ABSTRACT:
An internal combustion engine is proposed which operates on a lean fuel-air mixture. The engine comprises an inlet channel which leads to the cylinder with a piston and which opens into the cylinder via an inlet valve. A flap element pivotably mounted about a pivot axis which is seated on one side is disposed in a section of the inlet channel; said section having a rectangular cross-section. The flap also has a rectangular cross-section and is used to produce a rotating flow in the cylinder in operating states other than full load. Displacement of the flap can be effected against the force of a spring by the suction air or by a servomotor controlled by an electronic control device as a function of the operating parameters of the internal combustion engine such as rpm flap position and temperature. The fuel is injected by means of an injection valve downstream of the flap such that when the inlet valve is open there will be formed in a depression in the piston firstly a horizontal layer of a rich fuel-air mixture which can be ignited by a spark plug and above it leaner mixture layers.
