A liquid injector 1 has an injector body 3 provided with an injection passage 7 which is formed by the cavity between the inner wall 9 of the injector body and a needle 5 and the cavity in a hole 13 located in the wall 11 of the injector body. The liquid injector 1 further has a spherical, hollow porous element 15 which extends beyond the injector body 3 and is formed by a semi-sphere which is fixed to the injector body and closes off the injection passage 7. The wall thickness of the porous element 15 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 19 has the shape of a semi-ellipse.
