Definitions
- the invention relates to a method for operating a spark-ignited internal combustion engine, wherein in at least one engine operating region to increase the combustion chamber temperature, the ignition timing of at least one ignition device is pre-adjusted.
- Emission limit values in particular for light road vehicles, are very stringent by legal requirements, for example by the Euro 6 standard, especially with regard to particulate and nitrogen oxide emissions. These requirements are aimed, among other things, at significantly reducing the number of particles in vehicle emissions.
- the catalyst heating operation serves to bring the catalyst as quickly as possible to the light-off temperature (light-off temperature).
- Various methods for heating the catalyst are known.
- DE 101 14 050 A1 describes engine measures for heating a catalytic converter, wherein the engine measures consist of a multiple injection and / or an ignition retard adjustment.
- the combustion is very sensitive to the formation of particles, both in terms of particle mass, as well as the number of particles. In particular, the particle mass and the number of particles multiply during dynamic processes.
- WO 2006/105562 A1 describes a method for operating a spark-ignited internal combustion engine having at least one ignition device, wherein at least in one operating region a Rußabbrand is performed by increasing the thermal energy input, the ignition of the ignition device is adjusted immediately after the start of the engine.
- This measure is completely independent of Katalysatoretzloom compassion and regardless of whether a dynamic or stationary operation is present and aims only to eliminate the deposits within the combustion chamber, in particular on the combustion chamber walls and the ignition device.
- the object of the invention is to significantly reduce the number of particles and / or particulate mass in the emissions of a spark-ignition vehicle during the warm-up phase. According to the invention this is achieved in that the advance of the ignition is carried out during at least one Katalysatorterrorism horres. The advance of the ignition can also be done several times in the catalytic converter operation.
- a catalyst heating operation it is checked via a control unit constantly or at defined time intervals, if a catalyst heating operation is present. If it is determined that the internal combustion engine is operated in a catalytic converter heating operation, it is checked in a further method step whether dynamic operation is imminent.
- the two test steps can also be temporally swapped or simultaneous.
- the imminent dynamic operating case for example, due to a dynamic operation triggering action of the driver, such. As clutch actuation, gear operation or accelerator pedal operation, or be established by vorrauquartde, based on a driving guidance system or navigation system route recognition.
- the pre-adjustment of the ignition leads to an increase in the combustion chamber temperature. It has been found that by increasing the combustion chamber temperature by advancing the ignition of the ignition device, the number of particles and the particle mass in the emissions can be substantially reduced. This reduction in particulate emissions is attributable to the fact that the higher combustion chamber temperature promotes mixture formation, which results in a significant reduction in particle mass and particle number. Furthermore, dynamic processes are reduced in the engine warm-up phase, which also exert an influence on the particle formation.
- the Fig. 1 shows the method according to the invention in a flow chart.
- step 20 After a cold engine start 10, it is checked in step 20 whether there is a catalyst heating operation or whether the catalyst temperature is below the light-off temperature. If this is the case, a further test step 30 investigates whether a dynamic operating case is imminent. In case that If there is no catalyst heating operation or that the light-off temperature of the catalytic converter has been reached, the method can be terminated (step 50) and restarted only at the next engine start. Alternatively, the query 20 can be continued continuously or at defined time intervals in a loop indicated by the dotted line.
- step 40 the ignition for the individual cylinder igniters is presented at least 5 °, preferably at least 10 ° (based on the catalyst heating operation), until either the dynamic one Operation is completed or until the light-off temperature of the catalyst is reached. If multiple dynamic operations are detected in the catalyst heating mode, the ignition can be advanced several times over a time interval direction early.
