Abstract
A fuel saving device is described that comprises a mixer, a control, and a bypass air tap through a connection hose between the hose leading from the air filter to the crankcase and the hose leading from the air filter to the control. The mixer possesses a mixing orifice in the form of a hollow rod, that is formed as a triangular section provided with slits. An important feature is the tap of the bypass air out of the hose to the crankcase. With this tap particularly efficacious mixing proportions are obtained in the mixer with respect to a favorable preparation of the fuel-air-mixture.
