The invention concerns a device for facilitating the insertion of a piston with the segments thereof into a cylinder of a vehicle internal combustion engine. This novel device has the shape of a cylindrical tube comprising a tubular lower portion intended to guide said tube into the cylinder of the engine and called "portion for guiding into the cylinder" (11), and a tubular upper portion intended to guide and insert the piston with the segments thereof and called "piston insertion portion" (12). The piston insertion portion (12) has a conical inner surface comprising, in the axial direction ("ZZ'") of the tube, first (12A) and second (12B) sloping sections. The two sections (12A, 12B) have different slopes and are separated by a cylindrical connection section (12C) so as to allow tilting from one slope to the other in good conditions when the piston is inserted. Motor vehicles. Assembly of internal combustions engines of motor vehicles. Assembly of pistons with the segments thereof in the cylinder housings of motor vehicles. |
