- a direct or assisted starting of the engine by an early combustion requires certain constraints to be successful to be able to. For example, it is necessary or advantageous that the Crankshaft at the beginning of cranking in or near a certain position stands. It must also be ensured that sufficient combustion Power for driving the internal combustion engine can be obtained. The latter in turn sets the provision of a sufficient amount of fresh air during the start phase ahead.
- DE 199 47 784 A1 the Arrangement of an air storage space proposed in which air under a increased pressure is to be stored, so that these at a direct start of the Internal combustion engine can be fed into the cylinder and there for a increased boost pressure ensures.
- the method according to the invention serves to start an internal combustion engine, already during the starting phase, fuel combustion in at least a combustion chamber of the internal combustion engine takes place.

- the starting can be assisted by means of an auxiliary unit, so that the latter can be designed more easily and therefore cheaper.
- auxiliary unit Preferably With the combustion even a direct start of the internal combustion engine performed, which gets along completely without additional auxiliary unit.
- the procedure is characterized in that during the starting phase (respectively) before the beginning a combustion in at least one combustion chamber of the internal combustion engine one compared to the relative oxygen concentration in normal air (about 21 vol .-%) increased relative oxygen concentration prevails (whereby fuel gases and / or residual exhaust gases in the determination of the relative concentration not be taken into account).
- an oxygen donor in at least one combustion chamber of the internal combustion engine to be available.
- An oxygen donor is one preferably gaseous or liquid substance, which oxygen chemically bound contains and this under certain conditions, for example Above a temperature threshold, release or to other chemical substances can deliver.
- the increased oxygen concentration in the combustion chamber can be improved by supplying a gas that has oxygen in a relation to the conditions in normal air contains increased concentration or even consists of pure oxygen (hereinafter Called "oxygen supply gas"), during the running out of the internal combustion engine, during the stoppage of the internal combustion engine and / or during the Start phase of the internal combustion engine are generated.
- the supply can additionally take place to or instead of the normally sucked fresh air.
- the oxygen donor may leak during standstill and / or the starting phase of the internal combustion engine are supplied. At all mentioned Supply types ensures that the oxygen or the Oxygen donor is available during the startup phase.
- the oxygen donor is during the operation of the internal combustion engine on board of the internal combustion engine containing Motor vehicle produced and for starting the internal combustion engine cached.
- the type of production depends on the oxygen donor used substance.
- An oxygen donor preferably used in this context is the gas nitrogen monoxide N 2 O ("nitrous oxide").
- This gas can either be carried in a store or generated aboard a motor vehicle in a suitably equipped reactor from suitable starting substances or, for example, by biotechnological processes.
- the nitrogen monoxide N 2 O is recovered during operation of the internal combustion engine in a arranged in the exhaust path of the internal combustion engine exhaust gas catalyst.
- the formation of N 2 O is suppressed by special measures.
- the invention further relates to an internal combustion engine, preferably an internal combustion engine with direct injection and spark ignition, which characterized is that this means of providing gas with a higher relative oxygen concentration as in air (“oxygen feed gas”) and / or from an oxygen donor in at least one combustion chamber of the internal combustion engine contains.
- an internal combustion engine preferably an internal combustion engine with direct injection and spark ignition, which characterized is that this means of providing gas with a higher relative oxygen concentration as in air (“oxygen feed gas”) and / or from an oxygen donor in at least one combustion chamber of the internal combustion engine contains.
- the internal combustion engine is for carrying out a method of the above Kind furnished.
- the provision of oxygen supply gas and / or a Oxygen donor can thus for the startup phase of the internal combustion engine take place in order to start this way by early fuel burns support or cause a direct start.
- this contains a storage device for oxygen supply gas and / or for an oxygen donor, wherein the Supply storage via supply lines with at least one combustion chamber of Internal combustion engine is connected.
- a storage memory can with a Refueling be provided so that this periodically, For example, when refueling the vehicle with fuel, refilled can be.
- the internal combustion engine further preferably includes an exhaust gas aftertreatment device arranged in the exhaust path and configured to generate and / or separate N 2 O from the exhaust gas coming from the internal combustion engine.
- the internal combustion engine is autonomous, since it generates the oxygen donor itself and in this respect no regular refueling od. Like. Needed.
- the invention further relates to a device for obtaining an oxygen donor, in particular of nitrogen monoxide N 2 O, which is designed to generate from the exhaust gas of an internal combustion engine, the oxygen donor and / or to separate.
- the device may in particular be a suitably designed or modified catalytic converter.
- An internal combustion engine equipped with such a device is able to autonomously generate an oxygen donor, which can be used in particular during the starting phase of the internal combustion engine to provide a sufficiently high amount of oxygen for a powerful combustion and thus a starterless starting of the internal combustion engine.
- the internal combustion engine 2 shown in the figures is in particular to such with direct injection of fuel into the cylinder and Spark ignition.
- the internal combustion engine is via an intake manifold or an intake system 1 provided fresh air.
- the combustion gases are discharged via an exhaust manifold and an exhaust path 4.
- In the exhaust path 4 is at least one exhaust aftertreatment device 3, z. B. a three-way catalyst.
- FIG. 1 shows in this regard a first specific embodiment of the invention.
- they are filled with pure oxygen O 2 instead of fresh air or in addition to the fresh air.
- an oxygen donor ie, gases or liquids that contain oxygen chemically bound and can release it in the cylinders.
- the oxygen donor is preferably introduced into the cylinders in addition to the normal fresh air.
- the pure oxygen O 2 and / or the oxygen donor which may, for example, be nitrogen monoxide N 2 O, is stored in a storage tank 6 on board the motor vehicle and introduced via supply lines 5 as required into the cylinders of the internal combustion engine ,
- This supply of oxygen or an oxygen donor can during the running of the internal combustion engine (ie in the time from switching off the ignition and / or fuel supply to engine standstill), during engine stall (zero speed) and / or during the starting phase (ie from engine stall until reaching a predetermined minimum speed, for example, the idling speed).
- the provision of pure oxygen gas O 2 or oxygen released from an oxygen donor in the combustor increases the total available amount of oxygen in the combustor. Therefore, an additional amount of fuel can be provided by the direct injection and completely burned, so that a larger energy is obtained from the combustion process. This ensures that the internal combustion engine 2 can be started directly by the combustion "on its own”.
- the oxygen gas O 2 and / or the oxygen donor can be replenished in the reservoir 6 by a tank device 7 if required.
- Figure 2 shows a modification of the system of Figure 1.
- the memory 6 ' is specifically a N 2 O memory, which is connected on the input side via a line 8 to the exhaust gas catalyst 3.
- Nitric oxide N 2 O is an oxygen carrier with about 1.5 times the density of air.
- N 2 O dissociates at temperatures above 300 ° C into oxygen and nitrogen according to the formula 2N 2 O ⁇ 2N 2 + O 2 .
- N 2 O can be introduced into the cylinders of the internal combustion engine 2 together with fresh air for a direct start. With the fresh air and a fuel injection combustion can be initiated in a cylinder, which is in the correct working position for this purpose. When the temperature rises above 300 ° C due to combustion, oxygen is released from the N 2 O, which then participates in the combustion. Due to the additional amount of oxygen provided by this release, a corresponding additional amount of fuel can be reacted in the combustion chamber. As a result, the available energy for starting the internal combustion engine increases accordingly, so that a direct start is more likely to be successful or more robust under critical boundary conditions.
- the N 2 O gas can be stored in the motor vehicle in a storage device 6 such as a pressure bottle, which is refilled if necessary.
- a storage device 6 such as a pressure bottle
- N 2 O is generated on board the motor vehicle in a suitable reactor for this purpose.
- N 2 O can be generated under the action of heat from solid ammonium nitrate NH 4 NO 3 .
- N 2 O can be produced by denitrification in a biotechnological process by specific nitrate bacteria and fungi. The nitrate is from time to time replenished in the reactor.
- N 2 O generation in the motor vehicle is to be particularly preferred since it manages with the fewest additional devices.
- the N 2 O is generated in the exhaust catalyst 3 from the exhaust emissions of the internal combustion engine 2 or separated.
- large amounts of N 2 O are formed in catalysts during reduction processes in an oxygen-rich atmosphere on the platinum metal of the catalyst.
- additional measures must be taken.
- the formation process of N 2 O is exploited in order to build up an N 2 O storage medium on board the motor vehicle, which can then be used during a direct start.
- the advantage of this approach is that no replenishment of special substances (such as N 2 O itself or ammonium nitrate) is required.
