Built-In Exhaust Gas Maintenance Device

A built-in exhaust gas management device characterized in that it comprises:

• a first baffle (1) with coupling means (16) configured for surrounding the outlet of a particulate filter or a catalytic converter,
• a second baffle (2) spaced from the first baffle (1),
• a first perimetral casing (7) extending between the first baffle (1) and the second baffle (2) such that it defines a first chamber (3) intended for housing a coolant fluid,
• a second casing (5) arranged covering at least part of the surface of the second baffle (2) opposite the surface oriented towards the first chamber (3) such that a second chamber (8) for collecting cooled exhaust gases is defined,
• one or more cooling pipes (4) housed inside the first chamber (3) where each pipe (4) is attached at one end to the first baffle (1) and at the second end to the second baffle (2) such that it communicates the outlet of the particle filter or catalytic converter with the second chamber (8) for the passage and cooling of the exhaust gases passing therethrough,
• an inlet (11) and an outlet (12) of the first chamber (3) for the passage of coolant fluid through the first chamber (3),
• the first baffle (1) shows a first area in which the cooling pipes (4) are distributed and a second area free of cooling pipes (4);
• and,
• a segment of exhaust pipe (9) attached to the first baffle (1) through the second area free of pipes (4) in communication with the outlet of the particulate filter or catalytic converter for the exit of exhaust gases,
• where the second chamber (8) has a cooled gas outlet intended for reaching the engine intake.
