Abstract
An internal combustion engine is disclosed which comprises first and second cylinder units each including at least one cylinder, a control circuit responsive to engine load for supplying a mixture of an optimum air/fuel ratio to the first and second cylinder units and for terminating the supply of the mixture to the second cylinder unit when the engine load is below a given value, and an exhaust system having therein a catalytic converter. An emergency circuit is provided for forcing the control circuit to lean out the air/fuel ratio in response to an increase in the temperature of the catalytic converter.
