Abstract
An internal combustion engine for a motor vehicle includes a combustion chamber in which a first tumble-shaped current of a fuel-air mixture is settable. A pre-chamber spark plug is allocated to the combustion chamber which has a pre-chamber which is fluidically connected to the combustion chamber via a plurality of openings where via the plurality of openings a part of the fuel-air mixture flows out of the combustion chamber and into the pre-chamber. The plurality of openings are formed such that the part of the fuel-air mixture that flows into the pre-chamber via the plurality of openings has a second tumble-shaped current where the second tumble-shaped current is opposite to the first tumble-shaped current.
Claims2
An internal combustion engine for a motor vehicle, comprising:
- a combustion chamber in which a first tumble-shaped current of a fuel-air mixture is settable;
- and
- a pre-chamber spark plug allocated to the combustion chamber which has a pre-chamber which is fluidically connected to the combustion chamber via a plurality of openings, wherein via the plurality of openings a part of the fuel-air mixture flows out of the combustion chamber and into the pre-chamber;
- wherein the plurality of openings are formed such that the part of the fuel-air mixture that flows into the pre-chamber via the plurality of openings has a second tumble-shaped current and wherein the second tumble-shaped current is opposite to the first tumble-shaped current;
- wherein the first tumble-shaped current rotates around a first axis of rotation and the second tumble-shaped current rotates around a second axis of rotation;
- wherein the first and second axes of rotation have an angular deviation that is at most 30 degrees.
