A fuel injection device includes at least one fuel injector, one mounting hole in a cylinder head for the fuel injector, and a decoupling element between a valve housing of the fuel injector and the wall of the mounting hole. As a lenticular spring element, the decoupling element has a nonlinear, progressive spring characteristic curve, such that a low rigidity of the decoupling element prevails during idle operation and a high rigidity of the decoupling element prevails during nominal system pressure.
