ABSTRACT:
An apparatus for producing a defined fuel vapor-air mixture for engines with an intake manifold. The apparatus including a float chamber and a vaporizing chamber accommodating a heated vaporizer surface. The intake manifold is provided with a first fixed restrictor or nozzle and a liquid space of the float chamber and a liquid space of the vaporizing chamber are connected with each other by a conduit. A gas space of the float chamber, as seen in a flow direction upstream of the first restrictor or nozzle, and a gas space of the vaporizing chamber as seen in a flow direction downstream of the restrictor or nozzle, are respectively connected to the intake manifold by means of conduits. A conduit from the gas space of the vaporizing chamber into the intake manifold is provided with a second fixed restrictor or nozzle causing a pressure drop of about 85%-99.99% of the first restrictor or nozzle. The vaporizer surface is arranged above the liquid level adjusted by the float chamber in such a way that the wetted vaporizer surface increases with a rinsing liquid level.
