This is normally used in Chevrolet Astro vehices, and its function is to control the back flow of exhaust gases to the combustion chamber especially when the air mix is poor, thus helping to minimalize air pollinants. This is necessary to reduce on Nitrogen oxide or Nitric oxide emissions where a part of the exhaust gases are re-circulated in the combustion chamber in order to lower the combustion temperatures and therefore improving on the efficiency of the engine. During the year, Chevrolet Astro has incorporate numerous style EGR Valves beginning with simple orifice jets to a valve that changes its action depending on the coolant temperature and the manifold vacuum. Backpressure transducers may be incorporated in the latest EGR systems as a means of modulating its rate depending on load. While using the EGR Valves in Chevrolet Astro can be effective in achieving the required limit on emissions, it possess the risk of its blockage due to the accumulation of carbon on the engine parts thus needing proper maintenance.
