ABSTRACT:
An after-burner heated catalyst control system and associated control circuit for controlling operation of an after-burner heated catalyst. The control circuit has an air pump motor, a spark plug, and a fuel injector, while the catalyst is disposed within an exhaust passageway of the engine. The control circuit further includes an apparatus for controlling operation of and pulse wave modulating the air pump motor, one spark plug, and fuel injector. An RS232 interface is provided for transmitting and receiving data from and to the control circuit. In addition a method is provided for controlling a temperature of an after-burner heated catalyst and adjusting adaptively the pulse wave modulation of the air pump motor, spark plug, and fuel injector.
