Fuel e.g. DERV fuel, injection device for internal combustion engine of motor vehicle, has tube for connecting common ramp to injector, and cavity connected to tube, where volume of cavity is adjustable with respect to nominal volume
The device has a tube (1) for connecting a common ramp (2) to an injector, and a cavity (8) filled with fuel and connected to the tube. A channel (6) connects a cylindrical housing (7) to the tube. The channel and cavity form a Helmholtz resonator. The volume of the cavity is adjustable with respect to nominal volume. A pressure regulator (12) is connected to the cavity and activated by a logic controller of an internal combustion engine. An independent claim is also included for a method for injecting a fuel.
