ABSTRACT:
A multicylinder internal combustion engine is provided with a means for disabling several cylinders when reduced power can adequately operate the vehicle and an exhaust gas treatment device. An additional fuel injector is provided to increase fuel quantity when the temperature within the treatment device falls below its operating temperature to compensate for the temperature reduction due to the sucking of air to the exhaust system through the disabled cylinders.
