The The invention relates to the applied technique and the Method for producing the compressed gas during operation, at the after the expansion of the prestressed compressed gas in the Cylinders remaining residual gas derived as exhaust controlled, over Conveyed compressor in storage tanks and also over the compressed gas generated by means of an auxiliary unit enriched in such a way that will eventually complement that in the storage tanks and prestressed compressed gas the engine again for the drive can be supplied, which pollutant emissions by pressurized gas operation by this system can be reduced.

Out The prior art, various applications are known, the Inventions describe the subject of hybrid or compressed gas engines have and have features of the filed application.

In the DE 199 23 451 An emission-free hybrid engine is described which comprises an electric motor, a battery for driving the electric motor, a compressed air motor, a compressed air tank for driving the compressed air motor, a generator for generating electric energy and a decision and control device for controlling various operating conditions.

The The invention presented here gives the impression of a "perpetuum Mobiles ", in which constantly new energy is gained, what but not possible according to the laws of physics is. If this system is operated under load, it can be assumed that the efficiency for driving a vehicle against Zero goes.

From the DE 43 42 950 For example, a hybrid engine is known which first compresses and enriches a fluid in a multi-stage process and directs the high pressure, hot exhaust gases via a rotary piston set which is set in motion to work. For this purpose, depending on the variant embodiment, the hybrid engine consists of at least one combined compressor rotary piston set and engine rotary piston set or autonomously arranged rotary piston sets, which are arranged within one volume, with the valves, supply and disposal lines, auxiliary units and operating materials required depending on the variant.

Of the Hybrid engine described here works by methods in which the drive energy is obtained from a strongly heated fluid, which leads to corresponding material loads and in the Material selection must be taken into account and in shape of elaborate, heavy and expensive constructions Precipitation finds. When registering, the drive energy produced in a "cold" process that becomes material not stressed by heat and the volume for the engine can suitably around the components cooling technology and thus the total weight will be reduced.

The DE 10 2004 005 349 discloses a hybrid engine composed of an electric motor and an internal combustion engine connected via a planetary gear. Between this planetary gear and an automatic transmission, a clutch is connected and the electric motor and the internal combustion engine are connected via a sun gear with a planet carrier.

at The presented technique is in particular a compact one Hybrid engine consisting of electric motor and internal combustion engine, which are connected via a specific planetary gear to develop, the electric motor u. a. for starting the internal combustion engine is used. In the embodiments and the claims to the application shows that this hybrid engine no features to the hybrid engine in the new application has.

In the DE 103 23 534 a pressure gas engine for vehicles is presented, which is operated by liquid air and commercial fuel. The liquid air is transferred from tanks into a pressure chamber where it is evaporated and heated by the combustion of the fuel. An electronic control and regulating device is used to adapt the operating pressure to the respective operating situation.

Unlike the new application will be at the DE 103 23 534 worked with liquefied petroleum gas, that is first prepared for the pressure level required for a sufficient operating pressure via an immediate combustion process and then forwarded to a two-stage rotary valve motor. In the new application, however, is located in tanks, biased pressurized gas via a control device, which is not the subject of this invention, passed into the engine and residual gas and pressure gas losses via an auxiliary unit in conjunction with control devices processed or balanced and stored in tanks, so as Drive motor can be made available again.

The here presented inventions thus show techniques in which the idea was implemented, an alternative to the internal combustion engine to create, or at least in combination with, this in the first place Line to reduce pollutant emissions and fossil fuel consumption To reduce fuels or to make the drive more effective. The inventions in this case offer practicable Individual solutions for subareas of the task complex the aforementioned type of this new application, however So far, no solution concept is presented that is the functional one Operation of a compressed gas engine in combination with an auxiliary unit open and controls the derived from the system residual gases collects, compacts, directs into storage tanks and the system finally feeding again, the engine without a starter in the traditional sense put into operation can be.

It is therefore an object of the invention, from the prior art a Compressed gas hybrid engine to develop, consisting of the modules engine, control device Compressed gas, tank system, auxiliary unit, starter and control device is constructed and the required for the operation Compressed gas from the resulting during the engine power stroke and controlled derived residual gas in combination with an auxiliary unit to generate compressed gas wins.

• – das während des Betriebs anfallende Restgas nicht nach außen abgeleitet wird, sondern im System verbleibt und wieder angereichert wird,
• – über ein Hilfsaggregat Druckgasverluste ausgeglichen werden und das System sich somit selbst versorgt,
• – Schadstoffemissionen verringert werden,
• – der Verbrauch fossiler Brennstoffe verringert wird und,
• – durch den Wegfall von herkömmlichen Baugruppen eines Verbrennungsmotors eine Gewichtsersparnis erzielt wird.

The advantages achieved by the invention are in particular that

• - Compressed gas losses are compensated via an auxiliary unit and the system thus self-sufficient,
• - Pollutant emissions are reduced,
• - the consumption of fossil fuels is reduced and,
• - By eliminating conventional components of an internal combustion engine, a weight saving is achieved.

The The above-described problem is solved by the in the claims listed features and clarified The technical implementation is the following variant described by way of example.

Of the Engine, according to a normal internal combustion engine, consisting from the engine housing with cylinders, pistons and crankshaft, is supplied with compressed air via two storage tanks, whereby the compressed gas passed through a rotary valve to the cylinders becomes.

In this representation assumes for Tank A that stored herein a biased amount of compressed gas, the enough to start and drive the motor.

Of the Start of the engine is done mechanically via a Hand switch such that with operation of the manual switch a test and control unit is activated, the over a measuring line determines the pressure in the tanks by means of measuring probes and then activates a control valve which is the tank associated with the higher pressure, in this case tank A. is. As soon as the valve is opened, it flows prestressed compressed gas from tank A via the in a compressed gas line integrated control valve to the rotary valve, the subject of a further registration is.

This Rotary valve, which forms the engine block cover, does not regulate only the supply of compressed gas to the respective cylinders of the engine but takes over also the discharge of the residual gas from the system. Exists for this the rotary valve from an outer housing, with a inner, rotatably mounted hollow tube, referred to as rotor, that via a drive belt with the crankshaft of the engine connected and running in sync with this. The outer housing is pierced at defined points, over which the compressed gas is passed into the system according to the invention. Of the internal rotor also has specific holes that with a compressed gas line are interconnected, wherein the bores during a certain power stroke of the engine with the Inlet / outlet opening to one of the cylinders and a compressed gas supply line correspond and so the inflow of biased Compressed gas in a cylinder, in a position of the piston in the area of the OT, allow and while expanding the prestressed Pressurized gas inside the cylinder push the piston towards UT, so that the crankshaft of the engine is set in motion.

Farther the wall of the rotor is milled out at defined areas in such a way that during the further rotation of the rotor these zones, the are each assigned to a cylinder, after completion of the active phase a cylinder above the inlet / outlet of the Cylinders are led past, at a time when the piston is in the area of the UT. With further rotation of the Crankshaft, the piston moves from the position UT in the direction OT and promotes that after the expansion of the pre-stressed Compressed gas still in the cylinder residual gas from the cylinder beyond the inlet / outlet of the cylinder in the interior of the rotor, which serves as an exhaust chamber.

About a compressor, which is positioned on the exhaust side of the rotary valve and automatically switches on when the compressed gas engine starts, the residual air from the exhaust air space of the rotor is first aspirated and then passed through a control valve to the tank B and compressed, which serves as a storage tank during this phase of operation, until the pressure in tank A, which is used in this phase as a working tank, has not fallen below a defined minimum value. If the working pressure in tank A falls below the predetermined minimum value, the pressure gas supply for the engine is switched from tank A to tank B, which now assumes the role of the working tank. Parallel to this, the control valve assigned to the compressor in the area of the exhaust air side now switches over to the filling of the tank A, which now takes on the role of the storage tank. The control valve also ensures that the corresponding tank systems are filled with compressed gas only when they do not initiate a biased compressed gas in the rotary valve system or deliver it to the engine.

With Decrease of the pressure below a defined minimum value in one the two tank systems, the connection of an auxiliary unit, depending on the design variant of a small combustion engine or an electric motor can exist, which in the functional context with a combined aggregate that functions pump and clutch fulfilled, stands.

So long the auxiliary unit is not working in own mode is running this synchronous with the drive shaft of the engine, without losing its his intended function, filling the tank A or B with Compressed gas, to meet.

about the combination unit clutch / pump is activated when the auxiliary unit is activated whose shaft is separated from the drive shaft of the compressed gas engine, since the auxiliary unit in independent working with a higher number of revolutions than the crankshaft of the compressed gas engine. The tracking characteristic of the shaft of the auxiliary unit pursues the purpose that this wave is at least the same number of revolutions as the shaft of the compressed gas engine has and thus when connected the auxiliary unit is pre-accelerated and thus an optimized Has startup behavior.

To the start of the auxiliary unit this drives the combi unit Coupling / pump and it is in this exemplary operation on the arranged in the supply air line of the tank A and this Tank associated control valve switched so that over this supply air line of the tank A with generated by the combi unit Compressed air filled until reaching the specified maximum pressure becomes. When the threshold is exceeded, an electronic Shutdown command generated, which shuts off the auxiliary unit. The now "empty" trailing wave of the auxiliary unit is over Synchronous rings in the combi unit only then back to the shaft of the compressed gas engine switched on, if there is a synchronism in both shafts.

Of the above described process applies mutatis mutandis for the filling of the second tank, the corresponding to the system with its own control device with valves and Supply air lines is coupled. About the corresponding Systems will ensure that there is always sufficient Quantity of pre-pressurized gas available to the engine can be made.

Should while the engine is operating in the area of the exhaust system an overpressure / back pressure occur, the functional sequence of the Pressurized gas engine would interfere with this pressure a pressure relief valve arranged in the compressor section derived to the outside and u. a. for cleaning a filter system which is the subject of another application and in which Use of an internal combustion engine as an auxiliary unit for cleaning the exhaust gases is used.

A advantageous embodiment of the invention is in the claims 2 and the following, it being understood that the above described and below to be explained specifications not only in the specified combination, but also in other combinations or as an independent execution object are usable without the actual scope of the featured To leave invention.

embodiments The invention is illustrated in the drawings and will be described below described in more detail.

It demonstrate:

1 schematic representation of the hybrid engine with auxiliary unit

2 schematic representation according to 1 with additional emission control

3 schematic representation of the main modules to explain the summary

It follows the explanation of the invention with reference to the drawings after construction and possibly also after operation of the illustrated invention.

1 shows the schematic representation of a compressed gas hybrid engine 1 consisting of engine 2 , Rotary valve 3 , Cylinder 4 , Exhaust duct 5 , Compressor 6 , Control valve compressor 7 , Tank Supply 8th , Check valve exhaust air 10 , Tank A 11 , Filler neck 12 , Tank holder 13 , Quick coupling 14 , Compressed gas line 15 , Control valve supply air 16 , Supply line rotary valve 17 , Check valve 18 , Supply air tank A 19 , Check valve supply air 20 , Auxiliary unit 21 , Shaft auxiliary unit 22 , Combined unit clutch / pump 23 and the components of the second tank with check valve 24 , Control valve supply air 25 and tank B 26 , as well as the start and control device with manual switch 31 , Test and control unit 32 , Measurement line 33 , Measuring probe 34 , Control line 35 , Control line exhaust air 36 and proportional valve 37 ,

Shown is the embodiment of a compressed gas hybrid engine 1 whose engine 2 with compressed gas from two tanks, tank A 11 and tank B 26 , is operated. The tanks, fastened with brackets 13 , are with the compressed gas lines via quick couplings 14 connected, which allows a quick replacement of the entire tank, and are external with compressed gas via a filler neck when needed 12 fillable.

Above the engine 2 , a 5-cylinder inline engine, is the rotary valve 3 , which is the subject of another application, put on, with the schematically indicated cylinders 4 ,

To start the engine is via a manual switch 31 the test and control unit 32 This first activates the pressure in the tanks 11 / 26 determined by the data of the probes 34 over the measuring line 33 be read out. Depending on the evaluation is now the control valve 16 / 24 activated, its assigned tank 11 / 26 has the higher pressure.

In this exemplary description, assume that the measurement in Tank A 11 the higher pressure could be determined, leaving the test and control unit 32 over the control line 35 the control valve supply air 16 switches, which the tank A 11 is assigned directly. This causes out of the tank A 11 Compressed gas via the compressed gas line 15 , the supply rotary valve 17 and a proportional valve 37 to the rotary valve 3 can flow.

The proportional valve 37 has the task, the volume flow of the rotary valve 3 to regulate incoming compressed gas and thus the amount and thus the converted energy or the engine 2 depending on how much accelerated and thus the passage in the proportional valve 37 is controlled, so a correspondingly large or small amount of compressed gas to the rotary valve 3 rush through.

The proportional valve 37 Downstream is the rotary valve 3 , which regulates the distribution of the compressed air to the cylinders and the discharge of the residual air and in the housing there is a movably mounted, so-called rotor, which controls the direct Druckgaszu- and-derivative and synchronously with the crankshaft of the engine 2 running.

The compressed gas supply lines inside the rotary valve 3 are each in the cylinder in the filling position, the piston is in the phase of downward movement from the position OT in the direction of UT. By the inflowing into the cylinder and here now expanding compressed gas, the piston is pressed in the direction of UT and thereby the crankshaft of the engine 2 driven. The residual gas in the cylinder after the expansion becomes with the upward movement of the piston in the direction of TDC in the exhaust air space of the rotary valve 2 from where it comes from the compressor 6 , which automatically switches on when starting the engine, via the exhaust air line 5 is sucked off.

As long as the pressure in the tank A 11 has not fallen below a defined minimum value and in this phase of operation as a so-called working tank the pressurized gas for the engine 2 returns, that is from the compressor 6 exhausted residual gas via the control valve 7 for filling the tank B 26 , which serves as a storage tank in this phase, derived and condensed there.

Determines the test and control unit 32 in the tank A 11 a gas pressure below the defined minimum value, becomes the control valve 16 locked and on the control valve 25 switched so that now the compressed gas from tank B 26 to the rotary valve flows and the engine 2 supplied with compressed gas.

Parallel to this is via the "control line exhaust air" 36 the "control valve compressor" 7 switched and the over the exhaust duct 5 and the compressor 6 flowing residual gases to tank A 11 , which is now used in this phase of operation as a storage tank, directed and condensed there constantly.

When the pressure in tank A drops 11 below the minimum value, in addition to supplementing the pressure gas required for operation, the auxiliary unit 21 started that over a wave 22 a combi unit 23 with the functions clutch / pump drives. In the conveying mode, the pump of the combi unit is used 23 Compressed air generated via the supply air line 19 and the compressed gas line 15 in this exemplary illustration in the tank A 11 is promoted until reaching the maximum pressure, whereupon the auxiliary unit 21 and thus the compressed air generation is stopped again.

In idle mode, when the pump does not deliver pressurized gas to the tanks 11 / 26 is promoted, the wave is running 22 of the auxiliary unit 21 synchronous to the shaft of the motor 2 with, whereby upon connection of the auxiliary unit 21 the wave 22 already pre-accelerated and the startup behavior of the unit 21 is optimized. In-house operation becomes the wave 22 of the auxiliary unit 21 from the shaft of the engine 2 uncoupled, as it is with a higher number of revolutions as the engine is working. When switching off the unit 21 becomes the wave 22 via synchronizer rings back to the engine 2 coupled as soon as both waves have the same rotational speed.

Analogously, the described pressure gas generation also applies to the tank A with 11 corresponding tank B 26 , which is then filled with compressed gas when returned to tank A. 11 is switched in the function as a working tank.

2 shows the schematic, expanded representation of a compressed gas hybrid engine after 1 consisting of engine 2 , Rotary valve 3 , Cylinder 4 , Exhaust duct 5 , Compressor 6 , Control valve compressor 7 , Tank Supply 8th , Check valve exhaust air 10 , Tank A 11 , Filler neck 12 , Tank holder 13 , Quick coupling 14 , Compressed gas line 15 , Control valve supply air 16 , Supply line rotary valve 17 , Check valve 18 , Supply air line tank A 19 , Check valve supply air 20 , Auxiliary unit 21 , Shaft auxiliary unit 22 , Combined unit clutch / pump 23 and the components of the second tank with check valve 24 , Control valve supply air 25 and tank B 26 , Exhaust pipe 27 , Exhaust gas cleaner 28 , Pressure relief valve 29 and overpressure line 30 , as well as the start and control device with manual switch 31 , Test and control unit 32 , Measurement line 33 , Measuring probe 34 , Control line 35 , Control line exhaust air 36 and proportional valve 37 ,

In this embodiment, the compressed gas engine to the functional parts pressure relief valve 27 and exhaust gas cleaner 28 , which represents a standalone application, has been expanded.

The functional sequence is the same as under 1 explained, as an auxiliary unit 21 a small internal combustion engine is used, in which it is necessary to filter out the resulting in operation in the exhaust gases pollutants. For this purpose, the invention, the assembly exhaust gas cleaner 28 on which the over the exhaust pipe 27 during operation of the auxiliary unit 21 The exhaust gas is received in the exhaust gas cleaner in the variant "internal combustion engine" 28 passed through the filter system via an eccentric displacer to retain the particulate matter without creating back pressure or back pressure in the exhaust system. To clean the filter system, a defined amount of compressed gas is forced through the filter elements at periodic intervals in order to first detach the fine dust particles from the filter structure and then to collect the released particles in an exchangeable collecting container. The required pressure gas is via appropriate pressure relief valves 29 that are in the tank feeders 8th in the exhaust part of the compressed gas engine 2 are integrated, controlled branches and over the pressure line 30 the exhaust gas cleaner 28 supplied there to be used as described above for cleaning the filter elements.
