Definitions

  • the present invention relates to internal combustion engines 4 controlled self-ignition time.
  • Controlled self-ignition is a known phenomenon in 2-stroke engines. This type of combustion has advantages over level of pollutant emissions: low levels of hydrocarbon and nitrogen oxide emissions. In addition, a remarkable cyclic regularity is achieved during combustion in auto-ignition.
  • Self-ignition is a phenomenon that allows you to initiate combustion with residual flue gas remaining in the chamber of combustion after combustion.
  • Self-ignition is achieved by controlling the amount of gas Residuals and its mixture with fresh gases (not yet burned). Gas residuals (hot flue gases) initiate the combustion of the fresh gases through a combination of temperature and the presence of active species.
  • Controlled auto-ignition technology applied to the engine four times is particularly interesting because it allows to do operate this type of engine with an extremely diluted mixture, with very low wealth and, consequently, emissions of oxides ultra-low nitrogen.
  • Patent application FR-97 / 02,822 filed in the name of the Applicant describes a control of self-ignition in an engine four times. More precisely, this document recommends, dependent partial, to minimize the mixing of fresh gases with the flue gases enclosed in the combustion chamber, acting on the closure of the exhaust. It is therefore a solution close to the technique of "internal" recycling that allows stratifying the gases in the chamber of combustion.
  • the present invention aims to achieve controlled self-ignition in 4-stroke multi cylinder engines that is very simple, so reliable, of easy implementation and which maximizes the stratification of the flue gases in the combustion chamber. Moreover, the burned gases retain or even increase, according to the invention, their temperature which is favorable to self-combustion.
  • the subject of the present invention is a combustion process controlled self-ignition of a four-stroke engine comprising several cylinders each having at least one inlet port and at least one exhaust port, ports and control means of the closure being conventional, ie according to the knowledge of the skilled person.
  • the invention can be applied to injection engines direct (FDI) or indirect.
  • the method consists during operation in partial load, to be transferred via an appropriate transfer means of the gases exhaust from a cylinder, usually in phase exhaust, to another cylinder, usually in phase intake.
  • the exhaust gases are driven via a valve specific device placed after the exhaust means, towards the means of transfer. Thanks to a second valve, the exhaust gases transferred arrive in the intake duct, upstream of the intake means.
  • a means of admission be dedicated to the entry of the exhaust gases into the cylinder (it is necessary in this at least two means of admission) to reduce the mixing between fresh gas and flue gas.
  • the exhaust gases can also be recovered from a cylinder at the end of the relaxation phase. They can also be introduced in a another cylinder at the beginning of the compression phase.
  • the method according to the invention also consists in controlling the exhaust flow distribution between the system exhaust and the transfer means.
  • the process can consist of thermally insulating and / or heating the gases exhausted in said appropriate transfer means, in order to to further improve self-ignition.
  • catalysis means can be placed in the means of transfer.
  • the positioning of the catalyst is a compromise between a positioning close to the intake valve of the cylinder, in order to have a higher temperature of the flue gases when they enter the cylinder, or so close to the exhaust valve, to facilitate the priming of this catalyst during cold starts.
  • this catalyst has the primary function of heating the burnt gases to facilitate the controlled ignition self, in the case of cold start, it participate, from its inception, in the reduction of polluting emissions during a phase where the main catalyst of the pot is usually not fully started.
  • the means of catalysis may comprise a catalyst mass or catalyst coated walls. At this place, at full load, the catalyst does not receive the flue gases, so do not risk no early deterioration and no loss of charge additional.
  • a conduit is used. common for the transfer of exhaust gases.
  • it is used for the transfer of exhaust gases, a set of ducts connecting the specific exhaust ducts to specific intake ducts two by two.
  • the present invention further relates to a combustion engine internal 4-stroke operating in controlled self-ignition and comprising several cylinders each having at least one inlet port and at least one less an exhaust port.
  • each cylinder further comprises a specific means for the passage of exhaust gases from the escape of a cylinder, usually in the exhaust phase, to at least one other cylinder, generally in the admission phase, and associated transfer means, the transfer taking place during the partial load operation.
  • the engine further comprises a means of exhaust distribution between the exhaust system and the transfer medium, partial load.
  • the means of distribution of the exhaust gas may comprise a means valve located near the exhaust means.
  • said transfer means comprises a common conduit.
  • the means of transfer includes a set of conduits connecting the ducts and valves specific to exhaust pipes and valves specific admission two by two.
  • Figure 1 illustrates the case of a motor having four cylinders 1.
  • the invention applies in fact to all engines comprising at least two cylinders.
  • the letter A shows the admission in a cylinder, the letter E the exhaust in the same cylinder.
  • Each cylinder 1 comprises at least one inlet orifice 2 a charge.
  • the present invention preferably comprises two orifices intake (as shown in the figures). By admission of a load, here it is necessary to understand: an inlet to which is associated a valve and the conduit associated with this orifice. So equivalent, it is the same for the name mean exhaust.
  • Each cylinder further comprises an exhaust port 3 conventionally equipped with a conduit and a valve associated.
  • each cylinder 1 comprises means of Valve type 4 distribution placed in the exhaust duct, although obviously downstream of the exhaust port.
  • This valve, or device equivalent allows the flue gases leaving the exhaust port to go in a means of transfer 5.
  • the means of transfer 5 is a conduit that communicates with all conduits cylinder exhaust, as well as with all intake ducts. It is these means of distribution that make it possible to control the flow of transfer of gases between exhausts and admissions. In full load, these valves 4 close the communication towards the conduit 5.
  • Each cylinder 1 also comprises a valve 7 placed in intake, close to the intake port 2. It allows the gas burned to go from the transfer means 5 to the cylinder 1, via the distribution valve 7 and the inlet port 2. At full load, these valves 7 are preferentially closed.
  • a winnowing means 6 is arranged to proximity to the exhaust 3.
  • Appropriate control and coordinated controls the opening of each valve means 4, 6, 7, and regulates and distributes the flow of gases between the exhaust conventional and the transfer means 5.
  • exhaust gases are transferred from a cylinder generally in exhaust phase to another cylinder in general admission phase.
  • the present invention can use a standard distribution for the opening of all exhaust and intake valves. In this case, partial loads, the flue gases and the fresh gases will enter together in the cylinder in the intake phase.
  • the transfer means comprises a common conduit with accesses to all specific valves 4 and 7.
  • the transfer pipe or pipes 5 can be thermally insulated, using a ceramic 8 for example. She can also be heated by specific means 8 '. So the gases that transit through a transfer line 5 do not lose or even gain calories when they arrive in the cylinder. Self-ignition is thus improved since it is known that the temperature of the recycled gases is an important parameter, which favors self-ignition.
  • a catalyst 10 can also be used to heat the flue gases and advantageously, at the same time, reduce the level of pollutants present in the flue gases passing through the transfer means 5.
  • Figure 3 shows a variant where the exhaust does not include than an orifice. It is clear that the means of admission, as exhaust, are not limited to a double exhaust and a double admission.
  • the present invention has the advantage of not having need specific transfer ports, since it uses ducts conventional intake and exhaust four-stroke engine considered.
