摘要：
In an exhaust gas recirculation system for an internal combustion engine, the flow quantity of exhaust gases recirculated from an exhaust pipe into an induction pipe through a recirculation pipe is controlled in relation to exhaust pressure in the recirculation pipe in accordance with pneumatic pressure defined by a value calculated in a digital computer taking account of negative pressure in the induction pipe and rotational speed of the engine.
