Definitions

  • the present invention relates to an engine operating with steam and more precisely according to a closed circuit, usable in the field of road motor vehicles, railways, ships or even industry.
  • thermal engines that operate using different energy sources.
  • the steam engine is an external combustion engine which transforms the thermal energy of water vapor produced by one or more boilers into mechanical energy. Typically, this steam enters a cylinder and exerts a pressure which gives reciprocating movement to a piston, which can turn a wheel for example via a system of connecting rods/cranks.
  • the object of the present invention is to retain the use of the vapor of a fluid brought to high temperature / pressure in an enclosure as a primary source of energy to operate a piston with reciprocating movement, but by improving it under different aspects to make it easier to use, reliable, compact, environmentally friendly, with improved efficiency and power.
  • the exhaust pipe is connected to a turbine of a turbocharger interposed between the motorization enclosure and the depression tank/the depression box.
  • the first intake pipe is connected to a compressor of a turbocharger interposed between the depression tank/depression box and the heating enclosure/the boiler to increase the steam pressure.
  • This turbocharger draws the used steam from the vacuum tank to send it to the heating chamber to return the steam to the desired temperature.
  • the depression tank/depression box comprises a second electrical heating means connected to the battery and producing a temperature maintenance of the fluid between approximately 100° C and 120° C, preferably at approximately 110°C.
  • each inlet and outlet is equipped with a sealed non-return valve, such as a flap, a valve or a drawer, controlled mechanically and/or by an electronic control module and preventing the return of vaporized fluid to the heating chamber/boiler.
  • a sealed non-return valve such as a flap, a valve or a drawer
  • each outlet is equipped with a sealed non-return valve, such as a flap, a valve or a drawer, controlled mechanically and/or by an electronic control module and preventing the return of the vaporized fluid to the motorization enclosure.
  • a sealed non-return valve such as a flap, a valve or a drawer

  • the cylinder capacity of the motorization enclosure is between approximately 1000 and 2000 cm 3 , preferably between approximately 1200 and 1600 cm 3 , the cylinder capacity may vary depending on the final use and will of course be different depending on the it is a pump, a car, an industrial plant or a locomotive.
  • FIG. 1 there figure 1 is a schematic view of the engine according to the present invention and its mode of operation.
  • FIG. 1 is therefore a block diagram illustrating a so-called self-energetic engine M operating on steam in accordance with the present invention.
  • This motor M comprises a part using a fluid, for example water or preferably a fatty hydrocarbon such as hexane, vaporizable under high pressure using heating means, and an electrical part serving both as a source of energy for the heating means and for accumulating electrical energy then returning the latter to said means of heating.
  • a fluid for example water or preferably a fatty hydrocarbon such as hexane, vaporizable under high pressure using heating means, and an electrical part serving both as a source of energy for the heating means and for accumulating electrical energy then returning the latter to said means of heating.
  • the engine M comprises at least one heating enclosure 10 (or boiler) containing a fluid F and enclosing a first heating means 12 intended to bring said fluid F to the vapor state.
  • the first heating means 12 comprises for example in the present case a series of parallel tubes surrounded by electrical resistances inside which the fluid F circulates to heat it or reheat it instantly, or else a series of parallel heating plates very close together and between which the fluid F circulates to be heated or reheated. Whatever its structure, this heating means 12 is supplied with electrical energy by a battery 120, for example 12 Volts.
  • the heating enclosure 10 communicates upstream with a reservoir 20 of vaporized fluid, called a depression tank or depression box, using a first pipe 30 making it possible to transport the fluid F from the depression reservoir 20 / depression box towards said heating enclosure 10.
  • the vacuum tank 20 comprises a second electric heating means 22 also connected to the battery 120 and producing a temperature maintenance of the fluid F between approximately 100° C and 120° C, preferably at approximately 110° C.
  • the heating enclosure 10 also communicates, downstream, with a high-pressure steam engine enclosure 40 using a second inlet pipe 50 making it possible to transport the vaporized fluid from the heating enclosure 10 to said motorization enclosure 40.
  • the first intake pipe 30 is connected to a compressor 90 of a turbocharger interposed between the vacuum tank 20 and the heating enclosure 10 to increase the pressure of the steam generated before being reheated in said heating enclosure 10 .
  • the motorization enclosure 40 contains at least one double-acting piston 60 moving (arrows T1 and T2) in an alternating and sealed manner.
  • This piston 60 comprises a rod 62 and a head 64 on either side of which are defined a first compression chamber C1 and a second compression chamber C2.
  • the first compression chamber C1 is connected on the one hand to a first inlet 52 of vaporized fluid communicating with the second intake pipe 50 and on the other hand to a first outlet 55 of vaporized fluid.
  • the second compression chamber C2 is connected on the one hand to a second inlet 54 of vaporized fluid also communicating with the second intake pipe 50 and on the other hand to a second outlet 57 of vaporized fluid.
  • the cylinder capacity of the motorization enclosure 40 is, for example for a standard car, between approximately 1000 and 2000 cm 3 , preferably between approximately 1200 and 1600 cm 3 .
  • the fluid outlets 55 and 57 join in a third common exhaust pipe 70 which ends in the depression tank 20 using a fourth pipe 80.
  • the third exhaust pipe 70 is also connected to a compressor 100 of the turbocharger interposed between the motorization enclosure 40 and the depression tank 20.
  • the first inlet 52 of vaporized fluid is equipped with a sealed non-return valve 72, such as a flap, a valve or a drawer, controlled mechanically and/or by an electronic control module and preventing the return of the vaporized fluid towards the heating enclosure 10.
  • a sealed non-return valve 72 such as a flap, a valve or a drawer
  • the second inlet 54 of vaporized fluid is equipped with a sealed non-return valve 74, such as a flap, a valve or a drawer, controlled mechanically and/or by an electronic control module and preventing the return of the fluid vaporized towards the heating enclosure 10.
  • a sealed non-return valve 74 such as a flap, a valve or a drawer
  • the first fluid outlet 55 is equipped with a sealed non-return valve 75, such as a flap, a valve or a drawer, controlled mechanically and/or by an electronic control module and preventing the return of the fluid vaporized towards the motorization enclosure 40.
  • a sealed non-return valve 75 such as a flap, a valve or a drawer
  • the second fluid outlet 57 is equipped with a sealed non-return valve 77, such as a flap, a valve or a drawer, controlled mechanically and/or by an electronic control module and preventing the return of the fluid vaporized towards the motorization enclosure 40.
  • a sealed non-return valve 77 such as a flap, a valve or a drawer
  • the rod 61 of the piston 60 is for its part connected to a set 110 of connecting rods and cranks rotating a motor shaft 114 thanks to the reciprocating linear movement of said piston 60 and the rotary movement of the connecting rod/crank assembly 110.
  • the heating enclosure 10 with its internal heating means 12, the motorization enclosure 40, the depression tank 20 with its internal heating means 22 and the first, second, third and fourth pipes 30, 50, 70 and 80 for transporting vaporized fluid form a closed sealed circuit containing between approximately 20 and 30 dm 3 of fluid F circulating in a loop. Due to this closed circuit and the tightness of these enclosures and the various pipes, no loss of fluid is possible.
  • the production of the engine parts can be made of non-ferrous metal or synthetic material since the operating temperature will only be 100 to 150° C. However, for higher performance where the temperature can exceed 200° C, the choice of materials will be of significant importance, particularly to reduce thermal losses. This choice will also depend on the steam pressure, linked to this temperature.
  • a characteristic making the invention special consists in that the first heating means 12 of the heating enclosure 10 is connected to a power supply battery 120.
  • This battery 120 is therefore considered as a secondary source of a power point. view of the operation of the motor M because it is the fluid vapor which causes the reciprocating movement of the piston 60 and the rotation of the motor shaft 114, and not directly the electricity produced.
  • the motor shaft 114 is also connected to an alternator 118 via, for example, a belt 116.
  • This alternator 118 allows, during the rotation of the motor shaft 114, to recharge the battery 120 with electrical energy during the operation of the motor M.
  • the operation of the motor M according to the present invention is as follows.
  • the heating enclosure 10 the depression tank 20 is empty or almost empty
  • the engine (M) is at rest, the piston 60 being in a first position inside the chambers C1 and C2 of the motorization enclosure 40, and the different valves 72, 74, 75 and 77 allow the admission of fluid vapor under high pressure through one or other of inlets 52 or 54.
  • the heating body 12 causes instantaneous vapor of the fluid F in the heating enclosure 10, at the desired temperature and pressure.
  • the piston 60 in its back-and-forth movement caused by the simultaneous pressure of the steam on either side of the head 64 in alternately each of the chambers C1 then C2 (the volume of which therefore changes constantly, when the volume of one increases, the volume of the other decreases in the same proportions, and vice versa), produces, via the connecting rod/crank assembly, a rotary movement of the motor shaft 114 (power take-off) .
  • the hot gases are expelled under high pressure with each reciprocating movement of the piston 60 by the isothermal pipes 55 and 57 which join in the third pipe 70 to activate the turbine 100 driving the turbocharger before arriving in the vacuum tank 20 where the vaporized fluid F is kept in a gaseous state using electrical resistances 22.
  • a defined quantity of gases contained in the vacuum tank 20 is sucked in by the compressor 90 of the turbocharger whose rotation shaft has a variator speed according to the desired pressure.
  • These gases are then sent under pressure, via the first pipe isothermal 30, in the heating enclosure 10 containing the heating body 12 to be reheated to the desired temperature and pressure, before being sent back into the motorization enclosure 40 to act on the piston 60, and so on, which forms a sealed closed circuit rotating in a loop.
  • the alternator 118 is driven by the belt 116 connected to the motor shaft 114 to permanently recharge the battery 120.
  • the aim of this system is to permanently preserve this steam by heating it more or less by the instantaneous steam boiler 10, typically to a temperature of around 100 to 120 ° .
  • the battery 120 it initially heats a small quantity of fluid F, but as soon as the motorization enclosure 40 operates, it only maintains the temperature slightly lower than that in the motor M. During its journey, the vapor must not become liquid again, but must simply cool slightly in the vacuum tank 20 before being recompressed by the compressor 90 of the turbocharger. The battery 120 is therefore no more stressed than in a gasoline engine where it ensures ignition.
  • the number of motorization enclosures and/or pistons can be increased according to the desired power, with a common battery/alternator or for each motorization enclosure.
