Propane enrichment for diesels 5

[sportster]

I recently read about an after-market kit for electronic injection turbo-diesel automobiles which injected propane into the intake manifold. This proportedly improved emmissions (gaseous and particulate), power, torque, and fuel-economy. The system ran on a maximum 15% propane (15% of caloric imput I presume). Economy must have been computed as % ultimate efficencey of the combined fuels(?). The kit seemed to rely on the electronic diesel-fuel management system to lean out the charge to achieve appropriate exhaust O2 levels. Unfortunately, I've forgotten the name of the company and have had no success searching the internet...

I am interested in finding independant studies or documentation of this type of "dual-fuel" system and verifying its benefits. Does anyone know of application of this system?

For what its worth, I added a section to the FAQ at the top of this column, on dual fuel with LPG.
