Air Injection System - CALIF: Description

The air pump air injection system is designed to reduce hydrocarbon (HC) and carbon monoxide (CO) content of exhaust gases by injecting a controlled amount of compressed air into the exhaust manifold.

Typical components of the system are: a belt-driven air pump with integral relief valve, air control valve with integral relief valves, air by-pass valve, vacuum delay valve, water thermo valve, check valve and various hoses and piping. Models with Auto. Trans. (A/T) also utilize a water thermo switch and ACV solenoid valve (Air Control Valve Solenoid).
