Abstract

A secondary air supply system for an internal combustion engine for suppressing combustion when a throttle valve is fully closed. A secondary air supply system is controlled with a microprocessor which controls other circuits such as the vehicle ignition circuit. Sensors provide outside air temperature data, internal pressure and engine rpm to the microprocessor. The microprocessor addresses the memory based on a computation including these sensed values. The memory in turn controls valves in a secondary air supply system.
