ABSTRACT:
A valve for the intermittent introduction of fuel, in particular gaseous fuel, into an intake tube of an internal combustion engine, which is provided with an electrically actuatable valve member disposed in a valve housing. The valve comprises a slide valve having a substantially cosine-like metering motion, and a metering conduit that opens only after a predetermined portion of the metering motion beyond a position of repose of the valve member is provided. As a result, the control edges are overtaken very fast, and a steep rise or drop in the insufflated fuel quantity takes place. A good approximation to the ideal course, which is equivalent to the course of the aspirated air quantity, is therefore achieved.
