Definitions
- the invention concerns, with reference to FIG. 7 in the appendix, the EGR loop of an internal combustion engine of a motor vehicle, comprising the engine 21, an exhaust manifold 22 for the combustion gases, a turbine 25 of turbo-compressor 24, the exhaust gas recirculation loop (EGR) 28, with a cooler 29 and the low-pressure three-way valve disposed upstream of the compressor 26 of the turbo-compressor 24 and connected to it by its output and having two inlets for receiving fresh air and the cooled exhaust gas, in a mixture whose pressure is increased in the compressor 26, and an intake manifold 23 of the engine for receiving the exhaust gas and the compressor air.
- EGR exhaust gas recirculation loop
- the EGR loop aims to reduce the emission of nitrogen dioxide, by reducing the combustion temperature, by slowing down the combustion of the combustion mixture and absorbing part of the calories.
- the cooler of the EGR loop makes it possible to lower the combustion temperature at high speed (high load).
- the engine may only receive fresh air with no recirculated exhaust.
- the engine can receive fresh air mixed with a portion of the exhaust gas, the pressure difference between the exhaust and the inlet of the compressor of the turbo-compressor being sufficient to ensure the recirculation of the exhaust gas.
- the pressure difference is not sufficient for the exhaust gas recirculation and to ensure the correct EGR rate, it is possible to create throttling back pressure downstream of the EGR loop, so that force a portion of the exhaust gas to the engine intake lane.
- This solution by its complexity, is however not very satisfactory and the invention of the present application is another solution to the problem of creating a back pressure to ensure a correct flow EGR.
- the invention relates to a particular mode of use of the EGR loop above, characterized by the fact that
- the EGR gas channel is progressively opened in the valve and
- the invention is implemented with a two-way three-way valve for the two fresh air and EGR gas channels, respectively.
- phase shift of the closure of the fresh air intake channel can also be achieved with a three-way valve monovolt, involving angular areas much narrower.
- the flow of EGR gas in the inlet channel EGR of the valve begins to decline after a rotation of the corresponding flap of about 55 ° It is in this angular position of the EGR gas shutter that the intake flap of the fresh air is started to close the fresh air inlet in the EGR valve.
- the rotation of the intake flap (5) can be carried out until it is rotated 90 °. This rotation can lead to completely close the air inlet (2).
- the pipe is closed only partially, for example by a flap whose diameter is smaller than the diameter of the pipe.
- FIGS. 2a, 2b and 2c show the air flow curves (1a), the natural flow rate of exhaust gas EGR (dgn) and the flow rate, forced according to the invention, of exhaust gas EGR (dgf). ), as a function of the angular positions ( ⁇ ) of the corresponding flaps;
- FIG. 3 is a perspective view of the kinematics of the three-way valve with two flaps, open air flap and shutter gas closed;
- FIG. 4 is a view of the valve of FIG. 3, flap of gases in the partial open position;
- FIG. 5 is a view of the valve of FIG. 3, open gas shutter and closed air shutter;
- FIG. 6 is a partial perspective view of the kinematics of a three-way valve according to a variant of the temporal phase-shift mechanism of the closure of the air shutter with respect to the opening of the flap of gases and
- FIG. 7 shows a simplified way, the EGR loop used according to the invention.
- the EGR valve 1 of FIGS. 1a, 1b, 1c schematically, comprises an air inlet 2, a recirculated exhaust gas inlet 3 and an air and gas outlet 4.
- the valve 1 is here a two-part valve, a flap 5 in the air inlet duct 2 and a flap 6 in the gas inlet duct 3.
- the air flap 5 is in an angular position (0 °) allowing a maximum air flow in the track 2 and the arrival flap of the gases 6, in an angular position (90 °) shutting off way 3.
- the gas inlet flap 6 begins to pivot to gradually open the track 3 EGR exhaust gas (Figure 1a). This is the zone I of the curves 2.
- This zone III extends until the gas flap 6 reaches the maximum opening angular position O 0 of the gas inlet port 3 and the air flap is in the angular position (90). °) total or partial closure of the air inlet 2.
- this three-way valve has the kinematics which will now be described with reference to Figures 3 to 5.
- the kinematics of the three-way valve 1 comprises a gear extending, here, between a DC motor 7 and two shafts 51, 61 for rotating the air flap 5 and the flap of the gas 6, respectively.
- the two shafts 51, 61 extend parallel to each other.
- the shaft 14 of the motor 7 is secured to a pinion 8 driving an intermediate gear 9 having a peripheral toothing 10 and a central toothing 11.
- the peripheral toothing 10 of the intermediate wheel meshes with a ring gear 12 for rotating the air flap 5.
- the ring gear 12 is free to rotate relative to the axis 51 of the flap 5.
- the rotational drive this flap 5 by the ring 12 is via a drive finger 15 which is itself integral in rotation with the axis 51 of the flap 5.
- This finger 15 is disposed at rest against an adjustable stop 16 integral with the body of the valve (not shown).
- the ring 12 has an angular notch 17 adapted to allow the free rotation of the ring 12 on a defined angular sector, without driving the finger 15, that is to say the flap 5. It is when the ring 12 is driven in rotation beyond this angular sector, in one direction or the other, that the edge of the notch 17 then drives the finger 15.
- the central toothing 11 of the intermediate wheel 9 meshes with a ring gear 13 for rotating the flap of the gas 6.
- the ring gear 13 is rotationally integral with the axis 61 of the flap 6.
- the flap 6 is therefore rotated directly by the rotation of the ring 13, while the flap 5 is rotated only when the ring 12 rotates the finger 15.
- the wheel 9, by its teeth 10, 11 drives, in the opposite direction of the needles, the two toothed rings 12, 13, which are thus rotated by the same intermediate wheel 9, but via two gear teeth 10, 11.
- the gear ratio between the shaft 14 of the motor 7 and the flap of the gas 6 is here 15.67, the ratio between the shaft 14 and the air flap 5 when is driven being 6.67.
- Figures 3, 4 and 5 show the crowns and toothed wheels at different stages of rotation of the pinion 8.
- phase shift mechanism An alternative embodiment of the phase shift mechanism is shown in Figure 6.
- a cross member 50 with two radial arms 52, 53 is mounted on the shaft 51 of the flap 5.
- Each of the arms 52, 53 has at its end a drive finger 54, 55, extending substantially parallel to the shaft 51.
- the fingers 54, 55 extend respectively in these two lights 56, 57.
- the shaft 51 and the air shutter 5 can not be rotated.
- the ring gear 12 drives them with it, causing the flap 5 to rotate.
- the angular opening of the lights must be less than 180 °. If ⁇ g is the angle of rotation of the gas flap 6, ⁇ a , the angle of rotation of the air flap 5, the relation (1) must be satisfied.
- the circular lights 56, 57 are formed in the ring 12 relative to the toothed sector of the ring 12 taking into account the amplitude of the angular rotation of the gas flap 6 before the air flap 5 begins to rotate.
- valve that has just been described is remarkable for its uniqueness of control, at the single level of the DC motor 7, which makes it a better price and a smaller footprint.
- This control can be achieved using an H bridge, well known to those skilled in the art, with two pairs of switches in series and the component to be controlled - here the motor - connected to the two middle points of two pairs of switches, the two pairs being connected between a battery voltage and ground.
