Abstract

Catalyst structure, engine, and fuel injection system are disclosed, in which a catalyst structure is positioned between a fuel injector and a combustion chamber in which most or all combustion occurs. The catalyst structure typically promotes some combustion of the fuel, reforming of fuel to generate hydrogen and other reduced species of fuel molecules, or both. The catalyst structure may instead or additionally promote evaporation of fuel droplets. Benefits include reduced emissions of pollutants.
