Problems solved by technology

Due to the low raw particulate emissions of four-stroke engines, the adjustment of the filter (i.e. the formation of the desired pore size) would take an unacceptably long time
In addition, higher operating temperatures, whether desired or not, will result in more frequent filter regeneration, which offsets the required buildup of filter blocks and promotes oxidation of soot

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 method involves providing an internal combustion engine (1) with a cylinder (3). An exhaust pipeline (4) is provided with a particulate filter (5). The exhaust pipeline is utilized for collecting and burning carbon smoke particles. The internal combustion engine is equipped with an engine controller (7). The internal combustion engine is operated by adjusting operating parameter particulate emissions to accelerate the particulate filter and increasing efficiency of the particle filter. An internal combustion engine parameter of injection is adjusted to increase original particles. An independent claim is also included for a spark ignition combustion engine operating device.

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...
