- EGR Exhaust Gas Recirculation
- exhaust gas will be used specifically to designate the gases resulting from the combustion process between the fuel and the feed air in the engine, before any mixing.
- an engine operates with all of its cylinders following a known cycle (Admission - Compression - Combustion / Relaxation - Exhaust).
- This cycle is characterized by its efficiency, which is recognized as optimal when the losses due to the transfer of gases, also known as pump losses, during the intake and exhaust phases are minimal.
- it has already been proposed to deactivate one or more cylinders during operation at low load or, more generally, when the requested power can be provided by only a portion of the engine cylinders.
- the device presented in the aforementioned document poses implementation difficulties.
- the good performance of the engine depends in particular on a proper gas supply of each cylinder.
- the introduction of partitioning in the collector disturbs the distribution of the cylinder feed streams.
- the intake manifold incorporates a heat exchanger to cool the intake gases, in order to increase its density. Given this integration and congestion constraints, the space left free in the collector is then insufficient to practice a partition that feeds the cylinders properly.
- the object of the present invention is to make it possible to implement, on an existing engine, cylinder deactivation by supplying it with exhaust gas in a reliable manner, flexible as regards the control of the cylinders, and without the need to rethink the design. of the admission system.

- the plug contributes to facilitating the flow and minimizing the pressure losses by deflecting the flow of exhaust gas to the cylinder.
- the flow control means is placed substantially at the mouth of the conduit opposite that intended to supply the cylinder. This location generally corresponds to the mouth of the conduit in the manifold and is clear enough to install the device into a power module.
- said device further comprises a controllable shutter means of the exhaust gas inlet capable of sealing said exhaust gas inlet.
- a controllable shutter means of the exhaust gas inlet capable of sealing said exhaust gas inlet.
- the device can be difficult to achieve, for example, a plug which hermetically closes the exhaust gas supply in the engine cylinder feed duct. It may therefore be interesting to complete the device by installing, for example a valve or a flap.
- the seat of the valve is formed by a portion of said duct.
- the device is advantageously completed by adding means for controlling the flow control means in the conduit and control means of the hermetic closing means of the recirculated exhaust gas inlet. They may in particular be able to open said shutter means when said flow control means is in its second position and to close said shutter means when said flow control means passes into its first position.

- Figure 6 shows a variant of Figure 5.
- the invention relates to an intake module intended to be placed on the cylinder head of an engine which comprises for each cylinder a duct 1 or a pair of ducts 1 intended to extend into the cylinder head to supply said cylinder. intake gas cylinder.
- This duct 1 opens upwards in a free volume 2 of the intake manifold 3.
- This manifold 3 has the shape of a box itself fed with inlet gas by a system not shown in the figure.
- the first function of this manifold is to distribute the flow of intake gas between the ducts, such as that shown in Figure 1, dedicated to each cylinder.
- this manifold 3 incorporates a heat exchanger 4 through which the inlet gases pass before arriving in the free volume 2, in communication with the supply ducts of the various cylinders.
- a heat exchanger 4 through which the inlet gases pass before arriving in the free volume 2, in communication with the supply ducts of the various cylinders.
- the invention more particularly relates to a device for controlling the flow of the intake gases and / or recirculated exhaust gas which can be integrated into this module of admission.
- Said flow control means here comprises a rotary valve 5 installed on the conduit 1, at its mouth in the manifold 3, forming a controllable shutter system of said conduit.
- FIG. 1 shows this rotary plug 5 in a first position, leaving completely free the passage in the conduit 1 of the gas flow intake, represented by the arrow, to the cylinder below.
- the inner shape of the duct 1 is here delimited by two substantially plane 6-7 and parallel walls connected at their ends by two curved walls. Under these conditions, the plug 5 is cut into a cylinder of axis R parallel to the two plane walls 6 -7 and transverse to the duct 1.
- This transverse cylinder has a diameter greater than the distance between the two walls 6-7 and is positioned to be tangent to the inner face of the wall 6 of the duct 1 which connects with the bottom of the collector 3.
- the opposite wall 7 is shaped with a boss 8 arranged to form a housing within which the plug 5 in the transverse cylinder can rotate while remaining in contact with the wall in the boss 8.
- This wall 7 is connected to the side wall of the collector 3.
- the plug 5 comprises in particular a transverse part 9, having substantially the same extension along the axis R as the plane walls 6-7, and occupying a portion of an angular sector of the transverse cylinder, as well as two circular cups, connected to the ends of the transverse part 9. Said cups may form the walls of the duct 1 between the flat walls 6-7, at the plug 5. Only one of these cups 10 is shown in FIG. Similarly, the plug 5 advantageously comprises a mechanism adapted to rotate it about the axis R of the transverse cylinder which is not shown in the figure. The cups 10 do not participate in the closing / opening function of the duct 1 but they hold the plug 5 in its housing during its rotations, turning in a portion of the walls of the duct 1 forming an abutment.
- said plug ensures a flow control function, allowing the inlet gas to pass into a first position and blocking it in a second position.
- This operation is described below.
- the plug 5 is in a first position leaving the passage of the inlet gas.
- the angular extension of the transverse part 9 corresponds to the transverse cylinder portion passing through the inner flat face of the wall 7 connected to the side wall of the collector 3.
- the outer face 1 1 of the transverse part 9 of the plug 5 follows the transverse cylinder to be able to rotate at the interior of the housing formed by the boss 8 while remaining in contact with its inner wall.
- the inner surface 12 of the transverse wall 9 of the plug 5, for its part, substantially reproduces the inner flat surface of the wall 7 of the duct 1, in continuity of shape with the surrounding wall 7.
- the plug 5 has been rotated about the axis R of the transverse cylinder so as to be in a second position, where the transverse part 9 blocks the section of the duct 1 in front of the plug 5 with respect to the collector 3
- the transverse cylinder must have a sufficient diameter, larger than the gap between the plane walls 6-7.
- the diameter of the transverse cylinder in which the transverse part 9 is inscribed, as well as the internal shape of the cups 10 are advantageously configured to have a plug of minimal space, which leaves a free passage of the inlet gases in the section of the led 1 when the plug 5 is installed in its first position and which completely closes the section of the duct 1 when the plug 5 is in its second position.
- the shape of the plug is briefly described here in the case of a conduit having two substantially parallel walls. It can of course be used with conduits of different section, for example circular.
- the plug 5 presented here also fulfills the second part of the flow control function for supplying the engine cylinder, allowing the recirculated exhaust gas to arrive when it is in the second position described above, and blocking this passage when in the first position.
- an opening 13 is here made in the boss 8 of the wall 7 where the transverse portion 9 of the plug 5 is housed.
- this wall 7 is arranged around said opening 13, in particular with a fastening flange 14, so that a second duct of section corresponding to that of the opening 13 comes to be connected.
- the end of this duct is oriented substantially perpendicularly to the axis of rotation of the transverse cylinder in which the plug fits 5.
- the size of this opening 13 is smaller than the extension of the boss 8 on the wall 7 of the inlet duct 1 of the engine cylinder.
- the transverse portion 9 obstructs the opening 13 and, in addition, its outer face 1 1 is in contact with the inner wall boss 8 at a determined distance around this opening January 1 3, which improves the seal.
- the section of the opening 1 3 is lower than that of the intake duct 1.
- the conduit which is connected to this opening 13 is fed with exhaust gases recovered at the output of the engine. Therefore, with reference to what has just been explained, when the plug 5 is in its first position, it blocks the introduction of exhaust gas into the conduit leading to the engine cylinder and when it is in its second position. it allows the flow of exhaust gas to pass through the arrows shown in FIG. 2. It may also be noted that the shape of the inner wall 12 of the transverse portion of the plug connects to the internal faces of the walls 6-7 of the 1 in front of the opening 13. In addition, its inclination relative to the flat walls decreases continuously downstream with respect to the direction of the gas. It thus facilitates the passage of the exhaust gases by deflecting them in the direction of the duct 1 after the elbow formed by the device for these gases. In this way, the plug 5 forms a flow control means for modulating the supply of the cylinder through the conduit 1 between two extreme situations, a feed with only feed gas and feed with only recirculated exhaust gas.
- this bushel on the power module does not require to change the general architecture.
- the plug 5 placed on the second position, in the closed mode of the duct 1 is not invasive with respect to the empty volume 2 in the manifold 3. It allows the intake gases freely to be distributed to the other cylinder ducts engine whose mouth is not blocked.
- the opening 13 being formed in the boss 8 of the plug 5 the assembly can integrate into the admission duct 1 on the height available in the part of the module of amission intended to interface with the breech.
- the wall 7 where is practiced the intake opening 13 of the recovered exhaust gas gives on a face of the manifold 3 intended to be above the cylinder head of the engine equipped. It is therefore easy to adapt a conduit to bring the exhaust.
- a controllable valve is advantageously installed in front of the opening 13 bringing the exhaust gases in front of the plug 5, in order to be able to seal this exhaust gas supply.
- the valve controls the communication between the conduit 16 giving onto the opening 13 in the feed pipe 1 of the cylinder and an exhaust gas inlet 17.
- this valve 15 is arranged to seal the arrival of the exhaust gas when the plug 5 opens the conduit 1, and to open the communication with the exhaust manifold when the plug 5 closes the conduit 1 .
- the valve 15 may be replaced by a shutter or any other known means for sealing the arrival of the exhaust gas.
