Embodiment Construction

[0104] figure 1 An embodiment of a spark-ignition internal combustion engine 1 for carrying out the method is schematically shown.

[0105] The internal combustion engine is a six-cylinder internal combustion engine 1 in which the cylinders 3 are arranged distributed in two cylinder banks (ie in the present case in two cylinder heads 6 a and 6 b ) and form two groups. Each cylinder head 6 , 6 a , 6 b contains a group of three cylinders 3 . An exhaust duct 4 is provided to release hot combustion gases and an intake duct 2 is provided to supply fresh air or a fresh mixture to the cylinder 3 .

[0106] For the purpose of exhaust gas aftertreatment, the internal combustion engine 1 is equipped with a particulate filter 5 arranged in the exhaust gas line 4 . Furthermore, an engine controller 7 is provided, by means of which the internal combustion engine 1 , ie the operating parameters of the internal combustion engine 1 , are controlled and / or regulated.

[0107] By adjusting a...

Abstract

The invention involves a method to start an explosive motor (1) with spark ignition and the explosive motor (1) has more than one cylinder stator (3) and at least one exhaust duct (4) with a particulate filter (5), which is used for collecting and combusting carbon black contained in the exhaust, settled inside. The explosive motor (1) is also equipped with an engine controller (7). The invention also involves the particular explosive motor (1) suitable for the method mentioned. The invention aims to find a method of ensuring or allowing the high-level and effectiveness of a particulate filter by the method and device. The method is characterized by adjusting at least one operating parameter to increase the discharge of original particles in the explosive motor (1) so as to increase the load of the particulate filter (5) and to improve the efficiency of the particulate filter (5).

Description

technical field [0001] The invention relates to a method for operating a spark ignition internal combustion engine having at least one cylinder and at least one exhaust duct for releasing exhaust gas from said at least one cylinder, in which exhaust duct a particulate filter is arranged , for collecting and burning soot particles contained in the exhaust gas, and the internal combustion engine is equipped with an engine controller. [0002] The invention also relates to a spark-ignition internal combustion engine for carrying out a method of the type described above. Background technique [0003] Spark ignition internal combustion engines are used as drives for motor vehicles. In the context of the present invention, the expression "spark ignition internal combustion engine" includes any type of four-stroke engine equipped with spark ignition, but also especially hybrid internal combustion engines, that is to say internal combustion engines that operate with a mixed combust...
