Definitions

  • the invention relates to a method and devices for pollution control. cyclic internal combustion engines with combustion chamber independent and at constant volume.
  • the chamber compression chamber, the combustion chamber and the expansion chamber are consisting of three separate and fully independent parts thus allowing each of the three elements to be adapted to the function which is devolved without interfering with one another, possibly equipped a trigger control system that allows the maximum expansion pressure with an angle of rotation of the crankshaft allowing a great tangential effort, further improving the yield general of this type of engine.
  • the method according to the invention makes it possible to completely eliminate these polluting gas emissions, especially in urban traffic, so that the engine requires little power.
  • the fuel injector is no longer controlled and only in this case, it is introduced into the combustion chamber, by any means -sensibly appropriate after admission to the latter of air compressed (without fuel) from the engine compressor - one small amount of additional air from an external tank in which is stored air (or any other gas) under very high pressure; this small amount of compressed air, and at room temperature will heat up in contact with the mass of hot air contained in the combustion, expand and significantly increase the prevailing pressure in the combustion chamber, to allow delivery during trigger, engine work of sufficient power to operate, for example, a vehicle in urban traffic. Adjusting the quantity additional air injected will condition the power delivered.
  • the quantity of additional air injected, the injection means, the air storage method compressed, the gas used, the means of filling the storage tank - by compressor on-board operating during decelerations and braking or in road operation, and / or at pump in specially equipped service stations or, by replacement of the bottle storage - may vary without changing the principle of the invention.
  • the invention is particularly applicable to cyclic internal combustion engines with independent combustion chamber at constant volume, especially in urban use on vehicle, as well as for any other engine application. It also applies to motors with conventional internal combustion.
  • Figures 1 and 2 show an embodiment of the method according to the invention. applied to a cyclic internal combustion engine with independent combustion chamber at constant volume where the combustion chamber 1 is supplied by a buffer capacity 2 of air compressed maintained at a substantially constant pressure, itself supplied by a compressor through a conduit 3.
  • a conduit 4, the opening and closing of which are controlled by a flap 5 connects the buffer capacity 2 to the independent combustion chamber 1 and includes an air injector fuel 6 intended to produce the air-fuel mixture substantially before it is introduced into the combustion chamber 1 where it will be ignited.
  • An expansion cylinder 7 is equipped with a main piston 8 connected by a connecting rod 9 to the crankpin of a crankshaft 10, and of a secondary opposite piston 11 whose movement is controlled here by a cam 12 - itself driven by the crankshaft 10 - so that it will accompany the main piston 8 over part of its downward stroke in order to allow the pressure at the start of expansion - as soon as the channel 14 is opened, by the flap 15, which connects the combustion in the expansion chamber 16 - in a minimum volume, with angles of rotation of the crankshaft and inclination of connecting rod which allow to obtain the average tangential stress of relaxation optimal.
  • An additional compressed air injector 22 is installed in the combustion chamber 1, and is supplied, through a pressure reducer, by a cylinder of compressed air 23 (or any other compatible gas) for storage under high pressure.
  • the combustion chamber I has just been isolated and contains a mass of hot, pure, fuel-free compressed air - the fuel injector 6 having no not been ordered -
  • the additional air injector 22 is open and introduces a small amount of additional air mass from the high pressure storage bottle 23, relaxed under a pressure slightly higher than that prevailing in the chamber combustion, to allow transfer; this additional air mass will heat up in contact with the compressed air contained in the chamber, expand and significantly increase the initial pressure to allow work to be produced when opening, figure 2, the channel 14 by relaxing in the relaxation room. Due to the excellent performance of the power unit shown, the the amount of additional air will be very small and will condition the power delivered.
  • the means for injecting additional air into the combustion chamber can vaner without changing the principle of the invention, however, an electromechanical injector such as than fuel injectors which can be managed more easily, in particular in terms of flow, by on-board electronics.
  • FIG. 3 represents a block diagram of an installation of the following method the invention on a vehicle, where the additional compressed air storage tank under high pressure 23A is equipped on the one hand with a filling opening "at the pump” 24 and also with a auxiliary filling port 25 supplied by a small on-board high pressure compressor 26 which will be put into operation by a clutch system 27 during decelerations and braking, thus providing an excellent engine brake to the vehicle, and also when high power road operation.
  • This provision having the advantage of increasing considerably the autonomy in depolluted operation.
