ABSTRACT:
In an exhaust emission control system for an automotive internal combustion engine, an air control valve assembly either directs air flow provided by an engine driven air pump to the engine exhaust ports or to an exhaust system catalytic converter, or diverts the air flow away from the exhaust system. The air control valve assembly has a single diaphragm with three independent diaphragm valve elements, each operated by the air pump discharge pressure.
