    Product information

    During the startup phase, the auxiliary air device provides additional air so that, together with the additionally supplied fuel, the greater friction of the cold engine can be overcome.

    An aperture in the auxiliary air device controls the amount of air that flows through. It is installed on the engine to absorb its heat. It is also electrically heated to track with the engine characteristic. The hotter the engine, the less additional air is provided.

    The auxiliary air device is therefore a functional component of the fuel injection system.
