- a reciprocating engine for example for a gasoline direct injection engine in a motor vehicle, with NO x combustion -deficient (NAV).
- NAV NO x combustion -deficient
- Downsizing involves designing, deploying and operating smaller displacement engines to achieve comparable or improved driveability values, unlike their previous large displacement engines. By downsizing the fuel consumption can be reduced thereby reducing the C0 2 emissions. In addition, smaller displacement engines have lower absolute friction losses.
- cubic capacity engines are characterized by a lower torque, especially at low speeds, and thus lead to a poorer dynamic behavior of the vehicle, and thus for example to a poorer elasticity.
- operating method disadvantages which brings the downsizing of gasoline engines, at least largely be compensated.
- an operating method in which a lean fuel / exhaust gas / air mixture in the respective combustion chamber of the internal combustion engine is caused to autoignite. So that the compression ignition starts at the desired time, fuel is injected into the combustion chamber in the lean, homogeneous fuel / exhaust gas / air mixture with corresponding compression shortly before spark ignition, so that a more greasy mixture cloud is formed. Embedded in the lean, homogeneous fuel / exhaust gas / air mixture, this concentrated mixture cloud serves as the ignition initiator for the compression-ignited combustion in the combustion chamber.
- CONFIRMATION COPY DE 10 2006 041 467 A1 describes an operating method for a gasoline engine with homogeneous, compression-ignited combustion. If, in the respective combustion chamber of the internal combustion engine, the homogeneous fuel / exhaust gas / air mixture, which is lean, is compressed, then in contrast to the spark ignition, Otto engine operating method and starting from the ignition point in the combustion chamber no flame front combustion occurs, but the homogeneous fuel - / Exhaust / air mixture ignited in the respective combustion chamber at a corresponding compression rate at several points almost simultaneously, so that adjusts a Jardinzündverbrennung in this case.
- Room ignition combustion has a significantly lower nitrogen oxide emission and at the same time a high fuel consumption efficiency compared with the Otto engine, spark ignition operation.
- this low-emission, efficient RZV method of operation with room ignition combustion can only be used in a lower and possibly in a medium engine load / engine speed range, since with decreasing charge dilution the tendency to knock increases and thus the use of the RZV operating method is limited to higher engine load ranges.
- the present invention is now concerned with the problem of providing an improved or at least an alternative operating method for a, in particular direct injection, internal combustion engine, which is characterized in particular by a safe operating stability, inter alia in a higher engine load range with simultaneous low NO x combustion.
- the invention is based on the general idea, in an operating method for a, in particular directly injected, multiple combustion chambers having internal combustion engine, in particular for a directly injected gasoline engine, for example a motor vehicle, with at least partial low NO x combustion (NAV) and with several partial operation to switch between an RZV partial operating method with pure room ignition combustion (RZV) and a NAV partial operating method, wherein in the case of the NAV partial operating method at an ignition time (ZZP) a substantially homogeneous nes, lean fuel / exhaust gas / air mixture with a combustion air ratio of ⁇ 1 in the respective combustion chamber is externally ignited by an ignition device and a started by the spark ignition flame front combustion (FFV) in a room ignition combustion (RZV) passes.
- NAV ignition time
- a room ignition combustion (RZV) is also possible in engine load and / or engine speed ranges, in which a pure RZV partial operating method can only be carried out to a limited extent due to its low operating instability. Due to the widening of the map area, in which a Jardinzündverbrennung is feasible, thus a low NO x combustion is possible in a larger operating range of the internal combustion engine, at the same time high efficiency in terms of fuel consumption.
- a direct injection, multiple combustion chambers having internal combustion engine can be operated by various operating methods or with different partial operating methods. So several ottomotorische partial operating methods are possible.
- the stoichiometric, partial engine operating mode can be used throughout the engine load and / or engine speed range. It is preferably also used when other partial operating methods are used in the high engine load and / or engine speed range.
- An Otto engine partial operating method can also be carried out externally ignited with excess air and thus with a combustion air ratio ⁇ > 1.
- This partial operating method is usually also referred to as a DES partial operating method (direct injection layer), wherein a stratified, generally lean fuel / exhaust gas / air mixture is formed in the respective combustion chamber by means of a plurality of direct injections. Due to the layered design, at least idealized two partial areas with a different combustion air ratio ⁇ are arranged in the respective combustion chamber. This stratification is usually generated by multiple injections. In this case, a lean, homogeneous fuel / exhaust gas / air mixture in the respective combustion chamber can first be formed by one or more injections.
- HOS Hemogeneous Layer
- the DES and HOS sub-operations may also be compression-ignited and are then typically no longer referred to as DES, HOS sub-operations.
- the RZV partial operation method can be used, in which a lean, homogeneous fuel / exhaust gas / air mixture is started in the respective combustion chamber by space ignition combustion and thus compression ignited.
- a partial engine operating mode in which a flame-front combustion (FFV) occurs by means of spark ignition
- the fuel / exhaust gas / air mixture arranged in the respective combustion chamber begins to be ignited almost simultaneously in several areas of the respective combustion chamber, so that a room ignition combustion occurs.
- the RZV partial operating procedure has a significantly lower NO x emission than the partial engine operating modes and is characterized by a lower fuel consumption.
- the NAV partial operating method according to the invention can now be understood as a combination of a spark-ignited, Otto engine partial operating method and an RZV partial operating method.

- the combustion is externally ignited by an igniter.
- the operating stability of the mixture ignition and / or combustion significantly improved.
- the homogeneous, lean fuel / exhaust gas / air mixture begins to burn in the manner of an internal combustion engine flame-retardant combustion (FFV), which then subsequently passes into a room-temperature combustion (RZV).
- FFV internal combustion engine flame-retardant combustion
- RZV room-temperature combustion
- the NAV fractional operation method combines the advantages of room ignition combustion (RZV) and gasoline engine, operational stable ignition of the fuel / exhaust gas / air mixture. Controlled by the provision of a correspondingly composed fuel / exhaust gas / air mixture in the respective combustion chamber and controlled by the spark ignition by means of an ignition device at the right time, this NAV partial operation method according to the invention can be carried out.
- the NAV partial operation method is characterized by a low pressure gradient and a reduction in knock tendency. Accordingly, by means of the NAV partial operating method, a room ignition combustion (RZV) in a higher engine load range feasible in which the pure RZV partial operation method due to the increasing pressure gradient and due to irregular combustion conditions, especially because of the increased tendency to knock, can no longer be carried out sufficiently stable operation.

- the combustion air ratio is a dimensionless physical quantity describing a mixture composition of a fuel / exhaust gas / air mixture.
- the mixture composition of the fuel / exhaust gas / air mixture can be specified by the charge dilution.
