Definitions

  • the present invention relates to an exhaust gas recirculation circuit.
  • a circuit can be used in an internal combustion engine, such as a motor vehicle engine.
  • combustion chamber In an internal combustion engine, the four stages of the thermodynamic cycle - admission of fuel gas and air, compression of the gas mixture, expansion due to the explosion of the mixture, exhaust - take place successively in one and the same enclosure, so-called combustion chamber.
  • the gases introduced into this combustion chamber consist on the one hand of air and on the other hand of gasoline or gas oil, in proportions proportionally dosed according to the engines and ignition systems used.
  • the gas mixture is then ignited in the combustion chamber.
  • FIG. 1 schematically illustrates the principle of an EGR system.
  • An internal combustion engine comprises one or more combustion chambers 10 located between an intake manifold 11 and an exhaust manifold 12.
  • the intake manifold 11 receives air A to be introduced into the combustion chamber 10.
  • a fuel injection is also introduced into the combustion chamber, generally by an injection nozzle (not shown).
  • the exhaust manifold 12 receives the emissions of gas produced by the combustion and directs them to an exhaust catalyst 13 adapted to treat the fumes before their expulsion to the outside atmosphere, in a manner known per se.
  • FIG. 1 also shows an exhaust gas recirculation circuit 100.
  • This EGR circuit constitutes a connection 105 between the exhaust manifold 12 and the intake manifold 11 and comprises a regulation valve 101 at the input of the circuit 100. It is indeed necessary to precisely control the flow rate of the exhaust gases reintroduced into the combustion chamber 10. A too high flow rate causes a loss of engine power and causes acceleration blows, while a flow too much. low leads to over-emission of nitrogen oxides.
  • the recirculation circuit 100 also comprises a cooler 102, such as a tube heat exchanger exchanging with the coolant of the motor, so as not to introduce too hot gases in the combustion chamber 10, which would result in a loss of volumetric efficiency.
  • a cooler 102 such as a tube heat exchanger exchanging with the coolant of the motor, so as not to introduce too hot gases in the combustion chamber 10, which would result in a loss of volumetric efficiency.
  • the amount of nitrogen oxide can be reduced by reducing the combustion temperature, in particular by recirculating exhaust gases into the combustion chamber. Indeed, the exhaust gases have already burned and are rich in di-nitrogen (N 2 ) and carbon dioxide (CO 2 ). The recirculated exhaust gas thus dilutes the fuel charge, resulting in slowing and cooling of the combustion.
  • US-A-4 175 523 proposes an internal combustion engine with an EGR system and a catalytic reforming system of the fuel.
  • the combustion chamber receives only the air / fuel mixture and the exhaust gas recirculation.
  • the EGR system is flanged, i.e. it can only provide a recirculated exhaust gas flow rate limited to a predetermined value.
  • the reformed fuel rich in free hydrogen, is added to the air / fuel mixture and to the recirculation of the exhaust gas.
  • the EGR system provides a recirculated exhaust gas flow rate greater than said predetermined value.
  • the power output of the engine is thus improved while limiting the emissions of carbon products.
  • This methanation reaction can be avoided by promoting the reaction of gas with water which removes CO, for example by placing in excess of water.
  • the most efficient reforming reaction for producing hydrogen is the steam reforming reaction which has the highest efficiency. This vapo-reforming reaction is favored by high temperatures and an excess of water vapor.
  • document FR-A-2 839 583 describes a fuel cell installation for a motor vehicle comprising, in addition to the internal combustion engine, a fuel cell operating with a fluid containing hydrogen.
  • the hydrogen necessary for the proper functioning of the fuel cell is generated on board the vehicle, using a reformer.
  • the reformer is adapted to provide a hydrogen enriched fluid from a mixture containing hydrocarbons.
  • the document FR-A-2 839 583 proposes placing a heat exchanger on the exhaust gas duct of the internal combustion engine to heat a heat transfer fluid intended to heat the reformer.
  • the thermal energy required for an optimal reforming reaction is therefore provided by the heat of the exhaust gas.
  • the dual system of EGR and fuel reforming described in US-A-4 175 523 cited above is complex and cumbersome.
  • the two systems comprise separate gas flow circuits from one another.
  • the reformed gas rich in hydrogen is stored in a tank and introduced into the intake manifold of the combustion chamber only when the engine exceeds a certain speed, while the exhaust gas is recirculated in the combustion chamber. regardless of the operating speed of the engine.
  • the exhaust gas recirculation circuit comprises a gas flow connection adapted to extend between an exhaust manifold and an air intake manifold of a combustion chamber of an engine.
  • the recirculation circuit also comprises a hydrogen reformer disposed on the gas flow connection.
  • the EGR circuit provides the air intake manifold of the combustion chamber a recirculating gas enriched in hydrogen.
  • the hydrogen enrichment of the gas mixture supplied to the air intake manifold does not come from a system separate from the EGR circuit, but from the EGR circuit itself. An improved EGR system is thus provided by the present invention.

  • the recirculation circuit according to the invention further comprises a hydrogen reformer 200 disposed on the connection 105 of gas flow.
  • a hydrogen reformer 200 disposed on the connection 105 of gas flow.
  • the lime exhaust gases taken at the inlet 106 of the gas flow connection must not be cooled before having passed through the reformer 200. Any control valve, which would introduce an adiabatic expansion of the gas flow, is therefore proscribed at the entrance 106 of the link.
  • the EGR circuit according to the invention may comprise a cooler 102 disposed downstream of the reformer 200.

  • the fuel and water can be injected in liquid form, which is the form in which they are stored, in an evaporator 220 coupled to the mixer 210 to provide the fuel and water in the form of vapors.

At this level of the connection, the gas is very hot, of the order of 400 to 500 ° C, and can be used in all or part of heat transfer fluid to heat the evaporator 220 to vaporize the water and the fuel. inject into the mixer 210.
  • the reformer 200 also comprises at least a first catalytic module 250 adapted to cause a vapor reforming reaction of the fuel.
  • An obstacle may be disposed on the gas flow connection 105 upstream of the first catalytic module 250 to make the flow of the gaseous flow turbulent and thus promote the mixing of the gases.
  • the obstacle may be placed upstream of the mixer 210 to render the gaseous flow of the exhaust gas taken into the mixer turbulent, this turbulence being sufficient to mix the gas flow with the injected fuel and water vapors. in the mixer.

  • a control unit (not shown) of the reformer 200 is provided.
  • This control unit is generally connected to a control unit of the engine speed and in particular to a control unit adapted to control the gas flow control valve in the recirculation circuit.
  • This valve determines the amount of recirculated exhaust gas introduced into the intake manifold of the combustion chamber.
  • the amount of recirculated gas will determine the amount of gaseous mixture enriched in hydrogen to be added, that is to say the amount of fuel to reform.

  • the engine injection system in order to control the composition of the gases at the inlet of the EGR circuit, the engine injection system must have dedicated settings.
  • the amount of oxygen present in the EGR circuit depends on the combustion in the engine, that is to say if it is in excess or not.

  • the vapo-reforming reaction is highly endothermic. It is therefore necessary that the exhaust gases are hot enough to guarantee the reaction. This constraint implies that the reformer placed on the EGR link can only operate when the engine is hot enough, the control unit preventing the injection of fuel and water until the engine has reached a temperature predetermined.
  • the reformer With an air injection into the reformer, it is then possible to produce hydrogen at any time of the engine operation, including when the engine is still cold.
