Definitions
- the invention relates to a system for recovering energy in an exhaust gas circuit.
- the invention relates to motor vehicle heat engines, which generally need incident gases to ensure in each combustion chamber, in connection with the fuel injected, a satisfactory combustion, the exhaust gases from this combustion being then released to the atmosphere after being cleared.
- these exhaust gases which are brought to a certain temperature, rather than being removed from the vehicle without a particular function, can be reused within the same vehicle, for example to participate in the heating of the vehicle or to be redirected to the incident gases, to improve the combustion conditions in each of said chambers.
- the invention relates to an optimized energy recovery system, based on the use of these exhaust gases.
- patent FR2933746 which relates to a bypass duct implanted at the level of the exhaust circuit, downstream of a recycling system, said bypass duct making it possible either to convey the gases of exhaust in the air intake circuit, or to recover energy by heating a heat transfer fluid flowing in the heat exchanger.
- the exhaust gases are hot and can be re-routed as such in the intake circuit, or be previously cooled by the exchanger before reaching said intake circuit.
- These different configurations of use of this bypass duct are controlled by a first valve located in the exhaust circuit, downstream of the recycling system and upstream of the heat exchanger of said bypass duct, and by a second valve located downstream of said heat exchanger.
- This second valve comprises a shutter pivotable between an open position, for which it allows the exhaust gases from the heat exchanger to pass, to join the intake circuit, and a closing position for which the exhaust gas is condemned to circulate in the heat exchanger, before being released into the atmosphere by an exhaust system outlet.
- the bypass duct comprises two inlet pipes located in parallel on the exhaust circuit, a first pipe joining a first passage compartment of the exchanger, and a second pipe joining a second compartment of the exchanger, in which circulates a fluid, for example being the cooling water of the engine, said compartments being in communication with each other.
- the first valve comprises a flap pivotally mounted and adapted to occupy three distinct positions to reconstitute, in combination with the position of the flap of the second valve, the three main configurations of use of this bypass duct.
- a first position of the flap of the first valve corresponds to a closure of the first manifold. A part of the exhaust gas then rushes into the second pipe to reach the second compartment of the heat exchanger where they are cooled. By opening the shutter of the second valve, the cooled exhaust gases from the heat exchanger will be routed to the intake circuit to mix with the incident gases.
- a second position of the shutter of the first valve corresponds to a closure of the exhaust circuit between the two pipes, this second position being deduced from the first position by a 90 ° rotation of said flap.
- the hot exhaust gases all pass through the first manifold to end up in the first compartment of the exchanger. By closing the flap of the second valve, the hot exhaust gases will then transit to the second compartment and heat the fluid present in said second compartment, before passing through the second manifold and then being discharged from the vehicle through an outlet of the second compartment. exhaust system.
- a third position of the shutter of the first valve corresponds to a closure of the second manifold, this third position is deriving from the second position by a 90 ° rotation of said flap, and deduced from the first position by a rotation of 180 °.
- Part of the exhaust passes through the first manifold and invades the first compartment of the exchanger.
- the flap of the second valve When the flap of the second valve is in a closed position, the exhaust gases are circulated in a loop in the exchanger, entering through a pipe, then through the two compartments, before being evacuated by the other manifold to the exhaust system. If the flap of the first valve closes one of the two pipes, the flap of the second valve must be open, otherwise there is a build-up of gas in the heat exchanger, without the possibility of leakage.
- the energy recovery system described in this patent involving in particular the two valves and the bypass duct equipped with a heat exchanger, makes it possible to use the bypass duct, or to make the recirculation of hot exhaust gases. or cold, either to do energy recovery.
- the functions of energy recovery and gas recirculation are completely decoupled here, and can only be provided as an alternative. However, it may happen that for certain phases of use of the engine, especially for cold starts, it is necessary to quickly raise the engine temperature, while ensuring a good cleanup of gases.
- An energy recovery system makes it possible to meet these two requirements by coupling the functions of energy recovery and recirculation of hot exhaust gases.
- a recirculation phase of the hot exhaust gases in the intake circuit can be interspersed with several energy recovery phases over relatively short times, so as to achieve almost simultaneously the gas recirculation and energy recovery.

By passing through the exchanger only through the first compartment, the exhaust gases undergo no modification.
- the engine can be equipped with a compressor placed in the intake circuit, and a turbine placed in the exhaust system. It is assumed that the first and second valves are driven independently of each other.

- the second valve comprises a movable shutter rotatable and pivotable between a closed position for which it blocks the gas in the exchanger, and an open position for which it allows the passage of gases to the circuit of admission.
- the piloting of this valve is fundamental because it will condition the mode of use of a system of energy recovery according to the invention, either to ensure recirculation or to perform energy recovery.
- the flap rotates between 70 ° and 90 ° to move from its open position to its closed position, said flap being able to be fixed in at least one intermediate position situated between these two positions.
- the opening of the second valve is variable and makes it possible to precisely control the flow of exhaust gas that it It would be desirable to inject into the intake circuit, depending in particular on the use phase of the engine.
- the second valve comprises a second flap controlling the flow rate of the gases in the intake circuit, upstream of the connection point of said second valve on the intake circuit.

This second valve thus ensures complete management of the flow and the quality of the incident gases, which will be injected into the combustion chambers of the engine.

They also have the advantage of improving the cold start conditions of an engine, which is a phase that is always difficult to manage, due to a rather slow rise in temperature of the engine.
