Abstract
A fuel injection method for internal combustion engines with gasoline direct fuel injection systems comprises receiving a crankshaft position signal from a crankshaft position sensor. A position of a crankshaft is determined from the crankshaft position signal. Fuel is commanded at a first rate when the position of the crankshaft is within a first selectable range during a combustion cycle of an engine cylinder and fuel is commanded at a second rate when the position of the crankshaft is within a second selectable range during the combustion cycle of the engine cylinder.
