Air Injection Systems: Notes
WARNING: This page is about a different car, the 1995 Lincoln Mark VIII. However, it is still accessible from the selected car via links, so may be relevant.
The air injection system reduces carbon monoxide (CO) and hydrocarbon (HC) content of exhaust gases. It injects fresh air into the exhaust gas stream, which continues combustion of unburned gases. Individual systems may vary in number and types of components, depending on engine size and application.
