本文研究了汽油-乙醇混合燃料（E22）、含水乙醇（E100）和车载制氢的汽车燃油消耗和污染物排放。该研究旨在找出氢是否有助于减少燃料消耗和排放。氢气由适合车辆的水解电池产生，并在进气管中与空气混合。在测试中使用了由1.0 L灵活燃料发动机驱动的生产汽车。在底盘测功机上对车辆进行了测试，发动机在怠速和1400转/分下运行。结果表明，少量的氢气可以提供稳定的发动机运行与稀薄的燃料-空气混合物，从而降低燃料消耗，而不影响废气排放水平。E22和E100的油耗分别降低了11.8%和13.1%。
This paper investigates fuel consumption and pollutant emissions from a vehicle operating with gasoline-ethanol blend (E22), hydrous ethanol (E100) and hydrogen produced on-board. The study aims to find out if hydrogen can contribute to reduce fuel consumption and emissions. Hydrogen was produced by a hydrolytic cell adapted to the vehicle, and was mixed to the air charge in the intake pipe. A production automobile powered by a 1.0-L flexible fuel engine was used in the tests. The vehicle was tested on a chassis dynamometer, with the engine operating at idle speed and at 1400 rev/min. The results show that small amounts of hydrogen can provide stable engine operation with lean fuel-air mixture and, thus, reduce fuel consumption without compromising exhaust emission levels. Reductions of up to 11.8% and 13.1% on fuel consumption were obtained for E22 and E100, respectively.
