Abstract:
A fuel injection system for reducing emissions generated by combusting a fuel, said fuel injection system comprising a fuel injector and a catalyst unit for reducing emissions generated by combusting a fuel, said catalyst unit comprising a support having therethrough a plurality of through-holes formed by sidewalls of the support and a catalytically-effective amount of a catalyst on a portion of said sidewalls such that at least one catalyst-coated through-hole is adjacent at least one through-hole having no catalyst coating, said catalyst unit having a size suitable for placement in a reciprocating engine, wherein said catalyst unitis positioned downstream of the fuel injector a distance such that the catalyst unit receives a liquid fuel droplet and vaporizes the liquid fuel droplet at operating conditions, and is attached to the fuel injector.
