Abstract
A spark-ignition multiple cylinder internal combustion engine for an automotive vehicle, comprising a first set of cylinders operative on a relatively rich air-fuel mixture and a second set of cylinders operative on a relatively lean air-fuel mixture and having a thermal reactor incorporated into the exhaust system, the internal combustion engine being characterized by a comprehensive emission control system uniting various subsystems of the engine such as the air-intake, mixture induction, exhaust and ignition systems which are provided with means for cooling the thermal reactor by forced air in response to an unusual rise of the temperature of the thermal reactor, means for warming up air in the air-intake system at a rate related to engine load and the temperature of air in the intake system, means for supplying secondary air in accordance with the varying operating conditions of the engine, and means for retarding ignition timing during driving a cold engine.
