Abstract
A liquid injector has an injector body provided with an injection passage which is formed by the cavity between the inner wall of the injector body and a needle and the cavity in a hole located in the wall of the injector body. The liquid injector has a spherical, hollow porous element which extends beyond the injector body and is formed by a semi-sphere which is fixed to the injector body and closes off the injection passage. The wall thickness of the porous element is not the same throughout. In the middle the wall is thinner than near the edge, so that during the injection action the fuel vapour has the shape of a semi-ellipse.
