Within the scope of this invention, if identifying the air fuel mixture and the fuel being introduced in combustion chamber for participating in burning
The deviation of amount, then can particularly simply be inferred to the fuel deposited on the wall of combustion chamber.
In the case where air fuel mixture is uniformly distributed in air-fuel ratio as optimal as possible, fuel can
To burn as optimally as possible, harmful substance as few as possible is thus left, which for example can further be located in catalyst converter
Manage and/or be discharged in environment.But if such as fuel is introduced in combustion chamber now, which does not become air fuel mixing
A part for thing, but the lubrication for being for example deposited on the wall of combustion chamber and/or entering on the wall of combustion chamber in the case
In film, especially at piston, then this can cause poor discharge value.But now can be very by the method that advises
The deposition of this fuel on the wall of combustion chamber is simply identified.Only when the deviation of two fuel quantities is more than a threshold value

Burn cycle changes a jet mode for being arranged by means of the fuel quantity that directly injection is introduced in combustion chamber.For drawing
The excessive situation of the fuel quantity that enters, alternatively or additionally, it is also possible to, although for example by means of the combustion for directly spraying introducing
Doses can be mixed with air, but be introduced too quickly.The coupling of course of injection now can for example be carried out herein, for example
By improving the injection pulse quantity with the less emitted dose of difference.This also realizes the fuel for simply avoiding deposition.
Advantageously, one is lacked due to the direct injection being changed further at least one later burn cycle
Few fuel quantity is introduced in combustion chamber by means of intake manifold injection.The fuel quantity that will be generally introduced in combustion chamber by this way
Can keep identical, i.e., need not stand power loss, but simultaneously keep the discharge value that described advantage for example improves.
This is especially possible in the case where dual system, i.e. intake manifold injection and the combination that directly sprays is utilized, and the dual system is realized to two
The simple change of the distribution in individual spray regime.
Preferably, if for the direct injection that at least one later burn cycle is changed include than normal directly
Change of the injection more than a threshold value, then be inferred to the function limitation of the direct injection.Due to usually in design fuel
Attempt to realize the sedimentation of fuel as few as possible on chamber wall during injector, if still existed very on chamber wall
High sedimentation of fuel, then can be with it is thus regarded that there is function limitation in related fuel injector.This function limitation example
Such as can due at fuel injector or the inside deposit and/or fuel injector abrasion or defect produce.Therefore build
Thus the method for view is also realized, to spraying system, especially directly spraying(System)Very simple fault diagnosis.

Deviation A can be so identified, it is possible thereby to the deposition of the fuel being inferred on the wall of combustion chamber.
Especially here is noted that in internal combustion engine.Here, as tune
Section parameter, it is possible to use the control time of fuel injector.If there is now the deviation of the very little of the desired value of λ value, then
The control time of fuel injector can be changed in this wise so that λ value is close to desired value.
If now it can be stated that λ value λ in the scope of this regulationistSignificantly, especially with more than one really
Fixed threshold value ground, deviates from λ value λsoll, then identify deviation in the sense of the present invention.This big deviation is for example known
It is not a kind of discontinuity during regulation(Unstability).
In the case of deviation A of identification, can also for example change now the direct injection for subsequent burn cycle
Jet mode.It may be thus possible, for example, to improve injection pulse quantity, thus same fuel quantity is distributed on multiple injection pulses
On, this typically results in preferable mixture and is formed.
Alternatively or additionally, can also for example limit for subsequent burn cycle, introduced by means of directly injection
Fuel quantity M in combustion chamberD.It may be thus possible, for example, to prevent than for forming the more fuel of mixture by means of directly spray
Penetrate and be incorporated in combustion chamber.In connection with this, now correspondingly can also improve burning will be incorporated into by means of intake manifold injection
Fuel quantity in room, is thus generally used for the fuel quantity that burn cycle is introduced in combustion chamber and keeps constant.Certainly, for example may be used
With necessary to correspondingly change or consider based on the burden requirement for changing, the fuel quantity that is changed.
