ABSTRACT:
In a method of forming a fuel/air mixture in an internal combustion engine with direct fuel injection, wherein a combustion air flow is admitted to each cylinder through at least one intake passage tangentially to the cylinder wall such that a combustion air spin flow about the cylinder axis is formed in the combustion chamber and fuel is injected into the combustion chamber in a fuel beam extending along the cylinder axis, at least one additional fluid stream is added to the combustion air flow in the intake passage at the side of the intake passage opposite the direction of the spin flow in the combustion chamber so as to provide an additional spin impulse to the combustion air in the combustion chamber.
