Air Injection Check Valve: Description and Operation
Pulse Air Check Valve:
The pulse air check valve allows air inlet from the air cleaner, through the silencer, and into the exhaust stream, at the exhaust manifold or at the
catalytic converter. A reed valve inside the check valve opens to admit air and closes when exhaust pressure exceeds air cleaner air pressure.
