- a supply line for supplying a gas mixture to the combustion chamber, the gas mixture comprising gasified organic compounds (that is, a gaseous portion of the volatile organic compounds from the gasification tank) and at least a portion of the hydrogen gas and oxygen gas produced in the electrolysis chamber.
- the supply line and the gasification tank are thus arranged so that during operation of the vehicle drive system, a gas mixture, as defined above, is passed to the combustion chamber.
- the method of the abovementioned type is developed according to the invention in that volatile organic compounds, in particular methanol or ethanol, are gasified in a gasification tank and in that a gas mixture which comprises gasified organic compounds and at least part of the hydrogen gas and oxygen gas produced in the electrolysis chamber the combustion chamber is passed.
- hydrogen gas and oxygen gas which are produced by electrolysis, are passed into the combustion chamber only together with gaseous volatile organic compounds, ie in particular together with methanol and / or ethanol converted into gaseous form.
- gaseous volatile organic compounds ie in particular together with methanol and / or ethanol converted into gaseous form.
- the volatile organic compounds may, in principle, be a specific organic compound or a mixture of different organic compounds.
- Volatile organic compounds may be taken to mean all organic compounds which are predominantly gaseous at room temperature and / or have a boiling range below 100 ° C. or below 200 ° have G or 300 ° C.
- organic compounds may be particularly hydrocarbons, and / or any compounds that predominantly the best of hydrogen and carbon atoms "hen.
- examples of such organic compounds are Alkanoie (such as methanol and ethanol), alkanes (such as methane or ethane ).
- Under the gasification tank can in principle be understood any container in which volatile organic compounds are added. These can at least partially pass from liquid to gaseous form there.
- the vacuum pump and the gasification tank are arranged so that the hydrogen gas and the oxygen gas are at least partially carried by the vacuum pump from the electrolysis chamber into the gasification tank. The gas mixture is then produced in the gasification tank.
- the supply line can therefore start at the gasification tank and from there transport the gas mixture in the direction of the combustion chamber.
- the gasification tank can therefore comprise an inlet which is connected to the electrolysis chamber, an outlet from which gaseous organic compounds and hydrogen and oxygen gas are discharged, and a closable filling opening for replenishing liquid organic compounds, for example, ethanol.

- the lower part in particular the lower half or the lower quarter of the gasification tank can be considered.
- the gases introduced can flow through the gasification tank in a more evenly distributed manner, which is likewise advantageous for greater gasification.
- the supply line itself can indeed run directly to the combustion chamber. In principle, it is sufficient if the supply line is connected to a line device which can guide the gas mixture to the combustion chamber. It is preferred if the supply line is connected to an air intake component of the internal combustion engine.

- the electrolysis chamber can generally be understood to mean any device which generates hydrogen gas and oxygen gas using electrical energy, that is to say in particular H 2 and O 2 .
- a starting material of the electrolysis water or a water-containing mixture can be used. It may be advantageous if the electrolysis chamber and a conduit system are formed from the electrolysis chamber to the gasification tank so that generated hydrogen gas and oxygen gas can be conveyed as an explosive gas without separation. As a result, with a comparatively simple construction, a time-exact ignition in the combustion chamber by introducing this detonating gas is possible.
- a condensate trap that is a condensate collector
- a separation between an electrolyte and the generated hydrogen / oxygen mixture can take place.
- the electrolyte condenses in the condensate trap and can then be pumped back into the electrolysis chamber via an electrolyte circulation pump.
- the internal combustion engine is thus protected from liquid ingress by the condensate trap.
- Gaseous hydrogen and oxygen gas is sucked out of the condensate trap by the vacuum pump.
- the vacuum pump may be a pump of any type in principle. It generates a negative pressure, through which soft hydrogen gas and oxygen gas are sucked out of the electrolysis chamber.
- the vacuum pump may also consist of several pumping units. This is particularly advantageous » if generated hydrogen gas and oxygen gas are separated, so not sucked off as a detonating gas.
- the vacuum pump can also increase the efficiency of the electrolysis chamber.
- electrodes of the electrolysis chamber be surrounded by liquid electrolyte, blistering, such as gases such as generated hydrogen and oxygen gas, inhibit electrolysis and require higher temperatures.

- gas in particular hydrogen and oxygen gas
- the internal combustion engine of the vehicle drive system may be an engine formed in a manner known in principle, which generates heat energy and thus kinetic energy for driving the vehicle by combustion of a (in particular fossil) energy carrier.
- a (in particular fossil) energy carrier In this case, at least diesel, that is a diesel fuel injected.
- the exact composition of the diesel fuel may be variable in a substantially known manner.
- the vehicle drive system may also include an exhaust filter for purifying exhaust gases, such as a soot particulate filter.
- an exhaust filter for purifying exhaust gases such as a soot particulate filter.
- the cleaning of the exhaust gas filter is important. This can be achieved with oxygen, 0 2 . If this is added to the exhaust gas in front of the exhaust filter, it can act as a radical on the filter and thus serve to clean the filter.
- a separating agent such as a diaphragm may be provided for separating the hydrogen gas and the oxygen gas which are producible in the electrolysis chamber.
- a conduit for sending a portion of the oxygen gas to the exhaust filter is mounted, wherein the light guided from the supply line to the combustion chamber gas mixture, the rest of oxygen gas (is thus "which is not directed to the proportion of the oxygen gas to the exhaust gas filter) include and the hydrogen gas and the gasified organic compounds can.
- the separation of the generated oxygen gas and hydrogen gas can take place at any point in principle. It is also possible that oxygen gas and hydrogen gas are conducted from the electrolysis chamber to the combustion chamber without separation, while a portion of this explosive gas mixture (that is, the mixture with oxygen gas and hydrogen gas) is branched off into a separate line and only there with the separating agent in oxygen gas and separated therefrom Hydrogen gas is separated.
- the electrolysis chamber is supplied with an electric current through which the hydrogen gas and the oxygen gas are recovered in the electrolysis chamber.
- water is introduced, from which the hydrogen gas and the oxygen gas are generated.
- control means are provided and adapted to control the electrical current and / or a water introduction into the electrolysis chamber and / or a pumping power of the vacuum pump depending on a momentary characteristic of an internal combustion engine operation.
- the control can in particular be such that the amount of injected gas mixture is greater, the more diesel is injected in a given period. Accordingly, the gas mixture produced does not serve as a substitute for a fossil fuel carrier. Rather, the gas mixture is used as an additive, which affects the combustion process in a desirable manner.
- control means may adjust the flow and the pumping power such that a ratio of injected diesel to the introduced gas mixture is substantially congruent. is essentially independent of an injection rate and an injected amount of diesel.
- substantially constant variations of at most 10%, preferably at most 5%, of the aforementioned ratio can be considered.
- the control means are adapted to use as a current characteristic of the engine operation, depending on which the electric current and the pump power are controlled to use a boost pressure of the internal combustion engine.
- the boost pressure denotes an air pressure in an intake pipe of the internal combustion engine.
- the control means may now be adapted to set the electric current and the pump power the higher, the higher the charge pressure.
- another pressure dependent thereon can be used instead of the boost pressure for the control, for example an exhaust gas pressure, in particular in front of a turbocharger.
- suitable pressure-measuring means can expediently be present.
- a pressure associated with the engine power size can be used for the control, such as an accelerator pedal signal or an engine speed. Under certain circumstances, however, it may be easier to use errors when using such electrical signals as when controlling the (charge) pressure.
- an air pump is also provided for pumping air into the gasification tank.
- the air may be ambient air, in particular a mixture of any gases.
- the more air that is pumped into the gasification tank the greater the amount of gassed organic compounds. As a result, the amount of gas mixture generated is increased. This is desirable if a fossil fuel is burned in the combustion engine at a particularly high rate and accordingly a particularly large amount of gas mixture produced should be supplied.
- the vacuum pump is operated with increasing pump power when the boost pressure increases. It can be provided that the vacuum pump operated at maximum pump power is when the boost pressure reaches a predetermined boost pressure value. Now increases the boost pressure above this predetermined boost pressure value, it would be desirable to supply an even larger amount of gas mixture.
- the amount of oxygen gas and hydrogen gas is limited by the vacuum pump and the electrolysis chamber, a larger amount of gassed organic compounds can be supplied by means of the air pump. Therefore, it can be provided that in addition the air pump is operated when the boost pressure rises above the predetermined boost pressure value.
- a performance of the air pump can be adjusted the higher the further the boost pressure rises above the predefined boost pressure value.
- the vacuum pump is always operated with maximum pumping power.
- the composition of the gas mixture changes due to the air pump, this is nevertheless better than an insufficiently large amount of available gas mixture.
- a different pressure can be used, which depends on the boost pressure (for example, an exhaust gas pressure).
- the boost pressure and a different size can be used, which increases with increasing engine power, such as the engine speed.
- a storage tank is present and connected to the gasification tank.
- the storage tank contains organic compounds and is used to fill the gasification tank.
- a manual filling of the gasification tank can be provided via a closable opening on the gasification tank.
- ignition of injected diesel in the combustion chamber can be effected by introducing the gas mixture.
- the gas mixture which includes oxyhydrogen, the combustion can be done faster. It may be preferred that an ignition timing at a crankshaft angle of less than 20 °, in particular between 17 ° and 19 °, in particular between 17.5 ° and 18.5 ° before the top dead center (a piston of the internal combustion engine) is effected.
- This ignition timing may be predetermined and controlled by the timing of introducing the gas mixture into the combustion chamber. In this embodiment, therefore, the ignition occurs closer to top dead center than usual.
- Such a later ignition point may be chosen because the combustion in the invention runs particularly fast. At a desired time, such a higher pressure can be generated.
- the invention further relates to a land vehicle, for example a lorry, a passenger car, an excavator or another utility vehicle, with a vehicle drive system formed as described herein,
- Fig. 1 is a schematic representation of an embodiment of a vehicle drive system according to the invention.
- Fig. 1 shows schematically an embodiment of a vehicle drive system 100 according to the invention. This may be part of a land vehicle, not shown here, for example, a truck.
- the vehicle drive system includes an electrolysis chamber 20 for generating hydrogen gas and oxygen gas, a gasification tank 30 for gasifying volatile organic compounds, and an internal combustion engine 50. to which besides a fossil fuel carrier, the generated hydrogen gas, oxygen gas, and gaseous organic compounds are also supplied.
- a line system 28 the generated hydrogen gas and the generated oxygen gas are conveyed. These two gases can be present in particular as a mixture, that is to say as an oxyhydrogen gas.
- a vacuum pump 25 is present in the line system 28. This generates a negative pressure in the electrolysis chamber 20, whereby the oxygen gas and the hydrogen gas are sucked off.
- the negative pressure in the electrolysis chamber 20 causes smaller amounts of electrolyte, which is present in the electrolysis chamber 20, to pass from the liquid phase into gaseous form. Thereby, the efficiency of the electrolysis chamber 20 can be increased.
- the piping system 28 supplies the oxygen gas and the hydrogen gas to the gasification tank 30.
- organic compounds for example, methanol and / or ethanol, which undergo surface gasification by the introduction of the hydrogen gas and the oxygen gas.
- the hydrogen gas and the oxygen gas in a lower part, in particular at the bottom of the gasification tank 30 are introduced into this.
- a gas mixture is thus generated which comprises at least hydrogen gas, oxygen gas and gasified organic compounds, in particular methanol and / or ethanol. This gas mixture is then passed on via a supply line 38.
- the supply line 38 leads the generated gas mixture to a compressor 42 of a turbocharger 40.
- the gas mixture can be guided together with ambient air to the compressor 42.
- a corresponding line may be present (not shown).
- the gas mixture passes into a combustion chamber 52 of the internal combustion engine 50.
- the combustion chamber 52 ignites the gas mixture and causes combustion of also injected diesel fuel.
- Exhaust gases are conducted from the combustion chamber 52 via an exhaust pipe 54 to a ⁇ bgasturbine 44 of the turbocharger 40.
- a pressure of the exhaust gas is therefore used by the exhaust gas turbine 44 in order to convey the gas mixture with the compressor 42 in the direction of the internal combustion engine 50.
- the exhaust gas passes to an exhaust filter 60th
- a supply of the gas mixture into the combustion chamber 52 should be greater, the greater the amount of injected diesel fuel.
- the turbocharger 40 is used.
- the compressor 42 of the turbocharger 40 is driven by the ⁇ bgasturbine 44. This drives the compressor 42 all the more, the higher the exhaust gas pressure at the exhaust gas turbine 44. If only small amounts of diesel are combusted in the combustion chamber 52, consequently, the pressure at the ⁇ bgasturbine 44 is low and the compressor 42 also generates only a small intake in the supply line 38. However, larger amounts of diesel are burned in the combustion chamber 52, the compressor 42 cause a stronger suction of the gas mixture from the supply line 38.
- control means 10 are provided, which in particular can set an electric current through the electrolysis chamber 20 and thus can specify the amount of hydrogen gas produced and oxygen gas.
- control means 10 can control the vacuum pump 25 and thus adjust how much hydrogen gas and oxygen gas is conveyed from the electrolysis chamber 20 into the gasification tank 30.
- a larger electric current and a higher pumping power of the negative pressure pump 25 can be set. The higher the rate or amount of injected diesel into the combustion chamber 52, the greater the amount of gas mixture produced. As a measure of this, the boost pressure of the internal combustion engine 50 can be used.
- control means 10 may be adapted to increase the pump power of the vacuum pump 25 and the electric current in the electrolysis chamber 20 with increasing boost pressure.
- Corresponding pressure measuring means may be present.
- pressure measuring means 12 are provided which measure an exhaust gas pressure upstream of the turbocharger 40. Also, this exhaust pressure can be used to control the amount of gas mixture generated.
- an air pump 35 is additionally present. This pumps air, in particular ambient air, into the gasification tank 30 and thus causes an increased gasification of the organic compounds. It may be advantageous if a line from the air pump 35 and the line system 28 on the vacuum pump 25 open into a common line, so that air from the air pump 35 and the hydrogen gas and oxygen gas obtained by electrolysis are introduced into the gasification tank 30 via the same nozzles , In other embodiments, it may also be advantageous if the air from the air pump 35 and the generated hydrogen gas and oxygen gas via separate lines in the gasification tank 30 arrive.
- a pumping power of the air pump 35 is also set via the control means 10. It can be provided that the air pump 35 is operated only when the electrolysis chamber 20 is supplied with maximum current and the vacuum pump 25 operates at maximum pump power.
- the exhaust gas filter 60 In order to purify the exhaust gas filter 60 particularly effectively, it can be supplied with oxygen gas from the electrolysis chamber 20.
- a line 82 is present, which leads from the electrolysis chamber 20 to the exhaust filter 80.
- a design of the electrolysis chamber 20 may be preferred in which either oxygen gas is separated from the hydrogen gas and conveyed without conduit 62, or where oxygen gas and hydrogen gas are conveyed together via conduit 62.
- the generated gas mixture is fed to the fossil energy carrier in the combustion chamber 52, a particularly rapid combustion can take place.
- the ignition can be reached especially shortly before a top dead center of a piston. bens of the internal combustion engine 50, which is a higher efficiency.
- the amount of pollutants generated in the exhaust gas is a higher efficiency.
