Abstract

What follows is a description of a fuel injection system for an internal combustion engine which employs exhaust gas recycling. The engine has a suction tube leading to the engine and an exhaust pipe leading from the engine, while the system includes a recycle line connecting both the exhaust pipe and the suction tube, and a control mechanism. The control mechanism can be located either in the suction tube, the exhaust line or the recycle line and controls the pressure therein in order to control the recycled exhaust gas flow rate. The system further has a regulating structure which regulates the quantity of the injected fuel in conjunction with the control mechanism.
