An insulating element for a fuel injection apparatus is notable in particular for the fact that a low-noise design is achieved. The fuel injection apparatus encompasses at least one fuel injection valve and one receiving bore in a cylinder head for the fuel injection valve, and the insulating element between a valve housing of the fuel injection valve and a wall of the receiving bore. The insulating element possesses an inner insulating ring that is present in encapsulated fashion between an outer ring and an inner ring. The outer ring is directed toward the fuel injection valve and the inner ring is directed toward the wall of the receiving bore, so that corresponding abutment of these components occurs with the insulating element in the installed state. The fuel injection apparatus is suitable in particular for direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignited internal combustion engine.
A multi-part insulating element for a fuel injection apparatus for a fuel injection system of an internal combustion engine for direct injection of fuel into a combustion chamber, the fuel injection apparatus comprising:
