They include the EGR Valve, found in Cadillac DeVille vehicles, whose work is to control the means by which exhausted gases re-circulate into the combustion chamber when the AF ratio is off and therefore reducing air pollutants. This technique contributes to an improvement in nitrogen oxide emissions since exhaust gas is recycled and this leads to a reduction in O2 concentration and the maximum temperature. Over the years EGR technology has evolved from simple jets to complex valves triggered by the engine state. Such systems in the modern automobiles may comprise of backpressure transducers to enhance the flow of EGR. I understand that for compliance with emission legislation EGR is crucial; however, there are some new engines like Chrysler Pentastar 3.6 that do not use EGR. The carbon deposits must be removed by timely servicing so that they do not block the flow of EGR valve.
