Exhaust Emissions System - Air Injection System: Description

The air injection system reduces exhaust emissions by burning the hydrocarbon (HC) and carbon monoxide (CO) concentrations in the exhaust ports of the cylinder head. System consists of a belt-driven air pump, anti-afterburn valve, air by-pass valve assembly, air by-pass solenoid valve, check valve, vacuum switch, delay valve, choke switch, and various connecting tubes and hoses.
