Abstract
A decoupling element for a fuel injection device provides a low-noise construction. The fuel injection device has at least one fuel injection valve and a receiving bore in a cylinder head for the fuel injection valve as well as the decoupling element between a valve housing of the fuel injection valve and a wall of the receiving bore. The spring rigidity of the decoupling element is so low and the decoupling element is placed between the valve housing of the fuel injection valve and the wall of the receiving bore in such a way that the decoupling resonance is located in the frequency range below 2.5 kHz. The fuel injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignited internal combustion engine.
