I was handed a brochure yesterday at the local Diesel parts store. The topic was a propane aspiration system for diesels. Now as I understand the normal alternative fuel system a diesel will run off either diesel fuel, propane, or CNG, but not at the same time. This system (Bully Dog Tech) injected the propane in through the air intakes while still using diesel. The system works with the computer to determine the amount of porpane to be injected (like NO2). It can also been swithced on or off and supposedly is for continous driving. I was wondering if anyone out there has any expierence with this or can give me a good reason to choose one system over the other.
