Air Suction System: Description

The air suction system uses exhaust gas pulses to draw air into the exhaust manifold which helps to complete oxidation of emissions. This system includes reed valve, and hoses.

Federal vehicles also use a vacuum control valve (VCV), vacuum transmitting valve (VTV), air switching valve (ASV), and a resonator.

California vehicles use an electronic air control valve (EACV), thermo switch, vacuum switch and a resonator.
