AirDog® II-4G

 

The next generation in the fuel delivery system.

The patented AirDog® II-4G has been quality engineered to remove entrained air and water vapor from diesel fuel. The result is a compact, long lasting, efficient, and quiet fuel system made with superior quality.

Advancing the AirDog® Tradition with the 4th Generation Fuel System!

The AirDog® II-4G system improves engine performance by:

Maintaining Correct Injection Timing

Eliminating Spray Pattern Disruption

Allowing for a Full Power Stroke and Complete Burn

Benefits of the AirDog® II-4G:

Increased Fuel Economy

Increased Power Output

Increased Torque Output

Longer Injector Life

Improved Throttle Response

Reduced Exhaust Emissions

Optimized Engine Performance

AirDog® II-4G also overcomes loss of power for diesel engines operating at higher altitudes.

AirDog® II-4G Fuel Air Separation System featuring Demand Flow Technology and Enhanced Features

AirDog® II-4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gear rotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining enters the fuel pump.

The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog® II-4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.

The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.
