摘要： In a method for operating a spark-ignition internal combustion engine with direct fuel injection in the post-start phase at low temperatures, fuel is supplied to the combustion air in a pilot injection (MH) of a first fuel quantity during an intake stroke of the internal combustion engine such that the pilot injection (MH) forms a homogeneous, lean air/fuel mixture (λ>1) in substantially the entire combustion chamber, and a main injection (MS) of a second fuel quantity is subsequently injected into the combustion chamber during a compression stroke directly before the ignition time (ZT), said main injection (MS) forming in the region of the spark plug a stratified, rich air/fuel mixture (λ
