Tank sloshing is a serious problem for fuel efficiency. Watch how much air is introduced into the fuel tank in our demonstration video.
Air & Vapor in Diesel Fuel
Retard Injection Timing
Air & vapor are compressible. When air bubbles and/or vapor are present in the fuel, the injection is delayed until the air/vapor is compressed to the injection pressure. The delayed injection results in retarded injection timing, which causes increased fuel consumption, lower power output, and increased exhaust emissions.
After the AirDog® Installation
This picture of the spray pattern taken after the installation of the AirDog® shows definitively the timely injection and full spray pattern when all air and vapor have been removed from the fuel. The diesel engine now, with correct injection timing restored, will be able to deliver the fuel economy, and the power output the engine designers intended.
Before AirDog® Installation
This spray pattern picture was taken before the installation of the AirDog®. The delay of pressure buildup caused by the presence of air effects the timeliness of the injection. This injection is delayed and will result in a late ignition, loss of power and a lot of unburned fuel exiting the exhaust in the form of black smoke. Additionally, it will take more fuel to create a greater combustion for the engine to produce acceptable power output.
