Abstract
A fuel injection system for GDI internal combustion engines, which has a second injection valve in the intake tube, and a method for operating this fuel injection system. By injecting fuel into the intake tube at intervals by means of the second injection valve, the formation of deposits in the intake tube and on the inlet valve, which are produced due to the recirculation of exhaust gas through the exhaust recirculation tube, can be prevented and possibly existing deposits can be broken down.
