摘要： A control system for an internal combustion engine, which is capable of enhancing the accuracy of fuel control and ignition timing control even when there is a possibility that the reliability of a calculated intake air amount lowers, and enables reduction of manufacturing costs. An ECU of the control system calculates a first estimated intake air amount according to a valve lift, a cam phase, and a compression ratio, calculates a second estimated intake air amount according to the flow rate of air detected by an air flow sensor. The ECU determines a fuel injection amount according to the first estimated intake air amount when an estimated flow rate Gin_vt calculated based on an engine speed, the valve lift, the cam phase, and the compression ratio is within the range of Gin_vt≦Gin1, and according to the second estimated intake air amount when Gin2≦Gin_vt.

摘要： An in-cylinder pressure sensor for outputting a signal corresponding to an internal cylinder pressure of an engine is provided. A first signal and a second signal are extracted from the output signal of the in-cylinder pressure sensor. The first signal has a frequency band corresponding to knocking of the engine. The second signal has a frequency band used for detecting a peak of the internal cylinder pressure. A knocking detection period is set based on the second signal. The first signal in the knocking detection period is examined to determine whether or not knocking has occurred.
