ABSTRACT:
Disclosed is a cylinder control system for a multicylinder internal combustion engine equipped with an exhaust gas purification device. This system has a valve control circuit which controls the number of fuel injection valves opened and closed, according to the load conditions of the engine. A detector is provided for determining the temperature in the exhaust gas purification device to generate a signal indicative of the temperature. A comparator compares the temperature signal with a reference value to generate, for the valve control circuit, a second signal indicative of whether the determined temperature is higher than a predetermined value. When the determined temperature is higher than the predetermined value, the second signal causes the valve control circuit to close the fuel injection valve or valves which thus far have been opened.
