Pulse Air Injection System: Description

Pulse air injection system is used to inject fresh air into exhaust system. When fresh air is injected into hot exhaust gases, combustion takes place. This reduces amount of unburned fuel that escapes into the atmosphere.

System consists of check valves, control valves, control valve solenoids, vacuum reservoir, vacuum lines and air lines. Pulse air system is capable of injecting air at both catalytic converter (downstream) or at front exhaust pipe.
