Abstract

A control system for an internal combustion engine includes a heat flux sensor arranged in the combustion chamber of the engine, for detecting the heat flux within the combustion chamber. An ECU controls at least one of the amount of fuel supplied to the engine, the fuel injection timing, and the ignition timing of the engine according to operating conditions of the engine. The heat flux sensor detects the heat flux at timing within a range from the latter half of the exhaust stroke of each of the cylinders of the combustion cycle of the engine to the first half of the compression stroke of the following combustion cycle. At least one of the amount of fuel, the fuel injection timing, and the ignition timing is corrected based on the detected heat flux in the same stroke as the compression stroke of the following combustion cycle in which the heat flux has been detected.
