Embodiment Construction

[0019] exist figure 1 shows an internal combustion engine 1 of a motor vehicle, in which a piston 2 can reciprocate in a cylinder 3 . Cylinder 3 is provided with a combustion chamber 4 which is also delimited by piston 2 , an intake valve 5 and an exhaust valve 6 . An intake pipe 7 is connected to the intake valve 5 , and an exhaust pipe 8 is connected to the exhaust valve 6 .

[0020] An injection valve 9 and a spark plug 10 protrude into combustion chamber 4 in the region of intake valve 5 and exhaust valve 6 . Fuel can be injected into combustion chamber 4 via injector 9 . The spark plug 10 can be used to ignite the fuel in the combustion chamber 4 at a defined ignition point or ignition angle.

[0021] A rotatable throttle valve 11 is installed in the intake pipe 7 , through which air can be supplied to the intake pipe 7 . The amount of air fed in depends on the angular position of the throttle valve 11 . A catalytic converter 12 is installed in the exhaust pipe 8 and...

Abstract

Described is a combustion engine, especially for a motor vehicle having a combustion chamber in which fuel can be directly injected by an injection valve and ignited by a spark plug in a first operating mode during an intake phase, in a second operating mode during a compression phase or in a third operating mode during the intake and compression phases. The amount of fuel injected during the intake phase is reduced by the control device in the third operating mode in case of knocking in the internal combustion engine (32).

Description

technical field [0001] The invention relates to a method for operating an internal combustion engine, in particular a motor vehicle, in which the fuel is operated in homogeneous mode during the intake phase, in stratified mode during the compression phase or in a combined homogeneous and stratified mode It is injected directly into the combustion chamber and ignited during the intake phase and during the compression phase. The invention also relates to a corresponding controller for an internal combustion engine, in particular a motor vehicle, and a corresponding internal combustion engine, in particular for a motor vehicle. Background technique [0002] A method of this type, a controller of this type and an internal combustion engine of this type are known, for example, from so-called gasoline direct injection systems. The fuel is injected into the combustion chamber of the internal combustion engine in homogeneous operation during the intake phase or in stratified operat...
