A cover for an internal combustion engine assembly that includes a pressurized fuel accumulator feeding fuel to at least one injector is provided, the cover defining, with a cylinder head, a volume designed to receive the common rail and the injector. The cover borders a first sub-volume, designed to receive the injector, and a second sub-volume separated from the first sub-volume by a separation wall of the cover and designed to receive the common rail. The cover includes a frame to be fitted on the cylinder head and a cap removably fitted on the frame. The separation wall is designed for the passage of a fuel connection connecting the injector to the common rail.

1. Cover for an internal combustion engine assembly comprising a pressurized fuel accumulator feeding fuel to at least one injector, the cover defining, with a cylinder head, a volume designed to receive the pressurized fuel accumulator and the injector, the cover bordering a first sub-volume, designed to receive the injector, and a second sub-volume separated from the first sub-volume by a separation wall of the cover and designed to receive the pressurized fuel accumulator, wherein the cover includes a frame to be fitted on the cylinder head and a cap removably fitted on the frame, and wherein the separation wall is designed for the passage of a fuel connection connecting the injector to the pressurized fuel accumulator,wherein the frame defines a first contour of the frame bordering the first sub-volume and a second contour of the frame bordering the second sub-volume,wherein the cap includes walls defining a first contour of the cap coinciding with the first contour of the frame and a second contour of the cap coinciding with the second contour of the frame, andwherein, when the cap is assembled to the frame, the first contour of the cap and the first contour of the frame match to define the first sub-volume and the second contour of the cap and the second contour of the frame match to define the second sub-volume. 2. Cover according to claim 1, wherein the separation wall comprises an aperture for the passage of the fuel connection from the first sub-volume to the second sub-volume. 3. Cover according to claim 2, wherein the aperture is entirely formed in a portion of the separation wall pertaining to the frame. 4. Cover according to claim 2, wherein the aperture is formed at an interface between the frame and the cap. 5. Cover according to claim 1, wherein a height of at least one beam defining the first contour of the frame is higher than a height of at least one beam defining the second contour of the frame. 6. Cover according to claim 1, wherein the cap includes a service trap-door opening into the second sub-volume. 7. Cover according to claim 1, wherein the cap includes an integral cover wall. 8. Cover according to claim 1, wherein the cap includes a removable cover wall. 9. Internal combustion engine assembly, wherein the engine assembly includes a pressurized fuel accumulator feeding fuel to at least one injector, a cylinder head and a cover according to claim 1. 10. Internal combustion engine assembly comprising a pressurized fuel accumulator feeding fuel to at least one injector, a cylinder head and a cover, the cover defining, with the cylinder head, a volume enclosing the pressurized fuel accumulator and the injector, and the cover bordering a first sub-volume enclosing the injector, and a second sub-volume separated from the first sub-volume by a separation wall of the cover and enclosing the pressurized fuel accumulator, wherein the cover includes a frame fitted on the cylinder head and a cap removably fitted on the frame, wherein a fuel connection connecting the injector to the pressurized fuel accumulator passes through the separation wall, wherein the separation wall is extended by an encapsulating element designed to be arranged around the fuel connection in a configuration where the encapsulating element defines an empty volume around the fuel connection, the empty volume extending the second volume up to a connection zone between a connection port of the injector and the fuel connection. 11. Internal combustion engine assembly according to claim 10, wherein a sealing element is located between the cylinder head and the frame. 12. Internal combustion engine assembly according to claim 10, wherein the encapsulating element has the shape of a cylinder having an extremity attached to the connecting port of the injector. 13. Internal combustion engine assembly according to claim 10, wherein a fuel sensor is located in the second sub-volume. 14. Internal combustion engine assembly according to claim 10, wherein the fuel connection includes a pipe having a first portion connected to a connection port of the injector and a terminal portion globally perpendicular to the first portion and connected to the pressurized fuel accumulator. 15. Automotive vehicle, wherein the vehicle includes an internal combustion engine assembly according to claim 10.
