Förfarande och anordning för tillförsel av bränsleånga till en förbränningsmotor

摘要

The invention is directed to a method for controlling the output of fuel vapor from a tank-venting system via a line system to intake channels of individual cylinders of a multi-cylinder engine. The line system branches to respective ones of the cylinders and has at least one controllable valve. The controllable valve alternately releases and blocks the output. The valve is so controlled that the output takes place in synchronism with the periodic repetition of the work cycles of the engine.
