How Does the GFD Dual-Fuel System™ Work?
(Standard & Customized Systems Available)

ELECTRONIC & MECHANICAL SYSTEM COMPONENTS KEY

1. System Controller
   Provides for multiple redundancies to prevent damage to an engine utilizing a fumigation system
   
   Adjusts the dual-fuel ratio and fine-tunes the mixture for optimum engine operation.
   
   
2. Wide Band Oxygen Sensor
   Allows for more accurate oxygen sensing and therefore, has the ability to establish and maintain an oxygen level within an exhaust stream
   
   
3. Valve: Electronic Valve
   
   
4. Valve: Electronic Lock-off Valve
   
   
5. Valve: Mechanical Boost Pressure Valve
   
   
6. Gaseous Fuel Delivery Injector
   The GFD (a.k.a. GFI) is coupled to an air intake stream in order to directly inject fuel
