Aspirator Air System: Description

The aspirator air system consists of an aspirator valve and an aspirator tube assembly. The valve uses exhaust pressure pulsation to draw air into the exhaust system to reduce carbon monoxide (CO), and hydrocarbon (HC) emissions. The tube assembly connects the aspirator valve to the air cleaner at one end, and the exhaust manifold at the other end.
