Exhaust Emissions System - Air Injection System: Description
NOTE:
For 1974-78 models, see
AIR INJECTION SYSTEMS article in this section.
The air injection system is designed to lower exhaust emissions by creating an afterburning of exhaust gases in the exhaust system. This is done by injecting fresh air into the exhaust ports. Systems consist of air intake filter, air pump, relief valve, diverter valve, deceleration valve, check valve and air shut-off valve (if equipped).
