Method for mixture formation in a direct-injection spark-ignited internal combustion engine and internal combustion engine for carrying out such a method

摘要

The invention relates to a method for mixture formation in a direct-injection spark-ignited internal combustion engine, in which each cylinder on an inlet side has at least one inlet opening for supplying the charge air and on an outlet side at least one outlet opening for discharging the combustion gases, each cylinder a combustion chamber and - the crankshaft is articulated to the piston (1) of each cylinder, wherein the fuel is introduced by means of an injector in the context of at least one injection directly into the at least one cylinder, wherein the injection device in the cylinder head on the opposite side of Piston bottom (1 a) is arranged, in a central plane (5) which is perpendicular to the axis of rotation of the crankshaft and in which the piston longitudinal axis (1 b), and the spark ignition is initiated by means arranged in this center plane (5) ignition device, wherein that the Ansa is formed for the purpose of a charge movement in the combustion chamber of the at least one cylinder in such a way that a tumble (14) is generated in the combustion chamber as part of a charge exchange, wherein the via the open inlet opening into the combustion chamber entering charge air (11 a) - Is directed to the outlet side (3), - is guided in the following outlet side along the cylinder tube (12) in the direction of the piston (1), - then passed from the outlet side (3) via the piston head (1a) in the direction of the inlet side (4) is, and - finally inlet side along the cylinder tube (12) in the direction of the cylinder head (13) and thus directed in the direction of the centrally disposed injection device.
