Abstract
A device for injecting fuel over a cylinder head of an engine, including a tubular body, an injection nozzle forming an extension of the tubular body, a needle extending coaxially to the nozzle in a form of a rod, an end of which includes a head forming a valve on a seat supported by the injection nozzle, and an actuator configured to cause a movement of the head so as to open the valve, the needle configured to axially resonate when the same is subjected to axial pulses at a predetermined nominal frequency by the actuator. A system for mounting the device includes a spacer for bearing on the cylinder head, as well as on a front surface of the tubular body at the connection to the nozzle.
