抄録

The ignition enhancement effects of hydrogen addition to lean ethanol vapor-air mixtures are experimentally investigated. Hydrogen addition decreases the lean limit of equivalence ratio from 0.80 down to 0.36. The peak overpressure increases and ignition delay time decreases under the conditions of equivalence ratio below 0.80. Hydrogen addition effect is also confirmed using detailed computations of reaction mechanism. Chain reactions including H 2 are primary ignition enhancing mechanism.
