Definitions
- an exhaust gas purification system which comprises, for example, at least one catalytic converter and optionally a particle filter.
- the predetermined time duration is predetermined depending on a temperature of the at least one catalytic converter and / or an exhaust gas temperature and / or an exhaust gas mass flow and / or a particle number in the combustion chamber exhaust gas and / or the specified particle number emission limit value.
- the advantage is that in this way the predetermined period of time can be selected as long as necessary and as short as possible in order to be able to increase the hydrocarbon concentration in the combustion chamber exhaust gas as early as possible in order to reduce the particle number, but without the prescribed hydrocarbon emission limit value To exceed.
- the predetermined period of time can also be set to zero if the catalytic converter already has its operating temperature.
- the predetermined time duration can be set the shorter, the higher the exhaust gas temperature and / or the exhaust gas mass flow.
- the predetermined time period can also be set to zero or short, if in the current operating state of the internal combustion engine, the particle number in the combustion chamber exhaust gas is so low that the predetermined particle number emission limit without or by only slightly increasing the hydrocarbon concentration in the combustion chamber exhaust gas for reduction the particle number can be maintained.
- the predetermined period of time is a maximum of 20 seconds.
- the exhaust gas purification or emission reduction system in particular in a diesel internal combustion engine, a particulate filter for filtering in particular large, that is, high-mass particles from the exhaust gas and / or recirculation of exhaust gases from the exhaust system 4 and / or the combustion chamber 9 in the intake tract 1 and the combustion chamber 9 include.
- an exhaust gas recirculation rate may be set, for example, by a valve overlap phase in which the gas inlet valve 12 and the gas outlet valve 13 are simultaneously opened.
- the recirculation of the exhaust gases for example, causes a lower combustion temperature in a combustion process in the combustion chamber 9 than without the recirculation of the exhaust gases.
- the lower combustion temperature may result in lower pollutant production in the combustion process than at a higher combustion temperature.
- the sensors are, for example, a pedal position sensor 26 that detects an accelerator pedal position of an accelerator pedal 27, an air mass sensor 28 that detects an air mass flow upstream of the throttle 5, a throttle position sensor 30 that detects an opening degree of the throttle 5, a first temperature sensor 32 that detects an intake air temperature , a second temperature sensor 33 detecting a cooling water temperature, a third temperature sensor 35 detecting an oil temperature, an intake manifold pressure sensor 34 detecting an intake manifold pressure in the accumulator 6, a crankshaft angle sensor 36 detecting a crankshaft angle then a speed is assigned.
- a pedal position sensor 26 that detects an accelerator pedal position of an accelerator pedal 27, an air mass sensor 28 that detects an air mass flow upstream of the throttle 5, a throttle position sensor 30 that detects an opening degree of the throttle 5, a first temperature sensor 32 that detects an intake air temperature , a second temperature sensor 33 detecting a cooling water temperature, a third temperature sensor 35 detecting an oil temperature, an intake manifold pressure sensor 34 detecting an intake manif
- a step Sil can be provided to detect the temperature TEMP_KAT of the at least one catalytic converter 24 and in particular of a close-coupled catalytic converter and to check whether this at least one catalytic converter 24 already has its operating temperature TEMP KATB for the conversion of hydrocarbon HC. If this is not the case, this at least one catalytic converter 24 is brought to at least its operating temperature TEMP_KATB within a predetermined period of time T.
- a step S12 may be provided for determining the required time duration and predetermining this determined time duration as the predetermined time duration T.
- a step S13 at least one of the at least one exhaust gas catalytic converter 24, in particular the exhaust gas catalytic converter 24 next to the engine, is brought to at least its operating temperature TEMP_KATB for the conversion of hydrocarbon HC within the predetermined period of time T.
- the operating mode B of the internal combustion engine is predetermined to maintain the predetermined hydrocarbon emission limit value HCE, that is, the predetermined injection strategy ES for increasing the hydrocarbon concentration HCK is preferably not used during the predetermined period of time T.
- the minimum hydrocarbon concentration HCMK is determined.
