Abstract

A magnetic valve (3) is fitted in an injection pipe (4) remotely from an injector. The injector acts as an injection jet (5) The injection pipe between the magnetic valve and the injection jet is so designed that pressure level against the injection jet can momentarily be raised excessively in an injection area above the maxima for pressure swings in fuel pillars in the injection pip in contrast to pressure in a joint common rail (1).
