了发动机实验，以确定使用改革剂气体对冷启动碳氢化合物排放的影响。在教育计划下，研究结果纳入了课程开发中。 该计划还包括在预科水平上进行的宣传工作，包括科学项目咨询，课堂访问，实验室会议和实验室示范。
