Abstract: A method for manufacturing an ammonia storage cartridge includes a step for supplying a material by ammonia absorption or adsorption by absorbent salts, a step for producing an intermediate element, including compacting the material to form the intermediate element, a step for stacking at least two intermediate elements in a shell of the cartridge, and a step for compressing the stack of intermediate elements in the shell.

Abstract: An exhaust volume for combustion gases from a motor vehicle engine comprises at least one exhaust duct delimited by a wall comprising an end segment, and at least one flange having a bearing surface. The flange delimits at least one exhaust gas inlet communicating with the exhaust duct. The exhaust gas inlet is delimited by a cannon connected to the flange, with the cannon being attached to the end segment. At least one outer neck is attached to the end segment. The end segment is arranged between the flange and the outer neck, with the end segment being pierced with at least one hole between the flange and the outer neck. The end segment, the flange, and the outer neck are being secured through the addition of a filler.

Abstract: The invention concerns a method for making a coated part comprising an injected plastic material structure (4) coated with a main coat (6) and a secondary coat (14) enclosed by the surface of the first coating, comprising the following steps: bonding a secondary blank (30) on the apparent surface of a main blank (22); placing the main blank/secondary blank assembly in a mould (52) of a clamping frame (64) which maintains a clamping edge (24) of the main blank (22); simultaneously shaping the two blanks when the mould is closed; overmoulding the main blank/secondary blank assembly on the side of the main blank opposite the secondary blank with plastic material. The invention is applicable to inside panels of motor vehicle doors.
