Mixer
The gas is mixed with the intake air
tangentially. This makes mixing very
efficient. The gas content is controlled with
a flap mounted in the air pipe before the
mixing unit. This flap need not to be
completely air tight. The power of the ICE
is controlled with a flap mounted in the
intake pipe after the mixing unit. This flap
must be exactly correctly shaped,
otherwise the idling speed can not be
adjusted. The later flap is equipped with a
screw for idling speed adjustment. The
flaps must be supported gas tight. Suitable
material for the bearing bushes is for
example nylon which produces a
maintenance-free construction. The flaps
are controlled with levers mounted on a
suitable location.Translated by Olli.
