    [0001] The present invention relates to a device for controlling the amount of air introduced at the intake of a supercharged internal combustion engine, in particular a stationary engine or for a motor vehicle or industrial vehicle, and a method of controlling the amount of air for such an engine. In particular, when partial transfer pipes of compressed air lead to the exhaust valves through the cylinder head of the engine. As is widely known, the power delivered by an internal combustion engine is dependent on the amount of fuel introduced into the combustion chamber, itself dependent on the amount of air introduced into the combustion chamber of this engine, amount of air which is also proportional to the density of this air. Thus, it is usual to increase this amount of air by means of compression of the outside air before it is admitted into this combustion chamber. This operation, called supercharging, can be carried out by any means, such as a turbocharger or a driven compressor, which can be centrifugal or volumetric.
    [0002] In the case of supercharging by a turbocharger, the latter comprises a rotary turbine, single flow or double flow, connected by an axis to a rotary compressor. The exhaust gases from the engine pass through the turbine which is then rotated. This rotation is then transmitted to the compressor which, by its rotation, compresses the outside air before it is introduced into the combustion chamber. As is better described in the French patent application No. 2,478,736, it is provided, in order to significantly increase this amount of compressed air in the engine combustion chamber, to further increase the compression of the engine. outside air by the compressor.
    [0003] This is achieved more particularly by increasing the speed of rotation of the turbine and therefore of the compressor. For this, a portion of the compressed air leaving the compressor is deflected to be admitted directly to the inlet of the turbine by mixing with the exhaust gas. This turbine is then traversed by a larger amount of fluid (mixture of compressed air and exhaust gas), which increases the speed of rotation of the turbine and consequently the compressor. This increase in compressor speed thus makes it possible to increase the pressure of the outside air which will be compressed in this compressor and then introduced into the combustion chamber of the engine. By this, the compressed air has a higher density which allows to increase the amount of air contained in the combustion chamber.
    [0004] This type of supercharged engine, although satisfactory, nevertheless has significant disadvantages. Indeed, the flow rate of the compressed air that is admitted to the inlet of the turbine is not properly controlled, which can cause a malfunction of the engine. Thus, by way of example, in the event of too much compressed air being diverted to the inlet of the turbine, the exhaust gases entering the turbine are cooled too much by this air and causes a decrease in overall efficiency of overfeeding. The present invention proposes to overcome the drawbacks mentioned above by means of a device for controlling the amount of air introduced at the intake of a supercharged internal combustion engine which makes it possible to meet all the power demands of the engine. engine. In addition, the embodiment of the present invention proposes to make modifications of the engine cylinder head so that the partial compressed air transfer ducts end up in the vicinity of the exhaust valves, which also promotes their cooling. The conventional compressed air loop is not modified.
    [0005] The invention presented here also makes it possible to transfer the compressed air from the intake to the exhaust even when the mean pressure of the compressed air at the intake is lower than that of the exhaust gases. It only suffices that there are phases during the operating cycle of the engine where the intake pressure is higher than that existing at the exhaust.
    [0006] To this end, the present invention relates to a device for controlling the quantity of air introduced at the intake of a supercharged internal combustion engine, said engine comprising two exhaust gas outlets each connected to a collector of exhausting a group of at least one cylinder, said device comprising a supercharging device comprising a turbocharger with a twin-input turbine connected to said exhaust gas outlets and an outdoor air compressor, and at least one a duct for partially transferring compressed air from the compressor to the turbine inlet, characterized in that the partial transfer duct opens into the cylinder head of the engine at an exhaust valve connected to the inlet of the turbine and comprises valve means controlling the flow of the transferred compressed air. The partial transfer conduit may include a check valve (80, 82).
    [0007] The device may comprise a partial transfer duct opening at the exhaust valves of each of the pistons. The partial transfer ducts may be in communication with a connecting line which derives a portion of the compressed air at the outlet of the compressor.
    [0008] The link line may comprise two branches connected to said partial transfer conduits. The valve means may comprise proportional valves.
    [0009] The device may comprise means for controlling the proportional valves. Said connecting duct may comprise a bypass duct to the intake duct downstream of the cooling and a three-way valve. The invention also relates to a method for controlling the amount of compressed air at the intake of a supercharged internal combustion engine, said engine comprising two exhaust gas outlets each connected to an exhaust manifold of a group of at least one cylinder, said device comprising a supercharging device with a turbocharger with a double inlet turbine connected to said exhaust gas outlets as well as an outdoor air compressor, and at least one transfer duct partial compression of compressed air from the compressor to the inlet of the turbine, characterized in that it consists in causing said conduit to open into the cylinder head of the engine at an exhaust valve connected to the inlet of the turbine and introducing through said conduit a portion of the compressed air exiting the compressor into the exhaust gas inlets of the turbine.
    [0010] The method may include disposing a transfer line at the valves of each of the pistons and controlling the circulation of the compressed air in each of the conduits by means of winnowing. The method may include controlling the bypass air temperature through a short circuit conduit and a three way valve.
    [0011] The other characteristics and advantages of the invention will become apparent on reading the following description, given solely by way of illustration and without limitation, and to which are appended: FIG. 1 which illustrates a combustion engine internal with a schematic representation of the principle of the supercharging device according to the invention; FIG. 2 which shows more precisely one embodiment of the internal combustion engine with its supercharging device comprising partial transfer ducts directly leading to the exhaust valves; FIG. 3 which shows an embodiment of presence by machining in the cylinder head of the engine. In Figure 1, the internal combustion engine 10 comprises at least two cylinders, here four cylinders referenced 121 to 124 from the left of the figure.
    [0012] Preferably, this engine is a direct-injection internal combustion engine, particularly of the Diesel type, but this in no way rules out any other type of internal combustion engine.
    [0013] Each cylinder comprises intake means 14 with at least one intake valve 16, here two intake valves each controlling an intake manifold 18. The intake manifolds 18 terminate at an intake manifold 20 supplied with fuel. by a supply duct 22 for intake air, such as compressed air.
    [0014] This cylinder also comprises exhaust gas exhaust means 24 with at least one exhaust valve 26, here also two valves each controlling an exhaust manifold 28.
    [0015] In the example illustrated, the motor is designed to operate according to a combustion order designated 1-3-4-2. Given this combustion order, the exhaust pipes of the first cylinder 121 and second cylinder 124, which form a first group of at least one cylinder, are connected to a first exhaust manifold 30 with a first outlet The third and fourth exhaust manifolds 122 and 123, which form a second group of at least one cylinder, are connected to a second exhaust manifold 34 which has a second gas outlet. exhaust system 36. The two exhaust gas outlets result in a turbocharger 38 for the compression of air and more particularly to the expansion turbine 40 of this turbocharger.
    [0016] As illustrated in FIG. 1, the turbocharger is a double-inlet turbocharger, better known as a "Twin Scroll" turbocharger. This type of turbocharger comprises the exhaust gas turbine 40 which is connected in rotation by a shaft 42 with a compressor 44. At the turbine, the exhaust gas inlet is divided into two parts. two sections, a first inlet section 46 connected to the first exhaust outlet 32 of the first manifold 30 and a second inlet section 48 connected to the second exhaust outlet 36 of the second exhaust manifold Exhaust 34. The exhaust gas 50 of the turbine 40 is conventionally connected to the exhaust line 52 of the engine. The compressor 44 of the turbocharger 38 has an external air inlet 54 fed by a supply line 56. The compressed air outlet 58 of this compressor is connected to the feed duct 22 of the intake manifold 20 by a pipe 60.
    [0017] Advantageously, it can be provided to place a compressed air cooling radiator 62 on the pipe 60, between the compressor and the pipe 22.
    [0018] As can be better seen in FIG. 1, a transfer duct 64 makes it possible to circulate a portion of the compressed air leaving the compressor 44 to the inlets 46 and 48 of the turbine.
    [0019] This configuration shown in FIG. 1 makes it possible to better understand the principle of the invention by clearly describing the different compressed air circuits, however the present invention is preferably made according to FIG. 2, where the partial transfer ducts, or "Sweep", end at the exhaust valves, in the cylinder head of the engine.
    [0020] According to FIG. 1, the partial transfer duct originates on the duct 60, at a point of intersection 66 between the compressor and the cooling radiator 62, and then separates, from a junction point 68 in two branches 70 and 72. The branch 70 leads to the inlet 46 of the turbine by its junction with the first exhaust outlet 32 and the branch 72 leads to the other inlet 48 of this turbine by its In each branch, there are valve means 74 and 76, such as a proportional valve, controlled by a control means 78, which can be common to both valve means. This valve thus makes it possible to control the circulation of the compressed air circulating in the branch. Advantageously, each branch also comprises a non-return valve 80 and 82, which has the advantage of being fast and able to open and close several times per engine cycle. This valve prevents the flow of compressed air from the branch to the compressor while preventing the communication of the two branches. This configuration thus makes it possible, during the operation of the engine and on the scale of the engine cycle, to take advantage of the low exhaust pressure zones 30 punctually prevailing in the exhaust manifolds to introduce compressed air into the turbine and thereby increase the flow rate of this turbine and therefore the compressor. This also allows for more efficient boosting for low revs. During operation, if there is a need for a large quantity of air in the cylinders, the valves 74 and 76 are controlled in opening to introduce compressed air from the compressor 44 into the turbine 40. The compressed air leaving the The compressor 44 circulates in the duct 64 and then in the branches 70 and 72 to reach the exhaust gas inlets 46 and 48 of the turbine 40, bringing a surplus of fluid to this turbine. Thus, the turbine is traversed not only by the exhaust gas from the outlets 32 and 36, but also by compressed air which is added to these gases. As a result, the rotation of the turbine is increased, which causes an increase in the rotation of the compressor and, consequently, an increase in the pressure of the compressed air coming out of this compressor. Of course, the valves 74 and 76 are controlled by the control means 78 to admit the amount of compressed air in the turbine that meets the engine boost requirements. Figure 2 describes an example of an embodiment according to the invention. Here, the compressed air loop at the intake of the engine is not changed between the output of the compressor 38 and the intake manifolds 18. Also, the exhaust loop, and in particular the part that feeds the turbine 40, is not modified. The embodiment of the present invention relates to the presence of partial compressed air transfer ducts which open into the body of the cylinder head of the engine, at the exhaust valves. Thus, at each of the pistons 121, 122, 123, 124, a partial transfer conduit 130, 131, 132, 133 opens into the cylinder head at the exhaust valves.
    [0021] 3036 73 8 9 The compressed air inlet to the valve stem by machining in the cylinder head promotes the cooling of the entire exhaust duct and especially the valve shanks. In addition, the gases at the inlet of the turbine are better homogenized and thus important temperature gradients are avoided. Finally, it limits the thermal losses of the entire exhaust duct and the collector by lowering the temperature of the exhaust duct from the valves.
    [0022] In the partial transfer ducts, there is a 76-74 air flow control valve and a check valve to prevent reflux of the exhaust gases into the inlet. This valve can be arranged upstream or downstream of the valve, or even be integrated with the valve 76-74. The partial compressed air transfer pipes leading to valves 15 connected to the same manifold, 30 or 34, meet in a pipe 170-172 constituting the two branches of the connecting pipe 64 in bypass downstream of the compressor 44. valve means may consist of two valves 74-76, in particular proportional, each disposed on the two branches 170 and 172. Check valves 80-82 equip the two branches to prevent a return 20 of the exhaust gas in the engine. 'admission. In a variant, a single valve 180, in particular a proportional one, disposed on the connecting pipe 64 makes it possible to control the flow of compressed air circulating in the partial transfer ducts.
    [0023] In another variant, a short-circuit conduit 164 makes it possible to send or draw off a compressed air flow rate controlled by a three-way valve 166 on the connecting pipe 64. This bypass duct makes it possible to control the compressed air temperature of a mixture of air upstream and downstream of the charge air cooler 62.
    [0024] Figure 3 shows a schematic section in the cylinder head 100 of an engine. The references 101 and 102 respectively represent the intake and exhaust ducts which lead to the intake and exhaust valves 104 and 103. The arrow 105 schematically represents the machining of the arrival of a partial transfer duct 5. at the exhaust valves. Depending on the type of yoke, this machining may be a bore or be provided for the casting of the cylinder head. This diagram represents a valve arrangement that is typically found on industrial engines. Thus, it is possible to easily integrate an air intake as mentioned above. The embodiments are not limited to those exemplified in FIG. 2, the other equivalent arrangements in the transfer duct yoke can be envisaged, in particular depending on the type of cylinder head or engine. In particular, it is possible to provide an intake of short-circuited air in a sole contiguous to the yoke at the cylinder head outlet with an air guide towards the inside of the duct via a specific machining or pipework.
