The EGR Valve in Buick Regal is an important component as it relates to the recycling of exhaust gases back in the combustion chamber so as to lower the formation of nitrogen oxide (NOx). The EGR Valve re-circulates a portion of exhaust gas to reduce oxygen content and mixes it with some inert gases which have a heat absorbing capacity hence reducing the peak temperatures responsible for the formation of NOx. Most importantly this mechanism is useful in achieving the required emissions besides increasing the engine efficiency since there are no limits to the throttle size as well as avoiding pumping losses. Throughout the generations of Buick Regal models, there were utilized the mechanical orifice jets and EGR Valves that are made to respond to engine conditions such as coolant temperature and manifold vacuum. Some of today's EGR systems utilize backpressure transducers to control the flow as per the load demanded from the engine. However, EGR Valves used in Buick Regal vehicles functions well with the only disadvantage of depositing carbon, and therefore should be often cleaned.
