    Abstract: A control system for an internal combustion engine having an exhaust gas recirculation device for recirculating a part of exhaust gases to an intake system of the engine is disclosed. An estimated exhaust gas recirculation amount is calculated using a neural network to which at least one engine operating parameter indicative of an operating condition of the engine is input. The neural network outputs an estimated value of an amount of exhaust gases recirculated by the exhaust gas recirculation device. At least one engine control parameter for controlling the engine is calculated based on the estimated exhaust gas recirculation amount.

In the exhaust purification apparatus (2), a urea selective reduction catalyst (23) comprises a first selective reduction catalyst (231) and, provided downstream of the first selective reduction catalyst (231) in an exhaust passageway (11), a second selective reduction catalyst (232). Further, the exhaust purification apparatus (2) includes a urea injection unit (25) for feeding of a reducing agent upstream of the urea selective reduction catalyst (23) in the exhaust passageway (11) and an ammonia sensor (26) for detection of the ammonia concentration at a site between the first selective reduction catalyst (231) and the second selective reduction catalyst (232) in the exhaust passageway (11). The rate of urea injection, GUREA, by the urea injection unit (25) is determined so that the value of ammonia concentration, NH3CONS, detected by the ammonia sensor (26) is greater than “0.”
