Description

Air inlet loop connector
Technical Field
The present invention relates to an intake circuit connector. The invention also relates to a combustion engine or a heat engine comprising such an inlet circuit connector. The invention also relates to a motor vehicle comprising such a combustion engine.
Background
Combustion engines, especially those mounted to motor vehicles, require fresh air to operate, which is directed into the combustion chamber through an air intake circuit. The combustion of fuel in the combustion chamber produces gases that are exhausted through an exhaust circuit.
Combustion engines or heat engines typically include an Exhaust Gas Recirculation (EGR) system. Such EGR systems are typically used to reduce polluting emissions and/or optimize engine power. A greater or lesser proportion (also referred to as an EGR ratio) of exhaust gas is redirected from the exhaust circuit of the engine to the air intake circuit. In the remainder of this description, exhaust gas redirected from the exhaust circuit of the engine to the air intake circuit is referred to as EGR gas.
The EGR system makes it possible to reintroduce the gases burned during the previous combustion into the combustion chamber. Such a system requires EGR gas to be mixed with fresh air. For this purpose, mixers are generally used, which are referred to as air-EGR mixers in the rest of the description. However, such mixers are very bulky compared to other elements of the combustion engine. Furthermore, such mixers can lead to pressure losses in the air intake circuit of the combustion engine.
Disclosure of Invention
The object of the present invention is to provide a system which proceeds to solve the above-mentioned drawbacks and to improve the systems known in the prior art. In particular, the present invention proposes a valve system that makes it possible to form a combustion engine that does not comprise an air-EGR mixer.
In order to achieve this object, the invention relates to an intake circuit connector, in particular for a heat engine of a motor vehicle, comprising a tubular section intended for the circulation of fresh air and a flow obturator intended for the circulation of conditioned air, characterized in that a duct intended for the circulation of gas protrudes into the section downstream of said obturator and immediately adjacent thereto.
Advantageously, the conduit intended for the gas circulation may be introduced in the upstream direction of the section.
Advantageously, the conduit intended for the gas circulation may be introduced into the section in the region of high air flow and strong turbulence generated by the flow obturator.
The protruding access opening of the duct may be inclined in the section so as to form an angle between the main direction of the section and the main direction of the duct of between 10 ° and 80 °, in particular between about 10 ° and 80 °, for example about 45 °, in particular such that the second gas flow circulating in the duct is introduced in countercurrent flow or countercurrent flow into the first air flow circulating in the tubular section.
The flow obturator may have a closing percentage of less than or equal to 90%.
The conduit may protrude into the tubular section by a protruding height, for example, less than or equal to one-half the diameter of the tubular section, for example, approximately equal to one-fourth the diameter of the tubular section.
The distance from the end of the catheter protruding into the tubular section to the flow obturator in a direction perpendicular to the main direction of the tubular section may for example be less than or equal to one half the diameter of the tubular section.
The distance from the end of the catheter protruding into the tubular section to the flow obturator in the main direction of the tubular section may for example be between 0.5 and 2 times the diameter of the flow obturator, for example approximately equal to one half the diameter of the flow obturator.
The shape of the cross section of the protrusion of the catheter may be elongated in a plane containing the main direction of the tubular section.
The invention also relates to a combustion engine comprising a connector as defined above.
Finally, the invention relates to a motor vehicle comprising a combustion engine as defined above or a connector as defined above.

Detailed Description
The air intake circuit of the combustion engine may include an air intake valve intended to regulate the flow of oxidant air into the combustion chamber. The present invention proposes to make use of the presence of such an air inlet valve in the engine, so that the use of an air-EGR mixer in the engine can be dispensed with. The air inlet valve is intended to act as a mixer of air and EGR gas, in addition to its function of regulating the flow of oxidant air. The inlet valve then also acts as a valve for metering EGR gas. For this purpose, a conduit intended to channel the EGR gas is connected directly to the air inlet valve at a judiciously chosen position. This makes it possible to introduce EGR gas into the air intake circuit while mixing it with fresh air. As a result of this, an engine provided with such a valve does not require an air-EGR mixer and is therefore particularly reduced in volume.
In the remainder of the description, the expression "intake circuit connector" denotes a valve system comprising a conduit, in particular a conduit intended to channel EGR gas.
Fig. 1 schematically shows an embodiment of an intake circuit connector 1. The intake circuit connector 1 comprises a tubular section 3. The tubular section 3 is intended for circulation or passage of a first fluid, preferably air, more preferably fresh air. The intake circuit connector 1 further comprises a flow obturator 5. The flow obturator 5 aims at regulating the circulation or flow of a first fluid (for example air) in the tubular section 3 (referred to as first flow). The direction of circulation of the first flow of the first fluid in the tubular section 3 is indicated by arrow 7. The inlet circuit connector 1 further comprises a conduit 9 connected to the tubular section 3 downstream of the flow obturator 5. The conduit 9 protrudes into the tubular section 3 downstream of and immediately adjacent to the flow obturator 5. The conduit 9 is intended for circulation of a second fluid, preferably EGR gas, and for introduction of the second fluid into the tubular section 3. The direction of circulation of the flow of the second fluid in the conduit 9, called second flow, is indicated by arrow 11.
The term "fresh air" is understood to mean air which is introduced into the air intake circuit for the first time, in other words air which has never been previously fed into the combustion chamber.
When the first fluid circulates in the tubular section 3, there is an inherent pressure loss in the tubular section 3. Advantageously, the conduit 9 opens into the tubular section 3 downstream of the flow obturator 5 in the region of high air flow and/or pressure losses and/or turbulence or intense turbulence generated by the flow obturator 5. The second fluid is thus introduced into this turbulence, which makes it possible to minimize the pressure loss associated with the introduction of the second fluid into the tubular section 3. This also makes it possible to optimize the mixing of the first fluid with the second fluid.
A conduit 9 is connected to the tubular section 3, protruding into the tubular section 3. For example, the conduit 9 is installed by punching into the tubular section 3, in other words into the body of the air intake circuit connector 1.
The conduit 9 protrudes into the tubular section 3 with a protruding height h. The protruding height h of the conduit 9 in the tubular section 3 is for example less than or equal to half the diameter D of the tubular section 3. Preferably, the protruding height h of the conduit 9 in the tubular section 3 is for example approximately equal to one quarter of the diameter D of the tubular section 3.
Advantageously, the duct 9 opens in the upstream direction of the tubular section 3. Advantageously, the protruding access opening of the duct 9 is inclined in the section 3.
The tubular section 3 extends in a main direction Δ1. The conduit 9 extends in a main direction Δ2. The main direction Δ2 of the conduit 9 forms an angle Φ with the main direction Δ1 of the tubular section 3.
Advantageously, the conduit 9 is connected to the tubular section 3 such that the main direction Δ1 of the tubular section 3 and the main direction Δ2 of the conduit 9 form an angle Φ between 10 ° and 80 °, in particular between about 10 ° and about 80 °, preferably about 45 °. The angle Φ between the main directions Δ1, Δ2 of the tubular section 3 and the conduit 9 is chosen such that the second flow of the second fluid circulating in the conduit 9 is introduced in countercurrent flow or countercurrent flow into the first flow of the first fluid circulating in the tubular section 3. As a result of this, the first and second streams interact, which makes it possible to obtain a mixture between the first and second fluids.
According to an exemplary embodiment, the intake circuit connector 1 comprises an oxidant intake valve and is intended for a combustion engine. The tubular section 3 is intended, for example, for channeling air (e.g., fresh air), in particular for introducing oxidant air. The conduit 9 is for example intended for guiding a gas (e.g. EGR gas) with a channel. The conduit 9 may also be intended for guiding a blow-by gas (which refers to the discharge of gas), for example, with a channel, or for guiding fuel vapor with a channel.
Preferably, the valve of the intake circuit connector 1 has a small percentage of closure. This is particularly useful for avoiding fouling of the inlet circuit connector 1 due to the introduction of EGR gas into the tubular section 3.
The expression "percentage of closure" is understood to mean the percentage of closure compared to the open position of the flow obturator 5 corresponding to the rest position. A closing percentage of 0% corresponds to an open position of the flow obturator 5, and a closing percentage of 100% corresponds to a fully closed position of the flow obturator 5.
Advantageously, the percentage of closure of the flow obturator 5 is less than or equal to 90%, preferably less than or equal to 50%, more preferably less than or equal to 20%. Thus, the intake circuit connector 1 is not susceptible to scaling.
The distance D1 from the end of the conduit 9 protruding into the tubular section 3 to the flow obturator 5 in a direction perpendicular to the main direction Δ1 of the tubular section 3 is for example less than or equal to one half the diameter D of the tubular section 3. Preferably, the distance D1 is for example approximately equal to one quarter of the diameter D of the tubular section 3.
In the main direction Δ1 of the tubular section 3, the distance D2 from the end of the conduit 9 protruding into the tubular section 3 to the flow obturator 5 is for example between 0.5 and 2 times the diameter D5 of the flow obturator 5. Preferably, the distance D2 is for example approximately equal to one half the diameter D5 of the flow obturator 5. Advantageously, the duct 9 is arranged as close as possible to the zone of turbulence of the tubular section 3, which turbulence is created by the flow obturator 5.
As shown in fig. 1, the distances d1 and d2 are measured, for example, between the center of the flow obturator 5 and the center of the cross-section of the end of the catheter 9 protruding into the tubular section 3.
The shape of the cross-section of the protrusion of the duct 9 is for example elongated in a plane P containing the main direction Δ1 of the tubular section 3 and maximizing the angle formed between this plane and the main direction Δ2. The diameter of the cross section of the protruding portion of the catheter 9 is for example approximately D/5. The shape and size of the cross-section of the protrusion of the conduit 9 will be chosen for example according to the EGR gas flow demand.
According to an exemplary embodiment, the valve 1 is of the type having a flap. The flow obturator 5 is then, for example, a flap.
The operation of an air inlet circuit connector 1 such as that of fig. 1 will be described hereinafter with reference to fig. 2 and 3.
Fig. 2 schematically shows the air inlet circuit connector 1 in operation when no second fluid, such as EGR gas, is introduced into the tubular section 3.
The flow obturator 5 is in an open position, in a rest position.
The valve 21, which is not shown in fig. 1 but is shown in fig. 2, is arranged in the conduit 9 upstream of the conduit, that is to say at the end of the conduit 9 opposite to the end protruding into the tubular section 3.
The conduit 9 is closed by a valve 21. Thus, the second fluid is not introduced into the tubular section 3.
Arrow 23 represents a first flow of a first fluid in the tubular section 3. As schematically shown in fig. 2, the presence of the conduit 9 connected to the tubular section 3 and protruding into the tubular section 3 causes only a small pressure loss in the tubular section 3. Thus, the valve 1 operates as if there were no conduit 9.
However, there may be a slight air disturbance (a raulique perturbation) in the tubular section 3, in particular in the region 25 upstream of the end of the conduit 9 protruding into the tubular section 3.
Advantageously, the protruding height h of the duct 9 into the tubular section 3 can be reduced in order to reduce the phenomenon of air turbulence in the tubular section 3. The protruding height h is selectable, in particular by balancing the angle Φ between the main directions Δ1, Δ2 of the tubular section 3 and the conduit 9, which serves to minimize the air turbulence phenomenon in the tubular section 3 while ensuring an optimal quality of mixing between the first fluid and the second fluid.
Fig. 3 schematically shows the air inlet circuit connector 1 in operation when a second fluid, such as EGR gas, is introduced into the tubular section 3.
The flow obturator 5 is inclined at an angle ω with respect to the main direction Δ1 of the tubular section 3. The inclination angle ω of the flow obturator 5 with respect to the main direction Δ1 of the tubular section 3 is for example between 0 ° and 20 ° (for example about 20 °).
Arrow 33 represents a first flow of a first fluid in the tubular section 3. As illustrated by arrow 33 in fig. 3, the inclined position of the flow obturator 5 with respect to the main direction Δ1 of the tubular section 3 generates a pressure loss in the tubular section 3. This creates a reduced pressure area allowing the second fluid to be introduced into the tubular section 3.
Arrow 35 represents the second flow of the second fluid in the conduit 9. The conduit 9 makes it possible to introduce the second fluid into the tubular section 3 under aerodynamic disturbance of the first fluid. After the introduction of the second flow of the second fluid into the tubular section 3, the flows of the first and second fluids downstream of the end of the conduit 9 protruding into the tubular section 3 have little pressure loss, as illustrated by arrow 37 in fig. 3. Thus, the inlet circuit connector 1 makes it possible to obtain a homogeneous mixture of the first fluid (which is, for example, air) and the second fluid (EGR gas, for example) at its outlet. In addition, the mixing of the first fluid and the second fluid causes a reduction in pressure loss. Thus, the intake circuit connector 1 acts as a mixing valve.
One advantage of an intake circuit connector, such as that described with reference to fig. 1-3, is that it acts as a flow regulator for the first fluid and as a mixer that mixes the first and second fluids. When such an intake circuit connector is arranged in a combustion engine, for example, it is made possible to dispense with the use of an air-EGR mixer. The outlet of the inlet circuit connector produces a homogeneous mixture of the first fluid, which is for example air, and the second fluid, for example EGR gas, while the pressure loss in the inlet circuit of the first fluid has been minimized.
Fig. 1 to 3 show the inlet circuit connector 1 in the case where the main direction Δ2 of the conduit 9 is positioned in a plane perpendicular to the plane of the flow obturator 5.
Reference numeral α denotes the angle formed between the plane of the flow obturator 5 and the orthogonal projection of the main direction Δ2 of the duct 9 on a plane perpendicular to the direction Δ1 when in the rest position, the open position. In the exemplary embodiment of fig. 1-3, the angle α is approximately 90 °.
According to a variant, the main direction Δ2 of the duct 9 can be positioned in the plane of the flow obturator 5. The angle α is then 0 °. Any other orientation of the main direction Δ2 of the conduit 9 relative to the plane of the flow obturator 5 may also be chosen. The value of the angle alpha should be chosen between 0 deg. and 360 deg., depending on the geometry of the intake circuit connector upstream of the flow obturator 5. The optimum value of the angle alpha should be determined, for example, by means of aerodynamic calculations.
The invention has been described with reference to fig. 1 to 3 in the case of a valve 1 of the type having a flap. According to a variant, the valve 1 may be of the type having a sliding shutter.
An intake circuit connector, such as the one described with reference to fig. 1-3, may be used for the combustion engine (or heat engine) 41. Such an intake circuit connector makes it possible to dispense with the use of an air-EGR mixer in a combustion engine. This results in a more compact combustion engine.
The invention also relates to a motor vehicle 51 comprising such a combustion engine 41 or an intake circuit connector (such as the intake circuit connector described with reference to fig. 1-3).
The connector (such as that described with reference to fig. 1-3) may be used in any type of application where mixing of two fluids is desired, one of which is regulated in flow by a valve. Such a connector may be used in a boiler, for example.
