Abstract
A U.S. Department of Energy-supported research project which encompassed the testing of 19 different configurations of a modified 1.6-liter displacement automotive engine has yielded a hydrogen-fueled automobile engine design data base. Design data extends to engine performance and exhaust emission levels over a maximum load range and at a fixed speed of 1800 rpm, with high efficiency spark advance. Although load range was occasionally limited by intake manifold backfiring and lean limit restrictions, effective measures have been developed for the obviation of these problems, demonstrating high engine efficiency and specific power with low emission levels.
