The AirDog® eliminates the air in the fuel that robs your engine
of consistently greater performance and can also cause permanent damage to your injectors. The AirDog® also
provides the fuel pressures and flows your diesel engine needs to produce maximum power, any time, every time! For serious
performance seekers, whether you run a Cummins Turbo Diesel, Duramax, or Powerstroke on the daily grind or for weekend pleasure,
the AirDog® has something to offer you!
The physics behind AirDog® technology
Diesel fuel contains varying degrees of entrained air in the form of foam on the surface or
suspended in the bulk fluid as tiny bubbles. Additionally, fuel is driven into the fuel pump by atmospheric pressure, which
is usually only enough pressure flow to fill the pump at idle speeds. Consequently, at higher operating RPM’s, the stock
pump cavitates producing vapor. Air and vapor are compressible. The presence of air/vapor
in the fuel injector delays the pressure build-up. | This
delays the injection, resulting in Retarded Injection Timing. Retarded injection timing in
a diesel, just like bad spark plugs in a gasoline engine, causes lost power, poor fuel mileage, and an increase in exhaust
emissions. Retarded Injection Timing caused by air/vapor is the primary source of the rough idle, lost power, increased fuel
consumption and excessive exhaust emissions of the diesel engine. | Air/vapor
in the injector can also cause permanent damage in the form of galling and pitting of the barrel/plunger assembly and tip
erosion. The conventional vacuum feed fuel supply system does nothing to remove entrained
air from the fuel. In fact, it only makes things worse. As the filter plugs with use, the already inadequate fuel flow to
the engine is further reduced, increasing cavitation and retarding injection timing even more. |
