Fuel injection device for internal combustion engine has damping elements of metal foam accommodated at respective connecting points between injector and cylinder head and between fuel rail and injector

摘要

The fuel injection device for an internal combustion engine has at least one injector (2) to inject fuel directly into the combustion chamber, and a fuel rail (3) to press the injector at a connecting point (13) against the cylinder head (1). A damping element (14) of metal foam is accommodated at the connecting point between the injector and cylinder head, and an additional damping element (19) of metal foam is accommodated at a second connecting point (18) between the fuel rail and the injector.
