- the fixing support of the invention comprises means for tilting said post-processing system so that a longitudinal axis of said post-processing system forms a non-zero angle with respect to a median plane. longitudinal of said engine block, which allows to allow the attachment of said engine block to the frame through this support.
- the invention thus creates a mounting area to the chassis to move from a transverse engine installation to a longitudinal installation without modifying the engine block or the post-processing system.
- said support comprises: first fixing means to said engine block,
- said first and second fixing means to said engine block and said post-processing system have a first or second axis oriented in a direction perpendicular to said longitudinal median plane of said engine block.
- said third chassis attachment means has a third axis oriented in a direction parallel to said longitudinal median plane of said engine block.
- said first, second, and third fastening means each comprise at least one opening for receiving a corresponding fastening element.
- said post-processing system comprises tabs provided with holes each intended to come opposite a corresponding opening of the second fastening means of said support.
- said fixing bracket is fixed in an area located in a lower part of said engine block on the exhaust side. This area located in the lower part of the engine block has a high rigidity on the engine block.
- said angle of inclination between said longitudinal axis of said post-processing system and said longitudinal median plane of said engine block depends on a space required for an implantation of the third fastening means to said frame.

- the invention also relates to a motor vehicle which comprises an internal combustion engine as defined above or an assembly as defined above.
- a motor vehicle which comprises an internal combustion engine as defined above or an assembly as defined above.
- Figures 1a and 1b are perspective views from different angles of an internal combustion engine according to the state of the art installed in a transverse configuration
- Figure 2 shows a perspective view of a mounting bracket according to the present invention supporting a post-processing system installed at the exhaust outlet;
- Figure 3 is a perspective view of a mounting bracket attached to the engine block according to the present invention without the post-processing system;
- Figures 4a and 4b are perspective views from different angles of an internal combustion engine according to the present invention installed in a longitudinal configuration and in particular provided with a post-processing system inclined with the aid of a mounting bracket;
- FIGs 4a and 4b show an internal combustion engine 1 comprising a motor block 2, seat of the combustion of air and fuel.
- the engine block 2 comprises a cylinder block having cylinders defining combustion chambers.
- the cylinder block is closed in its upper part by a cylinder head 6 covered with a cylinder head cover and in its lower part by an oil sump 7 allowing the internal lubrication of the engine block 2.
- the engine block 2 contains a system mobile comprising pistons sliding inside the cylinders in a reciprocating rectilinear motion and a crankshaft connected to the pistons by means of connecting rods so that the relative movement of the pistons rotates the crankshaft.
- the engine 1 also comprises a post-processing system 20 installed at the output of the engine block 2 on the exhaust side face.
- This post-treatment system 20 protected in its upper part by a heat shield, allows the depollution of the gases exhaust system from the engine block 2.
- the post-processing system 20 includes a catalyst supplied with catalytic liquid by injectors.
- the post-treatment system may also include a particulate filter and / or a nitrogen oxide treatment system.
- this post-processing system 20 comprises fastening lugs 21 in order to be fastened to the engine block 2 by means of a support 10.
- the support 10 is fixed in a zone 3 of attachment.
- This zone 3, visible in FIG. 3, is preferably located in the lower part of the engine block 2 because it has a high rigidity on the carrier element 2.
- the support 10 is fixed to the zone 3 by means of fixing means 1 1.
- the fastening means 1 1 comprise openings, in this case three in number, in which are inserted fasteners, for example elements of the screw type or stud-nut system. These openings have a first axis Y1 substantially perpendicular to the longitudinal median plane 5 of the engine block 2. It will be noted that these fastening means 1 1 use the same attachment points on the zone 3 as those used by the carrier 1 10 of the state of the art, which allows to fix the supports 10 to the pre-existing engine blocks 2.
- the support 10 comprises fastening means 12.
- These fastening means 12 comprise, for example, openings made in portions 120 projecting from the support 10, such as spacers 120, intended to be positioned opposite holes in the fastening lugs 21 and intended to receive a fastener, such as a screw, a rivet or a stud-nut.
- the openings have a second axis Y2 substantially perpendicular to the longitudinal median plane 5 of the engine block 2.
- the fastening means 12 and the tabs 21, for example two in number, are positioned in a transverse direction of both sides. Another of the post-processing system 20.
- the invention avoids having to modify the shape of the fastening tabs 21, or of the post-processing system 20 with respect to the configuration of the state of the art. in order to reuse the pre-existing post-treatment systems.
- the support 10 and the spacers 120 are configured to tilt the post-processing system 20 so that its longitudinal axis X forms an angle with respect to the longitudinal median plane 5 of the block
- the inclination is defined by a length of the spacers 120 whose end faces may be inclined to cooperate with the fastening lugs 21.
- the outlet 200 of the after-treatment system 20 going to the turbocharger 40 can be adapted according to the angle a.
- the angle of inclination a depends on a space necessary for an implantation of a fastening means 13 to the frame. In an exemplary embodiment, the angle of inclination a is at least equal to five degrees. The distance of the post-processing system 20 from the engine block 2 thus makes it possible to create a zone of attachment to the chassis of the vehicle.
- the support 10 comprises at least one fastening means 13 for establishing a connection between the engine block 2 and the vehicle chassis.
- the fastening means 13 comprises at least one opening having a third axis Y3 substantially parallel to the longitudinal median plane 5 of the engine block 2, or in other words substantially perpendicular to the first and second axes Y1 and Y2 fastening means 1 1 and 12.
- the opening is intended to allow the passage of a fastener, such as a screw or a stud-nut system.
- the fastening means 13 may be connected to a damping foot of the chassis of the vehicle.
- this support 10 allows a motor 1 initially intended to be installed transversely to be installed longitudinally with respect to the longitudinal axis of the vehicle while maintaining the same post-processing system 20 and the same. engine block 2.
- the invention has been described in the context of an internal combustion engine installed in a vehicle engine compartment.
- the invention finds a particularly advantageous, but not exclusive, application for motorized means of maritime or terrestrial locomotion, such as motor vehicles.
- the invention may also be used with an alternator to ensure its drive or with a hydraulic pump, or in any other industrial application requiring the integration of an internal combustion engine in a longitudinal configuration.
