About DFS

By injecting gas: soot, smoke and
fuel dust(particles) are decreaseing.

The DFS system is operated by injecting pulverized LPG or CNG (measured gas) into the carburetor choke through a calibrated hole, the nozzle. Thus the vehicle runs by duel fuel simultaneously, engine operation is more efficient, performance and moment higher, diesel consumption and costs are lower.The dual system does not modify the engine or other emission systems.

The vehicle starts in diesel running. If the switch is in duel running the gas ECU (central unit) checks the needed conditions for starting the injection.
