Definitions

  • the invention relates to an arrangement comprising a reciprocating engine, which is designed for combustion-free operation, and a vacuum chamber in which a reduced air pressure can be generated compared to the atmosphere surrounding the reciprocating engine.
  • the invention further relates to a method for operating such an arrangement and the use of the arrangement for driving a mechanical machine and/or for generating electrical current.
  • the EP 3 249 155 A1 (Benkendil ) describes, for example, an air motor that does not convert heat into mechanical work like a conventional heat engine, but works through the effect of negative pressure.
  • a cylinder is used, which is closed at both ends and is divided into two chambers on the inside by a movable piston.
  • Each of the two chambers is provided with an inlet valve and an outlet valve, whereby each chamber can be connected to a vacuum generator via its outlet valve and to the ambient air via its inlet valve.
  • the outlet valve of one chamber is open, the inlet valve of that chamber is closed, while in the other chamber the inlet valve is open and the outlet valve is closed.
  • the piston can be moved back and forth in the cylinder.
  • a push rod attached to the piston and led out of the cylinder Via a push rod attached to the piston and led out of the cylinder, its translational movement can be converted into a rotational movement by means of a corresponding mechanism, so that a generator can be operated, for example.
  • the venturi tube can be installed in a watercourse, in the area of a weir or at the outlet of a dam.
  • the object of the invention is therefore to provide improved solutions which make it possible to use negative pressure as a form of energy.
  • devices based on power machines are to be provided, which perform mechanical work by using negative pressure, which in turn can be converted into other forms of energy if necessary.
  • a substantially constant pressure means in particular that during operation the pressure in the area of the piston facing away from the cylinder head changes by no more than 50 mbar, in particular by no more than 10 mbar.
  • the moving parts of the reciprocating engine are optimally protected against damage and weather influences and the pressure ratio in this area can be controlled as best as possible.
  • inlet valve and the outlet valve are two separate valves, with the outlet valve being designed exclusively to remove air from the working space, while the inlet valve is designed exclusively to feed air into the working space. Due to this separation, the air supply and exhaust is controlled extremely precisely. If the air supply and the air discharge take place via the same inlet or outlet, the efficiency decreases significantly.
  • a vacuum chamber in the arrangement according to the invention also ensures a substantially constant vacuum during operation of the reciprocating engine, specifically over a wide range independently of the speed. This cannot be achieved by simply sucking the air out of the working area with a fan or the like.
  • the vacuum chamber has a volume that is larger than the cubic capacity of the reciprocating engine.
  • the volume of the vacuum chamber corresponds to at least ten times, in particular at least a hundred times, in particular at least a thousand times, the cubic capacity of the reciprocating engine.
  • the displacement of the reciprocating engine defines the volume that is displaced by the stroke of all pistons.
  • the functional interaction of the elements of the inventive arrangement is a surprisingly advantageous and efficient use of negative pressure and conversion into mechanical work.
  • the individual elements of the arrangement according to the invention interact synergistically.
  • the reciprocating piston engines used according to the invention can be realized by converting conventional internal combustion engines, e.g. gasoline engines or diesel engines. Depending on the engine type, it is sufficient to adjust the valve control, for example, so that the engine can be operated with a vacuum.
  • the arrangement according to the invention can thus be implemented in a relatively simple and cost-effective manner.
  • the reciprocating engine is therefore an internal combustion engine with modified valve control.
  • the reciprocating engine has at least two cylinders, in particular four, five, six, eight, ten or twelve cylinders.
  • the advantages according to the invention thus come into play to a particularly large extent. In principle, however, it is also possible to provide a reciprocating piston engine with a single cylinder.
  • the reciprocating engine is a V-engine, a radial engine, or an in-line engine.
  • V-engine a V-engine
  • radial engine a radial engine
  • in-line engine a motor that uses the reciprocating engine to generate a V-engine to generate a V-line.
  • other motor geometries are also possible.
  • the valve control is implemented in particular via at least one, for example via two, camshaft(s) and/or cam disk(s) coupled to the crankshaft.
  • the crankshaft is coupled purely mechanically to the at least one camshaft and/or cam disk.
  • the inlet and outlet valve is preferably opened and closed via tappets, rocker arms and/or rocker arms interacting with the at least one camshaft and/or cam disk. This enables the valves to be opened and closed particularly precisely and quickly, which is particularly advantageous for operating the reciprocating piston engine with negative pressure.
  • the coupling is implemented in particular via a timing chain or a toothed belt.
  • valve control can also be implemented differently.
  • valve control is a pneumatic, hydraulic and/or electromechanical valve control.
  • the at least one camshaft and/or cam disk is coupled to the crankshaft in particular with a gear ratio of 2:1, so that during operation the at least one camshaft and/or cam disk has half the speed of the crankshaft. This allows the valves to be opened and closed precisely. However, other transmission ratios can also be implemented.
  • an engine block, the piston, the connecting rod, the crankshaft, the at least one camshaft and/or the crankcase of the reciprocating engine in particular the entire mechanical structure of the reciprocating engine, consists of plastic, ceramic and/or a composite material.
  • the weight of the reciprocating engine can thereby be reduced, manufacture can be simplified and/or the costs for manufacture and spare parts can be lowered. Since the operation of the reciprocating engine generates little frictional heat, the reciprocating engine hardly heats up. Cooling is not required. It is therefore possible to manufacture the engine or components thereof from less heat-resistant and cheaper materials than conventional internal combustion engines. Another advantage of the materials mentioned is that they can be produced with almost any shape and structure, e.g. using additive manufacturing processes such as 3D printing, so that specially designed motor shapes can also be realized.
  • the engine block, the piston, the connecting rod, the crankshaft, the at least one camshaft and/or the crankcase of the reciprocating engine, in particular the entire mechanical structure of the reciprocating engine are made of metal. This means that particularly robust reciprocating piston engines can be implemented.
  • the valve control is designed in particular in such a way that when the maximum stroke height of the piston in at least one cylinder is reached, the outlet valve is opened and the inlet valve is closed, so that the air pressure in the working chamber is reduced and when the minimum stroke height of the piston is reached in at least one cylinder, the inlet valve is reduced is opened so that the air pressure in the working space is increased. This takes place in particular in regular cycles during operation of the reciprocating engine.
  • the maximum stroke of the piston is reached when the working space in the cylinder has the maximum volume, while the minimum stroke of the piston is reached when the working space in the cylinder has the minimum volume.
  • a cycle is a complete movement of the piston from one dead center to the other dead center.
  • a cycle takes place in particular during half a revolution of the crankshaft. Both strokes occur together during one complete revolution of the crankshaft.
  • the first time section and the second time section in the second cycle correspond in particular to 40-60% each, in particular 50% each, of the duration of the entire second cycle.
  • the first and second time segments thus each correspond to half a clock.
  • the two clocks are executed one after the other during operation, in particular in a continuous process.
  • valve controls described above have proven to be particularly preferred.
  • crankshaft and the valve control are designed in such a way that the pistons in the respective cylinders are moved at least partially out of phase during operation. This is analogous to conventional combustion engines.
  • the negative pressure chamber is in particular connected in a fluid-conducting manner to a vacuum generating device, in particular a vacuum pump, so that the negative pressure chamber can be or is evacuated by the vacuum generating device in a vibration-free manner.
  • the arrangement according to the invention can be operated by completely different vacuum generation devices and can therefore be used extremely flexibly.
  • the vacuum generating device includes a Venturi tube.
  • a Venturi tube can be used as a pump that is simple in design and has no moving parts. Venturi tubes are correspondingly robust, low-maintenance and versatile.
  • the Venturi tube is placed in a watercourse, for example in the area of a weir or at the outlet of a dam. As a result, water power can be converted into mechanical energy with the arrangement according to the invention and, if necessary, further into electrical energy, e.g. via a generator.
  • the vacuum generating device comprises an electrically operated vacuum pump, in particular a rotary vane pump.
  • the electrically operated vacuum pump can be present as an additional or sole vacuum generation device. This makes it possible, for example, to compensate for fluctuations in other vacuum generation devices.
  • the arrangement according to the invention can be operated entirely by electrical energy, e.g. by solar energy or excess energy from the electricity network.
  • vacuum generation devices such as mechanically operated pumps are also conceivable, which can be driven by wind energy, for example.
  • the vacuum generating device also includes the electrically operated vacuum pump a vacuum booster, which is connected between the vacuum chamber and the electrically operated vacuum pump.
  • the vacuum booster is operated electrically.
  • Vacuum boosters increase the pumping speed and the ultimate pressure of vacuum pumps. They increase the performance of vacuum systems by a factor of up to ten. Vacuum boosters work according to the Roots principle: Two Roots pistons rotate synchronously within a housing. These do not touch each other or the housing. This means that no lubricants or operating fluids are required in the process chamber. During the rotation of the Roots, gas is transported between the Roots and the housing into the downstream vacuum pump.
  • the pressure in the vacuum chamber is preferably at least 0.2 bar, in particular at least 0.4 bar, in particular at least 0.7 bar, lower than the atmospheric pressure surrounding the reciprocating engine.
  • the pressure in the vacuum chamber is in the range of 0.05-0.8 bar, in particular 0.1-0.5 bar, in particular 0.1-0.3 bar. At such pressures, the arrangement according to the invention works particularly effectively. In special constellations, however, other pressure conditions are also possible.
  • the reciprocating engine has a turbocharger, the turbocharger being driven by the air flowing out of the outlet valve and compressing the ambient air supplied via the inlet valve.
  • a turbocharger consists of a turbine that uses the energy from the expelled air and drives a compressor that compresses the ambient air that is supplied. The air supply is thus increased in order to achieve faster volume filling.
  • crankcase has a crankcase ventilation, in particular an open crankcase ventilation.
  • a crankcase ventilation in particular an open crankcase ventilation.
  • This is designed in such a way that the inner volume of the crankcase and/or the area of the piston facing away from the cylinder head communicates with the surrounding atmosphere in a fluid-conducting manner.
  • a substantially constant pressure can be maintained in the area of the piston facing away from the cylinder head in a simple manner and at the same time the connecting rod and crankshaft can be protected from external influences.
  • crankshaft of the reciprocating engine is coupled to a power generator, so that power can or is generated by the work of the reciprocating engine.
  • the electricity can, for example, be used to operate external consumers and/or be temporarily stored in an electricity storage device.
  • Another aspect of the present invention relates to a method for operating an arrangement as described above, wherein negative pressure and ambient pressure are alternately applied via the inlet valve and the outlet valve in the working chamber, so that the piston in at least one cylinder is moved back and forth, so that the crankshaft is driven.
  • the outlet valve is opened and the inlet valve is closed, so that the air pressure in the working chamber is reduced and when the minimum stroke of the piston in at least one cylinder is reached, the outlet valve is closed and the inlet valve is opened , so that the air pressure in the working area is increased.
  • the two clocks are executed one after the other during operation, in particular in a continuous process.
  • the vacuum chamber is in particular continuously evacuated with a fluid-conducting connected vacuum generating device, in particular a vacuum pump.
  • a fluid-conducting connected vacuum generating device in particular a vacuum pump.

  • the pressure in the vacuum chamber is kept in the range of 0.05-0.8 bar, in particular 0.1-0.5 bar, in particular 0.1-0.3 bar.
  • the air flowing out of the outlet valve is used to drive a turbocharger, which compresses the ambient air before it is supplied via the inlet valve. This further improves the efficiency.
  • crankcase is vented during operation via a crankcase ventilation, in particular an open crankcase ventilation.
  • An additional aspect of the present invention relates to the use of an arrangement as described above for driving a mechanical machine and/or for generating electrical current.
